Question 1
A nurse is preparing to administer a medication that is known to have a narrow therapeutic index. Which action
is most important for the nurse to take?
A. Administer the medication with food to enhance absorption
B. Monitor the client's serum drug levels regularly
C. Administer the medication at the same time each day
D. Assess the client for allergic reactions before administration
🟢 Correct Answer:
B. Monitor the client's serum drug levels regularly
🔴 RATIONALE:
A narrow therapeutic index means the difference between therapeutic and toxic doses is small. Close
monitoring of serum drug levels is essential to prevent toxicity while ensuring therapeutic effectiveness. While
administering with food, consistent timing, and assessing for allergies are important, they do not address the
specific risk associated with a narrow therapeutic index.
,Question 2
A client prescribed digoxin (Lanoxin) reports nausea, vomiting, and seeing yellow halos around lights. Which
action should the nurse take first?
A. Administer an antiemetic
B. Hold the next dose of digoxin and notify the healthcare provider
C. Encourage the client to eat small, frequent meals
D. Obtain a serum digoxin level
🟢 Correct Answer:
B. Hold the next dose of digoxin and notify the healthcare provider
🔴 RATIONALE:
Nausea, vomiting, and visual disturbances (yellow or green halos) are classic signs of digoxin toxicity. The nurse
should hold the next dose and notify the healthcare provider immediately. While obtaining a serum digoxin
level is important, it is not the first action; holding the medication prevents further toxicity.
Question 3
A nurse is reinforcing teaching for a client prescribed an ACE inhibitor for hypertension. Which side effect
should the client be instructed to report?
A. Dry cough
B. Weight gain
,C. Bradycardia
D. Hyperglycemia
🟢 Correct Answer:
A. Dry cough
🔴 RATIONALE:
A persistent dry cough is a common side effect of ACE inhibitors due to the accumulation of bradykinin. Clients
should report this side effect as it may require a change in medication. Weight gain, bradycardia, and
hyperglycemia are not typically associated with ACE inhibitors.
Question 4
A client is prescribed warfarin (Coumadin) and asks the nurse about dietary restrictions. Which food should the
nurse instruct the client to maintain a consistent intake of?
A. Apples
B. Green leafy vegetables
C. Whole grains
D. Dairy products
🟢 Correct Answer:
B. Green leafy vegetables
, 🔴 RATIONALE:
Green leafy vegetables are high in vitamin K, which can interfere with warfarin's anticoagulant effect. The client
should maintain a consistent intake of vitamin K-rich foods to avoid fluctuations in INR. Apples, whole grains,
and dairy products do not significantly affect warfarin metabolism.
Question 5
A nurse is preparing to administer an intramuscular injection of a viscous medication. Which needle gauge is
most appropriate?
A. 18-gauge
B. 21-gauge
C. 25-gauge
D. 27-gauge
🟢 Correct Answer:
B. 21-gauge
🔴 RATIONALE:
A 21-gauge needle is appropriate for viscous intramuscular medications as it allows the medication to flow
easily while being large enough for proper delivery. An 18-gauge needle is too large and may cause tissue
trauma; 25-gauge and 27-gauge needles are too small for viscous medications.
