Chapter 24 : Heart Failure Drugs Questions
Question 1 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 2 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 3 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 4 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 5 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.
