LPN/LVN Comprehensive Practice Exam (NCLEX-PN Format) 2026
UPDATE |SBON
1. Which laboratory value should the LPN monitor for a patient receiving
Warfarin (Coumadin)?
A. Partial Thromboplastin Time (PTT)
B. Serum Potassium
C. Blood Urea Nitrogen (BUN)
D. International Normalized Ratio (INR)
Answer: D
Rationale: Warfarin therapy is monitored using the PT and INR values to ensure the
patient stays within the therapeutic range.
2. A patient with heart failure is prescribed Furosemide. Which electrolyte
imbalance is most likely to occur?
A. Hyperkalemia
B. Hypercalcemia
C. Hypokalemia
D. Hyponatremia
Answer: C
Rationale: Furosemide is a loop diuretic that causes the excretion of potassium, often
leading to hypokalemia.
,3. What is the priority nursing action when a patient reports sudden chest pain
and shortness of breath?
A. Administer an oral analgesic
B. Encourage the patient to walk around
C. Call the patient’s family
D. Obtain an EKG and assess vital signs
Answer: D
Rationale: Chest pain and dyspnea indicate a potential cardiac or respiratory emergency
requiring immediate assessment and diagnostic data.
4. A nurse is preparing to administer Digoxin. At what heart rate should the
dose be withheld for an adult?
A. Less than 100 bpm
B. Less than 80 bpm
C. Greater than 110 bpm
D. Less than 60 bpm
Answer: D
Rationale: Digoxin should be withheld if the apical pulse is less than 60 bpm in an adult to
prevent bradycardia and toxicity.
5. Which type of insulin has the fastest onset of action?
A. NPH
B. Glargine
C. Lispro
D. Regular
Answer: C
Rationale: Lispro is a rapid-acting insulin with an onset of approximately 15 minutes.
, 6. A patient is suspected of having tuberculosis. Which type of precautions
should be implemented?
A. Airborne precautions
B. Droplet precautions
C. Standard precautions only
D. Contact precautions
Answer: A
Rationale: Tuberculosis is transmitted via small droplets that remain suspended in the air,
requiring airborne precautions (N95 mask and negative pressure room).
7. Which of the following is a symptom of hypoglycemia?
A. Extreme thirst
B. Diaphoresis and shakiness
C. Fruit-scented breath
D. Increased urination
Answer: B
Rationale: Hypoglycemia (low blood sugar) typically causes sweating, tremors, and
tachycardia.
8. What is the correct position for a patient after a liver biopsy to prevent
hemorrhage?
A. Right side-lying
B. Supine with legs elevated
C. Left side-lying
D. High Fowler’s
Answer: A
Rationale: Placing the patient on the right side applies pressure to the liver site to prevent
bleeding.
