Graded A+
1. Which pharmacokinetic process describes the movement of a drug from the
gastrointestinal tract into systemic circulation?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Answer: B. Absorption
Rationale: Absorption is the movement of a drug from its administration site into systemic
circulation. Oral medications are commonly absorbed through the gastrointestinal tract.
2. Which route of administration provides 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intramuscular
D. Intravenous
Answer: D. Intravenous
Rationale: IV administration delivers the medication directly into systemic circulation, resulting
in complete bioavailability.
3. What is the primary effect of first-pass metabolism?
A. It increases oral drug absorption
B. It decreases the amount of drug reaching systemic circulation
,C. It prevents renal excretion
D. It increases protein binding
Answer: B. It decreases the amount of drug reaching systemic circulation
Rationale: Drugs absorbed from the gastrointestinal tract may undergo hepatic metabolism
before reaching systemic circulation, reducing their bioavailability.
4. Which patient factor can significantly alter drug pharmacokinetics in older adults?
A. Increased renal function
B. Increased hepatic blood flow
C. Reduced renal clearance
D. Increased total body water
Answer: C. Reduced renal clearance
Rationale: Aging is associated with decreased renal function in many patients, which can
prolong the half-life of renally eliminated medications.
5. A medication has a narrow therapeutic index. What does this mean?
A. The medication is always safe
B. There is a small difference between therapeutic and toxic concentrations
C. The medication has poor absorption
D. The medication has no drug interactions
Answer: B. There is a small difference between therapeutic and toxic concentrations
Rationale: Drugs with a narrow therapeutic index require careful dosing and monitoring
because relatively small concentration changes may cause toxicity.
6. Which laboratory test is most useful when assessing renal clearance before prescribing a
renally eliminated medication?
A. Serum creatinine/eGFR
B. ALT
C. Hemoglobin
D. Bilirubin only
,Answer: A. Serum creatinine/eGFR
Rationale: Renal function is commonly assessed using serum creatinine and estimated
glomerular filtration rate.
7. Which patient is at greatest risk for adverse drug reactions?
A. Healthy young adult taking one medication
B. Older adult taking multiple medications
C. Healthy adolescent taking one short-term medication
D. Adult taking only a multivitamin
Answer: B. Older adult taking multiple medications
Rationale: Age-related physiologic changes and polypharmacy increase the risk of adverse drug
reactions and drug interactions.
8. Which pharmacokinetic process involves enzymatic alteration of a drug?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: C. Metabolism
Rationale: Drug metabolism chemically modifies medications, primarily through hepatic
enzymes.
9. Which organ is the major site of drug metabolism?
A. Kidney
B. Liver
C. Heart
D. Spleen
Answer: B. Liver
Rationale: The liver contains numerous enzymes, including CYP450 enzymes, responsible for
metabolism of many medications.
, 10. Which organ is the major route of elimination for many medications and metabolites?
A. Kidney
B. Pancreas
C. Thyroid
D. Lung
Answer: A. Kidney
Rationale: Renal excretion through glomerular filtration, secretion, and reabsorption is a major
route of drug elimination.
Cardiovascular Pharmacology
11. Which medication class is commonly used as first-line therapy for uncomplicated
hypertension?
A. Thiazide diuretics
B. Class I antiarrhythmics
C. Nitrates
D. Digoxin
Answer: A. Thiazide diuretics
Rationale: Thiazide-type diuretics are among the recommended first-line antihypertensive
medication classes.
12. Which electrolyte abnormality can occur with hydrochlorothiazide?
A. Hyperkalemia
B. Hypokalemia
C. Hypermagnesemia
D. Hypernatremia in every patient
Answer: B. Hypokalemia
Rationale: Thiazide diuretics increase urinary potassium excretion and can cause hypokalemia.
13. Which adverse effect is associated with ACE inhibitors?
