CMS PHARMACOLOGY PROCTORED EXAM
ACTUAL EXAM PAPER 2026 QUESTIONS
WITH ANSWERS GRADED A+
⩥ Absorption. Answer: How drug enters bloodstream; affected by route,
blood flow, GI motility, food, pH, and formulation (IR vs ER).
⩥ IV route absorption. Answer: No absorption step—drug is
immediately in bloodstream → fastest onset, highest risk for error.
⩥ First-pass effect. Answer: Oral drugs can be metabolized/inactivated
by liver before reaching circulation → less bioavailability.
⩥ Bioavailability. Answer: Percent of drug that reaches systemic
circulation; IV = 100%.
⩥ Distribution. Answer: Movement of drug through body; influenced by
blood flow, body fat/water, capillary permeability, and protein binding.
⩥ Protein binding (albumin). Answer: Bound drug is inactive; only free
drug works. Low albumin or displacement by another drug ↑ free drug
→ toxicity risk.
, ⩥ Blood-brain barrier. Answer: Limits drug entry to CNS; lipophilic
drugs cross easier. Inflammation (meningitis) can increase penetration.
⩥ Placental transfer. Answer: Many drugs cross placenta; teratogenic
risk depends on gestational age and drug properties.
⩥ Metabolism (biotransformation). Answer: Mostly liver; converts drugs
to metabolites; impaired liver function → slower metabolism → toxicity
risk.
⩥ Prodrug. Answer: Inactive form converted to active in body (often
liver). Liver impairment can reduce effect.
⩥ Excretion. Answer: Mostly kidneys; renal impairment → drug
accumulates → toxicity risk.
⩥ Half-life (t½). Answer: Time for blood level to drop by 50%. Takes
~4-5 half-lives to reach steady state.
⩥ Steady state. Answer: Stable drug level achieved after multiple doses.
⩥ Peak. Answer: Highest concentration—when side effects/toxicity
most likely.
