NR 567 FINAL EXAM – ADVANCED PHARMACOLOGY
FOR THE AGACNP 350 PRACTICE QUESTIONS WITH
ANSWERS & RATIONALES CHAMBERLAIN
UNIVERSITY (2026–2027)
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1–30)
1. Which parameter primarily determines a drug's volume of distribution
(Vd)?
A) Renal clearance
B) Protein binding
C) Lipid solubility and tissue binding
D) Halflife
Answer: C) Lipid solubility and tissue binding
Rationale: Vd reflects how extensively a drug distributes into tissues;
lipophilic drugs with tissue binding have larger Vd.
2. A patient with severe hepatic failure will most likely have which change in
drug pharmacokinetics?
A) Increased renal excretion
B) Decreased oral absorption
C) Reduced metabolism and prolonged halflife of hepatically cleared drugs
D) Increased protein binding
,Answer: C) Reduced metabolism and prolonged halflife of hepatically cleared
drugs
Rationale: Hepatic failure reduces metabolism of drugs cleared by the liver,
increasing halflife and drug exposure.
3. Mrs. Thompson is a 72yearold woman with CHF and CKD (eGFR = 28
mL/min). She was started on a renally eliminated antibiotic. After two doses,
she complains of nausea and dizziness. What is the most likely
pharmacokinetic explanation?
A) Reduced renal elimination leading to increased plasma drug concentration
B) Increased volume of distribution due to fluid overload
C) Enhanced hepatic metabolism producing toxic metabolites
D) Increased firstpass effect decreasing drug bioavailability
Answer: A) Reduced renal elimination leading to increased plasma drug
concentration
Rationale: In patients with impaired renal function, drugs primarily renally
excreted accumulate, increasing plasma concentrations and risk of toxicity.
4. A 65yearold man with alcoholic cirrhosis presents with confusion and
tremor after starting a benzodiazepine. Which pharmacokinetic change most
accounts for his increased drug effect?
A) Decreased plasma protein binding resulting in increased free drug
B) Enhanced renal clearance increasing active metabolite removal
C) Reduced absorption from gastrointestinal edema
D) Increased firstpass metabolism through hepatic hyperperfusion
,Answer: A) Decreased plasma protein binding resulting in increased free drug
Rationale: In cirrhosis, reduced plasma protein (especially albumin) increases
the free fraction of highly proteinbound drugs, enhancing effect.
5. A drug follows a twocompartment pharmacokinetic model with a rapid
distribution phase (alpha halflife 0.5 hours). Which statement best describes
this drug?
A) It achieves steady state within 30 minutes
B) It distributes rapidly from central to peripheral compartments
C) It has zeroorder elimination kinetics
D) It is completely proteinbound
Answer: B) It distributes rapidly from central to peripheral compartments
Rationale: A short alpha halflife indicates rapid distribution from the central
compartment (blood) to peripheral tissues.
6. Which of the following best describes the halflife (t½) of a drug?
A) The time required for the drug to reach maximum concentration
B) The time required for the plasma concentration to decrease by 50%
C) The time required for complete elimination of the drug
D) The time required for the drug to be absorbed
Answer: B) The time required for the plasma concentration to decrease by
50%
7. A drug has a halflife of 68 hours. How long will it take to reach steady state?
A) 68 hours
, B) 136 hours
C) Approximately 14 days
D) 340 hours
Answer: C) Approximately 14 days
Rationale: Steady state is achieved after approximately 45 halflives. 68 hours
× 5 = 340 hours ≈ 14 days.
8. Which parameter primarily determines a drug's renal clearance?
A) Lipid solubility
B) Protein binding
C) Glomerular filtration rate and tubular secretion
D) Volume of distribution
Answer: C) Glomerular filtration rate and tubular secretion
9. A drug with high firstpass metabolism would require which of the
following?
A) Higher oral dose
B) Lower oral dose
C) Intravenous administration to avoid firstpass effect
D) Topical administration
Answer: C) Intravenous administration to avoid firstpass effect
10. Which of the following drugs undergoes extensive firstpass metabolism?
