Exam Introduction
Purpose:
This exam assesses the nurse’s understanding of drug absorption, distribution, metabolism,
excretion, and pharmacodynamic effects, as well as factors affecting drug therapy in patients.
Instructions:
1. Read each question carefully and select the best answer (A, B, C, or D).
2. Each question is worth 1 point; 100 points total.
3. Complete the exam within 2 hours.
4. Answers and rationales are provided for learning reinforcement.

Learning Outcome:
Demonstrates the ability to predict drug movement and action in the body, recognize factors
influencing patient response, and apply pharmacology principles to safe nursing care.
Section 1: Drug Absorption & Bioavailability (Questions 1–25)
Q1. Which route of administration has the fastest onset of
action?
A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
Answer: C
Rationale:
Intravenous administration delivers the drug directly into the
bloodstream, providing immediate bioavailability and the
fastest onset. Oral, subcutaneous, and intramuscular routes
require absorption first, delaying onset.
Q2. First-pass metabolism primarily affects which route of
drug administration?
A. Intravenous
B. Oral
,3
C. Subcutaneous
D. Topical
Answer: B
Rationale:
Drugs absorbed via the gastrointestinal tract pass through the
liver before reaching systemic circulation, leading to significant
metabolism and reduced bioavailability (first-pass effect). IV,
subcutaneous, and topical routes bypass this.
Q3. Which factor can decrease the absorption of oral
medications?
A. Increased gastric emptying
B. High-fat meal
C. Normal intestinal motility
D. Alkaline gastric pH
Answer: D
Rationale:
Alkaline gastric pH can reduce the solubility of weakly acidic
drugs, decreasing their absorption. High-fat meals may delay
absorption but can also enhance absorption for some lipophilic
drugs.

Q4. A nurse knows that lipid-soluble drugs are absorbed
primarily by:
A. Facilitated diffusion
B. Active transport
C. Passive diffusion
D. Endocytosis
Answer: C
Rationale:
Lipid-soluble drugs cross cell membranes mainly via passive
diffusion, moving from high to low concentration without
energy expenditure. Active transport and facilitated diffusion
are used by hydrophilic or large molecules.
Q5. The term “bioavailability” refers to:
A. The total dose administered
B. The fraction of drug that reaches systemic circulation
C. The drug’s half-life
D. The rate of metabolism
Answer: B
Rationale:
Bioavailability is the percentage of an administered dose that
reaches systemic circulation intact, reflecting the efficiency of
absorption and first-pass metabolism.
