NURS 5334 Advanced Pharmacology Comprehensive Final Exam – 250 Practice Questions with
Rationales
Exam Advanced pharmacokinetics, pharmacodynamics, drug therapy processes, major therapeutic dru
Focus classes, special populations
UNIT 1: PHARMACOKINETICS & PHARMACODYNAMICS
Question 1
Define pharmacokinetics.
A) The impact of drugs on the body – the nature and intensity of the response
B) The impact of the body on drugs – how much of an administered dose reaches its sites of
action
C) The study of drug interactions with receptors
D) The process of drug excretion from the body
Answer: B
, Page 2 of 96
Rationale: Pharmacokinetics encompasses Absorption, Distribution, Metabolism, and Excretion
(ADME). It answers "What does the body do to the drug?" Pharmacodynamics, in contrast, is
the impact of drugs on the body – what the drug does to the body.
Question 2
Define pharmacodynamics.
A) The impact of the body on drugs – how much of an administered dose reaches its sites of
action
B) The impact of drugs on the body – the nature and intensity of the response
C) The study of drug metabolism in the liver
D) The process of drug absorption from the GI tract
Answer: B
Rationale: Pharmacodynamics includes receptor binding, post-receptor effects, and clinical
response. It answers "What does the drug do to the body?"
Question 3
What are the four major pharmacokinetic processes?
A) Absorption, Distribution, Metabolism, Excretion (ADME)
B) Absorption, Digestion, Metabolism, Elimination
, Page 3 of 96
C) Administration, Distribution, Metabolism, Excretion
D) Absorption, Distribution, Metabolism, Elimination
Answer: A
Rationale: These four processes determine drug concentration at action sites over time, helping
predict onset, peak duration, and elimination.
Question 4
A drug with a high therapeutic index is considered:
A) More likely to cause toxicity
B) Safer with a wider margin between effective and toxic doses
C) Less effective at lower doses
D) More likely to require therapeutic drug monitoring
Answer: B
Rationale: A high therapeutic index (TI = TD50/ED50) indicates a wide margin of safety between
effective and toxic doses. Drugs with a narrow TI (warfarin, digoxin, lithium, phenytoin) require
therapeutic drug monitoring to avoid toxicity.
Question 5
Which organ is most responsible for drug excretion?
, Page 4 of 96
A) Liver
B) Kidney
C) Lungs
D) Skin
Answer: B
Rationale: Kidneys excrete drugs through glomerular filtration, tubular secretion, and
reabsorption. Impaired renal function significantly reduces drug clearance and requires dose
adjustment.
Question 6
What is the volume of distribution (Vd)?
A) The volume of blood cleared of drug per unit time
B) The apparent volume into which a drug distributes (dose/plasma concentration)
C) Time for drug concentration to decrease by 50%
D) Fraction of drug reaching systemic circulation
Answer: B
Rationale: Vd = (amount of drug in body) / (plasma drug concentration). High lipid solubility or
tissue binding = large Vd. Drugs confined to plasma have small Vd (3-5 L). A high Vd indicates
extensive tissue binding and uptake.
