,NR 293 Intro to Pharmacology Mastery Quiz 2026/2027 UPDATE – Chamberlain College
1. Which pharmacokinetic process is most significantly affected by the ‘first-pass effect’ when
a drug is administered orally?
A. Metabolism
B. Distribution
C. Excretion
D. Absorption
Answer: A
Rationale: The first-pass effect refers to the extensive metabolism of a drug in the liver
after being absorbed from the gastrointestinal tract and before reaching systemic
circulation.
2. A patient with hypoalbuminemia is prescribed a highly protein-bound medication. What
clinical implication should the nurse anticipate?
A. The patient will require a higher dose to achieve therapeutic effects.
B. There will be a higher concentration of free drug, increasing the risk of toxicity.
C. The drug will be metabolized more slowly by the liver.
D. The drug will remain in the vascular space for a longer duration.
, Answer: B
Rationale: Protein-bound drugs require albumin to transport them. With low albumin
levels, fewer binding sites are available, leading to more free (active) drug in the
bloodstream, which increases the risk of toxicity.
3. A drug has a half-life of 6 hours. If a dose is administered at 08:00, how many hours will it
take for the drug to reach a steady state, assuming regular dosing?
A. 6 to 12 hours
B. 24 to 30 hours
C. 12 to 18 hours
D. 48 to 60 hours
Answer: B
Rationale: Steady state is generally reached after approximately four to five half-lives. 6
hours x 4 = 24 hours; 6 hours x 5 = 30 hours.
4. Which phase of clinical drug trials involves testing the drug on a small number of healthy
volunteers to determine its pharmacokinetics and safe dosage range?
A. Phase IV
B. Phase II
C. Phase III
D. Phase I
