& Answers with Rationales 2026–2027
Edition | 100% Correct | A+ Graded
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-30)
Question 1
Define pharmacokinetics.
A) The study of drug-receptor interactions
B) The impact of the body on drugs—how much of an
administered dose reaches its sites of action
C) The study of drug toxicity
D) The clinical use of drugs to treat disease
Correct Answer: B
Rationale: Pharmacokinetics encompasses Absorption,
Distribution, Metabolism, and Excretion (ADME)—essentially
"what the body does to the drug." This is distinct from
pharmacodynamics, which is the impact of drugs on the body.
,Question 2
Define pharmacodynamics.
A) The impact of drugs on the body—the nature and intensity of
the response
B) The movement of drugs through the body
C) The study of drug interactions
D) The process of drug elimination
Correct Answer: A
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) Administration, Digestion, Metabolism, Excretion
C) Absorption, Digestion, Metabolism, Elimination
D) Administration, Distribution, Metabolism, Excretion
Correct Answer: A
Rationale: These four processes determine drug concentration at
action sites over time, helping predict onset, peak duration, and
elimination.
,Question 4
A patient with chronic kidney disease (Stage 4) is prescribed a
medication that is primarily renally excreted. The nurse anticipates
that the patient will require:
A) A higher dose to achieve a therapeutic effect
B) A lower dose or longer dosing interval to prevent toxicity
C) The same dose as a patient with normal renal function
D) An increased frequency of administration
Correct Answer: B
Rationale: Impaired renal function significantly reduces drug
clearance, leading to drug accumulation and toxicity. Dose
reduction or extended dosing intervals are necessary to maintain
safe therapeutic levels.
Question 5
A drug with a high therapeutic index is considered:
A) More likely to cause toxicity
B) Safer because the margin between therapeutic and toxic doses
is wide
C) Requires therapeutic drug monitoring
D) Less effective
Correct Answer: B
, Rationale: The therapeutic index is the ratio between toxic and
therapeutic doses. A high therapeutic index indicates a wide
margin of safety, making toxicity less likely.
Question 6
Which organ is most responsible for drug excretion?
A) Liver
B) Kidney
C) Lungs
D) Skin
Correct Answer: B
Rationale: Kidneys excrete drugs through glomerular filtration,
tubular secretion, and reabsorption. Impaired renal function
significantly reduces drug clearance.
Question 7
What is the half-life (T1/2) of a drug?
A) Time required for the drug to be completely eliminated from
the body
B) Time required for the plasma concentration of a drug to
decrease by 50%
C) Time required for the drug to reach peak concentration
D) Time required for the drug to be absorbed
