NUR 210 – EXAM 2: PRINCIPLES OF PHARMACOLOGY
EXAM QUESTIONS AND CORRECT ANSWERS WITH
RATIONALES GRADED A+ LATEST
1. Which factor most directly influences drug distribution?
A. Gastric pH
B. Cardiac output
C. Route of administration
D. First-pass metabolism
Correct Answer: B
Rationale: Cardiac output determines how efficiently drugs are delivered to
tissues.
2. A drug that produces less effect than a full agonist even at maximum dose is
a:
A. Antagonist
B. Partial agonist
C. Inverse agonist
D. Competitive inhibitor
Correct Answer: B
Rationale: Partial agonists have lower efficacy than full agonists.
3. Which laboratory value is most important before administering a renally
excreted drug?
A. AST
B. ALT
C. Creatinine
D. Albumin
,Correct Answer: C
Rationale: Creatinine reflects renal function and drug clearance ability.
4. Which outcome best indicates drug potency?
A. Maximum effect produced
B. Dose required to produce an effect
C. Duration of action
D. Safety margin
Correct Answer: B
Rationale: Potency reflects how much drug is needed for a response.
5. A drug that is rapidly metabolized will have:
A. Long half-life
B. Delayed onset
C. Short duration
D. Increased bioavailability
Correct Answer: C
Rationale: Rapid metabolism shortens duration of action.
6. Which patient is most at risk for accumulation of fat-soluble drugs?
A. Underweight adult
B. Older adult
C. Pediatric patient
D. Dehydrated patient
Correct Answer: B
Rationale: Increased body fat in older adults allows lipid-soluble drug storage.
,7. Which drug interaction increases the toxicity of another drug?
A. Additive
B. Synergistic
C. Antagonistic
D. Competitive
Correct Answer: B
Rationale: Synergism enhances effects, potentially causing toxicity.
8. Which route produces the slowest onset of action?
A. Intravenous
B. Intramuscular
C. Oral
D. Transdermal
Correct Answer: D
Rationale: Transdermal drugs are absorbed slowly over time.
9. Which factor most affects oral drug bioavailability?
A. Renal clearance
B. Hepatic first-pass metabolism
C. Tissue perfusion
D. Protein binding
Correct Answer: B
Rationale: First-pass metabolism reduces circulating drug levels.
10. Which term refers to the extent a drug produces its intended effect?
A. Potency
B. Efficacy
C. Affinity
D. Bioavailability
, Correct Answer: B
Rationale: Efficacy describes the maximum achievable effect.
11. Which patient condition increases free drug levels?
A. Hyperalbuminemia
B. Hypoalbuminemia
C. Increased metabolism
D. Rapid excretion
Correct Answer: B
Rationale: Low albumin reduces protein binding, increasing free drug.
12. Which type of drug reaction is dose-related and predictable?
A. Allergic reaction
B. Idiosyncratic reaction
C. Side effect
D. Anaphylaxis
Correct Answer: C
Rationale: Side effects occur at expected doses.
13. Which organ is most responsible for drug detoxification?
A. Kidneys
B. Liver
C. Lungs
D. Pancreas
Correct Answer: B
Rationale: The liver metabolizes and detoxifies drugs.
