## Section 1: Reading (Questions 1–14)
**Passage 1 (Questions 1–5):**
The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin).
The nurse explains that warfarin is an anticoagulant that prevents blood clots. The client should avoid
foods high in vitamin K, such as spinach, kale, and broccoli. The client should report any signs of
bleeding, including bruising, dark stools, or bleeding gums. Regular INR monitoring is required.
**1.** Warfarin is used to:
A) Lower blood pressure
B) Prevent blood clots
C) Reduce pain
D) Lower cholesterol
💡 **RATIONALE** – Warfarin is an anticoagulant that inhibits vitamin K–dependent clotting factors
(II, VII, IX, X) to prevent thrombus formation.
✔️ **ANSWER** – B) Prevent blood clots
---
**2.** Which food should the client avoid?
,A) Apples
B) Spinach
C) Chicken
D) Rice
💡 **RATIONALE** – Spinach is high in vitamin K, which directly counteracts warfarin's mechanism of
action.
✔️ **ANSWER** – B) Spinach
---
**3.** Which sign of bleeding should be reported?
A) Headache
B) Dark stools
C) Nausea
D) Fatigue
💡 **RATIONALE** – Dark, tarry stools (melena) indicate upper gastrointestinal bleeding and require
immediate evaluation.
✔️ **ANSWER** – B) Dark stools
---
**4.** The client will require regular monitoring of:
A) Blood pressure
B) Blood glucose
C) INR
D) Temperature
,💡 **RATIONALE** – The International Normalized Ratio (INR) measures warfarin's anticoagulant
effect; target typically 2.0–3.0.
✔️ **ANSWER** – C) INR
---
**5.** The word "anticoagulant" means:
A) Promotes clotting
B) Prevents clotting
C) Destroys platelets
D) Increases blood viscosity
💡 **RATIONALE** – Anti- = against; coagulant = clotting. Anticoagulants prevent blood clot
formation.
✔️ **ANSWER** – B) Prevents clotting
---
**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 that acts on the thick ascending loop of
Henle to inhibit sodium, potassium, and chloride reabsorption.
✔️ **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 peripheral edema are classic signs of fluid
overload in heart failure due to decreased cardiac output.
✔️ **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 by decreasing osmotic pull for water
in the vascular space.
✔️ **ANSWER** – B) Limit sodium to 2 grams per day
