UTA NURS 5334 ADVANCED PHARMACOLOGY QUIZ 2
Study Guide with Clinical Pearls
250 Questions with Rationales
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-50)
Question 1
A nurse practitioner is reviewing the concept of pharmacokinetics with a
student. Which statement best defines pharmacokinetics in the context of
advanced pharmacology?
A) The study of the biochemical and physiologic effects of drugs on the body
B) The study of how the body processes drugs through absorption, distribution,
metabolism, and excretion
C) The study of drug interactions at receptor sites
D) The study of the toxic effects of medications
Rationale: The correct answer is B. Pharmacokinetics is defined as "what the
body does to the drug," encompassing the processes of drug absorption,
distribution, metabolism, and excretion (ADME) . Pharmacodynamics is "what
the drug does to the body" .
Question 2
Pharmacodynamics is best defined as:
, Page 2 of 91
A) The impact of the body on drugs
B) The study of drug absorption and distribution
C) The nature and intensity of the response to a drug
D) The process of drug excretion
Rationale: The correct answer is C. Pharmacodynamics refers to the
biochemical and physiologic effects of the drug and its mechanism of action—
what the drug does to the body . This includes the nature and intensity of the
response .
Question 3
A patient has a creatinine clearance of 25 mL/min. Which class of
medications would require the most significant dose adjustment?
A) Drugs metabolized by the liver
B) Drugs excreted renally
C) Drugs with high protein binding
D) Drugs with a large volume of distribution
Rationale: The correct answer is B. Creatinine clearance reflects renal function.
Drugs that are excreted renally will accumulate in patients with reduced
creatinine clearance, requiring dose reduction .
Question 4
Which of the following factors increases the volume of distribution (Vd) of
a drug?
A) High plasma protein binding
B) Low lipid solubility
C) High tissue binding
D) Low tissue binding
, Page 3 of 91
Rationale: The correct answer is C. High tissue binding increases the volume
of distribution . Drugs that are highly lipophilic and extensively tissue-bound
distribute widely throughout the body.
Question 5
The therapeutic index of a drug is defined as:
A) The ratio of the therapeutic dose to the toxic dose
B) The ratio of the toxic dose (TD50) to the therapeutic dose (ED50)
C) The time required for a drug to reach steady-state
D) The fraction of drug reaching systemic circulation
Rationale: The correct answer is B. The therapeutic index is the ratio of the
toxic dose (TD50) to the therapeutic dose (ED50) . A larger therapeutic index
indicates a safer drug with a wider margin between therapeutic and toxic
effects.
Question 6
Which of the following describes the "ion trapping" phenomenon in
pharmacology?
A) Drugs accumulate in compartments where they are ionized
B) Drugs are trapped in the liver during first-pass metabolism
C) Drugs bind irreversibly to plasma proteins
D) Drugs are trapped in the kidneys during filtration
Rationale: The correct answer is A. Ion trapping occurs when a drug
accumulates in a compartment where it is ionized and cannot cross lipid
membranes . Weak bases accumulate in acidic compartments, and weak acids
accumulate in alkaline compartments.
Question 7
What is the effect of a CYP450 inhibitor on a drug that is a CYP substrate?
, Page 4 of 91
A) Increased drug metabolism and decreased effect
B) Decreased drug metabolism and increased effect/toxicity
C) No effect on drug metabolism
D) Increased drug excretion
Rationale: The correct answer is B. CYP450 inhibitors decrease the
metabolism of substrate drugs, leading to increased drug concentrations and
potential toxicity . Dose reductions may be necessary when inhibitors are added
to therapy.
Question 8
What is the effect of a CYP450 inducer on a drug that is a CYP substrate?
A) Increased drug metabolism and decreased effect
B) Decreased drug metabolism and increased effect/toxicity
C) No effect on drug metabolism
D) Decreased drug excretion
Rationale: The correct answer is A. CYP450 inducers increase the metabolism
of substrate drugs, leading to decreased drug concentrations and reduced
therapeutic effect . Dose increases may be necessary.
Question 9
Which of the following is a potent CYP3A4 inhibitor?
A) Rifampin
B) Grapefruit juice
C) Phenytoin
D) Carbamazepine
Rationale: The correct answer is B. Grapefruit juice is a potent CYP3A4
inhibitor . Inhibitors decrease metabolism of substrates, leading to increased
drug concentrations and potential toxicity. Rifampin, phenytoin, and
carbamazepine are CYP3A4 inducers .
