NURS 6521 – Advanced Pharmacology
Comprehensive 200-Question Exam
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1-30)
QUESTION 1:
First-pass metabolism occurs primarily in which organ?
A. Kidneys
B. Lungs
C. Liver
D. Intestines
ANSWER:
C. Liver
RATIONALE:
First-pass metabolism occurs when a drug is metabolized in the liver before reaching systemic
circulation, reducing its bioavailability. Drugs administered orally pass through the hepatic portal
system and undergo metabolism by hepatic enzymes, particularly the CYP450 system. This is why
some drugs require higher oral doses than intravenous doses to achieve therapeutic effects. The
kidneys are responsible for drug excretion, not first-pass metabolism. The lungs are involved in the
elimination of volatile drugs but are not the primary site of first-pass metabolism. Intestinal
metabolism occurs to a lesser extent through enteric enzymes and the gut microbiome, but the liver
is the primary site .
QUESTION 2:
Bioavailability refers to which of the following?
A. The distribution of a drug to target tissues
B. The amount of active drug that reaches systemic circulation
C. The rate at which a drug is metabolized
D. The time required for drug excretion
ANSWER:
B. The amount of active drug that reaches systemic circulation
RATIONALE:
Bioavailability is the fraction of the administered drug dose that reaches systemic circulation in its
unchanged, active form. Intravenous administration has 100% bioavailability because the drug
bypasses absorption barriers. Oral bioavailability is affected by first-pass metabolism, drug solubility,
and formulation factors. Distribution describes drug movement from blood to tissues. Metabolism
describes drug biotransformation. Excretion describes drug elimination from the body .
QUESTION 3:
A drug's half-life determines which of the following?
, NURS 6521
A. Its potency at receptor sites
B. Its duration of action and dosing interval
C. The rate of drug absorption
D. The extent of protein binding
ANSWER:
B. Its duration of action and dosing interval
RATIONALE:
Half-life (t½) is the time required for plasma concentration to decrease by 50%. It determines dosing
frequency and time to reach steady state. Drugs with shorter half-lives require more frequent
dosing, while longer half-lives allow once-daily or extended-interval dosing. Potency is determined
by receptor affinity, not half-life. Absorption rate is determined by drug formulation and route.
Protein binding influences distribution and free drug concentration .
QUESTION 4:
A drug with a short half-life typically requires which dosing strategy?
A. Less frequent dosing
B. More frequent dosing to maintain therapeutic levels
C. No maintenance dosing
D. A loading dose only
ANSWER:
B. More frequent dosing to maintain therapeutic levels
RATIONALE:
Drugs with short half-lives are eliminated rapidly, requiring frequent dosing to maintain
concentrations within the therapeutic range. Examples include morphine (t½ 2-4 hours), requiring
q4h dosing. Extended-release formulations may be used to overcome this limitation. Long half-life
drugs require less frequent dosing. All drugs requiring therapeutic effect need maintenance dosing.
Loading doses are used to rapidly achieve therapeutic levels but still require maintenance .
QUESTION 5:
The volume of distribution (Vd) indicates which of the following?
A. The extent of drug elimination
B. The extent of drug spread into body tissues
C. The rate of drug metabolism
D. The time to reach peak concentration
ANSWER:
B. The extent of drug spread into body tissues
RATIONALE:
Volume of distribution (Vd) is a theoretical volume that describes the extent to which a drug
distributes into body tissues compared to plasma. A high Vd indicates extensive tissue distribution,
