Answer to Question 1

Ans: C
Feedback:
Losartan is an angiotensin II receptor antagonist, acting to block the angiotensin II receptors. By blocking the angiotensin II receptor, the renin-angiotensin system is stopped and consequently blood pressure is reduced. Drugs such as captopril prevent the conversion of angiotensin I. Losartan does not prevent renin secretion. Losartan does not block aldosterone receptors.

Answer to Question 2

Ans: B
Feedback:
Rebound hypertension will occur in clients when antihypertensives are abruptly discontinued. In rebound hypertension, there is a sudden rise in blood pressure when the antihypertensives are withheld. Orthostatic hypotension, anginal attacks, and breathing difficulty are the adverse reactions associated with antihypertensive drug usage and may not occur on stopping the drug.
