Nursing Pharmacology Study Guide
Question 1
Clinical Scenario
A 72-year-old woman is admitted with community-acquired
pneumonia. Her medical history includes hypertension, chronic
kidney disease (stage 3), and osteoarthritis. She reports taking
several prescription medications, over-the-counter ibuprofen
for knee pain, and an herbal supplement recommended by a
friend. During admission, the nurse begins collecting her
medication history before the provider writes new medication
orders.
Question Stem
Which nursing action is the highest priority to promote safe
pharmacologic care?
,A. Obtain a complete list of all prescription, over-the-counter,
herbal, and dietary supplements the client uses.
B. Ask the client to stop taking all over-the-counter medications
immediately.
C. Delay medication administration until the client's family
provides medication bottles.
D. Focus only on medications prescribed within the past month.
Correct Answer
Correct Answer: A. Obtain a complete list of all prescription,
over-the-counter, herbal, and dietary supplements the client
uses.
Detailed Rationale
Medication reconciliation begins with obtaining the most
complete and accurate medication history possible. This
includes prescription medications, over-the-counter (OTC)
drugs, vitamins, herbal products, and dietary supplements
because each may interact with newly prescribed medications
or affect existing disease processes. Older adults commonly
take multiple medications, increasing the risk of adverse drug
events, duplication of therapy, and drug-drug interactions.
Collecting this information before initiating new therapy allows
,the healthcare team to identify potential contraindications and
adjust treatment safely.
Option B is incorrect because the nurse should not
independently instruct a patient to discontinue OTC
medications without provider evaluation. Some OTC
medications may be necessary or require gradual
discontinuation.
Option C is incorrect because waiting for medication bottles
may unnecessarily delay essential treatment. The nurse should
begin reconciliation using patient interviews and available
records while obtaining additional verification.
Option D is incorrect because medications taken for years may
still significantly influence treatment decisions. Chronic
therapies, discontinued medications, and supplements are all
relevant.
Medication reconciliation is a major strategy for preventing
medication errors during transitions of care and requires
collaboration among nurses, pharmacists, providers, and
patients.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of medication reconciliation.
, • Identify components of a complete medication history.
• Recognize factors that increase medication-related risks in
older adults.
• Prioritize nursing interventions that reduce medication
errors.

Medication Reconciliation
Question 2
Clinical Scenario
A nurse is educating a newly licensed colleague about how
medications produce therapeutic effects. The nurse explains
that some medications activate receptors to produce a
response, while others prevent natural substances from binding
to receptors.
Question Stem
Which statement correctly describes the action of a medication
classified as a receptor antagonist?
A. It binds to receptors and stimulates the same response as the
body's natural chemical.
