Medication Safety Review
Question 1
Clinical Scenario
A 72-year-old woman is admitted to a medical-surgical unit with
community-acquired pneumonia. Her history includes hypertension,
osteoarthritis, and stage 3 chronic kidney disease. During medication
reconciliation, the nurse discovers that the client takes prescription
medications from two specialists, several over-the-counter (OTC)
products, and an herbal supplement. The provider plans to prescribe
intravenous antibiotics.
Question Stem
Which nursing action is the highest priority before administering the
first dose of the prescribed medication?
,A. Review the complete medication list, including OTC medications and
herbal supplements, for potential interactions.
B. Administer the antibiotic immediately to prevent treatment delay.
C. Instruct the client to discontinue all OTC medications permanently.
D. Request that the pharmacy prepare medications in unit-dose
packaging.
Correct Answer
Correct Answer: A. Review the complete medication list, including OTC
medications and herbal supplements, for potential interactions.
Detailed Rationale
Medication reconciliation is a fundamental patient safety strategy
designed to identify discrepancies, prevent medication errors, and
reduce adverse drug events during transitions of care. Older adults
commonly receive medications from multiple providers and frequently
use OTC medications or herbal supplements that may alter drug
metabolism or increase bleeding, nephrotoxicity, or other adverse
effects. Before administering a newly prescribed antibiotic, the nurse
should ensure the complete medication history is accurate and evaluate
for potential interactions or duplications.
Option B is incorrect because timely treatment is important, but
administering medication before verifying safety violates safe
medication administration principles. Option C is incorrect because
many OTC medications may be appropriate, and discontinuation
requires provider guidance. Option D promotes medication safety but
,does not address the immediate risk of drug interactions before the first
dose.
The nurse should also verify allergies, previous adverse drug reactions,
renal and hepatic function when appropriate, and communicate any
concerns to the provider or pharmacist before medication
administration.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of medication reconciliation.
• Identify the importance of reviewing OTC and herbal medications.
• Prioritize actions that reduce medication errors.
• Apply medication safety principles during transitions of care.

Medication Reconciliation
Question 2
Clinical Scenario
A newly licensed nurse asks the charge nurse why two clients receiving
the same oral medication experience different therapeutic responses
despite receiving identical doses. Both clients have normal medication
administration records and no missed doses.
Question Stem
Which factor best explains the difference in medication response?
, A. Every medication produces identical effects regardless of patient
characteristics.
B. Individual differences in pharmacokinetics and pharmacodynamics
can alter medication response.
C. Oral medications always reach peak concentration at the same time
in every patient.
D. Therapeutic effects depend only on the prescribed dose.
Correct Answer
Correct Answer: B. Individual differences in pharmacokinetics and
pharmacodynamics can alter medication response.
Detailed Rationale
Pharmacokinetics describes how the body absorbs, distributes,
metabolizes, and excretes a medication, while pharmacodynamics
describes how the medication produces its therapeutic and adverse
effects. Age, genetics, organ function, body composition, concurrent
illnesses, and drug interactions all influence these processes. As a
result, two patients receiving the same dose may experience different
therapeutic outcomes or adverse effects.
Option A is incorrect because medication response varies widely among
individuals. Option C is incorrect because absorption rates differ
depending on gastrointestinal function, food intake, blood flow, and
formulation. Option D is incorrect because dose alone does not
determine therapeutic response; patient-specific factors are equally
important.
