QUESTION TEST BANK
INSTRUCTIONS: This comprehensive final exam study guide covers all core topics for
NUR 306 (Pharmacology for Nursing Practice) including: Pharmacokinetics &
Pharmacodynamics, Autonomic Nervous System Drugs, Cardiovascular Medications,
Antibiotics & Antimicrobials, CNS Medications, Endocrine Medications, Respiratory
Drugs, GI Medications, Pain Management, Chemotherapy, Safety & Calculations, and
Patient Education. Each question includes the correct answer and a detailed
rationale to enhance understanding and exam preparation.
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Qs 1–25)
Q1: The nurse is administering a medication that is highly protein-bound.
Which statement best describes the effect of high protein binding on drug
action?
A) The drug will have a longer duration of action
B) The drug will be excreted more rapidly
C) The drug will have a shorter half-life
D) The drug will be less potent
Answer: A) The drug will have a longer duration of action
Rationale: Highly protein-bound drugs (e.g., warfarin, phenytoin) remain bound
to plasma proteins (mainly albumin) and are inactive while bound. Only the
unbound (free) fraction is pharmacologically active. High protein binding
means less free drug available, which prolongs the drug's duration of action
because the bound drug acts as a reservoir, slowly releasing active drug.

,Q2: Which phase of pharmacokinetics involves the movement of a drug from the
site of administration into the bloodstream?
A) Distribution
B) Absorption
C) Metabolism
D) Excretion
Answer: B) Absorption
Rationale: Absorption is the process by which a drug moves from its site of
administration into the bloodstream. Distribution is the movement of drug from
the bloodstream to tissues; metabolism is the biotransformation of the drug;
excretion is the removal of the drug from the body.
Q3: The nurse is caring for a patient with liver disease. Which phase of
pharmacokinetics is most likely affected?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Answer: C) Metabolism
Rationale: The liver is the primary site of drug metabolism (biotransformation).
Liver disease can impair metabolism, leading to drug accumulation, toxicity,
and prolonged effects. Dosage adjustments are often needed for patients with
hepatic impairment.
Q4: A medication has a half-life of 4 hours. How long will it take for the
drug to reach steady state?
2|Page
,A) 8 hours
B) 12 hours
C) 16 hours
D) 20 hours
Answer: D) 20 hours
Rationale: Steady state is achieved after approximately 4-5 half-lives of
regular dosing. With a half-life of 4 hours, steady state is reached in
approximately 16-20 hours (4 half-lives = 16 hours; 5 half-lives = 20 hours).
Q5: The nurse is administering a medication that is a weak acid. Which
statement best describes where this drug will be absorbed?
A) It will be absorbed in the stomach, where the pH is acidic
B) It will be absorbed in the small intestine, where the pH is alkaline
C) It will be absorbed equally in all parts of the GI tract
D) It will not be absorbed
Answer: A) It will be absorbed in the stomach, where the pH is acidic
Rationale: Weak acids are non-ionized (lipid-soluble) in acidic environments
(stomach), which allows them to cross cell membranes and be absorbed. Weak
bases are non-ionized in alkaline environments (small intestine). This is the
principle of pH partitioning.
Q6: Which route of administration has the fastest onset of action?
A) Oral
B) Intramuscular
C) Subcutaneous
D) Intravenous
3|Page
, Answer: D) Intravenous
Rationale: Intravenous (IV) administration delivers the drug directly into the
bloodstream, providing the fastest onset of action (immediate). Oral
administration requires absorption through the GI tract, which is slower. IM
and SC routes also require absorption from the injection site.
Q7: The nurse is administering a drug that undergoes first-pass metabolism.
Which route of administration would avoid this effect?
A) Oral
B) Sublingual
C) Rectal
D) Both B and C
Answer: D) Both B and C
Rationale: Sublingual and rectal routes partially or completely bypass the
first-pass effect because the drug is absorbed directly into the systemic
circulation, avoiding the portal circulation and the liver. Oral medications
are absorbed into the portal circulation and pass through the liver before
reaching systemic circulation.
Q8: The therapeutic index of a drug refers to:
A) The ratio of the drug's toxic dose to its therapeutic dose
B) The amount of drug needed to produce a therapeutic effect
C) The time it takes for the drug to be eliminated
D) The percentage of drug that is protein-bound
Answer: A) The ratio of the drug's toxic dose to its therapeutic dose
Rationale: The therapeutic index (TI) is the ratio of the lethal dose (LD50)
