Detailed Rationales |
Medication Safety, Clinical Judgment &
Nursing Exam Prep
Question 1
Clinical Scenario
A newly licensed nurse is preparing to administer medications
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 administration, the nurse compares the medication
administration record (MAR) with the provider's prescription,
reviews the client's allergies, verifies the client's identity using
two identifiers, and checks the client's latest laboratory results.
Question Stem
Which nursing action best demonstrates the application of the
principles of safe medication administration?
,A. Administer the medications as scheduled because they were
prepared by the previous nurse.
B. Verify the client's identity using two identifiers and compare
the medication with the MAR before administration.
C. Ask the client's spouse to confirm the medications being
administered.
D. Delay reviewing laboratory values until after the medications
have been administered.
Correct Answer
Correct Answer: B. Verify the client's identity using two
identifiers and compare the medication with the MAR before
administration.
Detailed Rationale
Safe medication administration begins with systematic
verification before a medication ever reaches the patient. Using
two approved patient identifiers and comparing the medication
with the MAR helps ensure the nurse is administering the
correct medication to the correct patient while supporting
several of the Rights of Medication Administration, including
the right patient, right medication, right dose, right route, right
time, and right documentation. Reviewing current laboratory
values before administering medications is equally important
because abnormal renal function, electrolyte disturbances, or
,coagulation results may require holding or modifying therapy.
This process reduces preventable medication errors and
promotes patient safety.
Option A is incorrect because medications should never be
administered solely because another nurse prepared them. The
administering nurse remains legally and professionally
responsible for verifying every medication before
administration.
Option C is incorrect because family members may provide
helpful history but cannot replace proper patient identification
procedures.
Option D is incorrect because laboratory review should occur
before administering medications that may be affected by renal
function, liver function, electrolyte balance, or other clinical
parameters.
Medication administration is a deliberate process requiring
assessment, verification, and clinical judgment before every
dose.
Learning Objectives
After completing this question, the learner should be able to:
• Apply essential medication safety principles before
administration.
• Identify appropriate patient identification procedures.
, • Recognize the importance of reviewing laboratory data
before medication administration.
• Describe the nurse's accountability during medication
administration.
Medication Safety Focus: Medication Administration
Question 2
Clinical Scenario
A 65-year-old client with heart failure is prescribed a medication
that is eliminated primarily through the kidneys. The client's
serum creatinine has increased from 0.9 mg/dL to 2.3 mg/dL
over the past three days. The nurse is preparing to administer
the next scheduled dose.
Question Stem
Which pharmacokinetic principle should guide the nurse's
clinical decision?
A. Reduced renal excretion may increase the risk of drug
accumulation and toxicity.
B. Renal impairment accelerates medication metabolism.
C. Kidney dysfunction has no effect on drug elimination.
