Nursing Exam Study Guide
Question 1
Clinical Scenario
A 68-year-old man is admitted to the medical unit with
community-acquired pneumonia. His medical history includes
hypertension, type 2 diabetes mellitus, and chronic kidney
disease. During medication reconciliation, the nurse notices
that the patient takes several prescription medications, an over-
the-counter pain reliever, and an herbal supplement daily. The
patient states, "I usually don't tell my healthcare providers
about the vitamins and herbal products because they aren't
real medicines."
Question Stem
Which response by the nurse is the most appropriate?
,A. "Herbal supplements and over-the-counter medications can
interact with prescription medications and should always be
reported."
B. "Only prescription medications are documented because
they have the greatest effect on treatment."
C. "You should stop taking all herbal supplements while you are
hospitalized."
D. "Herbal products are regulated the same way as prescription
medications, so interactions are uncommon."
Correct Answer
Correct Answer: A. Herbal supplements and over-the-counter
medications can interact with prescription medications and
should always be reported.
Detailed Rationale
Medication reconciliation is a critical safety process that
involves obtaining a complete and accurate list of all substances
a patient takes, including prescription medications, over-the-
counter (OTC) products, vitamins, herbal supplements, and
dietary supplements. Many herbal products can significantly
alter the effects of prescribed medications. For example, St.
John's wort may reduce the effectiveness of numerous drugs by
inducing hepatic enzymes, while ginkgo biloba may increase
bleeding risk when combined with anticoagulants. Accurate
,medication histories help prevent adverse drug events,
duplicate therapy, contraindications, and potentially life-
threatening interactions.
Option B is incorrect because OTC medications and
supplements can produce clinically significant effects and must
be documented. Option C is inappropriate because patients
should not discontinue supplements without provider
evaluation, as some require gradual discontinuation or
individualized assessment. Option D is incorrect because herbal
supplements are not regulated to the same standards as
prescription medications, and their potency and interactions
may vary considerably. Nurses play a vital role in educating
patients about the importance of reporting every substance
they take to promote safe medication administration and
continuity of care.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of medication reconciliation.
• Identify the importance of documenting OTC and herbal
medications.
• Recognize potential interactions between supplements and
prescription medications.
• Promote patient education regarding medication safety.
, Medication Safety Focus: Medication Reconciliation
Question 2
Clinical Scenario
A nurse is preparing to administer the first dose of an
intravenous antibiotic to a 42-year-old woman admitted with
pyelonephritis. Before administering the medication, the nurse
reviews the electronic health record and notes that the patient
has a documented allergy to penicillin that previously caused
facial swelling and difficulty breathing.
Question Stem
Which nursing action should the nurse take first?
A. Administer the medication slowly while closely monitoring
the patient.
B. Clarify the medication order with the prescribing provider
before administration.
C. Premedicate the patient with diphenhydramine.
D. Ask the patient whether she still believes she is allergic to
penicillin.
