1 Introduction
This study guide is designed to prepare nursing students for the ATI Pharmacology
Proctored Exam 2023 Form A. It includes 100 carefully selected questions with detailed
answers and rationales, covering drug classifications, pharmacokinetics, dosage calcula-
tions, adverse effects, patient education, and nursing interventions. The content is concise,
relevant, and aligned with exam standards to ensure comprehensive preparation.
2 Pharmacology Questions and Answers
2.1 Drug Classifications and Mechanisms
1. A nurse is teaching a client about metformin. What is the primary ac-
tion of this medication?
Answer: Decreases hepatic glucose production and increases insulin sensitivity.
Rationale: Metformin, a biguanide, reduces gluconeogenesis in the liver and en-
hances insulin-mediated glucose uptake in peripheral tissues, making it a first-line
treatment for type 2 diabetes mellitus.
2. A client is prescribed lisinopril for hypertension. What is the mechanism
of action?
Answer: Inhibits angiotensin-converting enzyme (ACE), reducing angiotensin II
levels.
Rationale: Lisinopril, an ACE inhibitor, blocks the conversion of angiotensin I to
angiotensin II, causing vasodilation, reduced blood pressure, and decreased cardiac
workload.
3. A nurse is administering digoxin to a client with heart failure. What
should be monitored to prevent toxicity?
Answer: Serum potassium levels and apical heart rate.
Rationale: Hypokalemia potentiates digoxin toxicity by increasing cardiac sensi-
tivity to the drug, and a heart rate below 60 bpm may indicate toxicity, necessitating
dose withholding.
4. A client is receiving vancomycin for a systemic infection. What adverse
effect should be monitored?
Answer: Red man syndrome.
Rationale: Rapid infusion of vancomycin can trigger histamine release, causing
flushing, rash, and hypotension, known as red man syndrome, which can be miti-
gated by slowing the infusion rate.
5. A nurse is teaching a client about albuterol. What is the primary ther-
apeutic effect?
Answer: Bronchodilation.
Rationale: Albuterol, a beta-2 adrenergic agonist, relaxes bronchial smooth mus-
cles, improving airflow in conditions such as asthma or chronic obstructive pul-
monary disease (COPD).
6. A client is prescribed warfarin. What is the primary purpose of this
medication?
