300 REAL EXAM QUESTIONS AND CORRECT VERIFIED
ANSWERS/ ALREADY GRADED A+ (MOST RECENT!!)
1. A client with heart failure has a prescription for furosemide
40 mg IV. Which laboratory value requires the nurse to notify
the provider before administering?
A. Sodium 135 mEq/L
B. Potassium 2.8 mEq/L
C. Creatinine 0.9 mg/dL
D. Glucose 110 mg/dL
Correct Answer: B
Rationale: Furosemide is a loop diuretic that can worsen
hypokalemia (K <3.5). Severe hypokalemia (2.8) increases risk
of arrhythmias and digoxin toxicity.
2. A client with chronic obstructive pulmonary disease (COPD)
has an oxygen saturation of 86% on room air. The nurse
initiates oxygen at 2 L/min via nasal cannula. Which finding
1
,2
indicates a complication of oxygen therapy?
A. Respiratory rate of 22 breaths/min
B. Client reports headache
C. Oxygen saturation increases to 92%
D. Respiratory rate decreases to 10 breaths/min
Correct Answer: D
Rationale: COPD clients with chronic hypercapnia rely on hypoxic
drive. Oxygen can reduce respiratory drive, causing
hypoventilation and CO2 narcosis. A decrease in respiratory
rate is an early warning.
3. A client is admitted with acute pancreatitis. Which
laboratory finding is most consistent with this diagnosis?
A. Serum amylase 60 U/L
B. Serum lipase 450 U/L
C. Serum calcium 10.5 mg/dL
D. Blood glucose 85 mg/dL
Correct Answer: B
Rationale: Lipase is more specific than amylase for acute
pancreatitis. Normal lipase is 10–140 U/L; 450 U/L indicates
pancreatic inflammation.

4. A nurse is caring for a client with a nasogastric (NG) tube
set to low intermittent suction. The nurse notes that the pH of
aspirated fluid is 6.0. Which action should the nurse take?
A. Document the finding as normal
B. Irrigate the tube with 30 mL of water
C. Confirm tube placement with x-ray
D. Administer an antacid
Correct Answer: C
Rationale: Gastric pH should be ≤4.0. pH 6.0 suggests possible
placement in the small intestine or lungs. X-ray is the gold
standard for confirmation.
5. A client with atrial fibrillation is prescribed warfarin. Which
INR value indicates a therapeutic level for this client?
A. 1.0
B. 1.5
C. 2.5
D. 4.0
3
, 4
Correct Answer: C
Rationale: For atrial fibrillation, therapeutic INR is 2.0–3.0. 2.5 is
within range. INR 4.0 increases bleeding risk.
6. A client with end-stage renal disease (ESRD) is receiving
hemodialysis. Which finding would indicate the need to notify
the provider immediately?
A. Blood pressure 110/70 mm Hg
B. Potassium 5.0 mEq/L
C. Temperature 101.5°F
D. Weight gain of 1 kg between dialyses
Correct Answer: C
Rationale: Fever may indicate bacteremia or access infection;
dialysis should be withheld until blood cultures are obtained and
antibiotics initiated.
7. A client with type 1 diabetes mellitus is found
unresponsive. The blood glucose is 35 mg/dL. After
administering 1 mg of glucagon IM, the client regains
consciousness. Which action should the nurse take next?
A. Provide a complex carbohydrate snack
