MSU MS2 test 3 - Heart Failure
Terms in this set (26)
While assessing a 68-year-old with ascites, the nurse also notes jugular venous distention (JVD) with the head of the patient's bed elevated 45 degrees. The nurse knows this finding indicates
a. decreased fluid volume.
b. jugular vein atherosclerosis.
c. increased right atrial pressure.
d. incompetent jugular vein valves.
The jugular veins empty into the superior vena cava and then into the right atrium, so JVD with the patient sitting at a 45-degree angle reflects increased right atrial pressure. JVD is an indicator of excessive fluid volume (increased preload), not decreased fluid volume. JVD is not caused by incompetent jugular vein valves or atherosclerosis
The nurse is caring for a patient who is receiving IV furosemide (Lasix) and morphine for the treatment of acute decompensated heart failure (ADHF) with severe orthopnea. Which clinical finding is the best indicator that the treatment has been effective?
a. Weight loss of 2 pounds in 24 hours
b. Hourly urine output greater than 60 mL
c. Reduction in patient complaints of chest pain
d. Reduced dyspnea with the head of bed at 30 degrees
Because the patient's major clinical manifestation of ADHF is orthopnea (caused by the presence of fluid in the alveoli), the best indicator that the medications are effective is a decrease in dyspnea with the head of the bed at 30 degrees. The other assessment data also may indicate that diuresis or improvement in cardiac output has occurred, but are not as specific to evaluating this patient's response
Which topic will the nurse plan to include in discharge teaching for a patient with systolic heart failure and an ejection fraction of 33%?
a. Need to begin an aerobic exercise program several times weekly
b. Use of salt substitutes to replace table salt when cooking and at the table
c. Benefits and side effects of angiotensin-converting enzyme (ACE) inhibitors
d. Importance of making an annual appointment with the primary care provider
The core measures for the treatment of heart failure established by The Joint Commission indicate that patients with an ejection fraction (EF) <40% receive an ACE inhibitor to decrease the progression of heart failure. Aerobic exercise may not be appropriate for a patient with this level of heart failure, salt substitutes are not usually recommended because of the risk of hyperkalemia, and the patient will need to see the primary care provider more frequently than annually
IV sodium nitroprusside (Nipride) is ordered for a patient with acute pulmonary edema. During the first hours of administration, the nurse will need to titrate the nitroprusside rate if the patient develops
a. ventricular ectopy.
b. a dry, hacking cough.
c. a systolic BP <90 mm Hg.
d. a heart rate <50 beats/minute.
Sodium nitroprusside is a potent vasodilator, and the major adverse effect is severe hypotension. Coughing and bradycardia are not adverse effects of this medication. Nitroprusside does not cause increased ventricular ectopy
A patient who has chronic heart failure tells the nurse, "I was fine when I went to bed, but I woke up in the middle of the night feeling like I was suffocating!" The nurse will document this assessment finding as
b. pulsus alternans.
c. paroxysmal nocturnal dyspnea.
d. acute bilateral pleural effusion.
Paroxysmal nocturnal dyspnea is caused by the reabsorption of fluid from dependent body areas when the patient is sleeping and is characterized by waking up suddenly with the feeling of suffocation. Pulsus alternans is the alternation of strong and weak peripheral pulses during palpation. Orthopnea indicates that the patient is unable to lie flat because of dyspnea. Pleural effusions develop over a longer time period
During a visit to a 78-year-old with chronic heart failure, the home care nurse finds that the patient has ankle edema, a 2-kg weight gain over the past 2 days, and complains of "feeling too tired to get out of bed." Based on these data, the best nursing diagnosis for the patient is
a. activity intolerance related to fatigue.
b. disturbed body image related to weight gain.
c. impaired skin integrity related to ankle edema.
d. impaired gas exchange related to dyspnea on exertion.
The patient's statement supports the diagnosis of activity intolerance. There are no data to support the other diagnoses, although the nurse will need to assess for other patient problems
The nurse working on the heart failure unit knows that teaching an older female patient with newly diagnosed heart failure is effective when the patient states that
a. she will take furosemide (Lasix) every day at bedtime.
b. the nitroglycerin patch is applied when any chest pain develops.
c. she will call the clinic if her weight goes from 124 to 128 pounds in a week.
d. an additional pillow can help her sleep if she is feeling short of breath at night.
Teaching for a patient with heart failure includes information about the need to weigh daily and notify the health care provider about an increase of 3 pounds in 2 days or 3 to 5 pounds in a week. Nitroglycerin patches are used primarily to reduce preload (not to prevent chest pain) in patients with heart failure and should be used daily, not on an "as needed" basis. Diuretics should be taken earlier in the day to avoid nocturia and sleep disturbance. The patient should call the clinic if increased orthopnea develops, rather than just compensating by further elevating the head of the bed
When teaching the patient with newly diagnosed heart failure about a 2000-mg sodium diet, the nurse explains that foods to be restricted include
a. canned and frozen fruits.
b. fresh or frozen vegetables.
c. eggs and other high-protein foods.
d. milk, yogurt, and other milk products.
Milk and yogurt naturally contain a significant amount of sodium, and intake of these should be limited for patients on a diet that limits sodium to 2000 mg daily. Other milk products, such as processed cheeses, have very high levels of sodium and are not appropriate for a 2000-mg sodium diet. The other foods listed have minimal levels of sodium and can be eaten without restriction
The nurse plans discharge teaching for a patient with chronic heart failure who has prescriptions for digoxin (Lanoxin) and hydrochlorothiazide (HydroDIURIL). Appropriate instructions for the patient include
a. limit dietary sources of potassium.
b. take the hydrochlorothiazide before bedtime.
c. notify the health care provider if nausea develops.
d. skip the digoxin if the pulse is below 60 beats/minute.
Nausea is an indication of digoxin toxicity and should be reported so that the provider can assess the patient for toxicity and adjust the digoxin dose, if necessary. The patient will need to include potassium-containing foods in the diet to avoid hypokalemia. Patients should be taught to check their pulse daily before taking the digoxin and if the pulse is less than 60, to call their provider before taking the digoxin. Diuretics should be taken early in the day to avoid sleep disruption
While admitting an 82-year-old with acute decompensated heart failure to the hospital, the nurse learns that the patient lives alone and sometimes confuses the "water pill" with the "heart pill." When planning for the patient's discharge the nurse will facilitate a
a. consult with a psychologist.
b. transfer to a long-term care facility.
c. referral to a home health care agency.
d. arrangements for around-the-clock care.
The data about the patient suggest that assistance in developing a system for taking medications correctly at home is needed. A home health nurse will assess the patient's home situation and help the patient develop a method for taking the two medications as directed. There is no evidence that the patient requires services such as a psychologist consult, long-term care, or around-the-clock home care
Following an acute myocardial infarction, a previously healthy 63-year-old develops clinical manifestations of heart failure. The nurse anticipates discharge teaching will include information about
a. digitalis preparations.
b. b-adrenergic blockers.
c. calcium channel blockers.
d. angiotensin-converting enzyme (ACE) inhibitors.
ACE inhibitor therapy is currently recommended to prevent the development of heart failure in patients who have had a myocardial infarction and as a first-line therapy for patients with chronic heart failure. Digoxin therapy for heart failure is no longer considered a first-line measure, and digoxin is added to the treatment protocol when therapy with other medications such as ACE-inhibitors, diuretics, and b-adrenergic blockers is insufficient. Calcium channel blockers are not generally used in the treatment of heart failure. The b-adrenergic blockers are not used as initial therapy for new onset heart failure
A 53-year-old patient with Stage D heart failure and type 2 diabetes asks the nurse whether heart transplant is a possible therapy. Which response by the nurse is most appropriate?
a. "Because you have diabetes, you would not be a candidate for a heart transplant."
b. "The choice of a patient for a heart transplant depends on many different factors."
c. "Your heart failure has not reached the stage in which heart transplants are needed."
d. "People who have heart transplants are at risk for multiple complications after surgery."
Indications for a heart transplant include end-stage heart failure (Stage D), but other factors such as coping skills, family support, and patient motivation to follow the rigorous posttransplant regimen are also considered. Diabetic patients who have well-controlled blood glucose levels may be candidates for heart transplant. Although heart transplants can be associated with many complications, this response does not address the patient's question
Which diagnostic test will be most useful to the nurse in determining whether a patient admitted with acute shortness of breath has heart failure?
a. Serum troponin
b. Arterial blood gases
c. B-type natriuretic peptide
d. 12-lead electrocardiogram
B-type natriuretic peptide (BNP) is secreted when ventricular pressures increase, as they do with heart failure. Elevated BNP indicates a probable or very probable diagnosis of heart failure. A twelve-lead electrocardiogram, arterial blood gases, and troponin may also be used in determining the causes or effects of heart failure but are not as clearly diagnostic of heart failure as BNP
Which action should the nurse include in the plan of care when caring for a patient admitted with acute decompensated heart failure (ADHF) who is receiving nesiritide (Natrecor)?
a. Monitor blood pressure frequently.
b. Encourage patient to ambulate in room.
c. Titrate nesiritide slowly before stopping.
d. Teach patient about home use of the drug.
Nesiritide is a potent arterial and venous dilator, and the major adverse effect is hypotension. Because the patient is likely to have orthostatic hypotension, the patient should not be encouraged to ambulate. Nesiritide does not require titration and is used for ADHF but not in a home setting
A patient with heart failure has a new order for captopril (Capoten) 12.5 mg PO. After administering the first dose and teaching the patient about the drug, which statement by the patient indicates that teaching has been effective?
a. "I will be sure to take the medication with food."
b. "I will need to eat more potassium-rich foods in my diet."
c. "I will call for help when I need to get up to use the bathroom."
d. "I will expect to feel more short of breath for the next few days."
Captopril can cause hypotension, especially after the initial dose, so it is important that the patient not get up out of bed without assistance until the nurse has had a chance to evaluate the effect of the first dose. The angiotensin-converting enzyme (ACE) inhibitors are potassium sparing, and the nurse should not teach the patient to purposely increase sources of dietary potassium. Increased shortness of breath is expected with the initiation of b-adrenergic blocker therapy for heart failure, not for ACE inhibitor therapy. ACE inhibitors are best absorbed when taken an hour before eating
A patient who has just been admitted with pulmonary edema is scheduled to receive the following medications. Which medication should the nurse question before giving?
a. Furosemide (Lasix) 60 mg
b. Captopril (Capoten) 25 mg
c. Digoxin (Lanoxin) 0.125 mg
d. Carvedilol (Coreg) 3.125 mg
Although carvedilol is appropriate for the treatment of chronic heart failure, it is not used for patients with acute decompensated heart failure (ADHF) because of the risk of worsening the heart failure. The other medications are appropriate for the patient with ADHF
A patient with a history of chronic heart failure is admitted to the emergency department (ED) with severe dyspnea and a dry, hacking cough. Which action should the nurse do first?
a. Auscultate the abdomen.
b. Check the capillary refill.
c. Auscultate the breath sounds.
d. Assess the level of orientation.
This patient's severe dyspnea and cough indicate that acute decompensated heart failure (ADHF) is occurring. ADHF usually manifests as pulmonary edema, which should be detected and treated immediately to prevent ongoing hypoxemia and cardiac/respiratory arrest. The other assessments will provide useful data about the patient's volume status and also should be accomplished rapidly, but detection (and treatment) of pulmonary complications is the priority
A patient with chronic heart failure who is taking a diuretic and an angiotensin-converting enzyme (ACE) inhibitor and who is on a low-sodium diet tells the home health nurse about a 5-pound weight gain in the last 3 days. The nurse's priority action will be to
a. have the patient recall the dietary intake for the last 3 days.
b. ask the patient about the use of the prescribed medications.
c. assess the patient for clinical manifestations of acute heart failure.
d. teach the patient about the importance of restricting dietary sodium.
The 5-pound weight gain over 3 days indicates that the patient's chronic heart failure may be worsening. It is important that the patient be assessed immediately for other clinical manifestations of decompensation, such as lung crackles. A dietary recall to detect hidden sodium in the diet, reinforcement of sodium restrictions, and assessment of medication compliance may be appropriate interventions but are not the first nursing actions indicated.
A patient in the intensive care unit with acute decompensated heart failure (ADHF) complains of severe dyspnea and is anxious, tachypneic, and tachycardic. All of the following medications have been ordered for the patient. The nurse's priority action will be to
a. give IV morphine sulfate 4 mg.
b. give IV diazepam (Valium) 2.5 mg.
c. increase nitroglycerin (Tridil) infusion by 5 mcg/min.
d. increase dopamine (Intropin) infusion by 2 mcg/kg/min.
Morphine improves alveolar gas exchange, improves cardiac output by reducing ventricular preload and afterload, decreases anxiety, and assists in reducing the subjective feeling of dyspnea. Diazepam may decrease patient anxiety, but it will not improve the cardiac output or gas exchange. Increasing the dopamine may improve cardiac output, but it will also increase the heart rate and myocardial oxygen consumption. Nitroglycerin will improve cardiac output and may be appropriate for this patient, but it will not directly reduce anxiety and will not act as quickly as morphine to decrease dyspnea
After receiving change-of-shift report on a heart failure unit, which patient should the nurse assess first?
a. A patient who is cool and clammy, with new-onset confusion and restlessness
b. A patient who has crackles bilaterally in the lung bases and is receiving oxygen.
c. A patient who had dizziness after receiving the first dose of captopril (Capoten)
d. A patient who is receiving IV nesiritide (Natrecor) and has a blood pressure of 100/62
The patient who has "wet-cold" clinical manifestations of heart failure is perfusing inadequately and needs rapid assessment and changes in management. The other patients also should be assessed as quickly as possible but do not have indications of severe decreases in tissue perfusion.
Which assessment finding in a patient admitted with acute decompensated heart failure (ADHF) requires the most immediate action by the nurse?
a. Oxygen saturation of 88%
b. Weight gain of 1 kg (2.2 lb)
c. Heart rate of 106 beats/minute
d. Urine output of 50 mL over 2 hours
A decrease in oxygen saturation to less than 92% indicates hypoxemia. The nurse should administer supplemental oxygen immediately to the patient. An increase in apical pulse rate, 1-kg weight gain, and decreases in urine output also indicate worsening heart failure and require nursing actions, but the low oxygen saturation rate requires the most immediate nursing action
A patient has recently started on digoxin (Lanoxin) in addition to furosemide (Lasix) and captopril (Capoten) for the management of heart failure. Which assessment finding by the home health nurse is a priority to communicate to the health care provider?
a. Presence of 1 to 2+ edema in the feet and ankles
b. Palpable liver edge 2 cm below the ribs on the right side
c. Serum potassium level 3.0 mEq/L after 1 week of therapy
d. Weight increase from 120 pounds to 122 pounds over 3 days
Hypokalemia can predispose the patient to life-threatening dysrhythmias (e.g., premature ventricular contractions), and potentiate the actions of digoxin and increase the risk for digoxin toxicity, which can also cause life-threatening dysrhythmias. The other data indicate that the patient's heart failure requires more effective therapies, but they do not require nursing action as rapidly as the low serum potassium level
An outpatient who has chronic heart failure returns to the clinic after 2 weeks of therapy with metoprolol (Toprol XL). Which assessment finding is most important for the nurse to report to the health care provider?
a. 2+ pedal edema
b. Heart rate of 56 beats/minute
c. Blood pressure (BP) of 88/42 mm Hg
d. Complaints of fatigue
The patient's BP indicates that the dose of metoprolol may need to be decreased because of hypotension. Bradycardia is a frequent adverse effect of b-adrenergic blockade, but the rate of 56 is not unusual with â-adrenergic blocker therapy. b-Adrenergic blockade initially will worsen symptoms of heart failure in many patients, and patients should be taught that some increase in symptoms, such as fatigue and edema, is expected during the initiation of therapy with this class of drugs
A patient who is receiving dobutamine (Dobutrex) for the treatment of acute decompensated heart failure (ADHF) has the following nursing interventions included in the plan of care. Which action will be most appropriate for the registered nurse (RN) to delegate to an experienced licensed practical/vocational nurse (LPN/LVN)?
a. Assess the IV insertion site for signs of extravasation.
b. Teach the patient the reasons for remaining on bed rest.
c. Monitor the patient's blood pressure and heart rate every hour.
d. Titrate the rate to keep the systolic blood pressure >90 mm Hg.
An experienced LPN/LVN would be able to monitor BP and heart rate and would know to report significant changes to the RN. Teaching patients, making adjustments to the drip rate for vasoactive medications, and monitoring for serious complications such as extravasation require RN level education and scope of practice
After receiving change-of-shift report on a heart failure unit, which patient should the nurse assess first?
a. Patient who is taking carvedilol (Coreg) and has a heart rate of 58
b. Patient who is taking digoxin and has a potassium level of 3.1 mEq/L
c. Patient who is taking isosorbide dinitrate/hydralazine (BiDil) and has a headache
d. Patient who is taking captopril (Capoten) and has a frequent nonproductive cough
The patient's low potassium level increases the risk for digoxin toxicity and potentially fatal dysrhythmias. The nurse should assess the patient for other signs of digoxin toxicity and then notify the health care provider about the potassium level. The other patients also have side effects of their medications, but their symptoms do not indicate potentially life-threatening complications
Based on the Joint Commission Core Measures for patients with heart failure, which topics should the nurse include in the discharge teaching plan for a patient who has been hospitalized with chronic heart failure (select all that apply)?
a. How to take and record daily weight
b. Importance of limiting aerobic exercise
c. Date and time of follow-up appointment
d. Symptoms indicating worsening heart failure
e. Actions and side effects of prescribed medications
ANS: A, C, D, E
The Joint Commission Core Measures state that patients should be taught about prescribed medications, follow-up appointments, weight monitoring, and actions to take for worsening symptoms. Patients with heart failure are encouraged to begin or continue aerobic exercises such as walking, while self-monitoring to avoid excessive fatigue
