NUR 2407 PHARMACOLOGY QUIZ 1
COMPREHENSIVE STUDY SET
QUESTIONS AND ANSWERS
1. Which term describes the study of what the body does to a drug, including absorption,
distribution, metabolism, and excretion?
A. Pharmacodynamics
B. Pharmacotherapeutics
C. Pharmacokinetics
D. Pharmacognosy
Answer: C
Conceptual Explanation: Pharmacokinetics refers to the movement of drugs through the
body (Absorption, Distribution, Metabolism, Excretion). Pharmacodynamics is what the
drug does to the body.
2. A patient is taking a drug that has a high first-pass effect. Which route of administration
will result in the lowest bioavailability?
A. Intravenous
,B. Sublingual
C. Rectal
D. Oral
Answer: D
Conceptual Explanation: Oral drugs are absorbed in the GI tract and carried to the liver
via the hepatic portal vein, where they are metabolized before reaching systemic
circulation (first-pass effect).
3. What is the primary site for drug metabolism in the human body?
A. Kidneys
B. Liver
C. Lungs
D. Small Intestine
Answer: B
Conceptual Explanation: The liver is the main organ responsible for the
biotransformation or metabolism of drugs, primarily through the cytochrome P-450
enzyme system.
4. A drug has a half-life of 4 hours. If a patient takes 200mg at 12:00 PM, how much drug will
remain in the body at 8:00 PM?
A. 100 mg
, B. 25 mg
C. 50 mg
D. 0 mg
Answer: C
Conceptual Explanation: After one half-life (4 hours at 4:00 PM), 100mg remains. After a
second half-life (another 4 hours at 8:00 PM), 50mg remains.
5. Which protein is the most important for drug binding in the blood?
A. Hemoglobin
B. Albumin
C. Globulin
D. Fibrinogen
Answer: B
Conceptual Explanation: Albumin is the most common blood protein and the primary
protein to which drugs bind. Only unbound (free) drug is pharmacologically active.
6. A patient with end-stage renal disease is at risk for drug toxicity primarily because of which
pharmacokinetic phase?
A. Absorption
B. Distribution
