Chapter 22 : Antihypertensive Drugs Questions
Question 1 of 5
An older adult patient will be taking a vasodilator for hypertension. Which adverse effect is of most concern for the older adult patient taking this class of drug?
Correct Answer: D
Rationale: The older adult patient is more sensitive to the blood pressure-lowering effects of vasodilators, and consequently experiences more problems with hypotension, dizziness, and syncope. The other options are incorrect.
Question 2 of 5
When teaching a patient about antihypertensive drug therapy, which statements by the nurse are correct?
Correct Answer: A,C,F
Rationale: Keeping a record of weekly blood pressure checks helps to monitor the effectiveness of the therapy. An exercise program may be beneficial but should be confirmed with the prescriber. Therapy is often lifelong, and patients should continue taking the medication even if feeling better to prevent rebound hypertension. Abruptly stopping medication or assuming over-the-counter decongestants are safe can lead to serious complications.
Question 3 of 5
A patient is to receive enalapril 5 mg IV every 6 hours. Each dose is given over 5 minutes. The medication is available in an injectable form, 1.25 mg/mL. Identify how many milliliters of medication will the nurse draw up for each dose.
Correct Answer: 4 mL
Rationale: 1.25 mg : 1 mL :: 5 mg : x mL; (1.25 * x) = (1 * 5); 1.25x = 5; x = 4 mL.
Question 4 of 5
A patient has a new order for the adrenergic drug doxazosin. When providing education about this drug, the nurse will include which instructions?
Correct Answer: D
Rationale: 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.
Question 5 of 5
A patient with severe liver disease is receiving the angiotensin-converting enzyme (ACE) inhibitor, captopril. The nurse is aware that the advantage of this drug for this patient is which characteristic?
Correct Answer: D
Rationale: 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.
