SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions
1-25)
Question 1: A patient is prescribed a drug that is a weak base with a pKa of 8.4. In
which part of the body will this drug be MOST highly ionized?


A) Small intestine (pH 7.4)
B) Stomach (pH 1.5–3.5)
C) Blood (pH 7.35–7.45)
D) Urine (pH 5.0–8.0)


<details> <summary><b>Answer & Rationale</b></summary> **Correct
Answer: B) Stomach (pH 1.5–3.5)**
Rationale: Weak bases are more ionized in acidic environments (low pH). Ionized
drugs are poorly absorbed across lipid membranes. Weak acids are better absorbed
in the stomach; weak bases are better absorbed in the small intestine. This principle
is crucial for understanding drug absorption and urinary excretion manipulation .

Question 2: Which pharmacokinetic process is MOST affected by first-pass
metabolism?


A) Distribution
B) Metabolism
C) Oral absorption
D) Renal excretion
