Cardiac
The nurse is teaching a group of teens about prevention of heart disease. Which point should the nurse emphasize? Reduce abdominal fat. Avoid stress. Do not smoke or chew tobacco. Avoid alcoholic beverages.
Do not smoke or chew tobacco. Tobacco exposure, including secondhand smoke, reduces coronary blood flow; causes vasoconstriction, endothelial dysfunction, and thickening of the vessel walls; increases carbon monoxide; and decreases oxygen. Because it is highly addicting, beginning smoking in the teen years may lead to decades of exposure. Teens are not likely to experience metabolic syndrome from obesity, but are very likely to use tobacco. Avoiding stress is a less modifiable risk factor, which is less likely to cause heart disease in teens. The risk of smoking outweighs the risk of alcohol use.
Which atypical symptoms may be present in a female client experiencing myocardial infarction (MI)? (Select all that apply.) Sharp, inspiratory chest pain Dyspnea Dizziness Extreme fatigue Anorexia
Dyspnea Dizziness Extreme fatigue Many women who experience an MI present with dyspnea, light-headedness, and fatigue. Sharp, pleuritic pain is more consistent with pericarditis or pulmonary embolism. Anorexia is neither a typical nor an atypical sign of MI.
After thrombolytic therapy, the nurse working in the cardiac catheterization laboratory would be alarmed to notice which sign? A 1-inch backup of blood in the IV tubing Facial drooping Partial thromboplastin time (PTT) 68 seconds Report of chest pressure during dye injection
Facial drooping During and after thrombolytic administration, the nurse observes for any indications of bleeding, including changes in neurologic status, which may indicate intracranial bleeding. A 1-inch backup of blood in the IV tubing may be related to IV positioning. If heparin is used, PTT reflects a therapeutic value. Reports of chest pressure during dye injection or stent deployment are considered an expected result of the procedure.
Which characteristics place women at high risk for myocardial infarction (MI)? (Select all that apply.) Premenopausal Increasing age Family history Abdominal obesity Breast cancer
Increasing age Family history Abdominal obesity Increasing age is a risk factor, especially after 70 years. Family history is a significant risk factor in both men and women. A large waist size and/or abdominal obesity are risk factors for both metabolic syndrome and MI. Premenopausal women are not at higher risk for MI, and breast cancer is not a risk factor for MI.
The visiting nurse is seeing a client postoperative for coronary artery bypass graft. Which nursing action should be performed first? Assess coping skills. Assess for postoperative pain at the client's incision site. Monitor for dysrhythmias. Monitor mental status.
Monitor for dysrhythmias. Dysrhythmias are the leading cause of prehospital death; the nurse should monitor the client's heart rhythm. Assessing mental status, coping skills, or postoperative pain is not the priority for this client.
When planning care for a client in the emergency department, which interventions are needed in the acute phase of myocardial infarction? (Select all that apply.) Morphine sulfate Oxygen Nitroglycerin Naloxone Acetaminophen Verapamil (Calan, Isoptin)
Morphine sulfate Oxygen Nitroglycerin Morphine is needed to reduce oxygen demand, preload, pain, and anxiety, and nitroglycerin is used to reduce preload and chest pain. Administering oxygen will increase available oxygen for the ischemic myocardium. Naloxone is a narcotic antagonist that is used for overdosage of opiates, not for MI. Acetaminophen may be used for headache related to nitroglycerin. Because of negative inotropic action, calcium channel blockers such as verapamil are used for angina, not for MI.
A client comes to the emergency department with chest discomfort. Which action does the nurse perform first? Administers oxygen therapy Obtains the client's description of the chest discomfort Provides pain relief medication Remains calm and stays with the client
Obtains the client's description of the chest discomfort A description of the chest discomfort must be obtained first, before further action can be taken. Neither oxygen therapy nor pain medication is the first priority in this situation; an assessment is needed first. Remaining calm and staying with the client are important, but are not matters of highest priority.
The nurse is caring for a client 36 hours after coronary artery bypass grafting, with a priority problem of intolerance for activity related to imbalance of myocardial oxygen supply and demand. Which finding causes the nurse to terminate an activity and return the client to bed? Pulse 60 beats/min and regular Urinary frequency Incisional discomfort Respiratory rate 28 breaths/min
Respiratory rate 28 breaths/min Tachypnea and tachycardia reflect activity intolerance; activity should be terminated. Pulse 60 beats/min and regular is a normal finding. Urinary frequency may indicate infection or diuretic use, but not activity intolerance. Pain with activity after surgery is anticipated; pain medication should be available.
After receiving change-of-shift report in the coronary care unit, which client does the nurse assess first? The client with acute coronary syndrome who has a 3-pound weight gain and dyspnea The client with percutaneous coronary angioplasty who has a dose of heparin scheduled The client who had bradycardia after a myocardial infarction and now has a paced heart rate of 64 beats/min A client who has first-degree heart block, rate 68 beats/min, after having an inferior myocardial infarction
The client with acute coronary syndrome who has a 3-pound weight gain and dyspnea Dyspnea and weight gain are symptoms of left ventricular failure and pulmonary edema; this client needs prompt intervention. A scheduled heparin dose does not take priority over dyspnea; it can be administered after the client with dyspnea is taken care of. The client with a pacemaker and a normal heart rate is not in danger. First-degree heart block is rarely symptomatic, and the client has a normal heart rate; the client with dyspnea should be seen first.
The nurse is preparing to teach a client that metabolic syndrome can increase the risk for myocardial infarction (MI). Which signs of metabolic syndrome should the nurse include in the discussion?

Truncal obesity Hypercholesterolemia Glucose intolerance Client taking losartan (Cozaar) A large waist size (excessive abdominal fat causing central obesity)—40 inches (102 cm) or greater for men, 35 inches (88 cm) or greater for women—is a sign of metabolic syndrome. Decreased high-density lipoprotein cholesterol (HDL-C) (usually with high low-density lipoprotein cholesterol)—HDL-C less than 40 mg/dL for men or less than 50 mg/dL for women—or taking an anticholesterol drug is a sign of metabolic syndrome. Increased fasting blood glucose (caused by diabetes, glucose intolerance, or insulin resistance) is included in the constellation of metabolic syndrome. Blood pressure greater than 130/85 mm Hg or taking antihypertensive medication indicates metabolic syndrome. Although elevated homocysteine levels may predispose to atherosclerosis, they are not part of metabolic syndrome.

b. Anterior wall Due to the large size of the anterior wall, the amount of tissue infarction may be large enough to decrease the force of contraction, leading to heart failure. The client with an inferior wall MI is more likely to develop right ventricular heart failure. Clients with obstruction of the circumflex artery may experience a lateral wall MI and sinus dysrhythmias or a posterior wall MI and sinus dysrhythmias.
A client has just returned from coronary artery bypass graft surgery. For which finding does the nurse contact the surgeon? a. Temperature 98.2° F b. Chest tube drainage 175 mL last hour c. Serum potassium 3.9 mEq/L d. Incisional pain 6 on a scale of 0 to 10

Although hypothermia is a common problem after surgery, a temperature of 98.2° F is a normal finding. Serum potassium of 3.9 mEq/L is a normal finding. Incisional pain of 6 on a scale of 0 to 10 is expected immediately after major surgery; the nurse should administer prescribed analgesics.
The nurse is concerned that a client who had myocardial infarction (MI) has developed cardiogenic shock. Which findings indicate shock? (Select all that apply.) a. Bradycardia b.

b. Cool, diaphoretic skin c. Crackles in the lung fields e. Anxiety and restlessness The client with shock has cool, moist skin. Because of extensive tissue necrosis, the left ventricle cannot forward blood adequately, resulting in pulmonary congestion and crackles. Because of poor tissue perfusion, a change in mental status, anxiety, and restlessness are expected. All types of shock (except neurogenic) present with tachycardia, not bradycardia. Due to pulmonary congestion, a client with cardiogenic shock typically has tachypnea. Cardiogenic shock does not present with low-grade fever; this would be more likely to occur in pericarditis.
The client in the cardiac care unit has had a large myocardial infarction. How does the nurse recognize onset of left ventricular failure? a. Urine output of 1500 mL on the preceding day b. Crackles in the lung fields c. Pedal edema d. Expectoration of yellow sputum
b. Crackles in the lung fields Manifestations of left ventricular failure and pulmonary edema are noted by listening for crackles and identifying their locations in the lung fields.

The nurse practitioner reads in a patient's chart that a carotid bruit was heard during the last two annual checkups. Today on auscultation, the bruit is not present. How does the nurse practitioner evaluate this data? a. The problem has resolved spontaneously b. There may have been an anomaly in previous findings c. The occlusion of the vessel may have progressed past 90% d. The antiplatelet therapy is working
c
Which category of cardiovascular drugs increases heart rate and contractility? a. Diuretics b. Beta blockers c. Catecholamines d. Benzodiazepines
c
a 65-year-old patient comes to the clinic reporting fatigue. The patient would like to start an exercise program, but thinks "anemia might be causing the fatigue." What is the nurse's first action? a. Advise the patient to start out slowly and gradually build strength and endurance b. Obtain an order for a complete blood count and nutritional profile c. Assess the onset, duration, and circumstances associated with the fatigue d. Perform a physical assessment to include testing of muscle strength and tone.
c
An LPN/LVN is scheduled to work on the inpatient "stepdown" cardiac unit. Which client does the charge nurse assign to the LPN/LVN? a. A 60-year-old who was admitted today for pacemaker insertion because of third-degree heart block and who is now reporting chest pain b. A 62-year-old who underwent open heart surgery 4 days ago for mitral valve replacement and who has a temperature of 38.2° C c. A 66-year-old who has a prescription for a nitroglycerin (Nitro-Dur) patch and is scheduled for discharge to a group home later today d. A 69-year-old who had a stent placed 2 hours ago in the left anterior descending artery and who has bursts of ventricular tachycardia
c. A 66-year-old who has a prescription for a nitroglycerin (Nitro-Dur) patch and is scheduled for discharge to a group home later today The LPN/LVN scope of practice includes administration of medications to stable clients. Third-degree heart block is characterized by a very low heart rate and usually by required pacemaker insertion; the skills of the RN are needed to care for this client. Fever after surgery requires collaboration with the health care provider, which is more consistent with the role of the RN. The client with a recent stent placement and having bursts of ventricular tachycardia is unstable and is showing ventricular irritability; he will need medications and monitoring beyond the scope of practice of the LPN/LVN.
An older adult client, 4 hours after coronary artery bypass graft (CABG), has a blood pressure of 80/50 mm Hg. What action does the nurse take? a. No action is required; low blood pressure is normal for older adults. b. No action is required for postsurgical CABG clients. c. Assess pulmonary artery wedge pressure (PAWP). d. Give ordered loop diuretics.
c. Assess pulmonary artery wedge pressure (PAWP). Decreased preload as exhibited by decreased PAWP could indicate hypovolemia secondary to hemorrhage or vasodilation; hypotension could cause the graft to collapse. Low blood pressure is not normal in older adults or postoperative clients. The cause of hypotension must be found and treated; further action is needed to determine additional interventions. Hypotension could be caused by hypovolemia; giving loop diuretics increases hypovolemia.
The visiting nurse is seeing a client postoperative for coronary artery bypass graft. Which nursing action should be performed first? a. Assess coping skills. b. Assess for postoperative pain at the client's incision site. c. Monitor for dysrhythmias. d. Monitor mental status.
c. Monitor for dysrhythmias. Dysrhythmias are the leading cause of prehospital death; the nurse should monitor the client's heart rhythm. Assessing mental status, coping skills, or postoperative pain is not the priority for this client.
What is included in postprocedural care of a patient after a cardiac catheterization? (SATA) a. Patient remains on bedrest for 12 to 24 hours b. Patient is placed in a high-Fowlers position c. Dressing is assessed for bloody drainage or hematoma d. Peripheral pulses in the affected extremity, as well as skin temperature and color, are monitored with every vital sign check e. Adequate oral and IV fluids are provided for hydration f. Vital signs are monitored every hour for 24 hours
cde
A nurse is monitoring the patient blood pressure and ECG during a stress test. Which parameter indicates the patient should stop exercising? a. Increase in heart rate b. Increase in blood pressure c. ECG showing the PQRS complex d. ECG showing St-segment depression
d
A patient reports severe cramping in the legs while attempting to walk for exercise. The provider diagnoses the patient with intermittent claudication. What does the nurse advise the patient to do? a. Elevate the legs on a pillow b. Buy and wear supportive shoes c. Massage the legs before walking d. Rest the legs in a dependent position
d
The nurse is assessing a patient with suspected CVD. When assessing the precordium, which assessment technique does the nurse begin? a. Percussion b. Palpation c. Auscultation d. Inspection
d
The nurse is performing a dietary assessment on a 45-year-old business executive at risk for CVD. Which assessment method used by the nurse is the most reliable and accurate? a. Ask the patient to identify foods he or she eats that contain sodium, sugar, cholesterol, fiber, and fat b. Ask the patient's spouse, who does the cooking and shopping, to identify the types of foods that are consumed c. Ask the patient how cultural beliefs and economic status influence the choice of food items d. Ask the patient to recall the intake of food, fluids, and alcohol during a typical 24-hour period
d
Which exercise regimen for an older adult meets the recommended guidelines of physical fitness to promote heart health? a. 6-hour bike ride every Saturday b. Golfing for 4 hours two times a week c. Running for 15 minutes three times a week d. Brisk walk 30 minutes every day
d
Which medications will the nurse be sure to hold until after a patient's cardiac catheterization? a. Daily vitamin and enteric coated aspirin b. Atenolol and IV antibiotic c. Potassium and folic acid d. Digoxin and furosemide
d
Which patient has an abnormal heart sound? a. S1 in a 45-year-old pateint b. S2 in a 30-year-old patient c. S3 in a 15-year-old patient d. S3 in a 54-year-old patient
d
While listening to a patient's heart sounds, the nurse detects a murmur. What does the nurse understand about the cause of murmurs? a. A murmur is caused by the closing of the aortic and pulmonic valves b. A murmur is caused when blood flows from the atrium to a noncompliant ventricle c. A murmur is caused by anemia, hypertension, or ventricular hypertrophy d. A murmur is caused when there is turbulent blood flow through normal or abnormal valves
d
Which statement by a client scheduled for a percutaneous transluminal coronary angioplasty (PTCA) indicates a need for further preoperative teaching? a. "I will be awake during this procedure." b. "I will have a balloon in my artery to widen it." c. "I must lie still after the procedure." d. "My angina will be gone for good."
d. "My angina will be gone for good." Reocclusion is possible after PTCA. The client is typically awake, but drowsy, during this procedure. PTCA uses a balloon to widen the artery, and the client will have to lie still after the procedure because of the large-bore venous access. Time is necessary to allow the hole to heal and prevent hemorrhage.
To validate that a client has had a myocardial infarction (MI), the nurse assesses for positive findings on which tests? a. Creatine kinase-MB fraction (CK-MB) and alkaline phosphatase b. Homocysteine and C-reactive protein c. Total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol d. CK-MB and troponin
d. CK-MB and troponin CK-MB and troponin are the cardiac markers used to determine whether MI has occurred. Alkaline phosphatase is often elevated in liver disease. Homocysteine and C-reactive protein are markers of inflammation, which may represent risk for MI, but they are not diagnostic for MI. Elevated cholesterol levels are risks for MI, but they do not validate that an MI has occurred.
The nurse is caring for a client 36 hours after coronary artery bypass grafting, with a priority problem of intolerance for activity related to imbalance of myocardial oxygen supply and demand. Which finding causes the nurse to terminate an activity and return the client to bed? a. Pulse 60 beats/min and regular b. Urinary frequency c. Incisional discomfort d. Respiratory rate 28 breaths/min
d. Respiratory rate 28 breaths/min Tachypnea and tachycardia reflect activity intolerance; activity should be terminated. Pulse 60 beats/min and regular is a normal finding. Urinary frequency may indicate infection or diuretic use, but not activity intolerance. Pain with activity after surgery is anticipated; pain medication should be available.

Which statement by a client scheduled for a percutaneous transluminal coronary angioplasty (PTCA) indicates a need for further preoperative teaching? "I will be awake during this procedure." "I will have a balloon in my artery to widen it." "I must lie still after the procedure." "My angina will be gone for good."
"My angina will be gone for good." Reocclusion is possible after PTCA. The client is typically awake, but drowsy, during this procedure. PTCA uses a balloon to widen the artery, and the client will have to lie still after the procedure because of the large-bore venous access. Time is necessary to allow the hole to heal and prevent hemorrhage.
30. Which client teaching should the nurse implement for the client diagnosed with coronary artery disease? Select all that apply. 1. Encourage a low-fat, low-cholesterol diet. 2. Instruct the client to walk 30 minutes a day. 3. Decrease the salt intake to two (2) g a day. 4. Refer to a counselor for stress reduction techniques. 5. Teach the client to increase fiber in the diet.
1. A low-fat, low-cholesterol diet will help decrease the buildup of atherosclerosis in the arteries. 2. Walking will help increase collateral circulation. 4. Stress reduction is encouraged for clients with CAD because this helps prevent excess stress on the heart muscle. 5. Increasing fiber in the diet will help remove cholesterol via the gastrointestinal system. TEST-TAKING HINT: This is an alternate-type question where the test taker must select all interventions that are applicable to the situation. Coronary artery disease is a common disease, and the nurse must be knowledgeable about ways to modify risk factors.
20. The intensive care department nurse is assessing the client who is 12 hours post-myocardial infarction. The nurse assesses an S3 heart sound. Which intervention should the nurse implement? 1. Notify the health-care provider immediately. 2. Elevate the head of the client's bed. 3. Document this as a normal and expected finding. 4. Administer morphine intravenously.
1. An S3 indicates left ventricular failure and should be reported to the health-care provider. It is a potential life-threatening complication of a myocardial infarction. TEST-TAKING HINT: There are some situations in which the nurse must notify the healthcare provider, and the test taker should not automatically eliminate this as a possible correct answer. The test taker must decide if any of the other three options will help correct a life-threatening complication. Normal assessment concepts should help identify the correct option. The normal heart sounds are S1 and S2 ("lubb-dupp"); S3 is abnormal.
34. The client with coronary artery disease is prescribed a Holter monitor. Which intervention should the nurse implement? 1. Instruct the client to keep a diary of activity, especially when having chest pain. 2. Discuss the need to remove the Holter monitor during a.m. care and showering. 3. Explain that all medications should be withheld while wearing a Holter monitor. 4. Teach the client the importance of decreasing activity while wearing the monitor.
1. The Holter monitor is a 24-hour electrocardiogram, and the client must keep an accurate record of activity so that the health-care provider can compare the ECG recordings with different levels of activity. TEST-TAKING HINT: In some instances, the test taker must be knowledgeable about diagnostic tests and there are no test-taking hints. The test taker might eliminate option "3" by realizing that, unless the client is NPO for a test or surgery, medications are usually taken.
23. The client diagnosed with a myocardial infarction asks the nurse, "Why do I have to rest and take it easy? My chest doesn't hurt anymore." Which statement would be the nurse's best response? 1. "Your heart is damaged and needs about four (4) to six (6) weeks to heal." 2. "There is necrotic myocardial tissue that puts you at risk for dysrhythmias." 3. "Your doctor has ordered bedrest. Therefore, you must stay in the bed." 4. "Just because your chest doesn't hurt anymore doesn't mean you are out of danger."
1. The heart tissue is dead, stress or activity may cause heart failure, and it does take about six (6) weeks for scar tissue to form. TEST-TAKING HINT: When attempting to answer a client's question, the nurse should provide factual information in simple, understandable terms. The test taker should select the answer option that provides this type of information.
26. The client with coronary artery disease asks the nurse, "Why do I get chest pain?" Which statement would be the most appropriate response by the nurse? 1. "Chest pain is caused by decreased oxygen to the heart muscle." 2. "There is ischemia to the myocardium as a result of hypoxemia." 3. "The heart muscle is unable to pump effectively to perfuse the body." 4. "Chest pain occurs when the lungs cannot adequately oxygenate the blood."
1. This is a correct statement presented in layman's terms. When the coronary arteries cannot supply adequate oxygen to the heart muscle, there is chest pain. TEST-TAKING HINT: The nurse must select the option that best explains the facts in terms a client who does not have medical training can understand.
28. The nurse is preparing to administer a beta blocker to the client diagnosed with coronary artery disease. Which assessment data would cause the nurse to question administering the medication? 1. The client has a BP of 110/70. 2. The client has an apical pulse of 56. 3. The client is complaining of a headache. 4. The client's potassium level is 4.5 mEq/L.
2. A beta blocker decreases sympathetic stimulation to the heart, thereby decreasing the heart rate. An apical rate less than 60 indicates a lower-than-normal heart rate and should make the nurse question administering this medication because it will further decrease the heart rate. TEST-TAKING HINT: If the test taker does not know when to question the use of a certain medication, the test taker should evaluate the options to determine if any options include abnormal data based on normal parameters. This would make the test taker select option "2" because the normal apical pulse in an adult is 60 to 100.
16. The nurse is caring for a client diagnosed with a myocardial infarction who is experiencing chest pain. Which interventions should the nurse implement? Select all that apply. 1. Administer morphine intramuscularly. 2. Administer an aspirin orally. 3. Apply oxygen via a nasal cannula. 4. Place the client in a supine position. 5. Administer nitroglycerin subcutaneously.
2. Aspirin is an antiplatelet medication and should be administered orally. 3. Oxygen will help decrease myocardial ischemia, thereby decreasing pain. TEST-TAKING HINT: This is an alternate-type question that requires the test taker to select all options that are applicable. The test taker must identify all correct answer options to receive credit for a correct answer; no partial credit is given. Remember to read the question carefully—it is not meant to be tricky.
14. Along with persistent, crushing chest pain, which signs/symptoms would make the nurse suspect that the client is experiencing a myocardial infarction? 1. Midepigastric pain and pyrosis. 2. Diaphoresis and cool, clammy skin. 3. Intermittent claudication and pallor. 4. Jugular vein distention and dependent edema.
2. Diaphoresis (sweating) is a systemic reaction to the MI. The body vasoconstricts to shunt blood from the periphery to the trunk of the body; this, in turn, leads to cold, clammy skin. TEST-TAKING HINT: The stem already addresses chest pain; therefore, the test taker could eliminate option "1" as a possible answer. Intermittent claudication, option "3," is the classic sign of arterial occlusive disease, and JVD is very specific to congestive heart failure. The nurse must be able to identify at least two or three signs/symptoms of disease processes.
29. Which intervention should the nurse implement when administering a loop diuretic to a client diagnosed with coronary artery disease? 1. Assess the client's radial pulse. 2. Assess the client's serum potassium level. 3. Assess the client's glucometer reading. 4. Assess the client's pulse oximeter reading.
2. Loop diuretics cause potassium to be lost in the urine output. Therefore, the nurse should assess the client's potassium level, and if the client is hypokalemic, the nurse should question administering this medication. TEST-TAKING HINT: Knowing that diuretics increase urine output would lead the test taker to eliminate glucose level and oxygenation (options "3" and "4"). In very few instances does the nurse assess the radial pulse; the apical pulse is assessed.
33. The nurse is discussing angina with a client who is diagnosed with coronary artery disease. Which action should the client take first when experiencing angina? 1. Put a nitroglycerin tablet under the tongue. 2. Stop the activity immediately and rest. 3. Document when and what activity caused angina. 4. Notify the health-care provider immediately.
2. Stopping the activity decreases the heart's need for oxygen and may help decrease the angina (chest pain). TEST-TAKING HINT: The question is asking which action the client should take first. This implies that more than one of the answer options could be appropriate for the chest pain, but that only one is done first. The test taker should select the answer that will help the client directly and quickly—and that is stopping the activity.
35. Which statement by the client diagnosed with coronary artery disease indicates that the client understands the discharge teaching concerning diet? 1. "I will not eat more than six (6) eggs a week." 2. "I should bake or grill any meats I eat." 3. "I will drink eight (8) ounces of whole milk a day." 4. "I should not eat any type of pork products."
2. The American Heart Association recommends a low-fat, low-cholesterol diet for a client with coronary artery disease. The client should avoid any fried foods, especially meats, and bake, broil, or grill any meat. TEST-TAKING HINT: The test taker must be knowledgeable of prescribed diets for specific disease processes. This is mainly memorizing facts. There is no test-taking hint to help eliminate any of the options.
18. The client is one (1) day postoperative coronary artery bypass surgery. The client complains of chest pain. Which intervention should the nurse implement first? 1. Medicate the client with intravenous morphine. 2. Assess the client's chest dressing and vital signs. 3. Encourage the client to turn from side to side. 4. Check the client's telemetry monitor.
2. The nurse must always assess the client to determine if the chest pain that is occurring is expected postoperatively or if it is a complication of the surgery. TEST-TAKING HINT: The stem asks the nurse to identify the first intervention that should be implemented. Therefore, the test taker should apply the nursing process and select an assessment intervention. Both options "2" and "4" involve assessment, but the nurse— not a machine or diagnostic test—should always assess the client.
27. The client is scheduled for a right femoral cardiac catheterization. Which nursing intervention should the nurse implement after the procedure? 1. Perform passive range-of-motion exercises. 2. Assess the client's neurovascular status. 3. Keep the client in high Fowler's position. 4. Assess the gag reflex prior to feeding the client.
2. The nurse must make sure that blood is circulating to the right leg, so the client should be assessed for pulses, paresthesia, paralysis, coldness, and pallor. TEST-TAKING HINT: The nurse should apply the nursing process when determining the correct answer. Therefore, either option "2" or option "4" could possibly be the correct answer. The test taker then should apply anatomy concepts—where is the left femoral artery? Neurovascular assessment is performed on extremities.
36. The charge nurse is making assignments for clients on a cardiac unit. Which client should the charge nurse assign to a new graduate nurse? 1. The 44-year-old client diagnosed with a myocardial infarction. 2. The 65-year-old client admitted with unstable angina. 3. The 75-year-old client scheduled for a cardiac catheterization. 4. The 50-year-old client complaining of chest pain.
3. A new graduate should be able to complete a preprocedure checklist and get this client to the catheterization laboratory. TEST-TAKING HINT: "New graduate" is the key to answering this question correctly. What type of client should be assigned to an inexperienced nurse? The test taker should not assign the new graduate a client who is unstable or at risk
19. The client diagnosed with a myocardial infarction is six (6) hours post-right femoral percutaneous transluminal coronary angioplasty (PTCA), also known as balloon surgery. Which assessment data would require immediate intervention by the nurse? 1. The client is keeping the affected extremity straight. 2. The pressure dressing to the right femoral area is intact. 3. The client is complaining of numbness in the right foot. 4. The client's right pedal pulse is 3+ and bounding.
3. Any neurovascular assessment data that are abnormal require intervention by the nurse; numbness may indicate decreased blood supply to the right foot. TEST-TAKING HINT: This question requires the test taker to identify abnormal, unexpected, or life-threatening data. The nurse must know that a PTCA is performed by placing a catheter in the femoral artery and that internal or external bleeding is the most common complication.
17. The client who has had a myocardial infarction is admitted to the telemetry unit from intensive care. Which referral would be most appropriate for the client? 1. Social worker. 2. Physical therapy. 3. Cardiac rehabilitation. 4. Occupational therapy.
3. Cardiac rehabilitation is the most appropriate referral. The client can start rehabilitation in the hospital and then attend an outpatient cardiac rehabilitation clinic, which includes progressive exercise, diet teaching, and classes on modifying risk factors. TEST-TAKING HINT: The test taker must be familiar with the responsibilities of the other members of the health-care team. If the test taker had no idea which would be the most appropriate referral, the word "cardiac," which means "heart," should help the test taker in deciding that this is the most sensible option because the client had a myocardial infarction, a "heart attack."
24. The client has just returned from a cardiac catheterization. Which assessment data would warrant immediate intervention from the nurse? 1. The client's BP is 110/70 and pulse is 90. 2. The client's groin dressing is dry and intact. 3. The client refuses to keep the leg straight. 4. The client denies any numbness and tingling.
3. If the client bends the leg, it could cause the insertion site to bleed. This is arterial blood and the client could bleed to death very quickly, so this requires immediate intervention. TEST-TAKING HINT: "Warrants immediate intervention" means the nurse should probably notify the health-care provider or do something independently because a complication may occur. Therefore, the test taker must select an answer option that is abnormal or unsafe. In the data listed, there are three normal findings and one abnormal finding.
31. The elderly client has coronary artery disease. Which question should the nurse ask the client during the client teaching? 1. "Do you have a daily bowel movement?" 2. "Do you get yearly chest x-rays (CXRs)?" 3. "Are you sexually active?" 4. "Have you had any weight change?"
3. Sexual activity is a risk factor for angina resulting from coronary artery disease. The client's being elderly should not affect the nurse's assessment of the client's concerns about sexual activity. TEST-TAKING HINT: Remember, if the client is described with an adjective such as "elderly," this may be the key to selecting the correct answer. The nurse must not be judgmental about the elderly, especially about issues concerning sexual activity.
15. The client diagnosed with rule-out myocardial infarction is experiencing chest pain while walking to the bathroom. Which action should the nurse implement first? 1. Administer sublingual nitroglycerin. 2. Obtain a STAT electrocardiogram (ECG). 3. Have the client sit down immediately. 4. Assess the client's vital signs.
3. Stopping all activity will decrease the need of the myocardium for oxygen and may help decrease the chest pain. TEST-TAKING HINT: Whenever the test taker wants to select an assessment intervention, be sure to think about whether that intervention will help the client, especially if the client is experiencing pain. Do not automatically select the answer option that is assessment.
22. The client diagnosed with a myocardial infarction is on bedrest. The unlicensed assistive personnel (UAP) is encouraging the client to move the legs. Which action should the nurse implement? 1. Instruct the UAP to stop encouraging the leg movements. 2. Report this behavior to the charge nurse as soon as possible. 3. Praise the UAP for encouraging the client to move the legs. 4. Take no action concerning the UAP's behavior
3. The nurse should praise and encourage UAPs to participate in the client's care. Clients on bedrest are at risk for deep vein thrombosis, and moving the legs will help prevent this from occurring. TEST-TAKING HINT: This is a management question. The test taker must know the chain of command and when to report behavior. The test taker could eliminate options "1" and "2" with the knowledge that moving the legs is a safe activity for the client. When having to choose between options "3" and "4," the test taker should select doing something positive, instead of taking no action. This is a management concept.
13. Which cardiac enzyme would the nurse expect to elevate first in a client diagnosed with a myocardial infarction (MI)? 1. Creatine kinase (CK-MB). 2. Lactate dehydrogenase (LDH). 3. Troponin. 4. White blood cells (WBCs).
3. Troponin is the enzyme that elevates within 1 to 2 hours. TEST-TAKING HINT: The test taker should be aware of the words "cardiac enzyme," which would eliminate option "4" as a possible answer. The word in the stem is "first." This questionrequires the test taker to have knowledge of laboratory values.
32. The nurse is discussing the importance of exercise with the client diagnosed with coronary artery disease. Which intervention should the nurse implement? 1. Perform isometric exercises daily. 2. Walk for 15 minutes three (3) times a week. 3. Do not walk outside if it is less than 40˚F. 4. Wear open-toed shoes when ambulating.
3. When it is cold outside, vasoconstriction occurs, and this will decrease oxygen to the heart muscle. Therefore, the client should not exercise when it is cold outside. TEST-TAKING HINT: The test taker should be aware of adjectives such as "isometric," which makes option "1" incorrect, and "open-toed," which makes option "4" incorrect.
COMPLETION 1. A nurse prepares a client with acute renal insufficiency for a cardiac catheterization. The provider prescribes 0.9% normal saline to infuse at 125 mL/hr for renal protection. The nurse obtains gravity tubing with a drip rate of 15 drops/mL. At what rate (drops/min) should the nurse infuse the fluids? (Record your answer using a whole number, and rounding to the nearest drop.) drops/min
31 drops/min
25. The male client is diagnosed with coronary artery disease (CAD) and is prescribed sublingual nitroglycerin. Which statement indicates the client needs more teaching? 1. "I should keep the tablets in the dark-colored bottle they came in." 2. "If the tablets do not burn under my tongue, they are not effective." 3. "I should keep the bottle with me in my pocket at all times." 4. "If my chest pain is not
4. The client should take one tablet every five (5) minutes and, if no relief occurs after the third tablet, have someone drive him to the emergency department or call 911. TEST-TAKING HINT: This question is an "except" question, requiring the test taker to identify which statement indicates the client doesn't understand the teaching. Sometimes the test taker could restate the question and think which statement indicates the client understands the teaching.
21. The nurse is administering a calcium channel blocker to the client diagnosed with a myocardial infarction. Which assessment data would cause the nurse to question administering this medication? 1. The client's apical pulse is 64. 2. The client's calcium level is elevated. 3. The client's telemetry shows occasional PVCs. 4. The client's blood pressure is 90/58.
4. The client's blood pressure is low, and a calcium channel blocker could cause the blood pressure to bottom out. TEST-TAKING HINT: The test taker must know when to question administering medications. The test taker is trying to select an option that, if the medication is administered, would cause serious harm to the client.
21. A nurse assesses a client who has aortic regurgitation. In which location in the illustration shown below should the nurse auscultate to best hear a cardiac murmur related to aortic regurgitation? a. Location A b. Location B c. Location C d. Location D
A The aortic valve is auscultated in the second intercostal space just to the right of the sternum.
1. A nurse assesses a client who had a myocardial infarction and is hypotensive. Which additional assessment finding should the nurse expect? a. Heart rate of 120 beats/min b. Cool, clammy skin c. Oxygen saturation of 90% d. Respiratory rate of 8 breaths/min
A When a client experiences hypotension, baroreceptors in the aortic arch sense a pressure decrease in the vessels. The parasympathetic system responds by lessening the inhibitory effect on the sinoatrial node. This results in an increase in heart rate and respiratory rate. This tachycardia is an early response and is seen even when blood pressure is not critically low. An increased heart rate and respiratory rate will compensate for the low blood pressure and maintain oxygen saturations and perfusion. The client may not be able to compensate for long, and decreased oxygenation and cool, clammy skin will occur later.
An LPN/LVN is scheduled to work on the inpatient "stepdown" cardiac unit. Which client does the charge nurse assign to the LPN/LVN? A 60-year-old who was admitted today for pacemaker insertion because of third-degree heart block and who is now reporting chest pain A 62-year-old who underwent open heart surgery 4 days ago for mitral valve replacement and who has a temperature of 38.2° C A 66-year-old who has a prescription for a nitroglycerin (Nitro-Dur) patch and is scheduled for discharge to a group home later today A 69-year-old who had a stent placed 2 hours ago in the left anterior descending artery and who has bursts of ventricular tachycardia
A 66-year-old who has a prescription for a nitroglycerin (Nitro-Dur) patch and is scheduled for discharge to a group home later today The LPN/LVN scope of practice includes administration of medications to stable clients. Third-degree heart block is characterized by a very low heart rate and usually by required pacemaker insertion; the skills of the RN are needed to care for this client. Fever after surgery requires collaboration with the health care provider, which is more consistent with the role of the RN. The client with a recent stent placement and having bursts of ventricular tachycardia is unstable and is showing ventricular irritability; he will need medications and monitoring beyond the scope of practice of the LPN/LVN.
1. A nurse is caring for a client with a history of renal insufficiency who is scheduled for a cardiac catheterization. Which actions should the nurse take prior to the catheterization? (Select all that apply.) a. Assess for allergies to iodine. b. Administer intravenous fluids. c. Assess blood urea nitrogen (BUN) and creatinine results. d. Insert a Foley catheter. e. Administer a prophylactic antibiotic. f. Insert a central venous catheter.
A, B, C If the client has kidney disease (as indicated by BUN and creatinine results), fluids and Mucomyst may be given 12 to 24 hours before the procedure for renal protection. The client should be assessed for allergies to iodine, including shellfish; the contrast medium used during the catheterization contains iodine. A Foley catheter and central venous catheter are not required for the procedure and would only increase the clients risk for infection. Prophylactic antibiotics are not administered prior to a cardiac catheterization.
4. A nurse reviews a clients laboratory results. Which findings should alert the nurse to the possibility of atherosclerosis? (Select all that apply.) a. Total cholesterol: 280 mg/dL b. High-density lipoprotein cholesterol: 50 mg/dL c. Triglycerides: 200 mg/dL d. Serum albumin: 4 g/dL e. Low-density lipoprotein cholesterol: 160 mg/dL
A, C, E A lipid panel is often used to screen for cardiovascular risk. Total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels are all high, indicating higher risk for cardiovascular disease. High-density lipoprotein cholesterol is within the normal range for both males and females. Serum albumin is not assessed for atherosclerosis.
6. A nurse cares for a client who is recovering from a right-sided heart catheterization. For which complications of this procedure should the nurse assess? (Select all that apply.) a. Thrombophlebitis b. Stroke c. Pulmonary embolism d. Myocardial infarction e. Cardiac tamponade
A, C, E Complications from a right-sided heart catheterization include thrombophlebitis, pulmonary embolism, and vagal response. Cardiac tamponade is a risk of both right- and left-sided heart catheterizations. Stroke and myocardial infarction are complications of left-sided heart catheterizations.
21. A client is on a dopamine infusion via a peripheral line. What action by the nurse takes priority for safety? a. Assess the IV site hourly. b. Monitor the pedal pulses. c. Monitor the client's vital signs. d. Obtain consent for a central line.
ANS: A Dopamine should be infused through a central line to prevent extravasation and necrosis of tissue. If it needs to be run peripherally, the nurse assesses the site hourly for problems. When the client is getting the central line, ensuring informed consent is on the chart is a priority. But at this point, the client has only a peripheral line, so caution must be taken to preserve the integrity of the client's integumentary system. Monitoring pedal pulses and vital signs give indications as to how well the drug is working.

18. A nurse is caring for a client who is intubated and has an intra-aortic balloon pump. The client is restless and agitated. What action should the nurse perform first for comfort? a. Allow family members to remain at the bedside. b. Ask the family if the client would like a fan in the room. c. Keep the television tuned to the client's favorite channel. d. Speak loudly to the client in case of hearing problems.
ANS: A Allowing the family to remain at the bedside can help calm the client with familiar voices (and faces if the client wakes up). A fan might be helpful but may also spread germs through air movement. The TV should not be kept on all the time to allow for rest. Speaking loudly may agitate the client more.

26. A client had an inferior wall myocardial infarction (MI). The nurse notes the client's cardiac rhythm as shown below: What action by the nurse is most important? a. Assess the client's blood pressure and level of consciousness. b. Call the health care provider or the Rapid Response Team. c. Obtain a permit for an emergency temporary pacemaker insertion. d. Prepare to administer antidysrhythmic medication.
ANS: A Clients with an inferior wall MI often have bradycardia and blocks that lead to decreased perfusion, as seen in this ECG strip showing sinus bradycardia. The nurse should first assess the client's hemodynamic status, including vital signs and level of consciousness. The client may or may not need the Rapid Response Team, a temporary pacemaker, or medication; there is no indication of this in the question.

21. A nurse cares for an older adult client with heart failure. The client states, "I don't know what to do. I don't want to be a burden to my daughter, but I can't do it alone. Maybe I should die." How should the nurse respond? a. "Would you like to talk more about this?" b. "You are lucky to have such a devoted daughter." c. "It is normal to feel as though you are a burden." d. "Would you like to meet with the chaplain?"
ANS: A Depression can occur in clients with heart failure, especially older adults. Having the client talk about his or her feelings will help the nurse focus on the actual problem. Open-ended statements allow the client to respond safely and honestly. The other options minimize the client's concerns and do not allow the nurse to obtain more information to provide client-centered care.

19. A nurse cares for a client who is on a cardiac monitor. The monitor displayed the rhythm shown below: Which action should the nurse take first? a. Assess airway, breathing, and level of consciousness. b. Administer an amiodarone bolus followed by a drip. c. Cardiovert the client with a biphasic defibrillator. d. Begin cardiopulmonary resuscitation (CPR).
ANS: A Ventricular tachycardia occurs with repetitive firing of an irritable ventricular ectopic focus, usually at a rate of 140 to 180 beats/min or more. Ventricular tachycardia is a lethal dysrhythmia. The nurse should first assess if the client is alert and breathing. Then the nurse should call a Code Blue and begin CPR. If this client is pulseless, the treatment of choice is defibrillation. Amiodarone is the antidysrhythmic of choice, but it is not the first action.

"Are your bedroom and bathroom on the first floor?" b. "What social support do you have at home?" c. "Will you be able to afford your oxygen therapy?" d. "What spiritual beliefs may impact your recovery?" e. "Are you able to accurately weigh yourself at home?"
ANS: A, B, D To ensure safety upon discharge, the nurse should assess for structural barriers to functional ability, such as stairs. The nurse should also assess the client's available social support, which may include family, friends, and home health services. The client's ability to adhere to medication and treatments, including daily weights, should also be reviewed. The other questions do not address the client's safety upon discharge.

"If you feel weak, apply pressure over your generator." d. "Have your pacemaker turned off before having magnetic resonance imaging (MRI)." e. "Do not lift your left arm above the level of your shoulder for 8 weeks."
ANS: A, B, E The client should not submerge in water until the site has healed; after the incision is healed, the client may take showers or baths without concern for the pacemaker. The client should be instructed to report changes in heart rate or rhythm, such as rates lower than the pacemaker setting or greater than 100 beats/min. The client should be advised of restrictions on physical activity for 8 weeks to allow the pacemaker to settle in place. The client should never apply pressure over the generator and should avoid tight clothing. The client should never have MRI because, whether turned on or off, the pacemaker contains metal. The client should be advised to inform all health care providers that he or she has a pacemaker.

MULTIPLE RESPONSE 1. A nurse cares for a client with congestive heart failure who has a regular cardiac rhythm of 128 beats/min. For which physiologic alterations should the nurse assess? (Select all that apply.) a. Decrease in cardiac output b. Increase in cardiac output c. Decrease in blood pressure d. Increase in blood pressure e. Decrease in urine output f. Increase in urine output
ANS: A, D, E Elevated heart rates in a healthy client initially cause blood pressure and cardiac output to increase. However, in a client who has congestive heart failure or a client with long-term tachycardia, ventricular filling time, cardiac output, and blood pressure eventually decrease. As cardiac output and blood pressure decrease, urine output will fall.

Initiate cardiopulmonary resuscitation (CPR). c. Start an 18-gauge intravenous line. d. Ask the client's family about code status.
ANS: B The client's rhythm is ventricular fibrillation. This is a lethal rhythm that is best treated with immediate defibrillation. While the nurse is waiting for the defibrillator to arrive, the nurse should start CPR. A pericardial thump is not a treatment for ventricular fibrillation. If the client does not already have an IV, other members of the team can insert one after defibrillation. The client's code status should already be known by the nurse prior to this event.

22. A nurse teaches a client with heart failure about energy conservation. Which statement should the nurse include in this client's teaching? a. "Walk until you become short of breath, and then walk back home." b. "Gather everything you need for a chore before you begin." c. "Pull rather than push or carry items heavier than 5 pounds." d. "Take a walk after dinner every day to build up your strength."
ANS: B A client who has heart failure should be taught to conserve energy. Gathering all supplies needed for a chore at one time decreases the amount of energy needed. The client should not walk until becoming short of breath because he or she may not make it back home. Pushing a cart takes less energy than pulling or lifting. Although walking after dinner may help the client, the nurse should teach the client to complete activities when he or she has the most energy. This is usually in the morning.

"Do you have trouble breathing or chest pain?" b. "Are you able to walk upstairs without fatigue?" c. "Do you awake with breathlessness during the night?" d. "Do you have new-onset heaviness in your legs?"
ANS: B Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night, and peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

20. A home health care nurse is visiting an older client who lives alone after being discharged from the hospital after a coronary artery bypass graft. What finding in the home most causes the nurse to consider additional referrals? a. Dirty carpets in need of vacuuming b. Expired food in the refrigerator c. Old medications in the kitchen d. Several cats present in the home
ANS: B Expired food in the refrigerator demonstrates a safety concern for the client and a possible lack of money to buy food. The nurse can consider a referral to Meals on Wheels or another home-based food program. Dirty carpets may indicate the client has no household help and is waiting for clearance to vacuum. Old medications can be managed by the home health care nurse and the client working collaboratively. Having pets is not a cause for concern.

Cardiac rhythm: normal sinus rhythm. Skin: warm, dry, and appropriate for race. Respirations equal and unlabored. Client denies shortness of breath and chest pain. Time: 1000 Client alert and oriented. Cardiac rhythm: sinus bradycardia. Skin: warm, dry, and appropriate for race. Respirations equal and unlabored. Client denies shortness of breath and chest pain. Client voids 420 mL of clear yellow urine. Based on the assessments, which action should the nurse take? a. Stop the infusion and flush the IV. b. Slow the amiodarone infusion rate. c. Administer IV normal saline. d. Ask the client to cough and deep breathe.
ANS: B IV administration of amiodarone may cause bradycardia and atrioventricular (AV) block. The correct action for the nurse to take at this time is to slow the infusion, because the client is asymptomatic and no evidence reveals AV block that might require pacing. Abruptly ceasing the medication could allow fatal dysrhythmias to occur. The administration of IV fluids and encouragement of coughing and deep breathing exercises are not indicated, and will not increase the client's heart rate.

17. After teaching a client who is recovering from a heart transplant to change positions slowly, the client asks, "Why is this important?" How should the nurse respond? a. "Rapid position changes can create shear and friction forces, which can tear out your internal vascular sutures." b. "Your new vascular connections are more sensitive to position changes, leading to increased intravascular pressure and dizziness." c. "Your new heart is not connected to the nervous system and is unable to respond to decreases in blood pressure caused by position changes." d. "While your heart is recovering, blood flow is diverted away from the brain, increasing the risk for stroke when you stand up."
ANS: C Because the new heart is denervated, the baroreceptor and other mechanisms that compensate for blood pressure drops caused by position changes do not function. This allows orthostatic hypotension to persist in the postoperative period. The other options are false statements and do not correctly address the client's question.

22. A client had an acute myocardial infarction. What assessment finding indicates to the nurse that a significant complication has occurred? a. Blood pressure that is 20 mm Hg below baseline b. Oxygen saturation of 94% on room air c. Poor peripheral pulses and cool skin d. Urine output of 1.2 mL/kg/hr for 4 hours
ANS: C Poor peripheral pulses and cool skin may be signs of impending cardiogenic shock and should be reported immediately. A blood pressure drop of 20 mm Hg is not worrisome. An oxygen saturation of 94% is just slightly below normal. A urine output of 1.2 mL/kg/hr for 4 hours is normal.

23. A client presents to the emergency department with an acute myocardial infarction (MI) at 1500 (3:00 PM). The facility has 24-hour catheterization laboratory abilities. To meet The Joint Commission's Core Measures set, by what time should the client have a percutaneous coronary intervention performed? a. 1530 (3:30 PM) b. 1600 (4:00 PM) c. 1630 (4:30 PM) d. 1700 (5:00 PM)
ANS: C The Joint Commission's Core Measures set for MI includes percutaneous coronary intervention within 90 minutes of diagnosis of myocardial infarction. Therefore, the client should have a percutaneous coronary intervention performed no later than 1630 (4:30 PM).

20. A nurse performs an admission assessment on a 75-year-old client with multiple chronic diseases. The client's blood pressure is 135/75 mm Hg and oxygen saturation is 94% on 2 liters per nasal cannula. The nurse assesses the client's rhythm on the cardiac monitor and observes the reading shown below: Which action should the nurse take first? a. Begin external temporary pacing. b. Assess peripheral pulse strength. c. Ask the client what medications he or she takes. d. Administer 1 mg of atropine.
ANS: C This client is stable and therefore does not require any intervention except to determine the cause of the bradycardia. Bradycardia is often caused by medications. Clients who have multiple chronic diseases are often on multiple medications that can interact with each other. The nurse should assess the client's current medications first.

23. A nurse is caring for a client with acute pericarditis who reports substernal precordial pain that radiates to the left side of the neck. Which nonpharmacologic comfort measure should the nurse implement? a. Apply an ice pack to the client's chest. b. Provide a neck rub, especially on the left side. c. Allow the client to lie in bed with the lights down. d. Sit the client up with a pillow to lean forward on.
ANS: D Pain from acute pericarditis may worsen when the client lays supine. The nurse should position the client in a comfortable position, which usually is upright and leaning slightly forward. Pain is decreased by using gravity to take pressure off the heart muscle. An ice pack and neck rub will not relieve this pain.

18. A nurse assesses a client's electrocardiogram (ECG) and observes the reading shown below: How should the nurse document this client's ECG strip? a. Ventricular tachycardia b. V entricular fibrillation c. Sinus rhythm with premature atrial contractions (PACs) d. Sinus rhythm with premature ventricular contractions (PVCs)
ANS: D Sinus rhythm with PVCs has an underlying regular sinus rhythm with ventricular depolarization that sometimes precede atrial depolarization. Ventricular tachycardia and ventricular fibrillation rhythms would not have sinus beats present. Premature atrial contractions are atrial contractions initiated from another region of the atria before the sinus node initiates atrial depolarization.

19. A nurse cares for a client with end-stage heart failure who is awaiting a transplant. The client appears depressed and states, "I know a transplant is my last chance, but I don't want to become a vegetable." How should the nurse respond? a. "Would you like to speak with a priest or chaplain?" b. "I will arrange for a psychiatrist to speak with you." c. "Do you want to come off the transplant list?" d. "Would you like information about advance directives?"
ANS: D The client is verbalizing a real concern or fear about negative outcomes of the surgery. This anxiety itself can have a negative effect on the outcome of the surgery because of sympathetic stimulation. The best action is to allow the client to verbalize the concern and work toward a positive outcome without making the client feel as though he or she is crazy. The client needs to feel that he or she has some control over the future. The nurse personally provides care to address the client's concerns instead of pushing the client's issues off on a chaplain or psychiatrist. The nurse should not jump to conclusions and suggest taking the client off the transplant list, which is the best treatment option.

25. A nurse is assessing a client who had a myocardial infarction. Upon auscultating heart sounds, the nurse hears the following sound. What action by the nurse is most appropriate? (Click the media button to hear the audio clip.) a. Assess for further chest pain. b. Call the Rapid Response Team. c. Have the client sit upright. d. Listen to the client's lung sounds.
ANS: D The sound the nurse hears is an S3 heart sound, an abnormal sound that may indicate heart failure. The nurse should next assess the client's lung sounds. Assessing for chest pain is not directly related. There is no indication that the Rapid Response Team is needed. Having the client sit up will not change the heart sound.

11. A nurse cares for a client who is prescribed magnetic resonance imaging (MRI) of the heart. The clients health history includes a previous myocardial infarction and pacemaker implantation. Which action should the nurse take? a. Schedule an electrocardiogram just before the MRI. b. Notify the health care provider before scheduling the MRI. c. Call the physician and request a laboratory draw for cardiac enzymes. d. Instruct the client to increase fluid intake the day before the MRI.
B The magnetic fields of the MRI can deactivate the pacemaker. The nurse should call the health care provider and report that the client has a pacemaker so the provider can order other diagnostic tests. The client does not need an electrocardiogram, cardiac enzymes, or increased fluids.
20. A nurse auscultated heart tones on an older adult client. Which action should the nurse take based on heart tones heard? (Click the media button to hear the audio clip.) a. Administer a diuretic. b. Document the finding. c. Decrease the IV flow rate. d. Evaluate the clients medications.
B The sound heard is an atrial gallop S4. An atrial gallop may be heard in older clients because of a stiffened ventricle. The nurse should document the finding, but no other intervention is needed at this time.
2. An emergency room nurse assesses a female client. Which assessment findings should alert the nurse to request a prescription for an electrocardiogram? (Select all that apply.) a. Hypertension b. Fatigue despite adequate rest c. Indigestion d. Abdominal pain e. Shortness of breath
B, C, E Women may not have chest pain with myocardial infarction, but may feel discomfort or indigestion. They often present with a triad of symptomsindigestion or feeling of abdominal fullness, feeling of chronic fatigue despite adequate rest, and feeling unable to catch their breath. Frequently, women are not diagnosed and therefore are not treated adequately. Hypertension and abdominal pain are not associated with acute coronary syndrome.
5. A nurse prepares a client for a pharmacologic stress echocardiogram. Which actions should the nurse take when preparing this client for the procedure? (Select all that apply.) a. Assist the provider to place a central venous access device. b. Prepare for continuous blood pressure and pulse monitoring. c. Administer the clients prescribed beta blocker. d. Give the client nothing by mouth 3 to 6 hours before the procedure. e. Explain to the client that dobutamine will simulate exercise for this examination.
B, D, E Clients receiving a pharmacologic stress echocardiogram will need peripheral venous access and continuous blood pressure and pulse monitoring. The client must be NPO 3 to 6 hours prior to the procedure. Education about dobutamine, which will be administered during the procedure, should be performed. Beta blockers are often held prior to the procedure.
3. A nurse assesses a client who is recovering after a coronary catheterization. Which assessment findings in the first few hours after the procedure require immediate action by the nurse? (Select all that apply.) a. Blood pressure of 140/88 mm Hg b. Serum potassium of 2.9 mEq/L c. Warmth and redness at the site d. Expanding groin hematoma e. Rhythm changes on the cardiac monitor
B, D, E In the first few hours postprocedure, the nurse monitors for complications such as bleeding from the insertion site, hypotension, acute closure of the vessel, dye reaction, hypokalemia, and dysrhythmias. The clients blood pressure is slightly elevated but does not need immediate action. Warmth and redness at the site would indicate an infection, but this would not be present in the first few hours.
an older client has a history of coronary artery disease. which modifiable risk factors will the nurse assess to guide the client's teaching plan? select all that apply. A. older age B. tobacco use C. female D. high-fat diet E. family history F. obesity
B, D, F
the nurse assesses a client who had a coronary artery bypass graft yesterday. which assessment finding will the nurse report to the surgeon immediately? A. incisional pain B. BP of 136/76 C. decreased level of consciousness D. apical pulse of 88
C
7. A nurse assesses an older adult client who is experiencing a myocardial infarction. Which clinical manifestation should the nurse expect? a. Excruciating pain on inspiration b. Left lateral chest wall pain c. Disorientation and confusion d. Numbness and tingling of the arm
C In older adults, disorientation or confusion may be the major manifestation of myocardial infarction caused by poor cardiac output. Pain manifestations and numbness and tingling of the arm could also be related to the myocardial infarction. However, the nurse should be more concerned about the new onset of disorientation or confusion caused by decreased perfusion.
18. A nurse prepares a client for coronary artery bypass graft surgery. The client states, I am afraid I might die. How should the nurse respond? a. This is a routine surgery and the risk of death is very low. b. Would you like to speak with a chaplain prior to surgery? c. Tell me more about your concerns about the surgery. d. What support systems do you have to assist you?
C The nurse should discuss the clients feelings and concerns related to the surgery. The nurse should not provide false hope or push the clients concerns off on the chaplain. The nurse should address support systems after addressing the clients current issue.
To validate that a client has had a myocardial infarction (MI), the nurse assesses for positive findings on which tests? Creatine kinase-MB fraction (CK-MB) and alkaline phosphatase Homocysteine and C-reactive protein Total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol CK-MB and troponin
CK-MB and troponin CK-MB and troponin are the cardiac markers used to determine whether MI has occurred. Alkaline phosphatase is often elevated in liver disease. Homocysteine and C-reactive protein are markers of inflammation, which may represent risk for MI, but they are not diagnostic for MI. Elevated cholesterol levels are risks for MI, but they do not validate that an MI has occurred.
A client has just returned from coronary artery bypass graft surgery. For which finding does the nurse contact the surgeon? Temperature 98.2° F Chest tube drainage 175 mL last hour Serum potassium 3.9 mEq/L Incisional pain 6 on a scale of 0 to 10
Chest tube drainage 175 mL last hour Some bleeding is expected after surgery; however, the nurse should report chest drainage over 150 mL/hr to the surgeon. Although hypothermia is a common problem after surgery, a temperature of 98.2° F is a normal finding. Serum potassium of 3.9 mEq/L is a normal finding. Incisional pain of 6 on a scale of 0 to 10 is expected immediately after major surgery; the nurse should administer prescribed analgesics.
The nurse is concerned that a client who had myocardial infarction (MI) has developed cardiogenic shock. Which findings indicate shock? (Select all that apply.) Bradycardia Cool, diaphoretic skin Crackles in the lung fields Respiratory rate of 12 breaths/min Anxiety and restlessness Temperature of 100.4° F
Cool, diaphoretic skin Crackles in the lung fields Anxiety and restlessness The client with shock has cool, moist skin. Because of extensive tissue necrosis, the left ventricle cannot forward blood adequately, resulting in pulmonary congestion and crackles. Because of poor tissue perfusion, a change in mental status, anxiety, and restlessness are expected. All types of shock (except neurogenic) present with tachycardia, not bradycardia. Due to pulmonary congestion, a client with cardiogenic shock typically has tachypnea. Cardiogenic shock does not present with low-grade fever; this would be more likely to occur in pericarditis.
The client in the cardiac care unit has had a large myocardial infarction. How does the nurse recognize onset of left ventricular failure? Urine output of 1500 mL on the preceding day Crackles in the lung fields Pedal edema Expectoration of yellow sputum
Crackles in the lung fields Manifestations of left ventricular failure and pulmonary edema are noted by listening for crackles and identifying their locations in the lung fields. A urine output of 1500 mL is normal. Edema is a sign of right ventricular heart failure. Yellow sputum indicates the presence of white blood cells and possible infection.
19. An emergency department nurse triages clients who present with chest discomfort. Which client should the nurse plan to assess first? a. A 42-year-old female who describes her pain as a dull ache with numbness in her fingers b. A 49-year-old male who reports moderate pain that is worse on inspiration c. A 53-year-old female who reports substernal pain that radiates to her abdomen d. A 58-year-old male who describes his pain as intense stabbing that spreads across his chest
D All clients who have chest pain should be assessed more thoroughly. To determine which client should be seen first, the nurse must understand common differences in pain descriptions. Intense stabbing, vise-like substernal pain that spreads through the clients chest, arms, jaw, back, or neck is indicative of a myocardial infarction. The nurse should plan to see this client first to prevent cardiac cell death. A dull ache with numbness in the fingers is consistent with anxiety. Pain that gets worse with inspiration is usually related to a pleuropulmonary problem. Pain that spreads to the abdomen is often associated with an esophageal-gastric problem, especially when this pain is experienced by a male client. Female clients may experience abdominal discomfort with a myocardial event. Although clients with anxiety, pleuropulmonary, and esophageal-gastric problems should be seen, they are not a higher priority than myocardial infarction.
15. A nurse cares for a client who has advanced cardiac disease and states, I am having trouble sleeping at night. How should the nurse respond? a. I will consult the provider to prescribe a sleep study to determine the problem. b. You become hypoxic while sleeping; oxygen therapy via nasal cannula will help. c. A continuous positive airway pressure, or CPAP, breathing mask will help you breathe at night. d. Use pillows to elevate your head and chest while you are sleeping.
D The client is experiencing orthopnea (shortness of breath while lying flat). The nurse should teach the client to elevate the head and chest with pillows or sleep in a recliner. A sleep study is not necessary to diagnose this client. Oxygen and CPAP will not help a client with orthopnea.
a client weighing 174 lbs had thrombolytic therapy followed by a one-time dose of IV lovenox 30 mg. the physician prescribes lovenox 1 mg/kg subcutaneously after the IV administration. the nurse will give ____ mg of lovenox to the client.

A client undergoing coronary artery bypass grafting asks why the surgeon has chosen to use the internal mammary artery for the surgery. Which response by the nurse is correct? "This way you will not need to have a leg incision." "The surgeon prefers this approach because it is easier." "These arteries remain open longer." "The surgeon has chosen this approach because of your age."
"These arteries remain open longer." Mammary arteries remain patent much longer than other grafts. Although no leg incision will be made with this approach, veins from the legs do not remain patent as long as the mammary artery graft does. Long-term patency, not ease of the procedure, is the primary concern. Age is not a determining factor in selection of these grafts.
A client with unstable angina has received education about acute coronary syndrome. Which statement indicates that the client has understood the teaching? "This is a big warning; I must modify my lifestyle or risk having a heart attack in the next year." "Angina is just a temporary interruption of blood flow to my heart." "I need to tell my wife I've had a heart attack." "Because this was temporary, I will not need to take any medications for my heart."
"This is a big warning; I must modify my lifestyle or risk having a heart attack in the next year." Among people who have unstable angina, 10% to 30% have a myocardial infarction within 1 year. Although anginal pain is temporary, it reflects underlying coronary artery disease (CAD), which requires attention, including lifestyle modifications. Unstable angina reflects tissue ischemia, but infarction represents tissue necrosis. Clients with underlying CAD may need medications such as aspirin, lipid-lowering agents, anti-anginals, or antihypertensives.
During discharge planning after admission for a myocardial infarction, the client says, "I won't be able to increase my activity level. I live in an apartment, and there is no place to walk." What is the nurse's best response? "You are right. Work on your diet then." "You must find someplace to walk." "Walk around the edge of your apartment complex." "Where might you be able to walk?"
"Where might you be able to walk?" Asking the client where he or she might be able to walk calls for cooperation and participation from the client; increased activity is imperative for this client. Telling the client to work on diet is an inappropriate response. Telling the client to find someplace to walk is too demanding to be therapeutic. Telling the client to walk around the apartment complex is domineering and will not likely achieve cooperation from the client.
5. An emergency room nurse obtains the health history of a client. Which statement by the client should alert the nurse to the occurrence of heart failure? a. I get short of breath when I climb stairs. b. I see halos floating around my head. c. I have trouble remembering things. d. I have lost weight over the past month.
A Dyspnea on exertion is an early manifestation of heart failure and is associated with an activity such as stair climbing. The other findings are not specific to early occurrence of heart failure.
12. A nurse assesses a client who is recovering from a myocardial infarction. The clients pulmonary artery pressure reading is 25/12 mm Hg. Which action should the nurse take first? a. Compare the results with previous pulmonary artery pressure readings. b. Increase the intravenous fluid rate because these readings are low. c. Immediately notify the health care provider of the elevated pressures. d. Document the finding in the clients chart as the only action.
A Normal pulmonary artery pressures range from 15 to 26 mm Hg for systolic and from 5 to 15 mm Hg for diastolic. Although this clients readings are within normal limits, the nurse needs to assess any trends that may indicate a need for medical treatment to prevent complications. There is no need to increase intravenous fluids or notify the provider.
1. A nurse assesses clients on a cardiac unit. Which client should the nurse identify as being at greatest risk for the development of left-sided heart failure? a. A 36-year-old woman with aortic stenosis b. A 42-year-old man with pulmonary hypertension c. A 59-year-old woman who smokes cigarettes daily d. A 70-year-old man who had a cerebral vascular accident
ANS: A Although most people with heart failure will have failure that progresses from left to right, it is possible to have left-sided failure alone for a short period. It is also possible to have heart failure that progresses from right to left. Causes of left ventricular failure include mitral or aortic valve disease, coronary artery disease, and hypertension. Pulmonary hypertension and chronic cigarette smoking are risk factors for right ventricular failure. A cerebral vascular accident does not increase the risk of heart failure.

6. A nurse is teaching a client with heart failure who has been prescribed enalapril (Vasotec). Which statement should the nurse include in this client's teaching? a. "Avoid using salt substitutes." b. "Take your medication with food." c. "Avoid using aspirin-containing products." d. "Check your pulse daily."
ANS: A Angiotensin-converting enzyme (ACE) inhibitors such as enalapril inhibit the excretion of potassium. Hyperkalemia can be a life-threatening side effect, and clients should be taught to limit potassium intake. Salt substitutes are composed of potassium chloride. ACE inhibitors do not need to be taken with food and have no impact on the client's pulse rate. Aspirin is often prescribed in conjunction with ACE inhibitors and is not contraindicated.

ANS: A Assessment of respiratory and oxygenation status is the priority nursing intervention for the prevention of complications. Monitoring electrolytes, administering diuretics, and asking about current medications are important but do not take priority over assessing respiratory status.

14. A nurse assesses a client with tachycardia. Which clinical manifestation requires immediate intervention by the nurse? a. Mid-sternal chest pain b. Increased urine output c. Mild orthostatic hypotension d. P wave touching the T wave
ANS: A Chest pain, possibly angina, indicates that tachycardia may be increasing the client's myocardial workload and oxygen demand to such an extent that normal oxygen delivery cannot keep pace. This results in myocardial hypoxia and pain. Increased urinary output and mild orthostatic hypotension are not life-threatening conditions and therefore do not require immediate intervention. The P wave touching the T wave indicates significant tachycardia and should be assessed to determine the underlying rhythm and cause; this is an important assessment but is not as critical as chest pain, which indicates cardiac cell death.

4. A nursing student is caring for a client who had a myocardial infarction. The student is confused because the client states nothing is wrong and yet listens attentively while the student provides education on lifestyle changes and healthy menu choices. What response by the faculty member is best? a. "Continue to educate the client on possible healthy changes." b. "Emphasize complications that can occur with noncompliance." c. "Tell the client that denial is normal and will soon go away." d. "You need to make sure the client understands this illness."
ANS: A Clients are often in denial after a coronary event. The client who seems to be in denial but is compliant with treatment may be using a healthy form of coping that allows time to process the event and start to use problem-focused coping. The student should not discourage this type of denial and coping, but rather continue providing education in a positive manner. Emphasizing complications may make the client defensive and more anxious. Telling the client that denial is normal is placing too much attention on the process. Forcing the client to verbalize understanding of the illness is also potentially threatening to the client.

"Do you have any concerns about sexuality?" b. "I'm glad to hear you are sleeping well now." c. "Sleep near your spouse in case of emergency." d. "Why would you move into the guest room?"
ANS: A Concerns about resuming sexual activity are common after cardiac events. The nurse should gently inquire if this is the issue. While it is good that the client is sleeping well, the nurse should investigate the reason for the move. The other two responses are likely to cause the client to be defensive.

5. A nurse cares for a client with right-sided heart failure. The client asks, "Why do I need to weigh myself every day?" How should the nurse respond? a. "Weight is the best indication that you are gaining or losing fluid." b. "Daily weights will help us make sure that you're eating properly." c. "The hospital requires that all inpatients be weighed daily." d. "You need to lose weight to decrease the incidence of heart failure."
ANS: A Daily weights are needed to document fluid retention or fluid loss. One liter of fluid equals 2.2 pounds. The other responses do not address the importance of monitoring fluid retention or loss.

11. An older adult is on cardiac monitoring after a myocardial infarction. The client shows frequent dysrhythmias. What action by the nurse is most appropriate? a. Assess for any hemodynamic effects of the rhythm. b. Prepare to administer antidysrhythmic medication. c. Notify the provider or call the Rapid Response Team. d. Turn the alarms off on the cardiac monitor.
ANS: A Older clients may have dysrhythmias due to age-related changes in the cardiac conduction system. They may have no significant hemodynamic effects from these changes. The nurse should first assess for the effects of the dysrhythmia before proceeding further. The alarms on a cardiac monitor should never be shut off. The other two actions may or may not be needed.

"Use your oxygen when you experience PACs." d. "Take amiodarone (Cordarone) daily to prevent PACs."
ANS: A PACs usually have no hemodynamic consequences. For a client experiencing infrequent PACs, the nurse should explore possible lifestyle causes, such as excessive caffeine intake and stress. Lying on the side will not prevent or resolve PACs. Oxygen is not necessary. Although medications may be needed to control symptomatic dysrhythmias, for infrequent PACs, the client first should try lifestyle changes to control them.

13. A nurse prepares to discharge a client with cardiac dysrhythmia who is prescribed home health care services. Which priority information should be communicated to the home health nurse upon discharge? a. Medication reconciliation b. Immunization history c. Religious beliefs d. Nutrition preferences
ANS: A The home health nurse needs to know current medications the client is taking to ensure assessment, evaluation, and further education related to these medications. The other information will not assist the nurse to develop a plan of care for the client.

4. While assessing a client on a cardiac unit, a nurse identifies the presence of an S3 gallop. Which action should the nurse take next? a. Assess for symptoms of left-sided heart failure. b. Document this as a normal finding. c. Call the health care provider immediately. d. Transfer the client to the intensive care unit.
ANS: A The presence of an S3 gallop is an early diastolic filling sound indicative of increasing left ventricular pressure and left ventricular failure. The other actions are not warranted.

7. A client has intra-arterial blood pressure monitoring after a myocardial infarction. The nurse notes the client's heart rate has increased from 88 to 110 beats/min, and the blood pressure dropped from 120/82 to 100/60 mm Hg. What action by the nurse is most appropriate? a. Allow the client to rest quietly. b. Assess the client for bleeding. c. Document the findings in the chart. d. Medicate the client for pain.
ANS: B A major complication related to intra-arterial blood pressure monitoring is hemorrhage from the insertion site. Since these vital signs are out of the normal range, are a change, and are consistent with blood loss, the nurse should assess the client for any bleeding associated with the arterial line. The nurse should document the findings after a full assessment. The client may or may not need pain medication and rest; the nurse first needs to rule out any emergent bleeding.

7. After administering newly prescribed captopril (Capoten) to a client with heart failure, the nurse implements interventions to decrease complications. Which priority intervention should the nurse implement for this client? a. Provide food to decrease nausea and aid in absorption. b. Instruct the client to ask for assistance when rising from bed. c. Collaborate with unlicensed assistive personnel to bathe the client. d. Monitor potassium levels and check for symptoms of hypokalemia.
ANS: B Administration of the first dose of angiotensin-converting enzyme (ACE) inhibitors is often associated with hypotension, usually termed first-dose effect. The nurse should instruct the client to seek assistance before arising from bed to prevent injury from postural hypotension. ACE inhibitors do not need to be taken with food. Collaboration with unlicensed assistive personnel to provide hygiene is not a priority. The client should be encouraged to complete activities of daily living as independently as possible. The nurse should monitor for hyperkalemia, not hypokalemia, especially if the client has renal insufficiency secondary to heart failure.

2. A client received tissue plasminogen activator (t-PA) after a myocardial infarction and now is on an intravenous infusion of heparin. The client's spouse asks why the client needs this medication. What response by the nurse is best? a. "The t-PA didn't dissolve the entire coronary clot." b. "The heparin keeps that artery from getting blocked again." c. "Heparin keeps the blood as thin as possible for a longer time." d. "The heparin prevents a stroke from occurring as the t-PA wears off."
ANS: B After the original intracoronary clot has dissolved, large amounts of thrombin are released into the bloodstream, increasing the chance of the vessel reoccluding. The other statements are not accurate. Heparin is not a "blood thinner," although laypeople may refer to it as such.

5. A nurse evaluates prescriptions for a client with chronic atrial fibrillation. Which medication should the nurse expect to find on this client's medication administration record to prevent a common complication of this condition? a. Sotalol (Betapace) b. Warfarin (Coumadin) c. Atropine (Sal-Tropine) d. Lidocaine (Xylocaine)
ANS: B Atrial fibrillation puts clients at risk for developing emboli. Clients at risk for emboli are treated with anticoagulants, such as heparin, enoxaparin, or warfarin. Sotalol, atropine, and lidocaine are not appropriate for this complication.

2. A nurse cares for a client who has a heart rate averaging 56 beats/min with no adverse symptoms. Which activity modification should the nurse suggest to avoid further slowing of the heart rate? a. "Make certain that your bath water is warm." b. "Avoid straining while having a bowel movement." c. "Limit your intake of caffeinated drinks to one a day." d. "Avoid strenuous exercise such as running."
ANS: B Bearing down strenuously during a bowel movement is one type of Valsalva maneuver, which stimulates the vagus nerve and results in slowing of the heart rate. Such a response is not desirable in a person who has bradycardia. The other instructions are not appropriate for this condition. DIF: Applying/Application REF: 663 KEY: Functional ability MSC: Integrated Process: Nursing Process: Implementation NOT: Client Needs Category: Physiological Integrity: Basic Care and Comfort
14. After teaching a client who is being discharged home after mitral valve replacement surgery, the nurse assesses the client's understanding. Which client statement indicates a need for additional teaching? a. "I'll be able to carry heavy loads after 6 months of rest." b. "I will have my teeth cleaned by my dentist in 2 weeks." c. "I must avoid eating foods high in vitamin K, like spinach." d. "I must use an electric razor instead of a straight razor to shave."
ANS: B Clients who have defective or repaired valves are at high risk for endocarditis. The client who has had valve surgery should avoid dental procedures for 6 months because of the risk for endocarditis. When undergoing a mitral valve replacement surgery, the client needs to be placed on anticoagulant therapy to prevent vegetation forming on the new valve. Clients on anticoagulant therapy should be instructed on bleeding precautions, including using an electric razor. If the client is prescribed warfarin, the client should avoid foods high in vitamin K. Clients recovering from open heart valve replacements should not carry anything heavy for 6 months while the chest incision and muscle heal.

4. A nurse assesses a client with atrial fibrillation. Which manifestation should alert the nurse to the possibility of a serious complication from this condition? a. Sinus tachycardia b. Speech alterations c. Fatigue d. Dyspnea with activity
ANS: B Clients with atrial fibrillation are at risk for embolic stroke. Evidence of embolic events includes changes in mentation, speech, sensory function, and motor function. Clients with atrial fibrillation often have a rapid ventricular response as a result. Fatigue is a nonspecific complaint. Clients with atrial fibrillation often have dyspnea as a result of the decreased cardiac output caused by the rhythm disturbance.

12. A nurse assists with the cardioversion of a client experiencing acute atrial fibrillation. Which action should the nurse take prior to the initiation of cardioversion? a. Administer intravenous adenosine. b. Turn off oxygen therapy. c. Ensure a tongue blade is available. d. Position the client on the left side.
ANS: B For safety during cardioversion, the nurse should turn off any oxygen therapy to prevent fire. The other interventions are not appropriate for a cardioversion. The client should be placed in a supine position.

14. A nurse is in charge of the coronary intensive care unit. Which client should the nurse see first? a. Client on a nitroglycerin infusion at 5 mcg/min, not titrated in the last 4 hours b. Client who is 1 day post coronary artery bypass graft, blood pressure 180/100 mm Hg c. Client who is 1 day post percutaneous coronary intervention, going home this morning d. Client who is 2 days post coronary artery bypass graft, became dizzy this a.m. while walking
ANS: B Hypertension after coronary artery bypass graft surgery can be dangerous because it puts too much pressure on the suture lines and can cause bleeding. The charge nurse should see this client first. The client who became dizzy earlier should be seen next. The client on the nitroglycerin drip is stable. The client going home can wait until the other clients are cared for.

6. A client has hemodynamic monitoring after a myocardial infarction. What safety precaution does the nurse implement for this client? a. Document pulmonary artery wedge pressure (PAWP) readings and assess their trends. b. Ensure the balloon does not remain wedged. c. Keep the client on strict NPO status. d. Maintain the client in a semi-Fowler's position.
ANS: B If the balloon remains inflated, it can cause pulmonary infarction or rupture. The nurse should ensure the balloon remains deflated between PAWP readings. Documenting PAWP readings and assessing trends is an important nursing action related to hemodynamic monitoring, but is not specifically related to safety. The client does not have to be NPO while undergoing hemodynamic monitoring. Positioning may or may not affect readings.

8. A nurse cares for a client with an intravenous temporary pacemaker for bradycardia. The nurse observes the presence of a pacing spike but no QRS complex on the client's electrocardiogram. Which action should the nurse take next? a. Administer intravenous diltiazem (Cardizem). b. Assess vital signs and level of consciousness. c. Administer sublingual nitroglycerin. d. Assess capillary refill and temperature.
ANS: B In temporary pacing, the wires are threaded onto the epicardial surface of the heart and exit through the chest wall. The pacemaker spike should be followed immediately by a QRS complex. Pacing spikes seen without subsequent QRS complexes imply loss of capture. If there is no capture, then there is no ventricular depolarization and contraction. The nurse should assess for cardiac output via vital signs and level of consciousness. The other interventions would not determine if the client is tolerating the loss of capture.

15. A client with coronary artery disease (CAD) asks the nurse about taking fish oil supplements. What response by the nurse is best? a. "Fish oil is contraindicated with most drugs for CAD." b. "The best source is fish, but pills have benefits too." c. "There is no evidence to support fish oil use with CAD." d. "You can reverse CAD totally with diet and supplements."
ANS: B Omega-3 fatty acids have shown benefit in reducing lipid levels, in reducing the incidence of sudden cardiac death, and for stabilizing atherosclerotic plaque. The best source is fish three times a week or some fish oil supplements. The other options are not accurate.

3. A nurse assesses a client admitted to the cardiac unit. Which statement by the client alerts the nurse to the possibility of right-sided heart failure? a. "I sleep with four pillows at night." b. "My shoes fit really tight lately." c. "I wake up coughing every night." d. "I have trouble catching my breath."
ANS: B Signs of systemic congestion occur with right-sided heart failure. Fluid is retained, pressure builds in the venous system, and peripheral edema develops. Left-sided heart failure symptoms include respiratory symptoms. Orthopnea, coughing, and difficulty breathing all could be results of left-sided heart failure.

13. A nurse cares for a client recovering from prosthetic valve replacement surgery. The client asks, "Why will I need to take anticoagulants for the rest of my life?" How should the nurse respond? a. "The prosthetic valve places you at greater risk for a heart attack." b. "Blood clots form more easily in artificial replacement valves." c. "The vein taken from your leg reduces circulation in the leg." d. "The surgery left a lot of small clots in your heart and lungs."
ANS: B Synthetic valve prostheses and scar tissue provide surfaces on which platelets can aggregate easily and initiate the formation of blood clots. The other responses are inaccurate.

10. After teaching a client who has an implantable cardioverter-defibrillator (ICD), a nurse assesses the client's understanding. Which statement by the client indicates a correct understanding of the teaching? a. "I should wear a snug-fitting shirt over the ICD." b. "I will avoid sources of strong electromagnetic fields." c. "I should participate in a strenuous exercise program." d. "Now I can discontinue my antidysrhythmic medication."
ANS: B The client being discharged with an ICD is instructed to avoid strong sources of electromagnetic fields. Clients should avoid tight clothing, which could cause irritation over the ICD generator. The client should be encouraged to exercise but should not engage in strenuous activities that cause the heart rate to meet or exceed the ICD cutoff point because the ICD can discharge inappropriately. The client should continue all prescribed medications.

3. A client is in the hospital after suffering a myocardial infarction and has bathroom privileges. The nurse assists the client to the bathroom and notes the client's O2 saturation to be 95%, pulse 88 beats/min, and respiratory rate 16 breaths/min after returning to bed. What action by the nurse is best? a. Administer oxygen at 2 L/min. b. Allow continued bathroom privileges. c. Obtain a bedside commode. d. Suggest the client use a bedpan.
ANS: B This client's physiologic parameters did not exceed normal during and after activity, so it is safe for the client to continue using the bathroom. There is no indication that the client needs oxygen, a commode, or a bedpan.

Assess the client's pupillary responses. b. Request a neurologic consultation. c. Stop the infusion and call the provider. d. Take and document a full set of vital signs.
ANS: C A change in neurologic status in a client receiving t-PA could indicate intracranial hemorrhage. The nurse should stop the infusion and notify the provider immediately. A full assessment, including pupillary responses and vital signs, occurs next. The nurse may or may not need to call a neurologist.

7. A telemetry nurse assesses a client with third-degree heart block who has wide QRS complexes and a heart rate of 35 beats/min on the cardiac monitor. Which assessment should the nurse complete next? a. Pulmonary auscultation b. Pulse strength and amplitude c. Level of consciousness d. Mobility and gait stability
ANS: C A heart rate of 40 beats/min or less with widened QRS complexes could have hemodynamic consequences. The client is at risk for inadequate cerebral perfusion. The nurse should assess for level of consciousness, light-headedness, confusion, syncope, and seizure activity. Although the other assessments should be completed, the client's level of consciousness is the priority.

10. A client in the cardiac stepdown unit reports severe, crushing chest pain accompanied by nausea and vomiting. What action by the nurse takes priority? a. Administer an aspirin. b. Call for an electrocardiogram (ECG). c. Maintain airway patency. d. Notify the provider.
ANS: C Airway always is the priority. The other actions are important in this situation as well, but the nurse should stay with the client and ensure the airway remains patent (especially if vomiting occurs) while another person calls the provider (or Rapid Response Team) and facilitates getting an ECG done. Aspirin will probably be administered, depending on the provider's prescription and the client's current medications.

Provide the client with a sleeping pill to stimulate rest. c. Schedule periods of exercise and rest during the day. d. Ask unlicensed assistive personnel to help bathe the client.
ANS: C Clients who have atrial fibrillation are at risk for decreased cardiac output and fatigue when completing activities of daily living. The nurse should schedule periods of exercise and rest during the day to decrease fatigue. The other interventions will not assist the client with self-care activities.

16. The nurse asks a client who has experienced ventricular dysrhythmias about substance abuse. The client asks, "Why do you want to know if I use cocaine?" How should the nurse respond? a. "Substance abuse puts clients at risk for many health issues." b. "The hospital requires that I ask you about cocaine use." c. "Clients who use cocaine are at risk for fatal dysrhythmias." d. "We can provide services for cessation of substance abuse."
ANS: C Clients who use cocaine or illicit inhalants are particularly at risk for potentially fatal dysrhythmias. The other responses do not adequately address the client's question.

2. A nurse assesses a client in an outpatient clinic. Which statement alerts the nurse to the possibility of left-sided heart failure? a. "I have been drinking more water than usual." b. "I am awakened by the need to urinate at night." c. "I must stop halfway up the stairs to catch my breath." d. "I have experienced blurred vision on several occasions."
ANS: C Clients with left-sided heart failure report weakness or fatigue while performing normal activities of daily living, as well as difficulty breathing, or "catching their breath." This occurs as fluid moves into the alveoli. Nocturia is often seen with right-sided heart failure. Thirst and blurred vision are not related to heart failure.

8. A nurse assesses a client after administering isosorbide mononitrate (Imdur). The client reports a headache. Which action should the nurse take? a. Initiate oxygen therapy. b. Hold the next dose of Imdur. c. Instruct the client to drink water. d. Administer PRN acetaminophen.
ANS: D The vasodilating effects of isosorbide mononitrate frequently cause clients to have headaches during the initial period of therapy. Clients should be told about this side effect and encouraged to take the medication with food. Some clients obtain relief with mild analgesics, such as acetaminophen. The client's headache is not related to hypoxia or dehydration; therefore, these interventions would not help. The client needs to take the medication as prescribed to prevent angina; the medication should not be held.

"Avoid drinking more than 3 quarts of liquids each day." b. "Eat six small meals daily instead of three larger meals." c. "When you feel short of breath, take an additional diuretic." d. "Weigh yourself daily while wearing the same amount of clothing."
ANS: D Clients with heart failure are instructed to weigh themselves daily to detect worsening heart failure early, and thus avoid complications. Other signs of worsening heart failure include increasing dyspnea, exercise intolerance, cold symptoms, and nocturia. Fluid overload increases symptoms of heart failure. The client should be taught to eat a heart-healthy diet, balance intake and output to prevent dehydration and overload, and take medications as prescribed. The most important discharge teaching is daily weights as this provides the best data related to fluid retention.

9. A nurse teaches a client who is prescribed digoxin (Lanoxin) therapy. Which statement should the nurse include in this client's teaching? a. "Avoid taking aspirin or aspirin-containing products." b. "Increase your intake of foods that are high in potassium." c. "Hold this medication if your pulse rate is below 80 beats/min." d. "Do not take this medication within 1 hour of taking an antacid."
ANS: D Gastrointestinal absorption of digoxin is erratic. Many medications, especially antacids, interfere with its absorption. Clients are taught to hold their digoxin for bradycardia; a heart rate of 80 beats/min is too high for this cutoff. Potassium and aspirin have no impact on digoxin absorption, nor do these statements decrease complications of digoxin therapy.

1. A nurse assesses a client's electrocardiograph tracing and observes that not all QRS complexes are preceded by a P wave. How should the nurse interpret this observation? a. The client has hyperkalemia causing irregular QRS complexes. b. Ventricular tachycardia is overriding the normal atrial rhythm. c. The client's chest leads are not making sufficient contact with the skin. d. Ventricular and atrial depolarizations are initiated from different sites.
ANS: D Normal rhythm shows one P wave preceding each QRS complex, indicating that all depolarization is initiated at the sinoatrial node. QRS complexes without a P wave indicate a different source of initiation of depolarization. This finding on an electrocardiograph tracing is not an indication of hyperkalemia, ventricular tachycardia, or disconnection of leads.

5. A client undergoing hemodynamic monitoring after a myocardial infarction has a right atrial pressure of 0.5 mm Hg. What action by the nurse is most appropriate? a. Level the transducer at the phlebostatic axis. b. Lay the client in the supine position. c. Prepare to administer diuretics. d. Prepare to administer a fluid bolus.
ANS: D Normal right atrial pressures are from 1 to 8 mm Hg. Lower pressures usually indicate hypovolemia, so the nurse should prepare to administer a fluid bolus. The transducer should remain leveled at the phlebostatic axis. Positioning may or may not influence readings. Diuretics would be contraindicated.

Ask the family members to wait in the waiting area. b. Inform the client that this behavior is unacceptable. c. Stay out of the room to decrease the client's stress levels. d. Tell the client that anxiety is common and that you can help.
ANS: D Preoperative fear and anxiety are common prior to cardiac surgery, especially in emergent situations. The client is exhibiting anxiety, and the nurse should reassure the client that fear is common and offer to help. The other actions will not reduce the client's anxiety.

9. A nurse prepares to defibrillate a client who is in ventricular fibrillation. Which priority intervention should the nurse perform prior to defibrillating this client? a. Make sure the defibrillator is set to the synchronous mode. b. Administer 1 mg of intravenous epinephrine. c. Test the equipment by delivering a smaller shock at 100 joules. d. Ensure that everyone is clear of contact with the client and the bed.
ANS: D To avoid injury, the rescuer commands that all personnel clear contact with the client or the bed and ensures their compliance before delivery of the shock. A precordial thump can be delivered when no defibrillator is available. Defibrillation is done in asynchronous mode. Equipment should not be tested before a client is defibrillated because this is an emergency procedure; equipment should be checked on a routine basis. Epinephrine should be administered after defibrillation.

The nurse is caring for a group of clients who have sustained myocardial infarction (MI). The nurse observes the client with which type of MI most carefully for the development of left ventricular heart failure? Inferior wall Anterior wall Lateral wall Posterior wall
Anterior wall Due to the large size of the anterior wall, the amount of tissue infarction may be large enough to decrease the force of contraction, leading to heart failure. The client with an inferior wall MI is more likely to develop right ventricular heart failure. Clients with obstruction of the circumflex artery may experience a lateral wall MI and sinus dysrhythmias or a posterior wall MI and sinus dysrhythmias.
An older adult client, 4 hours after coronary artery bypass graft (CABG), has a blood pressure of 80/50 mm Hg. What action does the nurse take? No action is required; low blood pressure is normal for older adults. No action is required for postsurgical CABG clients. Assess pulmonary artery wedge pressure (PAWP). Give ordered loop diuretics.
Assess pulmonary artery wedge pressure (PAWP). Decreased preload as exhibited by decreased PAWP could indicate hypovolemia secondary to hemorrhage or vasodilation; hypotension could cause the graft to collapse. Low blood pressure is not normal in older adults or postoperative clients. The cause of hypotension must be found and treated; further action is needed to determine additional interventions. Hypotension could be caused by hypovolemia; giving loop diuretics increases hypovolemia.
14. A nurse teaches a client with diabetes mellitus and a body mass index of 42 who is at high risk for coronary artery disease. Which statement related to nutrition should the nurse include in this clients teaching? a. The best way to lose weight is a high-protein, low-carbohydrate diet. b. You should balance weight loss with consuming necessary nutrients. c. A nutritionist will provide you with information about your new diet. d. If you exercise more frequently, you wont need to change your diet.
B Clients at risk for cardiovascular diseases should follow the American Heart Association guidelines to combat obesity and improve cardiac health. The nurse should encourage the client to eat vegetables, fruits, unrefined whole-grain products, and fat-free dairy products while losing weight. High-protein food items are often high in fat and calories. Although the nutritionist can assist with client education, the nurse should include nutrition education and assist the client to make healthy decisions. Exercising and eating nutrient-rich foods are both important components in reducing cardiovascular risk.
13. A nurse cares for a client who has an 80% blockage of the right coronary artery (RCA) and is scheduled for bypass surgery. Which intervention should the nurse be prepared to implement while this client waits for surgery? a. Administration of IV furosemide (Lasix) b. Initiation of an external pacemaker c. Assistance with endotracheal intubation d. Placement of central venous access
B The RCA supplies the right atrium, the right ventricle, the inferior portion of the left ventricle, and the atrioventricular (AV) node. It also supplies the sinoatrial node in 50% of people. If the client totally occludes the RCA, the AV node would not function and the client would go into heart block, so emergency pacing should be available for the client. Furosemide, intubation, and central venous access will not address the primary complication of RCA occlusion, which is AV node malfunction.
6. A nurse obtains the health history of a client who is newly admitted to the medical unit. Which statement by the client should alert the nurse to the presence of edema? a. I wake up to go to the bathroom at night. b. My shoes fit tighter by the end of the day. c. I seem to be feeling more anxious lately. d. I drink at least eight glasses of water a day.
B Weight gain can result from fluid accumulation in the interstitial spaces. This is known as edema. The nurse should note whether the client feels that his or her shoes or rings are tight, and should observe, when present, an indentation around the leg where the socks end. The other answers do not describe edema.
4. A nurse assesses an older adult client who has multiple chronic diseases. The clients heart rate is 48 beats/min. Which action should the nurse take first? a. Document the finding in the chart. b. Initiate external pacing. c. Assess the clients medications. d. Administer 1 mg of atropine.
C Pacemaker cells in the conduction system decrease in number as a person ages, resulting in bradycardia. The nurse should check the medication reconciliation for medications that might cause such a drop in heart rate, then should inform the health care provider. Documentation is important, but it is not the priority action. The heart rate is not low enough for atropine or an external pacemaker to be needed.
9. A nurse assesses a client who is recovering after a left-sided cardiac catheterization. Which assessment finding requires immediate intervention? a. Urinary output less than intake b. Bruising at the insertion site c. Slurred speech and confusion d. Discomfort in the left leg
C A left-sided cardiac catheterization specifically increases the risk for a cerebral vascular accident. A change in neurologic status needs to be acted on immediately. Discomfort and bruising are expected at the site. If intake decreases, a client can become dehydrated because of dye excretion. The second intervention would be to increase the clients fluid status. Neurologic changes would take priority.
16. A nurse cares for a client who is recovering from a myocardial infarction. The client states, I will need to stop eating so much chili to keep that indigestion pain from returning. How should the nurse respond? a. Chili is high in fat and calories; it would be a good idea to stop eating it. b. The provider has prescribed an antacid for you to take every morning. c. What do you understand about what happened to you? d. When did you start experiencing this indigestion?
C Clients who experience myocardial infarction often respond with denial, which is a defense mechanism. The nurse should ask the client what he or she thinks happened, or what the illness means to him or her. The other responses do not address the clients misconception about recent pain and the cause of that pain.
8. A nurse assesses a client 2 hours after a cardiac angiography via the left femoral artery. The nurse notes that the left pedal pulse is weak. Which action should the nurse take? a. Elevate the leg and apply a sandbag to the entrance site. b. Increase the flow rate of intravenous fluids. c. Assess the color and temperature of the left leg. d. Document the finding as left pedal pulse of +1/4.
C Loss of a pulse distal to an angiography entry site is serious, indicating a possible arterial obstruction. The pulse may be faint because of edema. The left pulse should be compared with the right, and pulses should be compared with previous assessments, especially before the procedure. Assessing color (pale, cyanosis) and temperature (cool, cold) will identify a decrease in circulation. Once all peripheral and vascular assessment data are acquired, the primary health care provider should be notified. Simply documenting the findings is inappropriate. The leg should be positioned below the level of the heart or dangling to increase blood flow to the distal portion of the leg. Increasing intravenous fluids will not address the clients problem.
3. A nurse assesses clients on a medical-surgical unit. Which client should the nurse identify as having the greatest risk for cardiovascular disease? a. An 86-year-old man with a history of asthma b. A 32-year-old Asian-American man with colorectal cancer c. A 45-year-old American Indian woman with diabetes mellitus d. A 53-year-old postmenopausal woman who is on hormone therapy
C The incidence of coronary artery disease and hypertension is higher in American Indians than in whites or Asian Americans. Diabetes mellitus increases the risk for hypertension and coronary artery disease in people o any race or ethnicity. Asthma, colorectal cancer, and hormone therapy do not increase risk for cardiovascular disease.
The nurse in the coronary care unit is caring for a group of clients who have had myocardial infarction. Which client does the nurse see first? Client with dyspnea on exertion when ambulating to the bathroom Client with third-degree heart block on the monitor Client with normal sinus rhythm and PR interval of 0.28 second Client who refuses to take heparin or nitroglycerin
Client with third-degree heart block on the monitor Third-degree heart block is a serious complication that indicates that a large portion of the left ventricle and conduction system are involved, so the client with the third-degree heart block should be seen first. Third-degree heart block usually requires pacemaker insertion. A normal rhythm with prolonged PR interval indicates first-degree heart block, which usually does not require treatment. The client with dyspnea on exertion when ambulating to the bathroom is not at immediate risk. The client's uncooperative behavior when refusing to take heparin or nitroglycerin may indicate fear or denial; he should be seen after emergency situations have been handled.
10. A nurse assesses a client who is scheduled for a cardiac catheterization. Which assessment should the nurse complete prior to this procedure? a. Clients level of anxiety b. Ability to turn self in bed c. Cardiac rhythm and heart rate d. Allergies to iodine-based agents
D Before the procedure, the nurse should ascertain whether the client has an allergy to iodine-containing preparations, such as seafood or local anesthetics. The contrast medium used during the procedure is iodine based. This allergy can cause a life-threatening reaction, so it is a high priority. Second, it is important for the nurse to assess anxiety, mobility, and baseline cardiac status.
2. A nurse assesses a client after administering a prescribed beta blocker. Which assessment should the nurse expect to find? a. Blood pressure increased from 98/42 mm Hg to 132/60 mm Hg b. Respiratory rate decreased from 25 breaths/min to 14 breaths/min c. Oxygen saturation increased from 88% to 96% d. Pulse decreased from 100 beats/min to 80 beats/min
D Beta blockers block the stimulation of beta1-adrenergic receptors. They block the sympathetic (fight-or-flight) response and decrease the heart rate (HR). The beta blocker will decrease HR and blood pressure, increasing ventricular filling time. It usually does not have effects on beta2-adrenergic receptor sites. Cardiac output will drop because of decreased HR.
Prompt pain management with myocardial infarction is essential for which reason? The discomfort will increase client anxiety and reduce coping. Pain relief improves oxygen supply and decreases oxygen demand. Relief of pain indicates that the MI is resolving. Pain medication should not be used until a definitive diagnosis has been established.
Pain relief improves oxygen supply and decreases oxygen demand. The focus of pain relief is on reducing myocardial oxygen demand. Chest discomfort will increase anxiety, but it may not affect coping. Relief of pain is secondary to the use of opiates or indicates that the tissue infarction is complete. Although it used to be true that pain medication was not to be used for undiagnosed abdominal pain, this does not relate to MI.
The nurse is caring for a client in phase 1 cardiac rehabilitation. Which activity does the nurse suggest? The need to increase activities slowly at home Planning and participating in a walking program Placing a chair in the shower for independent hygiene Consultation with social worker for disability planning
Placing a chair in the shower for independent hygiene Phase 1 begins with the acute illness and ends with discharge from the hospital; it focuses on promoting rest and allowing clients to improve their activities of daily living based on their abilities. Phase 2 begins after discharge and continues through convalescence at home, including consultation with a social worker for long-term planning; it consists of achieving and maintaining a vital and productive life while remaining within the limits of the heart's ability to respond to increases in activity and stress. Phase 3 refers to long-term conditioning, such as a walking program.
The nurse is assessing a client with chest pain to evaluate whether the client is suffering from angina or myocardial infarction (MI). Which symptom is indicative of an MI? Chest pain brought on by exertion or stress Substernal chest discomfort occurring at rest Substernal chest discomfort relieved by nitroglycerin or rest Substernal chest pressure relieved only by opioids
Substernal chest pressure relieved only by opioids Substernal chest pressure relieved only by opioids is typically indicative of MI. Substernal chest discomfort that occurs at rest is not necessarily indicative of MI; it could be a sign of unstable angina. Both chest pain brought on by exertion or stress and substernal chest discomfort relieved by nitroglycerin or rest are indicative of angina.
A client with unstable angina has received education about acute coronary syndrome. Which statement indicates that the client has understood the teaching? a. "This is a big warning; I must modify my lifestyle or risk having a heart attack in the next year." b. "Angina is just a temporary interruption of blood flow to my heart." c. "I need to tell my wife I've had a heart attack." d. "Because this was temporary, I will not need to take any medications for my heart."
a. "This is a big warning; I must modify my lifestyle or risk having a heart attack in the next year." Among people who have unstable angina, 10% to 30% have a myocardial infarction within 1 year. Although anginal pain is temporary, it reflects underlying coronary artery disease (CAD), which requires attention, including lifestyle modifications. Unstable angina reflects tissue ischemia, but infarction represents tissue necrosis. Clients with underlying CAD may need medications such as aspirin, lipid-lowering agents, anti-anginals, or antihypertensives.

After thrombolytic therapy, the nurse working in the cardiac catheterization laboratory would be alarmed to notice which sign? a. A 1-inch backup of blood in the IV tubing b. Facial drooping c. Partial thromboplastin time (PTT) 68 seconds d. Report of chest pressure during dye injection
b. Facial drooping During and after thrombolytic administration, the nurse observes for any indications of bleeding, including changes in neurologic status, which may indicate intracranial bleeding. A 1-inch backup of blood in the IV tubing may be related to IV positioning. If heparin is used, PTT reflects a therapeutic value. Reports of chest pressure during dye injection or stent deployment are considered an expected result of the procedure.
Prompt pain management with myocardial infarction is essential for which reason? a. The discomfort will increase client anxiety and reduce coping. b. Pain relief improves oxygen supply and decreases oxygen demand. c. Relief of pain indicates that the MI is resolving. d. Pain medication should not be used until a definitive diagnosis has been established.

A client undergoing coronary artery bypass grafting asks why the surgeon has chosen to use the internal mammary artery for the surgery. Which response by the nurse is correct? a. "This way you will not need to have a leg incision." b. "The surgeon prefers this approach because it is easier." c. "These arteries remain open longer." d. "The surgeon has chosen this approach because of your age."
c. "These arteries remain open longer." Mammary arteries remain patent much longer than other grafts. Although no leg incision will be made with this approach, veins from the legs do not remain patent as long as the mammary artery graft does. Long-term patency, not ease of the procedure, is the primary concern. Age is not a determining factor in selection of these grafts.
The nurse is teaching a group of teens about prevention of heart disease. Which point should the nurse emphasize? a. Reduce abdominal fat. b. Avoid stress. c. Do not smoke or chew tobacco. d. Avoid alcoholic beverages.
c. Do not smoke or chew tobacco. Tobacco exposure, including secondhand smoke, reduces coronary blood flow; causes vasoconstriction, endothelial dysfunction, and thickening of the vessel walls; increases carbon monoxide; and decreases oxygen. Because it is highly addicting, beginning smoking in the teen years may lead to decades of exposure. Teens are not likely to experience metabolic syndrome from obesity, but are very likely to use tobacco. Avoiding stress is a less modifiable risk factor, which is less likely to cause heart disease in teens. The risk of smoking outweighs the risk of alcohol use.

The nurse is caring for a client in phase 1 cardiac rehabilitation. Which activity does the nurse suggest? a. The need to increase activities slowly at home b. Planning and participating in a walking program c. Placing a chair in the shower for independent hygiene d. Consultation with social worker for disability planning
c. Placing a chair in the shower for independent hygiene Phase 1 begins with the acute illness and ends with discharge from the hospital; it focuses on promoting rest and allowing clients to improve their activities of daily living based on their abilities. Phase 2 begins after discharge and continues through convalescence at home, including consultation with a social worker for long-term planning; it consists of achieving and maintaining a vital and productive life while remaining within the limits of the heart's ability to respond to increases in activity and stress. Phase 3 refers to long-term conditioning, such as a walking program.
During discharge planning after admission for a myocardial infarction, the client says, "I won't be able to increase my activity level. I live in an apartment, and there is no place to walk." What is the nurse's best response? a. "You are right. Work on your diet then." b. "You must find someplace to walk." c. "Walk around the edge of your apartment complex." d. "Where might you be able to walk?"
d. "Where might you be able to walk?" Asking the client where he or she might be able to walk calls for cooperation and participation from the client; increased activity is imperative for this client. Telling the client to work on diet is an inappropriate response. Telling the client to find someplace to walk is too demanding to be therapeutic. Telling the client to walk around the apartment complex is domineering and will not likely achieve cooperation from the client.
