Care for Patients With Cardiac Problems, Inflammatory and Structural Heart Disorders

What finding should the nurse expect during the assessment of a young adult with infective endocarditis (IE)? a. Substernal chest pressure b. A new regurgitant murmur c. A pruritic rash on the chest d. Involuntary muscle movement

ANS: B New regurgitant murmurs occur in IE because vegetations on the valves prevent valve closure. Substernal chest discomfort, rashes, and involuntary muscle movement are clinical manifestations of other cardiac disorders such as angina and rheumatic fever.

Which finding for a patient with mitral valve stenosis would be of most concern to the nurse? a. Diastolic murmur b. Peripheral edema c. Shortness of breath on exertion d. Right upper quadrant tenderness

ANS: C The pressure gradient changes in mitral stenosis lead to fluid backup into the lungs, resulting in hypoxemia and dyspnea. The other findings also may be associated with mitral valve disease but are not indicators of hypoxemia, which is a priority.

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.

The nurse is caring for a patient with aortic stenosis. Which assessment data would be most important to report to the health care provider? a. The patient reports chest pressure when ambulating. b. A loud systolic murmur is heard along the right sternal border. c. A thrill is palpated at the second intercostal space, right sternal border. d. The point of maximum impulse (PMI) is at the left midclavicular line.

ANS: A Chest pressure (or pain) occurring with aortic stenosis is caused by cardiac ischemia, and reporting this information would be a priority. A systolic murmur and thrill are expected in a patient with aortic stenosis. A PMI at the left midclavicular line is normal.

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 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 patient with aortic stenosis has acute pain due to decreased coronary blood flow. What would be an appropriate nursing intervention for this patient? a. Promote rest to decrease myocardial oxygen demand. b. Teach the patient about the need for anticoagulant therapy. c. Teach the patient to use sublingual nitroglycerin for chest pain. d. Raise the head of the bed 60 degrees to decrease venous return.

ANS: A Rest is recommended to balance myocardial oxygen supply and demand and to decrease chest pain. The patient with aortic stenosis requires higher preload to maintain cardiac output, so nitroglycerin and measures to decrease venous return are contraindicated. Anticoagulation is not recommended unless the patient has atrial fibrillation.

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.

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.

When planning care for a patient hospitalized with a streptococcal infective endocarditis (IE), which intervention is appropriate for the nurse to include? a. Arrange for placement of a long-term IV catheter. b. Monitor labs for levels of streptococcal antibodies. c. Teach the importance of completing all oral antibiotics. d. Encourage the patient to begin regular aerobic exercise.

ANS: A Treatment for IE involves 4 to 6 weeks of IV antibiotic therapy to eradicate the bacteria, which will require a long-term IV catheter such as a peripherally inserted central catheter (PICC) line. Rest periods and limiting physical activity to a moderate level are recommended during the treatment for IE. Oral antibiotics are not effective in eradicating the infective bacteria that cause IE. Blood cultures, rather than antibody levels, are used to monitor the effectiveness of antibiotic therapy.

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.

A nurse collaborates with assistive personnel (AP) to provide care for a client with congestive heart failure. Which instructions would the nurse provide to the AP when delegating care for this client? (Select all that apply.) a. "Reposition the client every 2 hours." b. "Teach the client to perform deep-breathing exercises." c. "Accurately record intake and output." d. "Use the same scale to weigh the client each morning." e. "Place the client on oxygen if the client becomes short of breath."

ANS: A,C,D The AP should reposition the client every 2 hours to improve oxygenation and prevent atelectasis. The AP can also accurately record intake and output, and use the same scale to weigh the client each morning before breakfast. APs are not qualified to teach clients or assess the need for and provide oxygen therapy.

After teaching a client with congestive heart failure (CHF), the nurse assesses the client's understanding. Which client statements indicate a correct understanding of the teaching related to nutritional intake? (Select all that apply.) a. "I'll read the nutritional labels on food items for salt content." b. "I will drink at least 3 L of water each day." c. "Using salt in moderation will reduce the workload of my heart." d. "I will eat oatmeal for breakfast instead of ham and eggs." e. "Substituting fresh vegetables for canned ones will lower my salt intake." f. "Salt substitutes are a good way to cut down on sodium in my diet."

ANS: A,D,E Nutritional therapy for a client with CHF is focused on decreasing sodium and water retention to decrease the workload of the heart. The client would be taught to read nutritional labels on all food items, omit table salt and foods high in sodium (e.g., ham and canned foods), and limit water intake to a normal 2 L/day. Salt substitutes typically contain potassium, so although they are not strictly banned, clients would have to have their renal function and serum potassium monitored while using them. It would be safer to avoid them.

The nurse is caring for a patient admitted with mitral valve regurgitation. Which information obtained by the nurse should be reported to the health care provider immediately? a. The patient has 4+ peripheral edema. b. The patient has diffuse bilateral crackles. c. The patient has a loud systolic murmur across the precordium. d. The patient has a palpable thrill felt over the left anterior chest.

ANS: B Crackles that are audible throughout the lungs indicate that the patient is experiencing severe left ventricular failure with pulmonary congestion and needs immediate interventions such as diuretics. A systolic murmur and palpable thrill would be expected in a patient with mitral regurgitation. Although 4+ peripheral edema indicates a need for a change in therapy, it does not need to be addressed urgently.

Which assessment finding(s) indicate to the nurse that a patient with infective endocarditis has decreased cardiac output? a. Fever, chills, and diaphoresis b. Urine production of 25 mL/hr c. Increase in heart rate of 15 beats/min with walking d. Petechiae on the inside of the mouth and conjunctiva

ANS: B Decreased renal perfusion caused by inadequate cardiac output will lead to decreased urine output. Petechiae, fever, chills, and diaphoresis are symptoms of IE but are not caused by decreased cardiac output. An increase in pulse rate of 15 beats/min is normal with exercise.

A patient is admitted to the hospital with possible acute pericarditis. What diagnostic test would the nurse expect the patient to undergo? a. Blood cultures b. Echocardiography c. Cardiac catheterization d. 24-hour Holter monitor

ANS: B Echocardiograms are useful in detecting the presence of the pericardial effusions associated with pericarditis. Blood cultures are not indicated unless the patient has evidence of sepsis. Cardiac catheterization and 24-hour Holter monitor are not diagnostic procedures for pericarditis.

Which assessment finding in a patient who is admitted with infective endocarditis (IE) is most important to communicate to the health care provider? a. Muscle aching b. Right flank pain c. Janeway's lesions on the palms d. Temperature 100.7° F (38.1° C)

ANS: B Flank pain indicates possible embolization to the kidney and may require diagnostic testing such as a renal arteriogram and interventions to improve renal perfusion. The other findings are typically found in IE but do not require any new interventions.

After receiving change-of-shift report on four patients, which patient should the nurse assess first? a. Patient with rheumatic fever who has sharp chest pain with a deep breath. b. Patient with acute aortic regurgitation whose blood pressure is 86/54 mm Hg. c. Patient with infective endocarditis who has a murmur and splinter hemorrhages. d. Patient with dilated cardiomyopathy who has bilateral crackles at the lung bases.

ANS: B Hypotension in patients with acute aortic regurgitation may indicate cardiogenic shock. The nurse should immediately assess this patient for other findings such as dyspnea, chest pain or tachycardia. The findings in the other patients are typical of their diagnoses and do not indicate a need for urgent assessment and intervention.

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.

How should the nurse assess the patient with pericarditis for evidence of a pericardial friction rub? a. Listen for a rumbling, low-pitched, systolic murmur over the left anterior chest. b. Auscultate with the diaphragm of the stethoscope on the lower left sternal border. c. Ask the patient to cough during auscultation to distinguish the sound from a pleural friction rub. d. Feel the precordial area with the palm of the hand to detect vibrations with cardiac contraction.

ANS: B Pericardial friction rubs are best heard with the diaphragm at the lower left sternal border. The nurse should ask the patient to hold his or her breath during auscultation to distinguish the sounds from a pleural friction rub. Friction rubs are not typically low pitched or rumbling and are not confined to systole. Rubs are not assessed by palpation.

The nurse suspects cardiac tamponade in a patient who has acute pericarditis. How should the nurse assess for the presence of pulsus paradoxus? a. Subtract the diastolic blood pressure from the systolic blood pressure. b. Note when Korotkoff sounds are heard during both inspiration and expiration. c. Check the electrocardiogram (ECG) for variations in rate during the respiratory cycle. d. Listen for a pericardial friction rub that persists when the patient is instructed to stop breathing.

ANS: B Pulsus paradoxus exists when there is a gap of greater than 10 mm Hg between when Korotkoff sounds can be heard during only expiration and when they can be heard throughout the respiratory cycle. The other methods described would not be useful in determining the presence of pulsus paradoxus. The difference between the diastolic blood pressure and the systolic blood pressure is known as the pulse pressure.

After receiving information about four patients during change-of-shift report, which patient should the nurse assess first? a. Patient with acute pericarditis who has a pericardial friction rub. b. Patient who has just returned to the unit after balloon valvuloplasty. c. Patient who has hypertrophic cardiomyopathy and a heart rate of 116. d. Patient with a mitral valve replacement who has an anticoagulant scheduled.

ANS: B The patient who has just arrived after balloon valvuloplasty will need assessment for complications such as bleeding and hypotension. The information about the other patients is consistent with their diagnoses and does not indicate any complications or need for urgent assessment or intervention.

Which admission order written by the health care provider for a patient admitted with infective endocarditis (IE) and a fever would be a priority for the nurse to implement? a. Administer ceftriaxone 1 gram IV. b. Order blood cultures from two sites. c. Schedule a transesophageal echocardiogram. d. Give acetaminophen (Tylenol) PRN for fever.

ANS: B Treatment of the IE with antibiotics should be started as quickly as possible, but it is essential to obtain blood cultures before starting antibiotic therapy to obtain accurate sensitivity results. The echocardiogram and acetaminophen administration also should be implemented rapidly, but the blood cultures (and then administration of the antibiotic) have the highest priority.

A nurse prepares to discharge a client who has heart failure. Based on national quality measures, what actions would the nurse complete prior to discharging this client? (Select all that apply.) a. Teach the client about energy conservation techniques. b. Ensure that the client is prescribed a beta blocker. c. Document a discussion about advanced directives. d. Confirm that a postdischarge nurse visit has been scheduled. e. Consult a social worker for additional resources. f. Care transition record transmitted to next level of care within 7 days of discharge.

ANS: B, C, D, F National quality measures aim to decrease heart failure readmission by proper preparation for discharge. These measures include :(1) beta blocker prescribed for left ventricular dysfunction at discharge, (2) postdischarge follow-up appointment scheduled within 7 days of discharge with documentation of location, date, and time. (3) care transition record transmitted to next level of care within 7 days of discharge. (4) documentation of discussion of advance directives/advance care planning with a health care provider, (5) documentation of execution of advance directives within the medical record, and (6) postdischarge evaluation of patient for symptom assessment and treatment adherence within 72 hours of discharge (this can occur by phone, scheduled office visit, or home visit)

An older adult patient who had a mitral valve replacement with a mechanical valve is taking warfarin. What should the nurse include in discharge teaching? a. Use of daily aspirin for anticoagulation. b. Correct method for taking the radial pulse. c. Need for frequent laboratory blood testing. d. Plan to avoid any physical activity for 1 month.

ANS: C Anticoagulation with warfarin (Coumadin) is needed for a patient with mechanical valves to prevent clotting on the valve. This will require frequent international normalized ratio testing. Daily aspirin use will not be effective in reducing the risk for clots on the valve. Monitoring of the radial pulse is not necessary after valve replacement. Patients should resume activities of daily living as tolerated.

Which action by the nurse will determine if therapies ordered for a patient with chronic constrictive pericarditis are effective? a. Assess for the presence of a paradoxical pulse. b. Monitor for changes in the patient's sedimentation rate. c. Assess for the presence of jugular venous distention (JVD). d. Check the electrocardiogram (ECG) for ST segment changes.

ANS: C Because the most common finding on physical examination for a patient with chronic constrictive pericarditis is jugular venous distention, a decrease in JVD indicates improvement. Paradoxical pulse, ST segment ECG changes, and changes in sedimentation rates occur with acute pericarditis but are not expected in chronic constrictive pericarditis.

Which patient will need the nurse to plan discharge teaching about prophylactic antibiotics before dental procedures? a. Patient admitted with a large acute myocardial infarction b. Patient being discharged after an exacerbation of heart failure c. Patient who had a mitral valve replacement with a mechanical valve d. Patient being treated for rheumatic fever after a streptococcal infection

ANS: C Current American Heart Association guidelines recommend the use of prophylactic antibiotics before dental procedures for patients with prosthetic valves to prevent infective endocarditis (IE). The other patients are not at risk for IE.

What nursing assessment finding for a patient with infective endocarditis would be consistent with embolized vegetations from the tricuspid valve? a. Flank pain b. Splenomegaly c. Shortness of breath d. Mental status changes

ANS: C Embolization from the tricuspid valve would cause symptoms of pulmonary embolus. Flank pain, changes in mental status, and splenomegaly would be associated with embolization from the left-sided valves.

A 21-yr-old woman is scheduled for percutaneous transluminal balloon valvuloplasty to treat mitral stenosis. Which information should the nurse include when explaining the advantages of valvuloplasty over valve replacement to the patient? a. Biologic valves will require immunosuppressive drugs after surgery. b. Mechanical mitral valves need to be replaced sooner than biologic valves. c. Lifelong anticoagulant therapy is needed after mechanical valve replacement. d. Ongoing cardiac care by a health care provider is not necessary after valvuloplasty.

ANS: C Long-term anticoagulation therapy is needed after mechanical valve replacement, and this would restrict decisions about career and childbearing in this patient. Mechanical valves are durable and last longer than biologic valves. All valve repair procedures are palliative, not curative, and require lifelong health care. Biologic valves do not activate the immune system and immunosuppressive therapy is not needed.

The nurse is assessing a patient with myocarditis before giving a scheduled dose of digoxin (Lanoxin). Which finding is most important for the nurse to communicate to the health care provider? a. Fatigue b. Leukocytosis c. Irregular pulse d. Generalized myalgia

ANS: C Myocarditis predisposes the heart to digoxin-associated dysrhythmias and toxicity. The other findings are common symptoms of myocarditis and there is no urgent need to report these.

Which statement by a 23-yr-old patient who has mitral valve prolapse (MVP) without valvular regurgitation indicates that discharge teaching has been effective? a. "I will take antibiotics before any dental appointments." b. "I will limit physical activity to avoid stressing the heart." c. "I should avoid over-the-counter drugs that contain stimulants." d. "I should take an aspirin a day to prevent clots from forming on the valve."

ANS: C Patients with MVP should avoid using stimulant drugs because they may exacerbate symptoms. Daily aspirin and restricted physical activity are not needed by patients with mild MVP. Antibiotic prophylaxis is needed for patients with MVP with regurgitation but will not be necessary for this patient.

The nurse is admitting a patient with possible rheumatic fever. Which question on the admission health history focuses on a pertinent risk factor for rheumatic fever? a. "Do you use any illegal IV drugs?" b. "Have you ever injured your chest?" c. "Have you had a recent sore throat?" d. "Do you have a family history of heart disease?"

ANS: C Rheumatic fever occurs because of an abnormal immune response to a streptococcal infection. Although illicit IV drug use should be discussed with the patient before discharge, it is not a risk factor for rheumatic fever, and it would not be as pertinent when admitting the patient. Family history is not a risk factor for rheumatic fever. Chest injury would cause musculoskeletal chest pain rather than rheumatic fever.

Which finding by the nurse assessing a patient with acute pericarditis should be reported immediately to the health care provider? a. Pulsus paradoxus 8 mm Hg b. Blood pressure (BP) of 168/94 mm Hg c. Jugular venous distention (JVD) to jaw level d. Level 6 (0 to 10 scale) chest pain with a deep breath

ANS: C The JVD indicates that the patient may have developed cardiac tamponade and may need rapid intervention to maintain adequate cardiac output. Hypertension would not be associated with complications of pericarditis, and the BP is not high enough to indicate that there is any immediate need to call the health care provider. A pulsus paradoxus of 8 mm Hg is normal. Level 6/10 chest pain should be treated but is not unusual with pericarditis.

A patient recovering from heart surgery develops pericarditis and complains of level 6 (0 to 10 scale) chest pain with deep breathing. Which ordered PRN medication will be the most appropriate for the nurse to give? a. Fentanyl 1 mg IV b. IV morphine sulfate 4 mg c. Oral ibuprofen (Motrin) 600 mg d. Oral acetaminophen (Tylenol) 650 mg

ANS: C The pain associated with pericarditis is caused by inflammation, so nonsteroidal antiinflammatory drugs (NSAIDs) (e.g., ibuprofen) are most effective. Opioid analgesics are usually not used for the pain associated with pericarditis.

A patient with rheumatic fever has subcutaneous nodules, erythema marginatum, and polyarthritis. The patient reports that joint discomfort prevents favorite activities such as taking a daily walk and sewing. What problem should be the focus of nursing interventions? a. Social isolation b. General anxiety c. Activity intolerance d. Altered body image

ANS: C The patient's joint pain will lead to difficulty with activity. Although acute joint pain will be a problem for this patient, joint inflammation is a temporary clinical manifestation of rheumatic fever and is not associated with permanent joint changes. This patient did not provide any data to support a problem with social isolation, anxiety, or altered body image.

The nurse is obtaining a health history from a 24-yr-old patient with hypertrophic cardiomyopathy (CMP). Which information obtained by the nurse is most important in Planning care? a. The patient had a recent upper respiratory infection. b. The patient has a family history of coronary artery disease. c. The patient reports using cocaine "a few times" as a teenager. d. The patient's 29-yr-old brother died from a sudden cardiac arrest.

ANS: D About half of all cases of hypertrophic CMP have a genetic basis, and it is the most common cause of sudden cardiac death in otherwise healthy young people. The information about the patient's brother will be helpful in planning care (e.g., an automatic implantable cardioverter-defibrillator [AICD]) for the patient and in counseling other family members. The patient should be counseled against the use of stimulant drugs, but the limited past history indicates that the patient is not currently at risk for cocaine use. Viral infections and CAD are risk factors for dilated cardiomyopathy but not for hypertrophic CMP.

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 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.

Which statement by a patient with restrictive cardiomyopathy indicates that the nurse's discharge teaching about self-management has been effective? a. "I will avoid taking aspirin or other antiinflammatory drugs." b. "I can restart my exercise program that includes hiking and biking." c. "I will need to limit my intake of salt and fluids even in hot weather." d. "I will take antibiotics before my teeth are cleaned at the dental office."

ANS: D Patients with restrictive cardiomyopathy are at risk for infective endocarditis and should use prophylactic antibiotics for any procedure that may cause bacteremia. The other statements indicate a need for more teaching by the nurse. Dehydration and vigorous exercise impair ventricular filling in patients with restrictive cardiomyopathy. There is no need to avoid salt (unless ordered), aspirin, or nonsteroidal antiinflammatory drugs.

A patient admitted with acute dyspnea is newly diagnosed with dilated cardiomyopathy. Which information will the nurse plan to teach the patient? a. A heart transplant should be scheduled as soon as possible. b. Elevating the legs above the heart will help relieve dyspnea. c. Careful compliance with diet and medications will prevent heart failure. d. Notify the health care provider about symptoms such as shortness of breath.

ANS: D The patient should be instructed to notify the health care provider about any worsening of heart failure symptoms. Because dilated cardiomyopathy does not respond well to therapy, even patients with good compliance with therapy may have recurrent episodes of heart failure. Elevation of the legs above the heart will worsen symptoms (although this approach is appropriate for a patient with hypertrophic cardiomyopathy). The patient with terminal or end-stage cardiomyopathy may consider heart transplantation.

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.

Which action could the nurse delegate to unlicensed assistive personnel (UAP) trained as electrocardiogram (ECG) technicians working on the cardiac unit? a. Select the best lead for monitoring a patient with an admission diagnosis of Dressler syndrome. b. Obtain a list of herbal medications used at home while admitting a new patient with pericarditis. c. Teach about the need to monitor the weight daily for a patient who has hypertrophic cardiomyopathy. d. Watch the heart monitor for changes in rhythm while a patient who had a valve replacement ambulates.

ANS: D Under the supervision of registered nurses (RNs), UAPs check the patient's cardiac monitor and obtain information about changes in heart rate and rhythm with exercise. Teaching and obtaining information about home medications (prescribed or complementary) and selecting the best leads for monitoring patients require more critical thinking and should be done by the RN.

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."

b. "Blood clots form more easily in artificial replacement valves."

The home health nurse is visiting a 30-yr-old patient recovering from rheumatic fever without carditis. Which statement by the patient indicates a need for further teaching? a. "I will need prophylactic antibiotic therapy for 5 years." b. "I can take aspirin or ibuprofen to relieve my joint pain." c. "I will be immune to future episodes of rheumatic fever after this infection." d. "I should call the health care provider if I am fatigued or have difficulty breathing."

c. "I will be immune to future episodes of rheumatic fever after this infection."

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."

d. "Weigh yourself daily while wearing the same amount of clothing."

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.

Two days after an acute myocardial infarction (MI), a patient reports stabbing chest pain that increases with a deep breath. Which action will the nurse take first? a. Auscultate the heart sounds. b. Check the patient's temperature. c. Give PRN acetaminophen (Tylenol). d. Notify the patient's health care provider.

ANS: A The patient's clinical manifestations and history are consistent with pericarditis, and the first action by the nurse should be to listen for a pericardial friction rub. Checking the temperature and notifying the health care provider are also appropriate actions but would not be done before listening for a rub. Acetaminophen (Tylenol) is not effective for pericarditis pain. An analgesic would not be given before assessment of a new symptom.

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.

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 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 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.

A nurse prepares to discharge a client who has heart failure. Which questions would the nurse ask to ensure this client's safety prior to discharging home? (Select all that apply.) a. "Are your bedroom and bathroom on the first floor?" b. "What social support do you have at home?" c. "Will you be able to afford your oxygen therapy?" d. "What spiritual beliefs may impact your recovery?" e. "Are you able to accurately weigh yourself at home?"

ANS: A,B,D To ensure safety upon discharge, the nurse would assess for structural barriers to functional ability, such as stairs. The nurse would also assess the client's available social support, which may include family, friends, and home health services. The client's beliefs about and ability to adhere to medication and treatments, including daily weights, would also be reviewed. The other questions do not specifically address the client's safety upon discharge.

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 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 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.

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 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 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.

Which action should the nurse include in a community health program to decrease the incidence of rheumatic fever? a. Vaccinate high-risk groups in the community with streptococcal vaccine. b. Teach community members to seek treatment for streptococcal pharyngitis. c. Teach about the importance of monitoring temperature when sore throats occur. d. Teach about prophylactic antibiotics to those with a family history of rheumatic fever.

ANS: B The incidence of rheumatic fever is decreased by treatment of streptococcal infections with antibiotics. Family history is not a risk factor for rheumatic fever. There is no immunization that is effective in decreasing the incidence of rheumatic fever. Teaching about monitoring temperature will not decrease the incidence of rheumatic fever.

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 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.

The nurse obtains a health history from an older adult with a prosthetic mitral valve who has symptoms of infective endocarditis (IE). Which question by the nurse helps identify a risk factor for IE? a. "Do you have a history of a heart attack?" b. "Is there a family history of endocarditis?" c. "Have you had any recent immunizations?" d. "Have you had dental work done recently?"

ANS: D Dental procedures place the patient with a prosthetic mitral valve at risk for IE. Myocardial infarction, immunizations, and a family history of endocarditis are not risk factors for IE.

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 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."

a. "Avoid using salt substitutes." 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 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?"

b. "Are you still able to walk upstairs without fatigue?" 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 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."

b. "My shoes fit really tight lately."

A patient has pain due to acute pericarditis. What is an appropriate nursing intervention for this problem? a. Teach the patient to take deep, slow breaths to control the pain. b. Force fluids to 3000 mL/day to decrease fever and inflammation. c. Place the patient in Fowler's position, leaning forward on the table. d. Provide a fresh ice bag every hour for the patient to place on the chest.

c. Place the patient in Fowler's position, leaning forward on the table.
