Rationales
Question 1
Clinical Scenario
A 72-year-old woman is admitted with community-acquired
pneumonia. She has a history of hypertension, type 2 diabetes
mellitus, and osteoarthritis. During medication reconciliation,
the nurse discovers the client takes prescription medications
from two providers, several over-the-counter (OTC) products,
and an herbal supplement. The client states, "I didn't mention
the vitamins because they're natural, so they don't count as
medications."
Question Stem
,Which nursing response is most appropriate?
A. "Natural products are generally safe and do not need to be
reported."
B. "Only prescription medications should be included during
medication reconciliation."
C. "Please include all prescription medications, OTC products,
vitamins, and herbal supplements because they can affect your
treatment."
D. "We only document medications that were prescribed within
the last month."
Correct Answer
Correct Answer: C. "Please include all prescription
medications, OTC products, vitamins, and herbal supplements
because they can affect your treatment."
Detailed Rationale
Medication reconciliation is a critical patient safety process that
involves creating the most accurate list possible of every
medication a patient is taking, including prescription drugs, OTC
medications, vitamins, minerals, herbal supplements, and
dietary products. Many "natural" products can significantly
interact with prescribed medications. For example, St. John's
wort can reduce the effectiveness of numerous medications by
inducing hepatic enzymes, while ginkgo biloba and garlic
,supplements may increase bleeding risk when combined with
anticoagulants. Failure to obtain a complete medication history
increases the risk of adverse drug events, duplicate therapy,
medication omissions, and harmful interactions.
Option A is incorrect because natural products are not
inherently safe and may produce serious adverse effects or drug
interactions. Option B is incorrect because OTC products and
supplements are essential components of medication
reconciliation. Option D is incorrect because all current
medications should be documented regardless of when they
were prescribed. Nurses play a vital role in obtaining a
comprehensive medication history, encouraging patients to
bring medication lists or bottles to healthcare visits, and
communicating discrepancies to the healthcare team to reduce
medication errors and improve patient outcomes.
Learning Objectives
After completing this question, the learner should be able to:
• Describe the purpose of medication reconciliation.
• Recognize the importance of documenting OTC and herbal
products.
• Identify potential safety risks associated with incomplete
medication histories.

Question 2
Clinical Scenario
A nurse is preparing to administer a newly prescribed oral
antihypertensive medication to a hospitalized client. Before
administering the medication, the nurse confirms the client's
identity using two approved identifiers, reviews allergies,
compares the medication label with the medication
administration record (MAR), and verifies the prescribed dose.
Question Stem
Which medication administration principle is the nurse
demonstrating by verifying the medication label against the
MAR before administration?
A. Prevention of medication administration errors through
adherence to the rights of medication administration
B. Assessment of the medication's therapeutic effectiveness
C. Evaluation of the client's response to treatment
D. Documentation of medication side effects
