FOUNDATIONS EXAM TEST BANK QUESTIONS AND
ANSWERS 2025
1. Which pharmacokinetic process is most affected by decreased hepatic function?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
✅ Correct Answer: C
Explanation: The liver is the primary site of drug metabolism. Impaired hepatic function
reduces metabolism, prolonging drug half-life and increasing toxicity risk.
2. A patient with renal failure requires dosage adjustments for which type of medication?
A. Drugs excreted unchanged by the kidneys
B. Drugs metabolized by the liver
C. Topical corticosteroids
D. Sublingual nitroglycerin
✅ Correct Answer: A
Explanation: Drugs primarily cleared unchanged through the kidneys accumulate when renal
function declines, requiring dosage reduction.
3. Which receptor type is primarily targeted by beta-blockers?
A. Alpha-1 adrenergic
B. Beta-adrenergic
C. Muscarinic

FOUNDATIONS EXAM TEST BANK QUESTIONS AND
ANSWERS 2025
D. Dopaminergic
✅ Correct Answer: B
Explanation: Beta-blockers block beta-adrenergic receptors in the heart, reducing heart rate,
myocardial contractility, and blood pressure.
4. Select all that apply: Common side effects of ACE inhibitors include:
🟩 A. Dry cough
🟩 B. Hyperkalemia
🟩 C. Hypoglycemia
⬜ D. Bradycardia
✅ Correct Answers: A, B
Explanation: ACE inhibitors cause dry cough from bradykinin accumulation and can increase
potassium retention.
5. Which of the following best describes a partial agonist?
A. Produces no effect when binding to a receptor
B. Produces the same maximal effect as a full agonist
C. Produces a smaller maximal response, even when all receptors are occupied
D. Blocks receptor activation
✅ Correct Answer: C
Explanation: Partial agonists bind to receptors but produce less than maximal activation, even at
high doses.

6. Which adverse effect is most associated with aminoglycoside antibiotics?
A. Hepatotoxicity
B. Ototoxicity and nephrotoxicity
C. Hypoglycemia
D. Hypotension
✅ Correct Answer: B
Explanation: Aminoglycosides (e.g., gentamicin) can cause renal tubular damage and hearing
loss due to toxicity.
7. Which of the following best defines first-pass metabolism?
A. Drug metabolism occurring in the kidney before systemic circulation
B. Degradation of oral drugs in the liver before reaching systemic circulation
C. Distribution of the drug in fatty tissues
D. The rate of absorption in the intestine
✅ Correct Answer: B
Explanation: First-pass metabolism occurs in the liver, reducing bioavailability of oral
medications.
8. Which medication is contraindicated in pregnancy due to teratogenicity?
A. Acetaminophen
B. ACE inhibitors
C. Penicillin
D. Heparin

FOUNDATIONS EXAM TEST BANK QUESTIONS AND
ANSWERS 2025
✅ Correct Answer: B
Explanation: ACE inhibitors can cause fetal renal malformation and death; they are
contraindicated in pregnancy.
9. Which neurotransmitter is primarily involved in Parkinson’s disease?
A. Acetylcholine
B. Dopamine
C. Serotonin
D. GABA
✅ Correct Answer: B
Explanation: Parkinson’s disease is caused by dopamine deficiency in the substantia nigra,
leading to motor dysfunction.
10. A nurse observes bleeding gums in a patient on warfarin. Which lab value should be
monitored?
A. BUN
B. PT/INR
C. Serum creatinine
D. AST/ALT
✅ Correct Answer: B
Explanation: PT/INR reflects warfarin’s anticoagulant effect; elevated levels indicate risk of
bleeding.
