Questions and Answers (PDF)
1. Which pharmacokinetic process describes movement of a drug from the
bloodstream into body tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: B. Distribution
Rationale: Distribution is the movement of a drug from systemic circulation into
tissues and body fluids.
2. Which organ is primarily responsible for phase I drug metabolism?
A. Kidney
B. Liver
C. Heart
D. Spleen
Answer: B. Liver
Rationale: Hepatic CYP450 enzymes perform much of phase I metabolism.
3. Which route provides 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
Answer: C. Intravenous
Rationale: IV administration places the entire dose directly into systemic
circulation.
,4. What does a drug's half-life represent?
A. Time required for absorption
B. Time required for 50% of the drug to be eliminated
C. Time required for peak concentration
D. Time required for metabolism to begin
Answer: B. Time required for 50% of the drug to be eliminated
Rationale: Half-life is the time needed for plasma drug concentration to decrease
by 50%.
5. Which pharmacodynamic concept describes the maximum effect a drug can
produce?
A. Potency
B. Efficacy
C. Affinity
D. Bioavailability
Answer: B. Efficacy
Rationale: Efficacy refers to the maximum therapeutic effect achievable.
6. A partial agonist primarily:
A. Produces no receptor activity
B. Produces a submaximal response
C. Permanently blocks receptors
D. Destroys receptors
Answer: B. Produces a submaximal response
Rationale: Partial agonists activate receptors but have less intrinsic activity than
full agonists.
7. Which drug interaction occurs when one drug increases CYP450 metabolism
of another?
A. Enzyme inhibition
B. Enzyme induction
C. Protein binding
D. Competitive antagonism
Answer: B. Enzyme induction
,Rationale: Enzyme induction can increase metabolism and reduce concentrations
of affected drugs.
8. Which factor can increase the free fraction of a highly protein-bound drug?
A. Increased albumin
B. Hypoalbuminemia
C. Increased renal function
D. Increased absorption
Answer: B. Hypoalbuminemia
Rationale: Less albumin means less protein binding and potentially more active
free drug.
9. Which laboratory value is particularly important when monitoring warfarin?
A. aPTT
B. INR
C. Troponin
D. HbA1c
Answer: B. INR
Rationale: INR is used to monitor warfarin anticoagulant effect.
10. Which medication is a direct oral factor Xa inhibitor?
A. Warfarin
B. Apixaban
C. Clopidogrel
D. Aspirin
Answer: B. Apixaban
Rationale: Apixaban directly inhibits factor Xa.
11. A patient taking an ACE inhibitor develops facial swelling. What is the
priority concern?
A. Hyperglycemia
B. Angioedema
C. Constipation
D. Hypokalemia
Answer: B. Angioedema
, Rationale: ACE inhibitors can cause potentially life-threatening angioedema
involving the airway.
12. Which adverse effect is characteristic of ACE inhibitors?
A. Dry cough
B. Severe constipation
C. Hearing loss
D. Hypoglycemia
Answer: A. Dry cough
Rationale: Bradykinin accumulation can cause a persistent dry cough.
13. Which medication class is associated with hyperkalemia?
A. ACE inhibitors
B. Loop diuretics
C. Thiazide diuretics
D. Osmotic diuretics
Answer: A. ACE inhibitors
Rationale: Reduced aldosterone activity decreases potassium excretion.
14. Which drug is a calcium-channel blocker commonly used for hypertension?
A. Amlodipine
B. Lisinopril
C. Losartan
D. Hydrochlorothiazide
Answer: A. Amlodipine
Rationale: Amlodipine is a dihydropyridine calcium-channel blocker.
15. Which adverse effect commonly occurs with amlodipine?
A. Peripheral edema
B. Severe hypoglycemia
C. Dry cough
D. Hyperkalemia
Answer: A. Peripheral edema
Rationale: Dihydropyridine calcium-channel blockers commonly cause peripheral
edema.
