Questions with Detailed Rationales
Question 1
Clinical Scenario
A newly licensed nurse is preparing morning medications for
four clients on a medical-surgical unit. Before administering
medications, the nurse verifies the provider's prescription,
reviews the medication administration record (MAR), confirms
the client's allergies, and uses two patient identifiers. One client
asks why the nurse continues checking the medication label
multiple times.
Question Stem
Which response by the nurse best explains the purpose of
repeated medication verification?
,A. "Checking the medication label multiple times helps prevent
medication administration errors by ensuring the correct
medication is given to the correct patient."
B. "It is primarily done to satisfy documentation requirements
before medication administration."
C. "It allows me to determine whether the medication should
be administered with food."
D. "It confirms that the medication is covered by your
insurance."
Correct Answer
Correct Answer: A. Checking the medication label multiple
times helps prevent medication administration errors by
ensuring the correct medication is given to the correct patient.
Detailed Rationale
Medication safety begins before a medication ever reaches the
patient. Nurses are expected to compare the medication label
with the MAR at least three times: when obtaining the
medication, during preparation, and immediately before
administration. These repeated checks reduce the risk of
administering the wrong medication, incorrect dose, or wrong
formulation. In addition, nurses should verify the rights of
medication administration—including the right patient,
medication, dose, route, time, documentation, reason,
,response, and the patient's right to refuse. Using two approved
patient identifiers further decreases the likelihood of patient
identification errors. Explaining this process to patients
promotes transparency and reinforces a culture of safety.
Option B is incorrect because documentation is important but is
not the primary purpose of repeated label verification.
Option C is incorrect because administration instructions should
already be reviewed before preparation and are not the main
reason for repeated checks.
Option D is incorrect because insurance verification is not part
of bedside medication administration.
Medication errors remain one of the most preventable causes
of patient harm. Consistent adherence to standardized
medication safety practices is a fundamental nursing
responsibility.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of repeated medication verification.
• Apply the rights of medication administration.
• Describe nursing strategies that reduce medication errors.

, Question 2
Clinical Scenario
A 78-year-old client with chronic kidney disease is admitted for
pneumonia. The provider prescribes gentamicin IV. Before
administering the first dose, the nurse reviews the client's
laboratory results:
• Serum creatinine: 2.4 mg/dL
• BUN: 38 mg/dL
• Estimated GFR: 28 mL/min/1.73 m²
The client reports normal hearing and denies medication
allergies.
Question Stem
Which nursing action is the priority before administering the
medication?
A. Administer the medication immediately because delaying
antibiotics increases infection risk.
B. Contact the provider to discuss the client's renal function
before administering gentamicin.
C. Encourage the client to increase oral fluid intake.
D. Administer an antiemetic before the infusion.
