1. A nurse is caring for a client with a history of congestive heart failure. Which
clinical finding is the most reliable indicator of fluid volume increase?
A. Pitting edema in the lower extremities
B. Increased blood pressure
C. Daily weight gain
D. Adventitious breath sounds
Answer: C
Rationale: Daily weight is the most reliable and objective indicator of fluid status changes
in a client with heart failure.
2. A client is prescribed Digoxin. Which laboratory result should the nurse
monitor most closely to prevent toxicity?
A. Sodium level
B. Chloride level
C. Calcium level
D. Potassium level
Answer: D
Rationale: Hypokalemia (low potassium) increases the risk of Digoxin toxicity, so
monitoring potassium is vital.
,3. The nurse is reinforcing teaching for a client with Type 1 Diabetes about site
rotation for insulin. Why is this practice necessary?
A. To reduce the risk of infection
B. To increase the speed of absorption
C. To prevent lipodystrophy
D. To decrease the pain of injection
Answer: C
Rationale: Rotating injection sites prevents lipodystrophy, which is the loss or abnormal
distribution of subcutaneous fat that can affect insulin absorption.
4. Which assessment finding should the nurse report immediately for a client
who just returned from a thyroidectomy?
A. Tingling in the fingers and toes
B. Hoarseness of the voice
C. Sore throat when swallowing
D. Pain at the incision site
Answer: A
Rationale: Tingling in the extremities (paresthesia) can indicate hypocalcemia due to
accidental parathyroid damage, which is a medical emergency.

type of isolation precautions should be implemented?
A. Contact precautions
B. Airborne precautions
C. Droplet precautions

A. Massaging the affected leg to relieve pain
B. Elevating the affected extremity
C. Ambulating the client three times a day
D. Applying cold compresses to the calf

7. What is the first action a nurse should take when a client’s pulse oximetry
reading drops from 95% to 88%?
A. Notify the healthcare provider
B. Administer supplemental oxygen
C. Check the probe placement

should the nurse advise the client to avoid?
A. Ibuprofen
