1. A patient with hypertension is prescribed a medication that inhibits the

renin-angiotensin-aldosterone system (RAAS). Which of the following

outcomes should the nurse expect?

 A) Increased blood pressure

 B) Decreased blood pressure

 C) Increased potassium levels

 D) Decreased urine output

 Answer: B) Decreased blood pressure

 Rationale: Inhibiting the RAAS leads to vasodilation and decreased

blood volume, resulting in lowered blood pressure.

2. A nursing student is asked to identify the primary function of

angiotensin II. Which answer is correct?

 A) It reduces blood pressure.

 B) It increases glomerular filtration rate.

 C) It promotes sodium and water reabsorption.

 D) It stimulates the parasympathetic nervous system.

 Answer: C) It promotes sodium and water reabsorption.

 Rationale: Angiotensin II causes vasoconstriction and stimulates

aldosterone release, promoting sodium and water reabsorption, which

increases blood volume and pressure.

3. During a case study discussion, a student nurse learns that aldosterone

has been elevated in a patient. What should be the expected effect on urine

output?

 A) Increased urine output due to diuresis

 B) Decreased urine output due to antidiuresis

 C) No change in urine output

 D) Fluctuating urine output depending on fluid intake

 Answer: B) Decreased urine output due to antidiuresis

 Rationale: Aldosterone promotes sodium and water reabsorption in the

kidneys, leading to decreased urine output.

4. When teaching about the RAAS, which organ should the nurse

emphasize as the initial signal trigger?

 A) Heart

 B) Kidneys
