1. A nurse is preparing to administer digoxin to a client with heart failure. Which
assessment finding requires withholding the medication and notifying the provider?
A. Blood pressure 138/80 mm Hg
B. Apical pulse 54 beats/min
C. Respiratory rate 18 breaths/min
D. Oxygen saturation 96%
Answer: B. Apical pulse 54 beats/min
Rationale: Digoxin slows heart rate. The medication should generally be withheld if the
adult apical pulse is below 60 beats/min because of the increased risk of severe
bradycardia and heart block. The provider should be notified before administration.
2. A client receiving intravenous vancomycin suddenly develops flushing, itching, and
hypotension. What is the nurse's priority action?
A. Increase the infusion rate
B. Stop the infusion immediately
C. Administer the next dose early
D. Encourage oral fluids
Answer: B. Stop the infusion immediately
Rationale: These findings are consistent with infusion-related "Red Man Syndrome." The
nurse should stop the infusion, assess the client, notify the provider, and anticipate
restarting the medication more slowly if appropriate.
, 3. A client is prescribed warfarin therapy. Which laboratory value is most important for
evaluating therapeutic effectiveness?
A. Hemoglobin
B. INR
C. Platelet count
D. White blood cell count
Answer: B. INR
Rationale: The International Normalized Ratio (INR) is used to monitor warfarin therapy.
Most therapeutic ranges are between 2.0 and 3.0 for many indications, although the goal
varies based on the client's condition.
4. Which medication should the nurse question before administering to a client with a
documented allergy to penicillin?
A. Azithromycin
B. Cephalexin
C. Doxycycline
D. Ciprofloxacin
Answer: B. Cephalexin
Rationale: Cephalexin is a first-generation cephalosporin. Although cross-reactivity is
uncommon, caution is warranted, particularly if the client has had a severe or immediate
hypersensitivity reaction to penicillin.
5. Which instruction is most appropriate for a client taking tetracycline?
A. Take with milk.
B. Avoid sun exposure.
C. Take immediately before bedtime.
D. Increase grapefruit juice intake.
Answer: B. Avoid sun exposure.
Rationale: Tetracyclines commonly cause photosensitivity. Clients should use sunscreen,
wear protective clothing, and avoid prolonged sun exposure. Dairy products reduce drug
absorption.
, 6. A nurse administers regular insulin at 7:30 AM. When should the nurse expect the
medication to reach its peak action?
A. 8:00 AM
B. 10:00 AM
C. 1:30 PM
D. 8:00 PM
Answer: B. 10:00 AM
Rationale: Regular insulin generally peaks 2 to 4 hours after administration. During the peak
period, clients are at greatest risk for hypoglycemia.
7. Which electrolyte imbalance is most likely in a client taking furosemide?
A. Hyperkalemia
B. Hypokalemia
C. Hypermagnesemia
D. Hypercalcemia
Answer: B. Hypokalemia
Rationale: Loop diuretics increase potassium excretion, placing clients at risk for
hypokalemia, muscle weakness, dysrhythmias, and digitalis toxicity.
8. Which assessment finding indicates therapeutic effectiveness of morphine?
A. Respiratory rate 8 breaths/min
B. Pain rating decreased from 9 to 3
C. Blood pressure 80/50 mm Hg
D. Pinpoint pupils
Answer: B. Pain rating decreased from 9 to 3
Rationale: The primary therapeutic goal of morphine is pain relief. Respiratory depression
and hypotension are adverse effects rather than desired outcomes.
9. Which medication requires the nurse to monitor serum lithium levels regularly?
