Question 1
Clinical Scenario
A 68-year-old man is admitted with community-acquired pneumonia.
His medical history includes hypertension, type 2 diabetes mellitus, and
chronic kidney disease stage 3. During medication reconciliation, the
nurse discovers that the patient takes several prescription medications,
an over-the-counter ibuprofen product daily for knee pain, and an
herbal supplement. The provider is preparing to prescribe additional
medications for the hospitalization.
Question Stem
Which nursing action is the highest priority before administering newly
prescribed medications?
,A. Ask the patient to discontinue all herbal supplements immediately.
B. Complete a thorough medication reconciliation, including
prescription, over-the-counter, and herbal products.
C. Administer the prescribed antibiotics before obtaining a complete
medication history.
D. Encourage the patient to bring all medication bottles from home
after discharge.
Correct Answer
Correct Answer: B. Complete a thorough medication reconciliation,
including prescription, over-the-counter, and herbal products.
Detailed Rationale
Medication reconciliation is a critical safety process performed
whenever a patient transitions between healthcare settings. It involves
obtaining a complete and accurate list of all medications—including
prescription drugs, over-the-counter products, vitamins, herbal
supplements, and dietary supplements—to identify omissions,
duplications, interactions, contraindications, and potential adverse
effects before new medications are prescribed or administered. In this
scenario, the patient's chronic kidney disease and daily NSAID use
increase the risk of nephrotoxicity and drug interactions, making
reconciliation essential before initiating additional therapy.
Option A is incorrect because herbal supplements should not
automatically be discontinued without provider evaluation. Some
supplements interact significantly with prescribed medications, but
individualized assessment is required.
,Option C is incorrect because although timely antibiotic administration
is important, medication safety begins with verifying the complete
medication history to prevent serious interactions or contraindications.
Option D is helpful for future care but does not address the immediate
safety concern before medication administration.
Medication reconciliation reduces medication errors, adverse drug
events, and duplicate therapy. Nurses play a central role by verifying
medication histories, documenting allergies, clarifying discrepancies
with providers, and educating patients about maintaining updated
medication lists.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of medication reconciliation.
• Identify all medication sources that should be included in a
medication history.
• Prioritize medication safety before administering new
prescriptions.
• Recognize the nurse's role in preventing medication errors.
Medication Safety Focus: Medication Reconciliation
Question 2
Clinical Scenario
A nurse prepares to administer an oral antihypertensive medication to a
74-year-old woman. Before administration, the nurse verifies the
, patient's identity using two identifiers, compares the medication
administration record with the medication label three times, confirms
the dose, and assesses the patient's blood pressure.
Question Stem
Which pharmacology principle is the nurse primarily applying to reduce
medication errors?
A. The Rights of Medication Administration
B. First-pass metabolism
C. Therapeutic drug monitoring
D. Drug half-life determination
Correct Answer
Correct Answer: A. The Rights of Medication Administration
Detailed Rationale
The Rights of Medication Administration provide the foundation for safe
medication practice and significantly reduce preventable medication
errors. Although healthcare organizations may expand the list, core
principles include the right patient, medication, dose, route, time,
documentation, reason, response, and the patient's right to refuse.
Verifying patient identity with two identifiers, checking medication
labels against the medication administration record multiple times,
assessing relevant clinical data (such as blood pressure before an
antihypertensive), and documenting appropriately all demonstrate
adherence to these safety principles.
