ARBs Angiotensin II Receptor Blockers NCLEX Questions (NCLEX EXAM 2022)

1.      You’re teaching a patient about how angiotensin II receptor blockers (ARBs) work. Which statement below BEST describes how these medications work on the body?

A.     “They prevent Angiotensin II Type I Receptors from binding with Angiotensin II.”

B.     “These medications prevent the activation of Angiotensin II Type II Receptors from binding with Angiotensin II.”

C.     “They inhibit angiotensin-converting-enzyme (ACE) from converting an Angiotensin I to Angiotensin II.”

D.     “These medications prevent Angiotensin II Type I Receptors from binding with angiotensin-converting-enzyme (ACE).”

The answer is A. ARBs prevent Angiotensin II Type I Receptors from binding with Angiotensin II. Remember ACE Inhibitors inhibit angiotensin-converting-enzyme (ACE) from converting Angiotensin I to Angiotensin II.

2.      A physician writes a new medication order for a patient who has cardiovascular disease. The medication is an angiotensin II receptor blocker (ARB). What new medication on the patient’s scheduled medication list is an ARB?

A.     Metoprolol

B.     Losartan

C.     Lisinopril

D.     Nicardipine

The answer is B. Remember ARBs end with “SARTAN”. Losartan is an ARB.

3.      A patient who developed a dry, persistent cough while taking an ACE Inhibitor is switched to an angiotensin II receptor blocker (ARB). The patient reports the cough is now gone, but asks you to explain how this medication helped alleviate the cough. What is the correct response?

A.     “ARBs prevent ACE (angiotensin-converting-enzyme) from breaking down bradykinin so a dry, persistent cough is less likely.”
