504 Exam 1 TestBank Questions

An emergency department nurse obtains the health history of a client. Which statement by the client would 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.

A nurse teaches a client who experiences occasional premature atrial contractions (PACs) accompanied by palpitations that resolve spontaneously without treatment. Which statement would the nurse include in this client's teaching? a. "Minimize or abstain from caffeine." b. "Lie on your side until the attack subsides." c. "Use your oxygen when you experience PACs." d. "Take amiodarone daily to prevent PACs."

ANS: A PACs usually have no hemodynamic consequences. For a client experiencing infrequent PACs, the nurse would 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 would try lifestyle changes to control them.

A nurse cares for a client with infective endocarditis. Which infection control precautions would the nurse use? a. Standard Precautions b. Bleeding Precautions c. Reverse isolation d. Contact isolation

ANS: A The client with infective endocarditis does not pose any specific threat of transmitting the causative organism. Standard Precautions would be used. Bleeding Precautions, reverse isolation, or Contact Precautions are not necessary.

A nurse prepares to discharge a client with a cardiac dysrhythmia who is prescribed home health care services. Which priority information would be communicated to the home health nurse upon discharge? a. Medication orders for home 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 might be used to plan care, but not as the priority.

A nurse assesses a client who is recovering from a myocardial infarction. The client's blood pressure is 140/88 mm Hg. What action would the nurse take first? a. Compare the results with previous blood pressure readings. b. Increase the intravenous fluid rate because these readings are low. c. Immediately notify the primary health care provider of the elevated blood pressure. d. Document the finding in the client's chart as the only action.

ANS: A The most recent range for normal blood pressure is less than 140 mm Hg systolic and less than 90mm Hg diastolic. This client's blood pressure is at the upper range of acceptable, so the nurse would compare the client's current reading with those previously recorded before doing anything else. The reading is not low, so the nurse would not increase IV fluids, nor would the nurse necessarily notify the primary health care provider. Documentation is important, but the nurse first checks previous readings.

While assessing a client on a cardiac unit, a nurse identifies the presence of an S3 gallop. What action would the nurse take next? a. Assess for symptoms of left-sided heart failure. b. Document this as a normal finding. c. Call the primary 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.

A nurse is caring for a client with a history of renal insufficiency who is scheduled for a cardiac catheterization. What actions would 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, fluids may be given 12 to 24 hours before the procedure for renal protection. Hydration would continue after the procedure. The client would be assessed for allergies to iodine, including shellfish; the contrast medium used during the catheterization contains iodine. Baseline renal labs would be assessed. A Foley catheter and central venous catheter are not required for the procedure and would only increase the client's risk for infection. Prophylactic antibiotics are not administered prior to a cardiac catheterization.

A nurse is teaching a client who has premature ectopic beats. Which education would the nurse include in this client's 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 f. Types of aerobic exercise

ANS: A, B, D A client who has premature beats or ectopic rhythms would be taught to stop smoking, manage stress, take medications as prescribed, and report adverse effects of medications. Clients with premature beats are not at risk for vasovagal attacks or potassium imbalances. While exercise is beneficial, aerobic exercise is not specifically linked to this client's educational needs.

A nurse assesses clients on a cardiac unit. Which clients would 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 with acute exacerbations of systemic connective tissue disease, including SLE; with Dressler 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 injuries do not increase clients' risk for acute pericarditis.

The nurse is reviewing risk factors in a client who has atherosclerosis. Which findings are most concerning? (Select all that apply.) a. Elevated low-density lipoprotein (LDL-C) b. Decreased levels of high-density lipoprotein cholesterol (HDL-C) c. Asian ethnicity d. History of smoking e. Blood pressure: 142/92 mm Hg on one occasion

ANS: A, B, D Elevated levels of lipids (fats) such as low-density lipoprotein cholesterol (LDL-C) and decreased levels of high-density lipoprotein cholesterol can cause chemical damage to blood vessel walls. Smoking can cause endothelial damage in addition to increasing a client's carbon monoxide levels. African American and Hispanic ethnicities carry an increased risk for atherosclerosis. Hypertension does increase atherosclerosis risk, but an elevated reading on one occasion is not classified as hypertension.

A nurse is assessing a client with left-sided heart failure. For which clinical manifestations would the nurse assess? (Select all that apply.) a. Pulmonary crackles b. Confusion c. Pulmonary hypertension d. Dependent edema e. Cough that worsens at night f. Jugular venous distention

ANS: A, B, E Left-sided heart failure occurs with a decrease in contractility of the heart or an increase in afterload. Most of the signs will be noted in the respiratory system. These include crackles, confusion (due to decreased oxygenation), and cough. Right ventricular failure is associated with pulmonary hypertension, edema, and jugular venous distention.

A nurse teaches a client with a new permanent pacemaker. Which instructions would the nurse include in this client's 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 would 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 would 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 would be advised of restrictions on physical activity for 8 weeks to allow the pacemaker to settle in place. The client would never apply pressure over the generator and would avoid tight clothing. The client would never have MRI because, whether turned on or off, the pacemaker contains metal. The client would be advised to inform all health care providers that he or she has a pacemaker.

A nurse evaluates laboratory results for a client with heart failure. Which results would the nurse expect? (Select all that apply.) a. Hematocrit: 32.8% b. Serum sodium: 130 mEq/L (130 mmol/L) c. Serum potassium: 4.0 mEq/L (4.0 mmol/L) d. Serum creatinine: 1.0 mg/dL (88.4 mcmol/L) e. Proteinuria f. Microalbuminuria

ANS: A, B, E, F A hematocrit of 32.8% is low (should be 42.6%), indicating a dilutional ratio of red blood cells to fluid. A serum sodium of 130 mEq/L (130 mmol/L) is low because of hemodilution. Microalbuminuria and proteinuria are present, indicating a decrease in renal filtration. These are early warning signs of decreased compliance of the heart. The potassium level is normal and the serum creatinine level is normal.

A nurse cares for a client who is recovering from a right-sided heart catheterization. For which complications of this procedure would the nurse assess? (Select all that apply.) a. Thrombophlebitis b. Stroke c. Pulmonary embolism d. Myocardial infarction e. Cardiac tamponade f. Dysrhythmias

ANS: 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, myocardial infarction, and dysrhythmias are complications of left-sided heart catheterizations.

A nurse cares for a client with congestive heart failure who has a regular cardiac rhythm of 128 beats/min. For which physiologic alterations would 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, C, 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.

A nurse is caring for a client who was admitted with hypertrophic cardiomyopathy (HCM). What interprofessional care does the nurse anticipate providing? (Select all that apply.) a. Administering beta blockers b. Administering high-dose furosemide c. Preparing for a cardiac catheterization d. Loading the client on digitalis e. Instructing the client to avoid strenuous exercise f. Teaching the client how to use the CardioMEMSTM

ANS: A, C, E Management of obstructive HCM includes administering negative inotropic agents such as beta-adrenergic blocking agents (carvedilol) and calcium antagonists (verapamil). Vasodilators, diuretics, nitrates, and cardiac glycosides are contraindicated in patients with obstructive HCM. Strenuous exercise is also prohibited. Echocardiography, radionuclide imaging, and angiocardiography during cardiac catheterization are performed to diagnose and differentiate cardiomyopathies. The CardioMEMSTM device is used with clients who have heart failure.

The nurse working in the emergency department knows that which factors are commonly related to aneurysm formation? (Select all that apply.) a. Atherosclerosis b. Down syndrome c. Frequent heartburn d. History of hypertension e. History of smoking f. Hyperlipidemia

ANS: A, D, E, F Atherosclerosis, hypertension, hyperlipidemia, hyperlipidemia, and smoking are the most commonly related factors. Down syndrome and heartburn have no relation to aneurysm formation.

A nurse teaches a client with heart failure about energy conservation. Which statement would the nurse include in this client's teaching? a. "Walk until you become short of breath, and then walk back home." b. "Begin walking 200 feet a day three times a week." c. "Do not lift heavy weights for 6 months." d. "Eat plenty of protein to build your strength."

ANS: B A client who has heart failure would be taught to conserve energy and given an exercise plan. The client should begin walking 200-400 feet a day at home three times a week. The client should not walk until becoming short of breath because he or she may not make it back home. The lifting restriction is specifically for clients after valve replacements. Protein does help build strength, but this direction is not specific to heart failure.

A nurse is assessing clients on a medical-surgical unit. Which client would 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. Other risk factors include hypertension (HTN), previous ischemic stroke, transient ischemic attack (TIA) or other thromboembolic event, diabetes mellitus, heart failure, obesity, hyperthyroidism, chronic kidney disease, excessive alcohol use, and mitral valve disease. The other conditions do not place these clients at higher risk for atrial fibrillation.

A nurse evaluates prescriptions for a client with chronic atrial fibrillation. Which medication would the nurse expect to find on this client's medication administration record to prevent a common complication of this condition? a. Sotalol b. Warfarin c. Atropine d. Lidocaine

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 preventing this complication.

A nurse cares for a client who has a heart rate averaging 56 beats/min with no adverse symptoms. Which activity modification would 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.

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 would the nurse include in this client's 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 won't need to change your diet."

ANS: B Clients at risk for cardiovascular diseases should follow the American Heart Association guidelines to combat obesity and improve cardiac health. The nurse would 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 would 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.

A nurse assesses a client with tachycardia. Which clinical manifestation requires immediate intervention by the nurse? a. Midsternal 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 would 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.

A nurse assesses a client who is recovering from a heart transplant. Which assessment findings would 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 f. Fatigue

ANS: A, B, C, F Clinical findings 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.

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 would 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.

A nurse assesses a client with atrial fibrillation. Which manifestation would 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.

A nurse assesses a client with mitral valve stenosis. What clinical sign or symptom would alert the nurse to the possibility that the client's 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 signs and symptoms do not relate to the progression of mitral valve stenosis.

A nurse assists with the cardioversion of a client experiencing acute atrial fibrillation. What action would the nurse take prior to the cardioversion? a. Administer intravenous adenosine. b. Turn off oxygen therapy. c. Ensure that a tongue blade is available. d. Position the client on the left side.

ANS: B For safety during cardioversion, the nurse would turn off any oxygen therapy to prevent fire. The other interventions are not appropriate for a cardioversion. The client would be placed in a supine position.

After administering the first dose of captopril to a client with heart failure, the nurse implements interventions to decrease complications. Which intervention is most important for the nurse to implement? 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 assistive personnel to bathe the client. d. Monitor potassium levels and check for symptoms of hypokalemia.

ANS: B Hypotension is a side effect of ACE inhibitors such as captopril. Clients with a fluid volume deficit should have their volume replaced or start at a lower dose of the drug to minimize this effect. The nurse would 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 assistive personnel to provide hygiene is not a priority. The client would be encouraged to complete activities of daily living as independently as possible. The nurse would monitor for hyperkalemia, not hypokalemia, especially if the client has renal insufficiency secondary to heart failure.

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. What action would the nurse take next? a. Administer intravenous diltiazem. 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 would 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 would 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.

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.

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?" What is the best response by the nurse? 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.

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 would the nurse be prepared to implement while this client waits for surgery? a. Administration of IV furosemide b. Initiation of an external pacemaker c. Assistance with endotracheal intubation d. Placement of central venous access

ANS: B The RCA supplies the right atrium, right ventricle, inferior portion of the left ventricle, and 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 would be available for the client. Furosemide, intubation, and central venous access will not address the primary complication of RCA occlusion, which is AV node (and possibly SA node) malfunction.

After teaching a client who has an implantable cardioverter-defibrillator (ICD), a nurse assesses the client's understanding. Which statement by the client indicates correct understanding of the teaching? a. "I would wear a snug-fitting shirt over the ICD." b. "I will avoid sources of strong electromagnetic fields." c. "I would 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, such as devices emitting microwaves (not microwave ovens); transformers; radio, television, and radar transmitters; large electrical generators; metal detectors, including handheld security devices at airports; antitheft devices; arc welding equipment; and sources of 60-cycle (Hz) interference. Also avoid leaning directly over the alternator of a running motor of a car or boat. Clients would avoid tight clothing, which could cause irritation over the ICD generator. The client would be encouraged to exercise but would 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 would continue all prescribed medications.

A nurse assesses a client with pericarditis. Which assessment finding would 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.

A nurse cares for a client who is prescribed magnetic resonance imaging (MRI) of the heart. The client's health history includes a previous myocardial infarction and pacemaker implantation. What action would the nurse take? a. Schedule an electrocardiogram just before the MRI. b. Notify the primary health care provider before scheduling the MRI. c. Request lab for cardiac enzymes from the primary health care provider. 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 would call the primary health care provider and report that the client has a pacemaker so that he or she can order other diagnostic tests. The client does not need an electrocardiogram, cardiac enzymes, or increased fluids. Some newer MRI scanners have eliminated the possibility of complications due to implants, but the nurse needs to notify the primary health care provider.

A nurse obtains the health history of a client who is newly admitted to the medical unit. Which statement by the client would 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."

ANS: B Weight gain can result from fluid accumulation in the interstitial spaces. This is known as edema. The nurse would note whether the client feels that his or her shoes or rings are tight, and would observe, when present, an indentation around the leg where the socks end. The other answers do not describe edema.

An emergency department nurse assesses a female client. Which assessment findings would 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 symptoms—indigestion 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.

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 (2.9 mmol/L) c. Warmth and redness at the site d. Expanding groin hematoma e. Rhythm changes on the cardiac monitor f. Oxygen saturation 93% on room air

ANS: B, D, E After a cardiac catheterization, the nurse monitors vital signs, entry site, cardiac function, and distal circulation. The potassium is very low which can lead to dysrhythmias. An expanding hematoma signifies bleeding. Rhythm changes on the monitor are a known complication. These findings would require prompt action. The client's 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. The oxygen saturation is slightly low but not critical and there is no baseline to compare it to.

A nurse prepares a client for a pharmacologic stress echocardiogram. What actions would the nurse take when preparing this client for the procedure? (Select all that apply.) a. Assist the primary health care provider to place a central venous access device. b. Prepare for continuous blood pressure and pulse monitoring. c. Administer the client's 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, would be performed. Beta blockers are often held prior to the procedure as they lower the heart rate and may result in inaccurate results.

A client with a known abdominal aortic aneurysm reports dizziness and severe abdominal pain. The nurse assesses the client's blood pressure at 82/40 mm Hg. What actions by the nurse are most important? (Select all that apply.) a. Administer pain medication. b. Assess distal pulses every 10 minutes. c. Have the client sign a surgical consent. d. Notify the Rapid Response Team. e. Take vital signs every 10 minutes.

ANS: B, D, E This client may have a ruptured/rupturing aneurysm. The nurse would notify the Rapid Response team and perform frequent client assessments. Giving pain medication will lower the client's blood pressure even further. The nurse cannot have the client sign a consent until the surgeon has explained the procedure.

A telemetry nurse assesses a client who has a heart rate of 35 beats/min on the cardiac monitor. Which assessment would 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 could have hemodynamic consequences. The client is at risk for inadequate cerebral perfusion. The nurse would assess for level of consciousness, dizziness, confusion, syncope, chest pain, shortness of breath. Although the other assessments would be completed, the nurse would assess the client's neurologic status next.

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 not unexpected at the site. Urinary output less than intake may or may not be significant.

After teaching a client who is recovering from a heart transplant to change positions slowly, the client asks, "Why is this important?" How would 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.

A nurse administers prescribed adenosine to a client. Which response would 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 with long pauses, nausea, or vomiting. Adenosine has no impact on intraocular pressure nor does it cause increased heart rate or hypertensive crisis.

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." What is the nurse's best response? a. "Chili is high in fat and calories; it would be a good idea to stop eating it." b. "The primary health care provider has prescribed an antacid every morning." c. "What do you understand about what happened to you?" d. "When did you start experiencing this indigestion?"

ANS: C Clients who experience myocardial infarction often respond with denial, which is a defense mechanism. The nurse would 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 client's misconception about recent pain and the cause of that pain.

A nurse cares for a client with atrial fibrillation who reports fatigue when completing activities of daily living. What intervention would the nurse implement to address this client's concerns? a. Administer oxygen therapy at 2 L per nasal cannula. b. Provide the client with a sleeping pill to stimulate rest. c. Schedule periods of exercise and rest during the day. d. Ask assistive personnel (AP) 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 would schedule periods of exercise and rest during the day to decrease fatigue. The other interventions will not assist the client with performing self-care activities and there is no indication for oxygen.

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.

A nurse assesses female client who is experiencing a myocardial infarction. Which clinical manifestation would the nurse expect? a. Excruciating pain on inspiration b. Left lateral chest wall pain c. Fatigue and shortness of breath d. Numbness and tingling of the arm

ANS: C In women, fatigue, shortness of breath, and indigestion may be the major symptoms of myocardial infarction caused by poor cardiac output. Chest pain is the classic symptom of myocardial infarction and can be present in women. Pain on inspiration may be related to a pleuropulmonary cause. Numbness and tingling of the arm could also be related to the myocardial infarction, but are not known to be specific symptoms for women having and MI.

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. What action would the nurse take next? 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 left pulse would be compared with the right, and pulses would 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 would be notified. Simply documenting the findings is inappropriate. The leg would be positioned below the level of the heart to increase blood flow to the distal portion of the leg. Increasing intravenous fluids will not address the client's problem.

A nurse assesses clients on a medical-surgical unit. Which client would 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 man with colorectal cancer. c. A 65-year-old woman with diabetes mellitus. d. A 53-year-old postmenopausal woman who takes bisphosphonates.

ANS: C Of the options, the client with diabetes has a two- to four-fold increase in risk for death due to cardiovascular disease. Advancing age also increases risk, but not as much. Asthma, colorectal cancer, and bisphosphonate therapy do not increase the risk for cardiovascular disease.

A nurse assesses an older adult client who has multiple chronic diseases. The client's heart rate is 48 beats/min. What action would the nurse take first? a. Document the finding in the chart. b. Initiate external pacing. c. Assess the client's medications. d. Administer 1 mg of atropine.

ANS: C Pacemaker cells in the conduction system decrease in number as a person ages, potentially resulting in bradycardia. However, the nurse would first check the medication reconciliation for medications that might cause such a drop in heart rate, and then would inform the primary health care provider. Documentation is important, but it is not the first action. The heart rate is not low enough for atropine or an external pacemaker to be needed unless the client is symptomatic, which is not apparent.

A nurse prepares a client for cardiac catheterization. The client states, "I am afraid I might die." What is the nurse's best response? a. "This is a routine test and the risk of death is very low." b. "Would you like to speak with a chaplain prior to test?" c. "Tell me more about your concerns about the test." d. "What support systems do you have to assist you?"

ANS: C The nurse would discuss the client's feelings and concerns related to the cardiac catheterization. The nurse would not provide false hope or push the client's concerns off on the chaplain. The nurse would address support systems after addressing the client's current issue.

A new nurse is caring for a client with an abdominal aneurysm. What action by the new nurse requires the nurse's mentor to intervene? a. Assesses the client for back pain. b. Auscultates over abdominal bruit. c. Measures the abdominal girth. d. Palpates the abdomen in four quadrants.

ANS: D Abdominal aneurysms should never be palpated as this increases the risk of rupture. The nurse mentoring the new nurse would intervene when the new nurse attempts to do this. The other actions are appropriate.

An emergency department nurse triages clients who present with chest discomfort. Which client would the nurse plan to assess first? a. Client who describes pain as a dull ache. b. Client who reports moderate pain that is worse on inspiration. c. Client who reports cramping substernal pain. d. Client who describes intense squeezing pressure across the chest.

ANS: D All clients who have chest pain would be assessed more thoroughly. To determine which client would be seen first, the nurse must understand common differences in pain descriptions. Intense stabbing and viselike (squeezing) substernal pain or pressure that spreads through the client 's chest, arms, jaw, back, or neck are indicatives of a myocardial infarction. The nurse would plan to see this client first to prevent cardiac cell death. A dull ache, pain that gets worse with inspiration, and cramping pain are not usually associated with myocardial infarction.

A nurse assesses a client who is scheduled for a cardiac catheterization. Which assessment would the nurse complete as the priority prior to this procedure? a. Client's 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 would 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. It is important for the nurse to assess anxiety, mobility, and baseline cardiac status, but allergies take priority for client safety.

A nurse assesses a client after administering a prescribed beta blocker. Which assessment would the nurse expect to find? a. Blood pressure increased from 98/42 to 132/60 mm Hg. b. Respiratory rate decreased from 25 to 14 breaths/min. c. Oxygen saturation increased from 88% to 96%. d. Pulse decreased from 100 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 may drop because of decreased HR, but slowing the rate may allow for better filling and better cardiac output.

A nurse teaches a client who has a history of heart failure. Which statement would the nurse include in this client's discharge teaching? a. "Avoid drinking more than 3 quarts (3 L) 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 would 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.

A nurse teaches a client who is prescribed digoxin therapy. Which statement would 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.

A nurse assesses a client's electrocardiograph tracing and observes that not all QRS complexes are preceded by a P wave. How would 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.

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 would 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 would position the client in a comfortable position, which usually is upright and leaning slightly forward. An ice pack and neck rub will not relieve this pain. Dimming the lights will also not help the pain.

A nurse cares for a client who has advanced cardiac disease and states, "I am having trouble breathing while I'm sleeping at night." What is the nurse's best response? a. "I will consult your primary health care provider to prescribe a sleep study." 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 would 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 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 would 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 the concerns are not valid. 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 immediately calling for the chaplain or psychiatrist. The nurse would not jump to conclusions and suggest taking the client off the transplant list, which is the best treatment option

A nurse assesses a client after administering the first dose of a nitrate. The client reports a headache. What action would the nurse take? a. Initiate oxygen therapy. b. Hold the next dose. c. Instruct the client to drink water. d. Administer PRN acetaminophen.

ANS: D The vasodilating effects of nitrates frequently cause clients to have headaches during the initial period of therapy. The nurse would inform the client about this side effect and offer a mild analgesic, such as acetaminophen. The client's headache is not related to hypoxia or dehydration; therefore, applying oxygen and drinking water would not help. The client needs to take the medication as prescribed to prevent angina; the medication would not be held.

A nurse prepares to defibrillate a client who is in ventricular fibrillation. Which intervention is appropriate for the nurse to perform prior to defibrillating this client? a. Make sure that 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 J. 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. Defibrillation is done in asynchronous mode. Equipment would not be tested before a client is defibrillated because this is an emergency procedure; equipment would be checked on a routine basis. Defibrillation takes priority over any medications.

A nurse supervises an assistive personnel (AP) applying electrocardiographic monitoring. Which statement would the nurse provide to the AP related to this procedure? a. "Clean the skin and clip hairs if needed." b. "Add gel to the electrodes prior to applying them." c. "Place the electrodes on the posterior chest." d. "Turn off oxygen prior to monitoring the client."

ANS: A To ensure the best signal transmission, the skin would be clean and hairs clipped. Electrodes would be placed on the anterior chest, and no additional gel is needed. Oxygen has no impact on electrocardiographic monitoring.

A nurse is teaching a client with heart failure who has been prescribed enalapril. Which statement would 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.

A nurse admits a client who is experiencing an exacerbation of heart failure. What action would the nurse take first? a. Assess the client's respiratory status. b. Draw blood to assess the client's serum electrolytes. c. Administer intravenous furosemide. d. Ask the client about current medications.

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

A nurse assesses clients on a cardiac unit. Which client would 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 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.

A nurse cares for a client with right-sided heart failure. The client asks, "Why do I need to weigh myself every day?" How would 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 clients 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 lb (1 kg). Weight changes are the most reliable indicator of fluid loss or gain. The other responses do not address the importance of monitoring fluid retention or loss.

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." What is the best response by the nurse? a. "I can stay if you 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.

A nurse assesses a client who had a myocardial infarction and has a blood pressure of 88/58 mm Hg. Which additional assessment finding would 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 saturation and perfusion. The client may not be able to compensate for long and decreased oxygenation and cool, clammy skin will occur later.

A nurse assesses a client who has mitral valve regurgitation. For which cardiac dysrhythmia would 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.

A nurse is providing discharge teaching to a client recovering from a heart transplant. Which statement would the nurse include? 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 Clients who have had heart transplants must take immunosuppressant therapy for the rest of their lives. The nurse would teach this client to avoid crowds and sick people to reduce the risk of becoming ill him- or herself. These medications do not place clients at risk for bleeding, orthostatic hypotension, or changes in heart rate. Orthostatic hypotension from the denervated heart is generally only a problem in the immediate postoperative period.

A nurse assesses a client who has a history of heart failure. Which question would the nurse ask to assess the extent of the client's heart failure? a. "Do you have trouble breathing or chest pain?" b. "Are you still 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 and fatigue. 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.

A client presents to the emergency department with a thoracic aortic aneurysm. Which findings are most consistent with this condition? (Select all that apply.) a. Abdominal tenderness b. Difficulty swallowing c. Changes in bowel habits d. Shortness of breath e. Hoarseness

ANS: B, E Signs of a thoracic aortic aneurysm include shortness of breath, hoarseness, and difficulty swallowing. Pain is often rated as a 10 on a 10-point scale. Bowel habits are not related.

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?" What is the nurse's best response? 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.
