NURS 5334 EXAM 200 ACTUAL QUESTIONS AND
CORRECT ANSWERS WITH RATIONALE LATEST
2026 ALREADY GRADED A+
This comprehensive 200-question practice test bank is specifically designed
for the NURS 5334 Advanced Pharmacology for Nurse Practitioners course at
the University of Texas at Arlington. Covering essential topics including
pharmacokinetics, pharmacodynamics, autonomic pharmacology,
cardiovascular drugs (antihypertensives, diuretics, anticoagulants,
antiarrhythmics), diabetes management, thyroid disorders, antimicrobial
therapy, psychopharmacology, neurologic drugs, and gout medications, each
question presents realistic clinical scenarios with multiple-choice options and
includes detailed evidence-based rationales explaining mechanisms of action,
adverse effects, drug interactions, and prescribing principles. Perfect for self-
assessment, exam preparation, and reinforcing clinical decision-making.
Updated for 2025-2026 academic standards, this essential resource helps
nurse practitioner students master advanced pharmacology concepts and
achieve success on the NURS 5334 examination.
Question 1
A patient with chronic kidney disease (Stage 4) is prescribed a medication that is
primarily renally excreted. The nurse practitioner 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
Answer: B
Rationale: In patients with renal impairment, renally excreted medications
accumulate, leading to potential toxicity. Dose reduction or extended dosing
intervals are necessary to maintain therapeutic levels without causing adverse
effects .
Question 2
,What is the most accurate device for measuring a 2.5 mL dose for a child?
A) Household teaspoon
B) Oral syringe
C) Medicine cup
D) Dropper
Answer: B
Rationale: An oral syringe is the most accurate device for measuring small liquid
doses in children. Household teaspoons vary in size and are inaccurate for precise
medication dosing .
Question 3
In the elderly, the proper index of renal function is:
A) Serum creatinine alone
B) Creatinine clearance or GFR
C) Blood urea nitrogen
D) Urine output
Answer: B
Rationale: Serum creatinine alone is an unreliable indicator of renal function in the
elderly due to decreased muscle mass. Creatinine clearance or estimated GFR
provides a more accurate assessment of renal function for drug dosing .
Question 4
Which factor contributes to the increase in adverse drug reactions in the geriatric
population?
A) Polypharmacy
B) Multiple pathologies
C) Greater use of drugs with a low therapeutic index
D) All of the above
Answer: D
Rationale: Elderly patients are at increased risk for adverse drug reactions due to
polypharmacy, multiple comorbidities, age-related pharmacokinetic changes, and
the use of medications with narrow therapeutic windows .
Question 5
A patient is prescribed a medication that is primarily renally excreted. The nurse
practitioner knows that which pharmacokinetic parameter will be most affected?
A) Absorption
B) Distribution
C) Metabolism
D) Elimination
,Answer: D
Rationale: Renal excretion is a key component of drug elimination. When renal
function is impaired, drugs that are primarily renally excreted will have prolonged
elimination half-lives and require dose adjustment .
Question 6
What is the difference between pharmacokinetics and pharmacodynamics?
A) Pharmacokinetics is what the drug does to the body; pharmacodynamics is what
the body does to the drug
B) Pharmacokinetics is what the body does to the drug; pharmacodynamics is what
the drug does to the body
C) Pharmacokinetics and pharmacodynamics are the same
D) Pharmacokinetics refers to drug interactions
Answer: B
Rationale: Pharmacokinetics describes the movement of drugs through the body
(absorption, distribution, metabolism, excretion). Pharmacodynamics describes the
effects of the drug on the body, including receptor binding and clinical response .
Question 7
Acetylcholine binds to which types of receptors?
A) Alpha and beta
B) Nicotinic and muscarinic
C) Dopamine and serotonin
D) GABA and glutamate
Answer: B
Rationale: Acetylcholine is the neurotransmitter for both nicotinic and muscarinic
receptors. Nicotinic receptors are found at the neuromuscular junction and in
autonomic ganglia; muscarinic receptors are found on target organs of the
parasympathetic nervous system .
Question 8
Norepinephrine binds to which types of receptors?
A) Nicotinic and muscarinic
B) Alpha and beta
C) Dopamine and serotonin
D) GABA and glutamate
Answer: B
Rationale: Norepinephrine is the primary neurotransmitter for the sympathetic
nervous system and binds to both alpha and beta adrenergic receptors. Alpha
, receptors mediate vasoconstriction; beta receptors mediate cardiac stimulation and
bronchodilation .
Question 9
Atropine is considered the antidote to which type of toxicity?
A) Cholinergic toxicity
B) Adrenergic toxicity
C) Serotonergic toxicity
D) GABAergic toxicity
Answer: A
Rationale: Atropine is a muscarinic antagonist used as the antidote for cholinergic
toxicity (e.g., organophosphate poisoning). It blocks the effects of excess
acetylcholine at muscarinic receptors, reversing bradycardia, bronchoconstriction,
and excessive secretions .
Question 10
Which drug class is most commonly associated with a dry, persistent cough as a
side effect?
A) Beta-blockers
B) ACE inhibitors
C) Calcium channel blockers
D) Thiazide diuretics
Answer: B
Rationale: ACE inhibitors (e.g., lisinopril, enalapril) commonly cause a dry,
persistent cough due to accumulation of bradykinin in the lungs. This is a class
effect and occurs in approximately 5-20% of patients. ARBs do not typically cause
this cough .
Question 11
What is the mechanism of action of ACE inhibitors?
A) Block beta-1 receptors in the heart
B) Block the conversion of angiotensin I to angiotensin II
C) Block calcium channels in vascular smooth muscle
D) Inhibit the renin enzyme directly
Answer: B
Rationale: ACE inhibitors (ending in "-pril") block the angiotensin-converting
enzyme, preventing conversion of inactive angiotensin I to active angiotensin II.
This leads to vasodilation and decreased aldosterone secretion .
