20 ATI & NGN-Style NCLEX Questions with Detailed
Rationales
Question 1
Clinical Scenario
A 20-year-old nursing student begins a pharmacology course
and asks the nurse educator why medications can produce both
beneficial and harmful effects. The student also asks why nurses
must understand pharmacology rather than simply administer
medications prescribed by providers.
,Question Stem
Which response by the nurse educator is most appropriate?
A. Pharmacology helps nurses understand how medications
interact with the body so they can administer drugs safely and
recognize therapeutic and adverse effects.
B. Pharmacology is primarily used to memorize medication
names and standard dosages.
C. Pharmacology is mainly the responsibility of pharmacists, so
nurses only need to follow medication administration
schedules.
D. Pharmacology is important only when administering high-
alert medications.
Correct Answer
Correct Answer: A. Pharmacology helps nurses understand
how medications interact with the body so they can
administer drugs safely and recognize therapeutic and adverse
effects.
Detailed Rationale
Pharmacology is the study of medications and their effects on
the body, including indications, mechanisms of action,
therapeutic uses, adverse effects, contraindications,
interactions, metabolism, elimination, and monitoring
,requirements. Nurses apply pharmacologic knowledge during
every step of medication administration—from assessing
whether a medication is appropriate to evaluating its
effectiveness and identifying complications. Understanding
pharmacology supports clinical judgment, reduces medication
errors, and promotes patient safety.
Option A is correct because it accurately reflects the nurse's
professional responsibility to understand how medications work
and how to monitor patients for both expected and unexpected
responses.
Option B is incorrect because memorizing drug names and
doses alone is insufficient. Safe nursing practice requires
assessment, interpretation, and evaluation.
Option C is incorrect because medication safety is a shared
responsibility among prescribers, pharmacists, and nurses.
Nurses perform ongoing patient assessments before and after
medication administration.
Option D is incorrect because pharmacologic knowledge is
necessary for every medication, not only high-alert drugs. Even
commonly prescribed medications may produce serious
adverse effects or interactions.
Safe medication administration depends on integrating
pharmacology knowledge with patient assessment, clinical
reasoning, and evidence-based nursing care.
, Learning Objectives
After completing this question, the learner should be able to:
• Explain the purpose of pharmacology in nursing practice.
• Describe the nurse's role in medication safety.
• Differentiate medication administration from
pharmacologic clinical judgment.
Medication Safety Focus
Medication administration
Question 2
Clinical Scenario
A 72-year-old woman is admitted with community-acquired
pneumonia. Her medical history includes chronic kidney
disease, hypertension, and type 2 diabetes mellitus. Before
administering newly prescribed medications, the nurse
performs a comprehensive medication reconciliation.
Question Stem
Which action best demonstrates appropriate medication
reconciliation?
