LPN Semester 3 Comprehensive Review 2026/2027 UPDATE
1. A nurse is caring for a client with Congestive Heart Failure (CHF) who is
receiving Furosemide. Which laboratory value is the priority for the nurse to
monitor?
A. Serum Sodium
B. Serum Glucose
C. Serum Calcium
D. Serum Potassium
Answer: D
Rationale: Furosemide is a loop diuretic that causes the excretion of potassium.
Hypokalemia can lead to dangerous cardiac arrhythmias.
2. Which clinical manifestation should the nurse expect to see in a client
diagnosed with Grave’s Disease?
A. Bradycardia
B. Exophthalmos
C. Weight gain
D. Cold intolerance
Answer: B
Rationale: Exophthalmos (bulging eyes) is a classic sign of hyperthyroidism/Grave’s
Disease. Other options describe hypothyroidism.
,3. An LPN is preparing to administer Digoxin to a client. Which action must the
nurse take first?
A. Check the client’s blood pressure
B. Auscultate the apical pulse for 1 full minute
C. Measure the client’s intake and output
D. Review the client’s most recent PT/INR
Answer: B
Rationale: Digoxin should be held if the apical pulse is less than 60 bpm in adults to
prevent bradycardia.
4. A client is 2 hours post-operative following a thyroidectomy. Which
equipment is most important to have at the bedside?
A. Incentive spirometer
B. Sequential compression devices
C. Nasoenteric tube
D. Tracheostomy tray
Answer: D
Rationale: Post-thyroidectomy, laryngeal edema or hemorrhage can cause airway
obstruction; a tracheostomy tray is a priority for emergency airway management.
5. A client with Type 1 Diabetes Mellitus is found unconscious and clammy.
What is the nurse’s priority action?
A. Administer 10 units of regular insulin
B. Check the blood glucose level
C. Administer Glucagon IM
D. Provide a complex carbohydrate snack
Answer: C
Rationale: In an unconscious client with suspected hypoglycemia, Glucagon IM or IV
Dextrose is indicated when the client cannot swallow.
, 6. Which of the following tasks is most appropriate for the LPN to delegate to an
Unlicensed Assistive Personnel (UAP)?
A. Performing a sterile dressing change
B. Teaching a client how to use a walker
C. Evaluating the effectiveness of pain medication
D. Assisting a stable client with a bed bath
Answer: D
Rationale: UAPs can perform ADLs like bathing for stable clients. Teaching, evaluating, and
sterile procedures are the nurse’s responsibility.
7. A nurse is assessing a client with a Chest Tube. What should the nurse do if
the tube becomes disconnected from the drainage system?
A. Clamp the tube immediately with two clamps
B. Cover the site with an occlusive dressing
C. Instruct the client to inhale and hold their breath
D. Place the end of the tube in a bottle of sterile water
Answer: D
Rationale: Placing the end of the tube in sterile water creates a temporary water seal and
prevents air from entering the pleural space.
8. A client is prescribed Lithium Carbonate for Bipolar Disorder. The nurse
should instruct the client to maintain an adequate intake of which substance?
A. Vitamin K
B. Calcium
C. Potassium
D. Sodium
Answer: D
Rationale: Low sodium levels can lead to lithium toxicity because the kidneys reabsorb
lithium when sodium is low.
