When planning emergent care for a patient with a suspected MI, the nurse will anticipate administration of: A. Oxygen, nitroglycerin, aspirin, and morphine. B. Oxygen, furosemide (Lasix), nitroglycerin, and meperidine. C. Aspirin, nitroprusside (Nipride), dopamine (Intropin), and oxygen. D. Nitroglycerin, lorazepam (Ativan), oxygen, and warfarin (Coumadin).

A. The American Heart Association's guidelines for emergency care of the patient with chest pain include the administration of oxygen, nitroglycerin, aspirin, and morphine. These interventions serve to relieve chest pain, improve oxygenation, decrease myocardial workload, and prevent further platelet aggregation.

The client is one 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 morphine2. Assess the client's chest dressing and vital signs3. Encourage the client to turn from side to side4. Check the client's telemetry monitor

2. Assess the client's chest dressing and vital signs

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 642. The client's calcium level is elevated3. The client's telemetry shows occasional PVCs4. The client's blood pressure is 90/62

4. The client's blood pressure is low, and a calcium channel blocker could cause the blood pressure to bottom out.

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.

ANS: 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.

8. A nurse assesses a client who is recovering from a heart transplant. Which assessment findings should alert the nurse to the possibility of heart transplant rejection? (Select all that apply.) a. Shortness of breath b. Abdominal bloating c. New-onset bradycardia d. Increased ejection fraction e. Hypertension

ANS: A, B, C Clinical manifestations of heart transplant rejection include shortness of breath, fatigue, fluid gain, abdominal bloating, new-onset bradycardia, hypotension, atrial fibrillation or flutter, decreased activity tolerance, and decreased ejection fraction.

3. A nurse assesses clients on a cardiac unit. Which clients should the nurse identify as at greatest risk for the development of acute pericarditis? (Select all that apply.) a. A 36-year-old woman with systemic lupus erythematosus (SLE) b. A 42-year-old man recovering from coronary artery bypass graft surgery c. A 59-year-old woman recovering from a hysterectomy d. An 80-year-old man with a bacterial infection of the respiratory tract e. An 88-year-old woman with a stage III sacral ulcer

ANS: A, B, D Acute pericarditis is most commonly associated acute exacerbations of systemic connective tissue disease, including SLE; with Dresslers syndrome, or inflammation of the cardiac sac after cardiac surgery or a myocardial infarction; and with infective organisms, including bacterial, viral, and fungal infections. Abdominal and reproductive surgeries and pressure ulcers do not increase clients risk for acute pericarditis.

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 assesses a client with mitral valve stenosis. What clinical manifestation should alert the nurse to the possibility that the clients stenosis has progressed? a. Oxygen saturation of 92% b. Dyspnea on exertion c. Muted systolic murmur d. Upper extremity weakness

ANS: B Dyspnea on exertion develops as the mitral valvular orifice narrows and pressure in the lungs increases. The other manifestations do not relate to the progression of mitral valve stenosis.

6. A nurse administers prescribed adenosine (Adenocard) to a client. Which response should the nurse assess for as the expected therapeutic response? a. Decreased intraocular pressure b. Increased heart rate c. Short period of asystole d. Hypertensive crisis

ANS: C Clients usually respond to adenosine with a short period of asystole, bradycardia, hypotension, dyspnea, and chest pain. Adenosine has no conclusive impact on intraocular pressure.

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.

what is the expected EKG pattern for a pt when a thrombus in a coronary artery lodges permanently in the vessel and the infarction extends through the myocardium from the endocardium to the epicardium? A. prolonged QT interval B. ST elevation C. ST depression D. non ST elevation

B. ST elevation

cardiac cells can withstand ischemic conditions and still return to a viable state for ______ minutes. A. 10 B. 15 C. 20 D. 25

C. 20

3 . A nurse is teaching a client w ith premature ectopic beats. W hich education should the nurse include in this clients teaching? (Select all that apply .) a. Smoking cessation b . Stress reduction and management c. Avoiding vagal stimulation d . Adverse effects of medications e. Foods high in potassium

ANS : A , B , D A client who has premature beats or ectopic rhythms should be taught to stop smoking , manage stress, take medications as prescribed , and report adverse effects of medications. C lients w ith premature beats are not a t risk for vasovagal attacks or potassium imbalances.

9. A nurse assesses a client who is diagnosed with infective endocarditis. Which assessment findings should the nurse expect? (Select all that apply .) a. W eight gain b . N ight sweats c. Cardiac murmur d . Abdom inal bloating e. O slers nodes

ANS : B , C , E C linical manifestations of infective endocarditis include fever w ith chills, night sweats, malaise and fatigue , anorexia and weight loss, cardiac murmur, and O slers nodes on palms of the hands and soles of the feet. Abdom inal bloating is a manifestation of heart transplantation rejection.

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

ANS: 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

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 clients 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.

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 clients 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 clients integumentary system. Monitoring pedal pulses and vital signs give indications as to how well the drug is working.

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.

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.

ANS: 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.

2. A nurse teaches a client with a new permanent pacemaker. Which instructions should the nurse include in this clients teaching? (Select all that apply.) a. Until your incision is healed, do not submerge your pacemaker. Only take showers. b. Report any pulse rates lower than your pacemaker settings. c. 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.

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.

18. A nurse teaches a client recovering from a heart transplant who is prescribed cyclosporine (Sandimmune). Which statement should the nurse include in this clients discharge teaching? a. Use a soft-bristled toothbrush and avoid flossing. b. Avoid large crowds and people who are sick. c. Change positions slowly to avoid hypotension. d. Check your heart rate before taking the medication.

ANS: B These agents cause immune suppression, leaving the client more vulnerable to infection. The medication does not place the client at risk for bleeding, orthostatic hypotension, or a change in heart rate.

16. A nurse assesses a client with pericarditis. Which assessment finding should the nurse expect to find? a. Heart rate that speeds up and slows down b. Friction rub at the left lower sternal border c. Presence of a regular gallop rhythm d. Coarse crackles in bilateral lung bases

ANS: B The client with pericarditis may present with a pericardial friction rub at the left lower sternal border. This sound is the result of friction from inflamed pericardial layers when they rub together. The other assessments are not related.

2. A client received tissue plasminogen activator (t-PA) after a myocardial infarction and now is on an intravenous infusion of heparin. The clients spouse asks why the client needs this medication. What response by the nurse is best? a. The t-PA didnt 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.

24. A nurse assesses a client who has mitral valve regurgitation. For which cardiac dysrhythmia should the nurse assess? a. Preventricular contractions b. Atrial fibrillation c. Symptomatic bradycardia d. Sinus tachycardia

ANS: B Atrial fibrillation is a clinical manifestation of mitral valve regurgitation and stenosis. Preventricular contractions and bradycardia are not associated with valvular problems. These are usually identified in clients with electrolyte imbalances, myocardial infarction, and sinus node problems. Sinus tachycardia is a manifestation of aortic regurgitation due to a decrease in cardiac output.

3. A nurse is assessing clients on a medical-surgical unit. Which client should the nurse identify as being at greatest risk for atrial fibrillation? a. A 45-year-old who takes an aspirin daily b. A 50-year-old who is post coronary artery bypass graft surgery c. A 78-year-old who had a carotid endarterectomy d. An 80-year-old with chronic obstructive pulmonary disease

ANS: B Atrial fibrillation occurs commonly in clients with cardiac disease and is a common occurrence after coronary artery bypass graft surgery. The other conditions do not place these clients at higher risk for atrial fibrillation

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.

14. After teaching a client who is being discharged home after mitral valve replacement surgery, the nurse assesses the clients understanding. Which client statement indicates a need for additional teaching? a. Ill 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.

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.

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 clients 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

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.

16. A client has presented to the emergency department with an acute myocardial infarction (MI). What action by the nurse is best to meet The Joint Commissions Core Measures outcomes? a. Obtain an electrocardiogram (ECG) now and in the morning. b. Give the client an aspirin. c. Notify the Rapid Response Team. d. Prepare to administer thrombolytics.

ANS: B The Joint Commissions Core Measures set for acute MI require that aspirin is administered when a client with MI presents to the emergency department or when an MI occurs in the hospital. A rapid ECG is vital, but getting another one in the morning is not part of the Core Measures set. The Rapid Response Team is not needed if an emergency department provider is available. Thrombolytics may or may not be needed

10. After teaching a client who has an implantable cardioverter-defibrillator (ICD), a nurse assesses the clients 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.

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

ANS: 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.

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

ANS: 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.

ANS: 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 Hgb. 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

ANS: 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.

3. A nursing student studying acute coronary syndromes learns that the pain of a myocardial infarction (MI) differs from stable angina in what ways? (Select all that apply.) a. Accompanied by shortness of breath b. Feelings of fear or anxiety c. Lasts less than 15 minutes d. No relief from taking nitroglycerin e. Pain occurs without known cause

ANS: B, D, E The pain from an MI is often accompanied by shortness of breath and fear or anxiety. It lasts longer than 15 minutes and is not relieved by nitroglycerin. It occurs without a known cause such as exertion.

24. The provider requests the nurse start an infusion of an inotropic agent on a client. How does the nurse explain the action of these drugs to the client and spouse? a. It constricts vessels, improving blood flow. b. It dilates vessels, which lessens the work of the heart. c. It increases the force of the hearts contractions. d. It slows the heart rate down for better filling.

ANS: C A positive inotrope is a medication that increases the strength of the hearts contractions. The other options are not correct.

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

ANS: 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.

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 clients question.

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 clients question.

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.

ANS: 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

ANS: 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 of any race or ethnicity. Asthma, colorectal cancer, and hormone therapy do not increase risk for cardiovascular disease.

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

ANS: 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.

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 immediately2. Elevate the head of the client's bed3. Document this as a normal and expected finding4. Administer morphine intravenously

1. An S3 indicates left ventricular failure and should be reported to the healthcare provider. It is a potentially life threatening complication of a myocardial infarction

The client comes into the emergency department saying, "I am having a heart attack" Which question is most pertinent when assessing the client?1. "Can you describe the chest pain"2. "What were you doing when the pain started"3. "Did you have a high-fat meal today"4. "Does the pain get worse when you lie down"

1. The chest pain for MI is usually described as an elephant sitting on the chest or a belt squeezing the substernal midchest, often radiating to the jaw or left arm.

The nurse is transcribing the doctor's orders for a client with congestive heart failure. The order reads 2.5 mg of Lanoxin daily. Which action should the nurse implement?1. Discuss the order with the health-care provider2. Take the client's apical pulse rate before administering3. Check the client's potassium level before giving the medication4. Determine if a digoxin level has been drawn

1. This dose is 10 times the normal dose for a client with CHF. This dose is potentially lethal.

The client is admitted to the emergency department, and the nurse suspects a cardiac problem. Which assessment interventions should the nurse implement? Select All that Apply1. Obtain a midstream urine specimen2. Attach telemetry monitor to the client3. Start a saline lock in the right arm4. Draw a baseline metabolic panel (BMP)5. Request an order for a STAT 12-lead ECG

2. Anytime a nurse suspects cardiac problems, the electrical conductivity of the heart should be assessed. 3. Emergency medications for heart problems are primarily administered intravenously, so starting a saline lock in the right arm is appropriate. 5. A 12-lead ECG evaluates the electrical conductivity of the heart from all planes.

The nurse is caring for a client diagnosed with a myocardial infarction who is experiencing chest pain. Which interventions should the nurse implement first? Select All that Apply1. Administer morphine sulfate Intramuscularly2. Administer an aspirin orally3. Apply oxygen via nasal cannula4. Place the client in a supine position5. Administer nitroglycerin subcutaneously

2. Aspirin is an antiplatelet medication and should be administered orally.3. Oxygen will help decrease myocardial ischeima, thereby decreasing pain

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 pyrosis2. Diaphoresis and cool clammy skin3. Intermittent claudication and paloor4. Jugular vein distention and dependent edema

2. Diaphoresis 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

After thrombolytic therapy, the nurse working in the cardiac catheterization laboratory would be alarmed to notice which sign?1. 1 inch backup of blood in the IV tubing2. Facial drooping3. Partial thromboplastin time (PTT) 68 seconds4. Report of chest pressure during dye injection

2. During and after thrombolytic administration, the nurse observes for any indications of bleeding, including changes in neurologic status, which may indicate intracranial bleeding.

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?1. Inferior wall2. Anterior wall3. Lateral wall4. Posterior wall

2. Owing 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. with the inferior wall, the client is more likely to develop right ventricular MI. regarding clients with obstruction of the circumflex artery may experience a lateral wall or posterior wall MI and sinus dysrhythmias.

Which intervention should the nurse implement with the client diagnosed with dilated cardiomyopathy?1. Keep the client in the supine position with legs elevated2. Discuss a heart transplant, which is a definitive treatment3. Prepare the client for coronary artery bypass graft4. Teach the client to take a calcium channel blocker in the morning

2. Without a heart transplant, this client will end up in end-stage heart failure. A transplant is the only treatment for a client with cardiomyopathy.

The client diagnosed with a myocardial infarction is six hours post-right femoral percutanous 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 straight2. The pressure dressing to the right femoral area is intact3. The client is complaining of numbness in the right foot4. The client's right pedal pulse is +3 and bounding

3. Any neurovascular assessment data that is abnormal requires intervention by the nurse; numbness may indicate decreased blood flow to the right foot

The client who has had a myocardial infarction is admitted to the telementry unit from intensive care. Which referral would be most appropriate for the client?1. Social worker2. Physical therapy3. Cardiac rehabilitation4. Occupation 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 exercises, diet teaching, and classes on modifying risk factors.

Which client would most likely be misdiagnosed for having a myocardial infarction?1. A 55 year old Caucasian male with crushing chest pain and diaphoresis2. A 60 year old Native American male with an elevated troponin level3. A 40 year old Hispanic female with a normal ECG4. An 80 year old Peruvian female with normal CK-MB at 12 hours

3. Clients who are misdiagnosed concerning MIs usually present with atypical symptoms. They tend to be female, younger than 55, members of a minority group, and have normal ECGs

The nurse is teaching a group of teens about prevention of heart disease. Which point should the nurse emphasize?1.Reduce abdominal fat.2. Avoid stress.3. Do not smoke or chew tobacco.4. Avoid alcoholic beverages.

3. Do not smoke or chew tobacco.

The client has just returned from a cardiac catherization. Which assessment data would warrant immediate intervention from the nurse?1. The client's BP is 110/70 and pulse is 902. The client's groin dressing is dry and intact3. The client refuses to keep the leg straight4. The client denies any

3. The client bends the legs, it could cause insertion site bleeding. This is arterial blood and the client could bleed to death very quickly, so this requires immediate intervention.

The client diagnosed with a myocardial infarction is on bedrest. The unlicensed assistive personnel is encouraging the client to move the legs. Which action should the nurse implement?1. Instruct the UAP to stop encouraging leg movements2. Report this behavior to the charge nurse as soon as possible3. Praise the UAP for encouraging the client to move legs4. 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 developing deep vein thrombosis, and moving the legs will prevent this from occurring.

Which cardiac enzyme would the nurse expect to elevate first in a client diagnosed with a myocardial infarction?

3. Troponin is the enzyme that elevates within 1 to 2 hours

Which population is at a higher risk for dying from a myocardial infarction?1. Caucasian Males2. Hispanic Females3. Asian Males4. African American Females

4. African American Females African American Females are 35% more likely to die from CAD than any other population. This population has significantly higher rates of HTN, and it occurs at a younger age. The higher risk of death from an MI is also attributed to a delay in seeking emergency care - an average of 11 hours

The client is 3 hours post myocardial infarction. Which data would warrant immediate intervention by the nurse?1. Bilateral peripheral pulses 2+2. The pulse oximeter reading is 96%3. The urine output is 240 mL in the last 4 hours4. Cool, clammy, diaphoretic skin

4. Cold, clammy skin is an indicator of cardiogenic shock, which is a complication of MI and warrants immediate intervention.

The nurse is assessing the client with chest pain to evaluate whether the client is suffering from angina or myocardial infarction (MI). Which symptom is indicative of an MI?1. Chest pain brought on by exertion or stress2. Substernal chest discomfort occurring at rest3. Substernal chest discomfort relieved by nitroglycerin or rest4. Substernal chest pressure relieved only by opioids

4. Substernal chest pressure relieved only by opioids is typically indicative of MI. Chest pain brought on by exertion or stress is indicative of angina. Substernal chest discomfort that occurs at rest is not necessarily indicative of MI; it could be a sign of unstable angina. Substernal chest discomfort relieved by nitroglycerin or rest is indicative of angina.

A client who had thrombolytic therapy is receiving a continuous infusion of sodium heparin. In the past hour, the client's blood pressure changed from 122/74 to 98/46 mm Hg. His pulse is rapid and weak. What is the nurse's first action at this time?A. Assess for signs of bleeding.B. Slow the heparin infusion rate.C. Document the blood pressure change.D. Stop the heparin infusion immediately.

His pulse is rapid and weak. What is the nurse's first action at this time?A. Assess for signs of bleeding.B. Slow the heparin infusion rate.C. Document the blood pressure change.D. Stop the heparin infusion immediately.

A client had a coronary artery bypass graft 2 days ago and has a new onset of atrial fibrillation. What diagnostic test will the nurse check that could explain this dysrhythmia?A. Arterial oxygen levelB. Serum potassiumC. Serum sodiumD. Blood urea nitrogen

BRationale: Hypokalemia after a coronary artery bypass graft procedure is a common cause of atrial fibrillation. Other complications may also include hypotension, hypothermia, hypertension, bleeding, cardiac tamponade, decreased level of consciousness, and anginal pain. Studies remain inconclusive on the role sodium plays in the development of atrial fibrillation. Elevated blood urea nitrogen levels may occur related to dehydration or decreased cardiac perfusion but have no connection to the development of atrial fibrillation.

Postoperative care of a patient undergoing coronary artery bypass graft (CABG) surgery includes monitoring for which of the following common complications? A. Dehydration B. Paralytic ileus C. Atrial dysrhythmias D. Acute respiratory distress syndrome

C. Postoperative dysrhythmias, specifically atrial dysrhythmias, are common in the first 3 days following CABG surgery. Although the other complications could occur, they are not common complications

he nurse is concerned that the client who had myocardial infarction (MI) has developed cardiogenic shock. Which of these findings indicates shock? Select all that apply. Bradycardia Cool, diaphoretic skin Crackles in the lung fields Respiratory rate of 12 Anxiety and restlessness Temperature of 100.4

Cool, diaphoretic skin Crackles in the lung fields Anxiety and restlessness Cool, diaphoretic skin: The client with shock has cool, moist skin.Crackles in the lung fields: Owing to extensive tissue necrosis (MI), the left ventricle cannot forward blood adequately, resulting in pulmonary congestion and crackles.Anxiety and restlessness: Owing to poor tissue perfusion, a change in mental status, anxiety, and restlessness are expected.All types of shock (except neurogenic) present with tachycardia. Owing to pulmonary congestion, the 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.

A patient was admitted to the emergency department 24 hours earlier with complaints of chest pain that were subsequently attributed to ST-segment-elevation myocardial infarction (STEMI). Which of the following complications of MI should the nurse anticipate? A. unstable angina B. cardiac tamponade C. sudden cardiac death D. cardiac dysrhythmias

D. The most common complication after MI is dysrhythmias, which are present in 80% of patients. Unstable angina is considered a precursor to MI rather than a complication. Cardiac tamponade is a rare event, and sudden cardiac death is defined as an unexpected death from cardiac causes; cardiac dysfunction in the period following an MI would not be characterized as sudden cardiac death.

Which of the following atypical symptoms may be present in the female client experiencing myocardial infarction (MI)? Select all that apply. Sharp, inspiratory chest pain Dyspnea Dizziness Extreme fatigue Anorexia

Dyspnea Dizziness Extreme fatigue

The nurse is providing a cardiac class for a women's group. The nurse emphasizes that 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

When planning care for a client in the emergency department, the nurse recognizes that which interventions are needed in the acute phase? Select all that apply. Morphine sulfate Oxygen Nitroglycerin Naloxone Acetaminophen Verapamil (Calan, Isoptin)

Morphine sulfate Oxygen Nitroglycerin: Morphine: Morphine is needed to reduce oxygen demand, preload, pain, and anxiety.Oxygen: will increase available oxygen for the ischemic myocardium.Nitroglycerin is used to reduce preload and chest pain.The client is given aspirin to chew; acetaminophen may be used for headache related to nitroglycerin. Owing to negative inotropic action, calcium channel blockers are used for angina, not for myocardial infarction (MI).

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 nitroglycerin2. Obtain a stat 12 Lead ECG3. Have the client sit down immediately4. Assess the client's vital signs

Administer sublingual nitroglycerin2. Obtain a stat 12 Lead ECG3. Have the client sit down immediately4. Assess the client's vital signs

To validate that the client has had a myocardial infarction (MI), the nurse assesses for positive findings on which tests?1. Creatine kinase-MB fraction (CK-MB) and alkaline phosphatase2. Homocysteine and C-reactive protein3. Total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterols4. Myoglobin and troponin

To validate that the client has had a myocardial infarction (MI), the nurse assesses for positive findings on which tests?1. Creatine kinase-MB fraction (CK-MB) and alkaline phosphatase2. Homocysteine and C-reactive protein3. Total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterols4. Myoglobin and troponin

18. 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

ANS: 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.

ANS: 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.

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

ANS: 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.

1. A nurse assesses a clients 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 clients 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

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 clients 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.

A group of nursing students are discussing atrial flutter. These students recognize that which of the following are seen with atrial flutter? Select all that apply:1) Ventricular rate of 220-300 bpm.2) Regular rhythm3) Saw-tooth pattern4) Measurable PR interval5) Long QRS interval

Answer(s): 2, 3The ATRIAL rate is 220-300 bpm. Ventricular is about 75-150. The rhythm is regular, with the P wave appearing as little flutter or a "saw tooth pattern". The PR interval is not measurable r/t this saw-tooth P wave. The QRS is normal.

A nurse on a CVT unit views the monitor and sees the patient in room 452 has just begun having occasional PVCs. Which action should the nurse take first?1) Check on the patient2) Check last magnesium and potassium levels3) Document the occurrence and watch for further PVCs4) Contact the physician

Answer: 1)Although electrolytes are likely the culprit, the nurse first needs to first assess the patient. Then, the nurse should look in the patient's chart and evaluate or request an order for electrolyte levels. This may eventually need to be documented, but the nurse can be held liable for neglect if he/she does not assess the patient first. The physician may or may not need to be contacted.

A nursing student is aware that which of the following is the treatment for unstable atrial flutter?1) Adenosine (Adenocard) 6 mg rapid IVP.2) Cardioversion with adjacent Heparin therapy3) Defibrillation STAT followed by CPR.4) Altemose 3 mg IVP over 1-2 seconds.

Answer: 2)Cardioversion is used if the patient is unstable. Anticoagulants are used if the arrhythmia has stuck around for 48 hr +. Adenosine may be used with a narrow QRS and regular RR interval. I made up Altemose.

Which of the following does the nursing student realize is the treatment for a stable patient presenting with QRS intervals above 0.12 seconds with a regular rhythm and a rate of 100-250 bpm?1) Atropine2) Defibrillation3) Amiodarone4) Adenosine

Answer: 3)This is describing ventricular tachycardia (QRS is a giveaway), and the treatment for a stable patient is Amiodarone or cardioversion. If the patient were unstable, we'd go ahead and defibrillate.

A 26-year-old client with atrial fibrillation that has not responded to medication therapy has arrived at the hospital for an elective cardioversion. Which of the following patient statements most concerns the nurse?1) "I can't wait to stop taking this Coumadin. I've been on this crap for weeks now."2) "I'm starving. I haven't eaten anything in 3 hours."3) "I feel really short of breath, can I lie down?"4) "I haven't taken my Digoxin since 9 o'clock last night. Is that okay?"

Answer: 3Patients with atrial fibrillation are at incredibly high risk for clots, even with anticoagulation therapy. Shortness of breath could indicate a PE, and this should be immediately investigated by the nurse. The patient should be NPO for at least 4 hr. prior to the procedure related to anesthesia use, but this is not as urgent of a concern. The patient should also withhold Digoxin therapy for 48 hours to ensure that, once cardioverted, NSR returns.

The nurse is preparing to administer adenosine to the patient with the following unstable atrial tach which is symptomatic. What should the nurse plan on having in the patient room? a) Physician b) Crash cart c) IV pump d) EKG monitor e) Lidocaine

Answer: A, B, and D. Adenosine is administered as a very quick IV push. The physician must be present in the room and the crash cart must be on hand. An ekg monitor should be in the room to monitor the effectiveness of the medication.

The nurse is providing discharge teaching to the client who has just received a pacemaker. Which of the following should the nurse include in the plan of care? SATA:A) Use your cell phone on the opposite side of your pacemakerB) You should avoid using a microwave from now onC) For the next week, it would be best to limit activity on the side with your new pacemakerD) You will need to inform airport security about your pacemaker before you fly anywhereE) It would be a good idea to check your pulse daily

Answer: A, C, D, and E. A cellphone should not be used near the pacemaker and it's best to keep the phone about half a foot away from the pacemaker. It is not necessary for the client to avoid using a microwave or other electrical devices. However, magnets should be kept away from the device. In order to prevent disruption of the leads after implantation (the most common complication), patients are often taught to limit activity on the affected side for awhile after implantation. Pulses are a good indicator of whether the pacemaker is supplying the body with enough cardiac output.

The nurse in the intensive care unit (ICU) hears an alarm sound in the patient's room. Arriving in the room, the patient is unresponsive, without a pulse, and a flat line on the monitor. What is the first action by the nurse?a) Administer atropine 0.5 mgb) Administer epinephrinec) Defibrillate with 360 joulesd) Begin cardiopulmonary resuscitation (CPR)

Answer: d)We cannot defibrillate asystole

An older client has a history of stable angina. Which modifiable risk factors will the nurse assess to guide the client's teaching plan? Select all that apply.A. Older ageB. Tobacco useC. Activity levelD. Serum lipid levelsE. Family historyF. Weight

B, C, D, FRationale: Modifiable risk factors are lifestyle choices that can be controlled by the client, such as smoking, activity level, control of serum lipid levels, and control of obesity through dietary management. Nonmodifiable risk factors are personal characteristics that cannot be altered or controlled. These risk factors, which interact with each other, include age, gender, family history, and ethnic background.

After teaching a patient with chronic stable angina about nitroglycerin, the nurse recognizes the need for further teaching when the patient states: A. "I will replace my nitroglycerin supply every 6 months." B. "I can take up to five tablets every 3 minutes for relief of my chest pain." C. "I will take acetaminophen (Tylenol) to treat the headache caused by nitroglycerin." D. "I will take the nitroglycerin 10 minutes before planned activity that usually causes chest pain."

B. The recommended dose of nitroglycerin is one tablet taken sublingually (SL) or one metered spray for symptoms of angina. If symptoms are unchanged or worse after 5 minutes, the patient should be instructed to activate the emergency medical services (EMS) system.

CAD can diminish the myocardial blood supply until deprivation impairs myocardial metabolism enough to cause________, a local state in which the cells are temporarily deprived of blood supply A. infarction B. ischemia C. necrosis D. inflammation

B. ischemia
