Question 1
Clinical Scenario
A nurse is orienting a newly licensed graduate nurse to the
medication administration process on a medical-surgical unit. A
72-year-old client with hypertension, type 2 diabetes mellitus,
and chronic kidney disease is scheduled to receive several
morning medications. Before administering the medications,
the graduate nurse states, "The pharmacy already verified these
medications, so I don't need to compare them with the
medication administration record."
Question Stem
,Which response by the experienced nurse is most appropriate?
A. "You should always compare each medication with the
medication administration record before administration."
B. "It is acceptable to skip verification if the medications are in
unit-dose packaging."
C. "Only high-alert medications require comparison with the
medication administration record."
D. "Verification is only necessary when administering
medications intravenously."
Correct Answer
Correct Answer: A. You should always compare each
medication with the medication administration record before
administration.
Detailed Rationale
Medication safety begins with consistently following the rights
of medication administration and institutional verification
procedures. Even though the pharmacy reviews medication
orders, nurses remain responsible for independently verifying
the correct medication, dose, route, time, patient,
documentation, reason, response, education, and the patient's
right to refuse. Comparing the medication label with the
medication administration record (MAR) at recommended
checkpoints helps prevent administration errors involving look-
,alike/sound-alike drugs, incorrect dosages, or wrong-patient
errors.
Option B is incorrect because unit-dose packaging reduces—but
does not eliminate—the possibility of medication errors. The
nurse must still verify every medication.
Option C is incorrect because all medications, not only high-
alert medications, require verification. Although high-alert
medications demand additional safeguards, routine
medications can also cause significant harm if administered
incorrectly.
Option D is incorrect because verification is required regardless
of the route of administration. Oral, topical, subcutaneous,
intramuscular, and intravenous medications all require
appropriate safety checks.
Patient safety depends on systematic medication verification
rather than assumptions that previous healthcare professionals
have eliminated all potential errors.
Learning Objectives
After completing this question, the learner should be able to:
• Apply the medication verification process before
medication administration.
• Describe the nurse's responsibility for preventing
medication errors.
, • Identify the importance of the rights of medication
administration.
Medication Safety Focus
Medication administration
Question 2
Clinical Scenario
A nurse is caring for a 66-year-old client admitted with
community-acquired pneumonia. The provider prescribes an
oral antibiotic. Before administering the first dose, the nurse
reviews the client's history and notes a documented severe
anaphylactic reaction to penicillin. The prescribed antibiotic
belongs to the penicillin class.
Question Stem
Which nursing action is the priority?
A. Administer the medication while closely monitoring for a
reaction.
B. Contact the prescribing provider before administering the
medication.
C. Premedicate the client with diphenhydramine and administer
the antibiotic.
