Chapter 24 : Heart Failure Drugs Questions
Question 1 of 5
A patient has been placed on a milrinone infusion as part of the therapy for end-stage heart failure. What adverse effect of this drug will the nurse watch for when assessing this patient during the infusion?
Correct Answer: D
Rationale: The primary adverse effects seen with milrinone are cardiac dysrhythmias, mainly ventricular. It may also cause hypotension, hypokalemia, and other effects, but not nausea and vomiting.
Question 2 of 5
A patient has a digoxin level of 1.1 ng/mL. Which interpretation by the nurse is correct?
Correct Answer: B
Rationale: The normal therapeutic drug level of digoxin is between 0.5 and 2 ng/mL. The other options are incorrect.
Question 3 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 4 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 5 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.
