Question 1
Clinical Scenario
A 22-year-old nursing student begins a clinical rotation on a medical-
surgical unit. During medication administration, the instructor asks the
student to explain the purpose of pharmacology in nursing practice. The
student states that medications should always be administered exactly
as prescribed without further assessment.
Question Stem
Which response by the nursing instructor is most appropriate?
A. Nurses should administer medications exactly as prescribed without
evaluating the client.
B. Nurses are responsible for understanding how medications work,
monitoring for therapeutic and adverse effects, and evaluating client
responses.
,C. Nurses should rely on the pharmacist to determine whether
medications are safe for the client.
D. Nurses only need to know the medication dose and route before
administration.
Correct Answer
B. Nurses are responsible for understanding how medications work,
monitoring for therapeutic and adverse effects, and evaluating client
responses.
Detailed Rationale
Pharmacology is fundamental to safe nursing practice because nurses
are responsible not only for administering medications but also for
assessing whether a medication is appropriate at the time of
administration, monitoring for expected therapeutic responses,
identifying adverse effects, recognizing contraindications, and educating
patients. Safe medication administration requires clinical judgment
before, during, and after giving medications. Nurses should verify
allergies, laboratory values, vital signs, potential drug interactions, and
the patient's current condition before administration.
Option A is incorrect because medication administration is never
automatic; assessment may reveal reasons to withhold a medication or
notify the provider.
Option C is incorrect because pharmacists are valuable members of the
healthcare team, but nurses remain accountable for safely
administering medications and monitoring patient outcomes.
,Option D is incorrect because knowledge of dose and route alone is
insufficient. Nurses must understand indications, contraindications,
expected outcomes, adverse reactions, and monitoring requirements.
Developing pharmacology knowledge improves patient safety, reduces
medication errors, and supports evidence-based clinical decision-
making.
Learning Objectives
After completing this question, the learner should be able to:
• Describe the nurse's role in safe medication administration.
• Explain why pharmacology knowledge is essential for clinical
judgment.
• Identify nursing responsibilities after medication administration.
Medication Safety Focus: Medication administration
Question 2
Clinical Scenario
A nurse prepares to administer a newly prescribed medication to a
hospitalized client. Before administration, the nurse reviews the
electronic medication administration record, verifies the client's
identification using two identifiers, confirms allergies, and checks the
medication label three separate times.
Question Stem
Which medication safety principle is the nurse primarily demonstrating?
, A. Medication reconciliation
B. The rights of medication administration
C. Therapeutic drug monitoring
D. Pharmacokinetic evaluation
Correct Answer
B. The rights of medication administration
Detailed Rationale
The nurse is applying the principles commonly known as the rights of
medication administration, which are foundational to medication safety.
These include verifying the correct patient, medication, dose, route,
time, documentation, indication, response, and the patient's right to
refuse (institutional policies may vary regarding the total number of
rights). Checking the medication label multiple times and confirming
patient identity with two identifiers significantly reduce medication
errors.
Option A is incorrect because medication reconciliation focuses on
comparing medication lists during transitions of care to prevent
omissions, duplications, and interactions.
Option C is incorrect because therapeutic drug monitoring involves
measuring serum drug concentrations for medications with narrow
therapeutic ranges, such as vancomycin or digoxin.
Option D is incorrect because pharmacokinetic evaluation refers to how
the body absorbs, distributes, metabolizes, and eliminates medications
rather than routine bedside medication administration.
