exam 300 actual questions and correct answers with
rationale latest update already graded a+ assured pass
This University of Texas at Arlington NURS 5334 exam question bank provides
300 unique multiple-choice questions covering advanced pharmacology and
clinical decision-making for nurse practitioners. Sections address
pharmacokinetics, pharmacodynamics, autonomic nervous system drugs,
cardiovascular medications, endocrine therapies, central nervous system agents,
and antimicrobial pharmacology. Each question includes four answer choices, the
correct answer, and a detailed rationale explaining the pharmacologic principle or
clinical application. Topics include CYP450 interactions, heart failure beta
blockers, diabetes therapies, anticoagulants, psychiatric medications, and antibiotic
selection. The content aligns with UT Arlington's graduate nursing curriculum and
supports preparation for exams and evidence-based prescribing.
Section 1: Pharmacokinetics and Pharmacodynamics (Questions
1–50)
Question 1
A patient with chronic kidney disease (Stage 4) is prescribed a medication that is
primarily renally excreted. The nurse anticipates that the patient will require:
A. A higher dose to achieve a therapeutic effect
B. A lower dose or longer dosing interval to prevent toxicity
C. The same dose as a patient with normal renal function
D. An increased frequency of administration
Correct Answer: B
Rationale: In renal impairment, drug clearance is reduced, leading to drug
accumulation and increased risk of toxicity. Dose reduction or extended dosing
intervals are required.
Question 2
,A drug has a half-life of 24 hours. Approximately how many hours will it take for
the drug to reach steady state?
A. 24 hours
B. 48 hours
C. 120 hours
D. 240 hours
Correct Answer: C
Rationale: Steady state is achieved after approximately 4-5 half-lives. With a half-
life of 24 hours, 4-5 half-lives equal 96-120 hours.
Question 3
A drug that is 99% protein-bound is displaced by another highly protein-bound
drug. The nurse practitioner should anticipate:
A. No change in drug effect
B. A decrease in free drug concentration
C. An increase in free drug concentration and potential toxicity
D. A decrease in drug half-life
Correct Answer: C
Rationale: Protein binding is reversible and saturable. When a highly protein-
bound drug is displaced, the free (active) fraction increases, leading to enhanced
therapeutic effect and potential toxicity.
Question 4
First-pass effect refers to:
A. Rapid renal excretion of a drug
B. Hepatic inactivation of an oral drug before it reaches systemic circulation
C. Protein binding of a drug in the bloodstream
D. Receptor downregulation after repeated dosing
Correct Answer: B
Rationale: The first-pass effect is the rapid hepatic inactivation of oral drugs after
absorption from the GI tract; the drug travels via the hepatic portal vein to the
liver, where a significant portion may be metabolized before reaching systemic
circulation.
Question 5
Which route of administration has 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
,Correct Answer: C
Rationale: Intravenous (IV) administration places the drug directly into the
systemic circulation, bypassing absorption barriers and first-pass metabolism.
Question 6
A patient is prescribed a drug that is a weak acid (pKa 4.4). In which part of the
gastrointestinal tract will absorption be most rapid?
A. Mouth (pH 7.0)
B. Stomach (pH 1.5)
C. Duodenum (pH 6.0)
D. Colon (pH 7.5)
Correct Answer: B
Rationale: Weak acids are best absorbed in acidic environments where they remain
non-ionized (lipid-soluble). In the stomach's acidic pH, the drug is predominantly
non-ionized, allowing for passive diffusion.
Question 7
A 75-year-old patient with renal impairment is prescribed a medication that is
primarily renally excreted. What is the most likely pharmacokinetic parameter that
will be altered?
A. Absorption
B. Distribution
C. Clearance
D. Metabolism
Correct Answer: C
Rationale: Clearance is the most likely parameter altered in renal impairment, as
the kidneys are responsible for excreting the drug.
Question 8
Which pharmacokinetic parameter describes the fraction of an administered dose
of a drug that reaches the systemic circulation in an unchanged form?
A. Volume of distribution
B. Bioavailability
C. Clearance
D. Half-life
Correct Answer: B
Rationale: Bioavailability is the fraction of an administered dose that reaches
systemic circulation unchanged.
Question 9
, Which of the following best distinguishes pharmacodynamics from
pharmacokinetics?
A. Pharmacodynamics is what the body does to the drug
B. Pharmacokinetics is what the drug does to the body
C. Pharmacodynamics is what the drug does to the body
D. Pharmacokinetics is the study of drug receptors
Correct Answer: C
Rationale: Pharmacodynamics is what the drug does to the body (mechanism of
action, receptor interactions), while pharmacokinetics is what the body does to the
drug (absorption, distribution, metabolism, excretion).
Question 10
The four major pharmacokinetic processes are:
A. Absorption, Digestion, Metabolism, and Excretion
B. Administration, Distribution, Metabolism, and Excretion
C. Absorption, Distribution, Metabolism, and Excretion
D. Absorption, Distribution, Metabolism, and Elimination
Correct Answer: C
Rationale: The four major pharmacokinetic processes are absorption, distribution,
metabolism, and excretion (ADME).
Question 11
A drug has a half-life of 4 hours. Approximately how long will it take for the drug
to be eliminated from the body?
A. 4 hours
B. 8 hours
C. 16-20 hours
D. 24 hours
Correct Answer: C
Rationale: A drug is considered essentially eliminated after approximately 4-5
half-lives. With a half-life of 4 hours, this is 16-20 hours.
Question 12
A patient with liver cirrhosis receives a drug that undergoes extensive first -pass
metabolism. The nurse practitioner should anticipate:
A. A decreased therapeutic effect
B. An increased therapeutic effect and potential toxicity
C. No change in drug effect
D. A decreased half-life
Correct Answer: B
