LPN/LVN Week 6 Comprehensive Review Quiz 2026 UPDATE |SBON
1. A nurse is caring for a client with heart failure who is prescribed furosemide.
Which laboratory value should the nurse monitor most closely?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum phosphorus
Answer: B
Rationale: Furosemide is a loop diuretic that causes the excretion of potassium, potentially
leading to hypokalemia.
2. A client is in the first stage of labor. The nurse notes that the fetal heart rate
(FHR) shows early decelerations. What is the appropriate nursing action?
A. Administer oxygen at 10L via non-rebreather mask
B. Document the finding and continue to monitor
C. Place the client in a Trendelenburg position
D. Prepare for an emergency Cesarean section
Answer: B
Rationale: Early decelerations are caused by fetal head compression and are considered a
normal, reassuring finding during labor.
,3. Which of the following tasks is appropriate for an LPN/LVN to delegate to an
Unlicensed Assistive Personnel (UAP)?
A. Assisting a stable client with ambulation
B. Performing an initial skin assessment on a new admission
C. Teaching a client how to use a glucose monitor
D. Administering a nebulizer treatment
Answer: A
Rationale: UAPs can perform routine tasks like ambulating stable clients. Assessment,
teaching, and medication administration require licensed nursing judgment.
4. A client with type 1 diabetes mellitus is found unconscious and clammy. What
should be the nurse’s first action?
A. Administer 15g of simple carbohydrates orally
B. Administer glucagon IM or SC per protocol
C. Check the client’s blood glucose level
D. Call the primary healthcare provider
Answer: B
Rationale: If a client is unconscious and hypoglycemia is suspected, glucagon is
administered because the client cannot safely swallow oral carbohydrates.
5. Which physical assessment finding is most characteristic of a child with
Tetralogy of Fallot?
A. Bounding peripheral pulses
B. Machine-like murmur
C. Clubbing of the fingers
D. High blood pressure in the arms
Answer: C
Rationale: Clubbing of the fingers is a sign of chronic hypoxia, which is common in
cyanotic heart defects like Tetralogy of Fallot.
, 6. A nurse is reinforcing teaching for a client taking lithium carbonate. Which
dietary instruction is essential?
A. Restrict sodium intake to less than 2g per day
B. Increase intake of green leafy vegetables
C. Avoid foods high in tyramine
D. Maintain a consistent intake of salt and fluids
Answer: D
Rationale: Lithium is a salt; a decrease in sodium intake can cause lithium retention and
toxicity, while an increase can lower lithium levels.
7. What is the priority assessment for a client who just returned from a cardiac
catheterization via the femoral artery?
A. Range of motion in the affected leg
B. Pedal pulses and insertion site for bleeding
C. Client’s ability to void
D. Oral temperature every 4 hours
Answer: B
Rationale: Post-cardiac catheterization, the nurse must monitor for hemorrhage and
peripheral ischemia in the affected extremity.
8. A client is diagnosed with bacterial meningitis. Which type of precautions
should the nurse implement?
A. Droplet precautions
B. Airborne precautions
C. Contact precautions
D. Standard precautions only
Answer: A
Rationale: Bacterial meningitis is transmitted through respiratory droplets; therefore,
droplet precautions are required for the first 24 hours of antibiotic therapy.
