A
A patient has been taking digoxin [Lanoxin] 0.25 mg, and furosemide [Lasix] 40 mg, daily.Upon routine assessment by the nurse, the patient states, "I see yellow halos around the lights."

A
A nurse is discussing heart failure with a group of nursing students. Which statement by a student reflects an understanding of how compensatory mechanisms can compound existing problems in patients with heart failure? a."An increase in arteriolar tone to improve tissue perfusion can decrease resistance." b."An increase in contractility to increase cardiac output can cause pulmonary edema." c."When the heart rate increases to increase cardiac output, it can prevent adequate filling of the ventricles." d."When venous tone increases to increase ventricular filling, an increase in arterial pressure occurs."
C
A patient is taking enalapril [Vasotec]. The nurse understands that patients taking this type of drug for heart failure need to be monitored carefully for: a.hypernatremia. b.hypertension. c.hyperkalemia. d.hypokalemia.
C
A patient is recovering from a myocardial infarction but does not have symptoms of heart failure. The nurse will expect to teach this patient about: a.ACE inhibitors and beta blockers. b.biventricular pacemakers. c.dietary supplements and exercise. d.diuretics and digoxin
A
A patient newly diagnosed with heart failure is admitted to the hospital. The nurse notes a pulse of 90 beats per minute. The nurse will observe this patient closely for: a.decreased urine output. b.increased blood pressure. c.jugular vein distension. d.shortness of breath.
A
A patient with Stage C heart failure (HF) who has been taking an ACE inhibitor, a beta blocker, and a diuretic begins to have increased dyspnea, weight gain, and decreased urine output. The provider orders spironolactone [Aldactone]. The nurse will instruct the patient to: a.avoid potassium supplements. b.monitor for a decreased heart rate. c.take extra fluids. d.use a salt substitute instead of salt.
A
A patient with heart failure who has been given digoxin [Lanoxin] daily for a week complains of nausea. Before giving the next dose, the nurse will: a.assess the heart rate (HR) and give the dose if the HR is greater than 60 beats per minute. b.contact the provider to report digoxin toxicity. c.request an order for a decreased dose of digoxin. d.review the serum electrolyte values and withhold the dose if the potassium level is greater than 3.5 mEq/L.
A
A patient with volume overload begins taking a thiazide diuretic. The nurse will tell the patient to expect which outcome when taking this drug? a.Improved exercise tolerance b.Increased cardiac output c.Prevention of cardiac remodeling d.Prolonged survival
A
The potassium-sparing diuretic spironolactone [Aldactone] prolongs survival and improves heart failure symptoms by which mechanism?a.Blocking aldosterone receptors b.Increasing diuresis c.Reducing venous pressure d.Reducing afterload
A
A patient with heart failure who has been taking an ACE inhibitor, a thiazide diuretic, and a beta blocker for several months comes to the clinic for evaluation. As part of the on going assessment of this patient, the nurse will expect the provider to evaluate: a.complete blood count. b.ejection fraction. c.maximal exercise capacity. d.serum electrolyte levels.
D
A nurse is preparing to administer digoxin [Lanoxin] to a patient. The patient's heart rate is 62beats per minute, and the blood pressure is 120/60 mm Hg. The last serum electrolyte value showed a potassium level of 5.2 mEq/L. What will the nurse do? a.Contact the provider to request an increased dose of digoxin. b.Give the dose of digoxin and notify the provider of the potassium level. c.Request an order for a diuretic. d.Withhold the dose and notify the provider of the heart rate.
B
A patient asks a nurse why he cannot use digoxin [Lanoxin] for his heart failure, because both of his parents used it for HF. The nurse will explain that digoxin is not the first-line therapy for which reason?a.It causes tachycardia and increases the cardiac workload. b.It does not correct the underlying pathology of heart failure. c.It has a wide therapeutic range that makes dosing difficult. d.It may actually shorten the patient's life expectancy
B
An 88-year-old patient with heart failure has progressed to Stage D and is hospitalized for the third time in a month. The nurse will expect to discuss which topic with the patient's family? a.Antidysrhythmic medications b.End-of-life care c.Heart transplantation d.Implantable mechanical assist devices
B
A patient is taking a thiazide diuretic for hypertension and quinidine to treat a dysrhythmia.The prescriber orders digoxin 0.125 mg to improve this patient's cardiac output. The nurse should contact the provider to request: a.adding spironolactone [Aldactone]. b.reducing the dose of digoxin. c.discontinuing the quinidine. d.giving potassium supplements
C
A patient with chronic hypertension is admitted to the hospital. During the admission assessment, the nurse notes a heart rate of 96 beats per minute, a blood pressure of 150/90 mmHg, bibasilar crackles, 2+ pitting edema of the ankles, and distension of the jugular veins. The nurse will contact the provider to request an order for which medication? a.ACE inhibitor b.Digoxin [Lanoxin] c.Furosemide [Lasix] d.Spironolactone [Aldactone]
C
A patient with heart failure who takes a thiazide diuretic and digoxin [Lanoxin] is admitted for shortness of breath. The patient's heart rate is 66 beats per minute, and the blood pressure is130/88 mm Hg. The serum potassium level is 3.8 mEq/L, and the digoxin level is 0.8 ng/mL.The nurse admitting this patient understands that the patient: a.has digoxin toxicity. b.is showing signs of renal failure. c.is experiencing worsening of the disease. d.needs a potassium-sparing diuretic
C
A nurse prepares to administer a scheduled dose of digoxin. The nurse finds a new laboratoryreport showing a plasma digoxin level of 0.7 ng/mL. What action should the nurse take? a.Withhold the drug for an hour and reassess the level. b.Withhold the drug and notify the prescriber immediately. c.Administer Digibind to counteract the toxicity. d.Check the patient's apical pulse, and if it is within a safe range, administer thedigoxin.
