Introduction to Pharmacology Nursing
Study Guide
Question 1
Clinical Scenario
A newly licensed nurse begins orientation on a medical-surgical
unit. During medication rounds, the nurse prepares to
administer an oral medication to a client. Before entering the
room, the preceptor asks, "What is the most effective strategy
to reduce medication administration errors?" The client is alert,
oriented, and has no urgent clinical concerns.
Question Stem
Which action should the nurse take to best promote safe
medication administration?
,A. Verify the medication using at least two patient identifiers
before administration.
B. Ask the client to state the medication's purpose before giving
it.
C. Compare the medication label with the medication
administration record after giving the medication.
D. Administer medications as quickly as possible to avoid delays
in treatment.
Correct Answer
Correct Answer: A. Verify the medication using at least two
patient identifiers before administration.
Detailed Rationale
Using at least two patient identifiers (such as the client's full
name and date of birth or medical record number) is a core
patient safety practice and one of the most effective methods
to prevent wrong-patient medication errors. Identification
should occur immediately before medication administration
and should never rely solely on room number or physical
appearance. This practice complements the "rights" of
medication administration and significantly reduces preventable
adverse events.
Option B is incorrect because discussing the medication's
purpose promotes patient education and engagement but does
,not reliably verify patient identity. Some clients may not know
why they receive certain medications.
Option C is incorrect because medication labels should be
compared with the medication administration record (MAR)
before administration, not afterward. Waiting until after
administration cannot prevent an error.
Option D is incorrect because rushing increases the likelihood
of medication errors. Nurses should organize their workflow
efficiently while carefully verifying medications and patient
identity.
Nurses should also encourage clients to participate in the
verification process when possible, report near misses
according to institutional policy, and minimize distractions
during medication preparation. Medication safety begins with
accurate patient identification and adherence to established
safety protocols.
Learning Objectives
After completing this question, the learner should be able to:
• Apply appropriate patient identification techniques before
medication administration.
• Identify strategies that reduce medication errors.
• Explain the nurse's responsibility for preventing wrong-
patient medication administration.

Question 2
Clinical Scenario
A 72-year-old client with hypertension, osteoarthritis, chronic
kidney disease stage 3, and type 2 diabetes takes prescriptions
from multiple providers. During admission, the nurse notices
the client has brought several prescription bottles, over-the-
counter pain relievers, and herbal supplements. The provider
requests a complete medication review before new medications
are prescribed.
Question Stem
Which nursing action is the priority?
A. Instruct the client to stop all herbal supplements
immediately.
B. Perform medication reconciliation using all prescription,
over-the-counter, and herbal products.
C. Discard medications that were prescribed by other providers.
D. Administer newly prescribed medications before reviewing
the home medication list.
