Chapter 22: Antihypertensive Drugs MULTIPLE CHOICE 1. A patient has a new order for the adrenergic drug doxazosin (Cardura). When providing
education about this drug, the nurse will include which instructions? a. “Weigh yourself daily, and report any weight loss to your prescriber.” b. “Increase your potassium intake by eating more bananas and apricots.” c. “The impaired taste associated with this medication usually goes away in 2 to 3 weeks.” d. “Be sure to lie down after taking the first dose, because first-dose hypotension may make you dizzy.” ANS: D
A patient who is starting doxazosin should take the first dose while lying down because there is a first-dose hypotensive effect with this medication. The other options are incorrect.

A patient with severe liver disease is receiving the angiotensin-converting enzyme (ACE)
inhibitor, captopril (Capoten). The nurse is aware that the advantage of this drug for this patient is which characteristic? a. Captopril rarely causes first-dose hypotensive effects. b. Captopril has little effect on electrolyte levels. c. Captopril is a prodrug and is metabolized by the liver before becoming active. d. Captopril is not a prodrug and does not need to be metabolized by the liver before becoming active. ANS: D
A prodrug relies on a functioning liver to be converted to its active form. Captopril is not a prodrug, and therefore it would be safer for the patient with liver dysfunction.

During a follow-up visit, the health care provider examines the fundus of the patient’s eye.
Afterward, the patient asks the nurse, “Why is he looking at my eyes when I have high blood pressure? It does not make sense to me!” What is the best response by the nurse? a. “We need to monitor for drug toxicity.” b. “We must watch for increased intraocular pressure.” c. “The provider is assessing for visual changes that may occur with drug therapy.” d. “The provider is making sure the treatment is effective over the long term.” ANS: D
