Section One: Questions 1–100
1. A patient with chronic kidney disease requires an adjustment in their medication
dosage. Which pharmacokinetic process is primarily affected by a decrease in
glomerular filtration rate?
,A. Absorption
B. Distribution
C. Metabolism
D. Excretion
🟢 D. Excretion
🔴 Explanation: Glomerular filtration is a key component of renal excretion. A decrease in
the filtration rate directly reduces the body's ability to eliminate drugs and their metabolites
through the urine.
2. Which of the following describes the "first-pass effect" in oral drug administration?
A. The initial rapid distribution of a drug to highly vascular organs
B. The metabolism of a drug by the liver before it reaches systemic circulation
C. The binding of a drug to plasma proteins upon entering the bloodstream
D. The movement of a drug from the stomach into the small intestine
🟢 B. The metabolism of a drug by the liver before it reaches systemic circulation
🔴 Explanation: Drugs absorbed through the gastrointestinal tract travel via the portal
vein to the liver, where significant metabolism can occur, reducing the bioavailability of the
drug before it reaches the rest of the body.
, 3. An elderly patient is prescribed a lipophilic medication. How does the increased body
fat percentage in geriatric patients typically affect the distribution of this drug?
A. Decreased volume of distribution and increased plasma concentration
B. Increased volume of distribution and prolonged half-life
C. Reduced half-life due to rapid sequestration in adipose tissue
D. Increased renal clearance of the drug
🟢 B. Increased volume of distribution and prolonged half-life
🔴 Explanation: Lipophilic drugs distribute extensively into adipose tissue. In elderly
patients with higher fat ratios, the volume of distribution increases, which can lead to a
longer half-life as the drug is slowly released back into the blood.
4. A nurse practitioner is selecting a beta-blocker for a patient with a history of severe
asthma. Which agent is the most appropriate choice to minimize the risk of
bronchospasm?
A. Propranolol
B. Nadolol
C. Metoprolol
D. Timolol
, 🟢 C. Metoprolol
🔴 Explanation: Metoprolol is a cardioselective beta-1 antagonist. At standard doses, it
has a lower affinity for beta-2 receptors in the lungs compared to non-selective agents like
Propranolol, making it safer for asthmatic patients.
5. Which mechanism of action is characteristic of Lisinopril?
A. Inhibition of the conversion of Angiotensin I to Angiotensin II
B. Blocking the binding of Angiotensin II to its receptors
C. Direct inhibition of renin release from the kidneys
D. Promoting the excretion of sodium via the distal tubule
🟢 A. Inhibition of the conversion of Angiotensin I to Angiotensin II
🔴 Explanation: Lisinopril is an ACE inhibitor that prevents the Angiotensin-Converting
Enzyme from producing Angiotensin II, a potent vasoconstrictor.
6. A patient taking Warfarin is started on Amiodarone. What is the expected interaction
between these two drugs?
A. Decreased anticoagulant effect of Warfarin
B. Increased risk of bleeding due to inhibition of CYP2C9
C. Reduced absorption of Amiodarone
D. Immediate neutralization of Warfarin by Amiodarone
