Question 1
Clinical Scenario
A nurse is caring for a 68-year-old client newly admitted with
community-acquired pneumonia. During medication reconciliation, the
client reports taking several prescription medications, an over-the-
counter sleep aid, and two herbal supplements daily. The provider plans
to prescribe an antibiotic. Before administering the first dose, the nurse
reviews the client's complete medication list.
Question Stem
Which nursing action best demonstrates the purpose of medication
reconciliation?
A. Comparing the client's current medications with newly prescribed
medications to identify potential discrepancies and interactions
,B. Administering all home medications immediately after hospital
admission
C. Asking the client to discontinue all over-the-counter medications
during hospitalization
D. Waiting until discharge to review medications with the client
Correct Answer
Correct Answer: A. Comparing the client's current medications with
newly prescribed medications to identify potential discrepancies and
interactions
Detailed Rationale
Medication reconciliation is a structured process designed to improve
medication safety by ensuring an accurate and complete medication list
is maintained whenever a patient transitions between healthcare
settings. This includes prescription medications, over-the-counter
products, vitamins, and herbal supplements. Comparing the client's
home medications with new prescriptions helps identify omissions,
duplications, dosing errors, contraindications, and clinically significant
drug interactions before harm occurs. This process reduces preventable
adverse drug events and promotes continuity of care.
Option B is incorrect because home medications should never be
automatically continued. Each medication requires evaluation for
appropriateness during the current illness, renal and hepatic function,
allergies, and potential interactions with newly prescribed therapies.
,Option C is incorrect because some over-the-counter medications may
be appropriate to continue, while others require discontinuation.
Decisions should be individualized rather than automatic.
Option D is incorrect because reconciliation should occur at every
transition of care—including admission, transfers, and discharge—not
solely at discharge.
Nurses play a vital role by verifying medication histories, clarifying
discrepancies with providers and pharmacists, educating patients about
medication changes, and documenting the final reconciled medication
list accurately.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of medication reconciliation.
• Identify nursing responsibilities during transitions of care.
• Recognize how medication reconciliation reduces medication
errors.
• Apply medication safety principles during hospital admission.
Medication Safety Focus: Medication reconciliation
Question 2
Clinical Scenario
A nurse prepares to administer an oral antihypertensive medication to a
hospitalized client. Before giving the medication, the nurse confirms the
client's identity using two approved identifiers, compares the
, medication administration record with the medication label, checks the
expiration date, and asks the client about allergies.
Question Stem
Which medication administration principle is primarily demonstrated by
these nursing actions?
A. Reducing medication costs
B. Following the rights of medication administration to prevent
medication errors
C. Encouraging medication adherence after discharge
D. Evaluating therapeutic drug concentrations
Correct Answer
Correct Answer: B. Following the rights of medication administration
to prevent medication errors
Detailed Rationale
The nurse's actions reflect adherence to the established rights of
medication administration, which form the foundation of safe
medication practice. Verifying patient identity, confirming allergies,
comparing medication labels with the medication administration
record, and checking expiration dates all reduce the likelihood of
preventable medication errors. Modern nursing practice extends
beyond the traditional "five rights" to include additional safety
principles such as documentation, assessment, patient education,
evaluation, and the patient's right to refuse medication.
