RN Pharmacology Practice Exam
2024 Content Alignment | 70 Original Questions
Independent HESI/NCLEX-style practice format with answers and rationales
Unofficial educational study material. These are original practice questions, not actual HESI or
NCLEX exam items. No HESI/Elsevier or NCSBN endorsement, professor verification, official
score, or certification credit is claimed.
The question set targets 2024 medication-safety and pharmacology references, including the 2024
ADA Standards of Care, the 2024 ISMP High-Alert Medications list, and the NCSBN NCLEX-RN
Pharmacological and Parenteral Therapies test-plan domain. Confirm current product labeling,
patient-specific parameters, and institutional protocols before clinical use.
Selected references: NCSBN NCLEX-RN Test Plan; American Diabetes Association, Standards of
Care in Diabetes, 2024; ISMP List of High-Alert Medications in Acute Care Settings (2024).
For education and review only; not a substitute for nursing education, clinical judgment, current
drug references, or local protocols.

Administration
Q1: A nurse explains that drug absorption is the process of:
A. movement of a medication from its administration site into the systemic circulation.
[CORRECT]
B. movement of a medication from the bloodstream into body tissues.
C. chemical alteration of a medication, primarily by the liver.
D. removal of a medication and its metabolites from the body.
Correct Answer: A
Rationale: Absorption moves a drug from its administration site into systemic circulation.
Distribution, metabolism, and excretion are separate pharmacokinetic processes.
Q2: The half-life of a medication is the time required for:
A. the medication to reach its maximum therapeutic effect.
B. the plasma concentration of the medication to decrease by approximately 50%.
[CORRECT]
C. the medication to reach peak concentration after a dose.
D. the body to absorb the entire administered dose.
Correct Answer: B
Rationale: Half-life describes the time for the plasma concentration to fall by about one half. It
does not identify the time to peak concentration or the duration of clinical effect in every
patient.
Q3: An older adult with chronic kidney disease has a new prescription for a medication
cleared mainly by the kidneys. What should the nurse review before the first dose?
A. The client's age alone, then give the standard dose without further review.
B. Current renal function and the prescribed dose, clarifying the plan if the dose may not be
adjusted for impaired clearance. [CORRECT]
C. A liver enzyme result only, because renal function does not affect drug exposure.
D. The client's weight only, then increase the dose to compensate for kidney disease.
Correct Answer: B
Rationale: Reduced renal clearance can increase drug exposure and toxicity, so current
kidney function and dose appropriateness should be reviewed. Age or weight alone cannot
substitute for an individualized renal assessment.
