NUR 210 EXAM 1 – Foundations of Pharmacology
Section 1: Pharmacokinetics & Pharmacodynamics
Q1. What is the primary site of drug metabolism?
- Correct Answer: Liver
- Rationale: The liver is the primary site of drug metabolism (biotransformation).
The kidneys are the primary site of drug excretion .
Q2. What is drug metabolism (biotransformation)?
- Correct Answer: The process of the body chemically changing a drug into a
form that can be excreted
1
,- Rationale: Metabolism occurs primarily in the liver via the cytochrome P450
enzyme system. It converts lipid-soluble drugs into water-soluble compounds for
excretion .
Q3. Half-life (t½) is defined as:
- A) The time it takes for a drug to reach peak concentration
- B) The time it takes for the amount of drug in the body to be reduced by half
- C) The time it takes for a drug to be completely eliminated
- D) The time it takes for a drug to be absorbed
- Correct Answer: B
- Rationale: Half-life is the time required for the serum concentration of a drug to
decrease by 50%. It determines the dosing interval .
Q4. A loading dose is:
- A) A small initial dose
- B) A large initial dose used for drugs with long half-lives
- C) The maintenance dose given daily
- D) The dose given at bedtime
- Correct Answer: B
- Rationale: A loading dose is a large initial dose used to rapidly achieve
therapeutic drug levels for drugs with long half-lives .
Q5. Pharmacodynamics is the study of:
2
, - A) How the body affects the drug
- B) How drugs affect the body
- C) Drug movement through the body
- D) Drug excretion from the body
- Correct Answer: B
- Rationale: Pharmacodynamics is the study of what drugs do to the body—the
drug's mechanisms of action and effects on the body .
Q6. Drug excretion (elimination) routes include all of the following EXCEPT:
- A) Kidneys (urine)
- B) Liver (bile)
- C) Bone marrow
- D) Lungs
- Correct Answer: C
- Rationale: Drug excretion occurs through kidneys (urine), liver (bile), feces,
lungs, saliva, sweat, and breast milk. Bone marrow is not a primary excretion route
.
Q7. Renal function tests used to assess drug excretion include:
- A) Creatinine, BUN, and GFR
- B) AST, ALT, and Bilirubin
- C) WBC, RBC, and Platelets
- D) Glucose, Protein, and Ketones
