,NUR 2474 Final Exam Pharmacology for Professional Nursing
Questions And Answers 2026/2027 Rasmussen
Q1.
Which statement best describes pharmacokinetics?
A) What the drug does to the body
B) What the body does to the drug
C) How a drug is named
D) How a medication is prescribed
Correct Answer: B) What the body does to the drug
Rationale: Pharmacokinetics describes absorption, distribution, metabolism,
and excretion of medications.
Q2.
Which pharmacokinetic process occurs when a medication moves
from the site of administration into systemic circulation?
A) Distribution
B) Metabolism
C) Absorption
D) Excretion
Correct Answer: C) Absorption
Rationale: Absorption is the movement of a drug from its administration
site into the bloodstream.
Q3.
Which organ is primarily responsible for metabolism of many
medications?
A) Heart
B) Liver
C) Pancreas
D) Spleen
Correct Answer: B) Liver
Rationale: The liver contains enzymes that metabolize many medications,
often making them easier to eliminate.
Q4.
Which patient factor can increase the risk of drug accumulation?
A) Increased renal clearance
B) Renal impairment
, C) Increased appetite
D) Increased tissue perfusion
Correct Answer: B) Renal impairment
Rationale: Impaired kidney function can decrease drug elimination and
cause medications or metabolites to accumulate.
Q5.
What is the half-life of a medication?
A) Time until the medication begins working
B) Time required for 50% of the drug to be eliminated
C) Time until all adverse effects disappear
D) Time needed for absorption to begin
Correct Answer: B) Time required for 50% of the drug to be eliminated
Rationale: Half-life is the time needed for the amount or plasma
concentration of a drug to decrease by 50%.
Q6.
Which statement correctly distinguishes an agonist from an
antagonist?
A) An agonist blocks a receptor, whereas an antagonist activates it
B) An agonist activates a receptor, whereas an antagonist blocks or reduces
receptor activity
C) Both drugs always activate receptors
D) Both drugs permanently destroy receptors
Correct Answer: B) An agonist activates a receptor, whereas an antagonist
blocks or reduces receptor activity
Rationale: Agonists produce receptor-mediated responses, while
antagonists interfere with receptor activation.
Q7.
Which finding represents a therapeutic effect?
A) Desired reduction in blood pressure after an antihypertensive
B) Severe anaphylaxis
C) Liver toxicity
D) Respiratory depression
Correct Answer: A) Desired reduction in blood pressure after an
antihypertensive
Rationale: A therapeutic effect is the intended beneficial response to a
medication.
