QUESTIONS AND CORRECT DETAILED ANSWERS WITH
RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A+
Q1. A client with heart failure is prescribed furosemide (Lasix). Which
finding is the priority to report to the provider?
A. Blood pressure 100/60 mmHg
B. Potassium 3.0 mEq/L
C. Weight loss of 1 kg in 24 hrs
D. Urine output 2000 mL in 24 hrs
Answer: B. Potassium 3.0 mEq/L
Rationale: Hypokalemia is a dangerous side effect of loop diuretics and
increases risk for dysrhythmias, especially in clients with heart disease. The
other findings are expected/less urgent.

Q2. A client with COPD is receiving oxygen therapy. Which order
requires the nurse to question?
A. Oxygen at 2 L/min via nasal cannula
B. Oxygen at 4 L/min via nasal cannula
C. Maintain O2 sat >90%
D. Titrate oxygen per protocol
Answer: B. Oxygen at 4 L/min via nasal cannula
Rationale: COPD patients rely on hypoxic drive; high-flow O2 can suppress
respirations. Typically kept ≤2 L/min unless otherwise ordered by
pulmonology.
Q3. A client with atrial fibrillation is prescribed warfarin (Coumadin).
Which lab value requires immediate intervention?
A. INR 2.4
B. INR 3.0
C. INR 6.0
D. INR 1.8
Answer: C. INR 6.0
Rationale: Therapeutic INR for AFib = 2–3. INR 6.0 indicates high risk for
bleeding → hold dose, notify provider.

Q4. The nurse is caring for a client after thoracentesis. Which
assessment finding requires immediate action?
A. Mild pain at puncture site
B. O2 sat drops from 96% to 88%
C. Respiratory rate 20
D. Client states feeling tired
Answer: B. O2 sat drops from 96% to 88%
Rationale: Sudden hypoxia may indicate pneumothorax, a complication of
thoracentesis. Requires rapid assessment and provider notification.
Q5. Which instruction should the nurse give a client taking
nitroglycerin for angina?

Q6. Which client is at highest risk for aspiration pneumonia?
A. Post-op hip replacement
B. Stroke patient with dysphagia
C. COPD patient on home O2
D. Client with DVT on anticoagulants
Answer: B. Stroke patient with dysphagia
Rationale: Impaired swallowing increases risk of food/liquid entering
airway.
Q7. A nurse notes ST elevation on a client’s ECG. What is the priority
intervention?
A. Start IV fluids
B. Administer oxygen
C. Notify provider
D. Give morphine IV
Answer: B. Administer oxygen
