## Section 1: Reading (Questions 1–18)
**Passage 1 (Questions 1–5):**
The renin-angiotensin-aldosterone system (RAAS) is a hormone system that regulates blood pressure
and fluid balance. When blood pressure drops, the kidneys release renin. Renin converts
angiotensinogen to angiotensin I, which is then converted to angiotensin II by angiotensin-converting
enzyme (ACE). Angiotensin II causes vasoconstriction and stimulates aldosterone release, leading to
sodium and water retention, which increases blood pressure.
**1.** What triggers the release of renin?
A) High blood pressure
B) Low blood pressure
C) High sodium levels
D) Low potassium levels
💡 RATIONALE – Passage states: "When blood pressure drops, the kidneys release renin."
✔️ ANSWER – B) Low blood pressure
---
**2.** Angiotensin II causes:
A) Vasodilation and decreased blood pressure
B) Vasoconstriction and increased blood pressure
,C) Increased urine output
D) Decreased aldosterone release
💡 RATIONALE – Angiotensin II causes vasoconstriction and stimulates aldosterone release, raising BP.
✔️ ANSWER – B) Vasoconstriction and increased blood pressure
---
**3.** ACE converts:
A) Renin to angiotensinogen
B) Angiotensin I to angiotensin II
C) Angiotensin II to aldosterone
D) Aldosterone to renin
💡 RATIONALE – ACE converts angiotensin I to angiotensin II.
✔️ ANSWER – B) Angiotensin I to angiotensin II
---
**4.** Aldosterone causes:
A) Sodium excretion
B) Sodium and water retention
C) Potassium retention
D) Vasodilation
💡 RATIONALE – Aldosterone increases sodium and water reabsorption (raises BP).
✔️ ANSWER – B) Sodium and water retention
,---
**5.** A medication that blocks ACE would most likely:
A) Increase blood pressure
B) Decrease blood pressure
C) Increase heart rate
D) Have no effect
💡 RATIONALE – ACE inhibitors block angiotensin II formation, causing vasodilation and lower BP.
✔️ ANSWER – B) Decrease blood pressure
---
**Passage 2 (Questions 6–10):**
The nurse is caring for a client with a new diagnosis of heart failure. The provider orders furosemide
(Lasix) 40 mg IV daily, enalapril 5 mg PO daily, and a 2-gram sodium diet. The client's weight is 85 kg. The
nurse notes crackles in the lung bases and +2 pitting edema in the lower extremities.
**6.** Furosemide is a:
A) Beta blocker
B) ACE inhibitor
C) Loop diuretic
D) Calcium channel blocker
💡 RATIONALE – Furosemide (Lasix) is a loop diuretic.
✔️ ANSWER – C) Loop diuretic
---
, **7.** The crackles and edema indicate:
A) Dehydration
B) Fluid overload
C) Infection
D) Kidney failure
💡 RATIONALE – Crackles (pulmonary congestion) and edema = fluid overload in heart failure.
✔️ ANSWER – B) Fluid overload
---
**8.** A 2-gram sodium diet means the client should:
A) Avoid all fluids
B) Limit sodium to 2 grams per day
C) Increase potassium intake
D) Drink 2 liters of water daily
💡 RATIONALE – Sodium restriction reduces fluid retention in heart failure.
✔️ ANSWER – B) Limit sodium to 2 grams per day
---
**9.** Which food is highest in sodium?
A) Fresh apple
B) Canned vegetable soup
C) Brown rice
D) Unsalted almonds
