Chapter 24 : Heart Failure Drugs Questions
Question 1 of 5
The nurse notes in a patient's medical record that ivabradine has been ordered. Based on this order, the nurse interprets that the patient has which disorder?
Correct Answer: C
Rationale: Ivabradine is indicated for the treatment of stable, symptomatic heart failure with an ejection fraction of 35% or less. A potential adverse effect is atrial fibrillation. The other options are not indications for ivabradine.
Question 2 of 5
When administering digoxin immune Fab to a patient with severe digoxin toxicity, the nurse knows that each vial can bind with how much digoxin?
Correct Answer: A
Rationale: Each vial of digoxin immune Fab (Digifab) can bind approximately 0.5 mg of digoxin, helping to neutralize the drug in cases of severe toxicity.
Question 3 of 5
A patient in the intensive care unit is on a dobutamine infusion and is to receive furosemide 40 mg IV now. What is the nurse's best action to administer the furosemide?
Correct Answer: C
Rationale: Furosemide must not be injected into an intravenous line with milrinone because it will precipitate immediately. The infusion must not be stopped because of the patient's condition. A separate line will be needed. The other options are incorrect.
Question 4 of 5
When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use of digoxin immune Fab?
Correct Answer: B,D,E
Rationale: Clinical situations that would require the use of digoxin immune Fab in a patient with digoxin toxicity include serum potassium level above 5 mEq/L, severe sinus bradycardia that does not respond to cardiac pacing, or an overdose of more than 10 mg of digoxin. Seeing colorful halos around lights, nausea, anorexia, fatigue, and headaches are potential adverse effects of digoxin therapy but are not necessarily reasons for digoxin immune Fab treatment.
Question 5 of 5
Which drug classes are considered first-line treatment for heart failure?
Correct Answer: A,B,D
Rationale: ACE inhibitors, ARBs, and certain beta blockers are now considered the first-line treatments for heart failure. Digoxin is used when the first-line treatments are not successful; nesiritide is considered a last-resort treatment.
