Chapter 24 : Heart Failure Drugs Questions
Question 1 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: D
Rationale: Bran, in large amounts, may decrease the absorption of oral digitalis drugs. The other foods do not affect digoxin levels.
Question 2 of 5
In assessing a patient before administration of a cardiac glycoside, the nurse knows that which lab result can increase the toxicity of the drug?
Correct Answer: A
Rationale: Hypokalemia increases the chance of digitalis toxicity. The other levels listed are incorrect.
Question 3 of 5
The nurse administering the phosphodiesterase inhibitor milrinone recognizes that this drug will have a positive inotropic effect. Which result reflects this effect?
Correct Answer: C
Rationale: Positive inotropic drugs increase myocardial contractility, thus increasing the force of cardiac contractions. Positive chronotropic drugs increase the heart rate. Positive dromotropic drugs increase the conduction of electrical impulses across the heart. Blood vessel dilation is not affected.
Question 4 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 5 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.
