# Section 5.1: Pharmacokinetics & Pharmacodynamics (20 Questions)
**Question 1.**
A nurse practitioner is prescribing a medication that is a weak acid.
Which statement best describes the absorption of this medication in the
stomach?
A) Absorption is decreased because the stomach is acidic
B) Absorption is increased because the stomach is acidic
C) Absorption is unchanged regardless of gastric pH
D) Absorption depends only on blood flow to the stomach
**Answer:** B) Absorption is increased because the stomach is acidic
**Rationale:** Weak acids are non-ionized (lipid-soluble) in acidic
environments, allowing passive diffusion across gastric mucosa. Weak
bases are better absorbed in the alkaline small intestine. (pH partitioning
principle) .
**Question 2.**
A patient with liver cirrhosis has decreased albumin levels. How will
this affect the distribution of a highly protein-bound medication?
A) Decreased free drug concentration, increased drug effect
B) Increased free drug concentration, increased risk of toxicity
C) No change in drug distribution
D) Decreased drug half-life
,3|Page
**Answer:** B) Increased free drug concentration, increased risk of
toxicity
**Rationale:** Low albumin reduces protein binding sites, increasing
free (active) drug concentration. This increases both therapeutic and
toxic effects. Dose reduction may be needed .
Question 3.**
Which phase of drug metabolism (biotransformation) typically results in
conjugation and increased water solubility for renal excretion?
A) Phase I (oxidation, reduction, hydrolysis)
B) Phase II (conjugation: glucuronidation, acetylation, sulfation)
C) Phase III (active transport)
D) Absorption phase
**Answer:** B) Phase II
**Rationale:** Phase II reactions add polar groups (glucuronide, sulfate,
acetyl) to Phase I metabolites or parent drugs, increasing water solubility
for excretion. Phase I often prepares drugs for Phase II .
Question 4.**
A patient is taking a drug with a narrow therapeutic index. The nurse
practitioner understands that this means:
A) The drug has a wide safety margin
B) The drug has a small difference between therapeutic and toxic doses
, 4|Page
C) The drug is safe for use in pregnancy
D) The drug requires no monitoring
**Answer:** B) The drug has a small difference between therapeutic
and toxic doses
**Rationale:** Narrow therapeutic index drugs (e.g., warfarin, digoxin,
lithium, phenytoin) require careful monitoring because small dose
changes can cause toxicity or therapeutic failure .
Question 5.**
The half-life of a drug is 4 hours. Approximately how long will it take
for the drug to reach steady state?
A) 8 hours
B) 12 hours
C) 20 hours
D) 24 hours
**Answer:** C) 20 hours
**Rationale:** Steady state is achieved after approximately 4-5 half-
lives. 4 hours × 5 = 20 hours. This principle applies to both reaching
steady state and drug elimination after discontinuation .
Question 6.**
Which cytochrome P450 enzyme is responsible for metabolizing the
largest number of drugs?
A) CYP1A2
