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
