This comprehensive document contains questions and verified answers for the NSG
5240 Advanced Pharmacology Midterm Exam at South College. Questions cover
pharmacodynamics, pharmacokinetics, autonomic pharmacology, cardiovascular
drugs, endocrine agents, antimicrobials, CNS medications, pain management, and
special populations . Each answer includes the correct option in bold with a detailed
rationale.
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1–30)
1. A drug with a high volume of distribution (Vd) would most likely:
A) Remain primarily in the vascular compartment
B) Have extensive tissue binding and distribution
C) Be eliminated rapidly by the kidneys
D) Require no loading dose
Answer: B
,A high volume of distribution indicates that the drug has extensively distributed into tissues
beyond the vascular compartment. Drugs with high Vd are often lipophilic and highly
protein-bound, leading to extensive tissue sequestration and longer half-lives .
2. The rate of drug elimination is directly proportional to plasma concentration in
which type of kinetics?
A) Zero-order kinetics
B) First-order kinetics
C) Michaelis-Menten kinetics
D) Nonlinear kinetics
Answer: B
In first-order kinetics, a constant fraction of the drug is eliminated per unit time, and the rate
of elimination is directly proportional to plasma concentration. This is the most common
elimination pattern for most drugs at therapeutic concentrations .
3. Which cytochrome P450 enzyme is responsible for the metabolism of the largest
number of drugs?
A) CYP1A2
B) CYP2C9
C) CYP2D6
D) CYP3A4
Answer: D
,CYP3A4 is responsible for metabolizing approximately 50% of all drugs on the market. It is
the most abundant CYP450 enzyme in the liver and intestines. Clinically significant drug
interactions frequently involve CYP3A4 inhibition or induction .
4. A patient with chronic kidney disease (CKD) has a decreased glomerular filtration
rate (GFR). Which pharmacokinetic process is most directly affected, potentially
leading to drug accumulation and toxicity?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Answer: D
Excretion via the kidneys is reduced when GFR declines, requiring dosage adjustment for
renally cleared drugs. Drugs such as digoxin, aminoglycosides, and vancomycin require
dose adjustment in CKD .
5. An 80-year-old patient with decreased serum albumin is prescribed warfarin. Which
pharmacokinetic parameter is most likely altered, increasing the risk of adverse
effects?
A) Bioavailability
B) Volume of distribution for protein-bound drugs
C) Hepatic metabolism
D) Renal tubular secretion
Answer: B
, Hypoalbuminemia increases the free (unbound) fraction of highly protein-bound drugs like
warfarin, potentially enhancing effect and toxicity. Monitoring INR is essential .
6. The half-life (t½) of a drug is best described as:
A) The time required for the drug to reach steady state
B) The time required for the drug to be completely eliminated from the body
C) The time required for the plasma concentration to decrease by 50%
D) The time required to achieve therapeutic effect
Answer: C
Half-life is defined as the time required for the plasma concentration of a drug to be reduced
by 50%. It determines dosing frequency and time to reach steady state (approximately 4-5
half-lives) .
7. A drug that acts as a partial agonist would demonstrate:
A) Maximal effect equal to a full agonist
B) Submaximal effect even at full receptor occupancy
C) No intrinsic activity
D) Antagonism of all receptor effects
Answer: B
Partial agonists have intrinsic activity between 0 and 1. Even when all receptors are
occupied, they produce less than the maximal response achievable by a full agonist.
Buprenorphine is a classic example used in opioid use disorder .
