COMPLETE NCLEX TEST BANK – CHAPTERS 1-
58 QUESTIONS AND ANSWERS GUIDE
This premium item pharmacology practice question bank is
masterfully tailored to mirror the NCLEX-RN blueprint from
Linda E. McCuistion’s 11th edition. Every single high-yield,
multiple-choice question provides immediate answers
coupled with robust, clinically detailed explanations
explicitly highlighted to maximize student comprehension. It
is the ultimate digital resource for nursing students seeking
an efficient, top-tier exam preparation tool to ace their
clinical pharmacology coursework.
Question 1
A nurse is preparing to administer an oral medication that is highly
protein-bound to a patient with severe liver disease and low
serum albumin levels. What is the primary clinical concern for this
patient?
A. The medication will be metabolized too quickly.
B. The patient will experience a decreased therapeutic response.
C. There will be an increased risk of drug toxicity.
D. The drug will be excreted rapidly by the kidneys.
Answer: C
Rationale: When serum albumin levels are low, there are
fewer binding sites available for highly protein-bound drugs.
,This results in an increased amount of free, active drug
circulating in the bloodstream, significantly raising the risk
of drug toxicity.
Question 2
The nurse is monitoring a patient who has been prescribed an
agonist medication. The nurse understands that an agonist drug
functions by which mechanism?
A. Preventing receptor activation by blocking endogenous
chemicals.
B. Binding to a receptor and producing a maximum therapeutic
response.
C. Accelerating the renal excretion of toxic metabolic byproducts.
D. Neutralizing circulating stomach acids through a chemical
reaction.
Answer: B
Rationale: An agonist is a medication that binds tightly to
specific cell receptors and mimics the actions of
endogenous regulatory molecules, thereby triggering a full
therapeutic response.
Question 3
An older adult patient is prescribed a lipophilic (fat-soluble) drug.
The nurse understands that age-related changes in body
composition will have what effect on this drug's distribution?
A. The half-life of the drug will be significantly shortened.
B. The drug will remain strictly inside the intravascular space.
C. The drug will have a prolonged half-life and extended duration
of action.
,D. The drug will be completely unabsorbed in the gastrointestinal
tract.
Answer: C
Rationale: Older adults typically experience an increase in
body fat percentage and a decrease in lean muscle mass.
Fat-soluble drugs accumulate in adipose tissue, leading to a
wider distribution, a prolonged half-life, and an extended
duration of drug action.
Question 4
A patient is receiving an intravenous antibiotic with a narrow
therapeutic index. Which nursing action is most critical to ensure
safe and effective dosing?
A. Monitoring the patient's daily fluid intake and output.
B. Teaching the patient about potential long-term side effects.
C. Ensuring trough levels are drawn immediately before the next
dose.
D. Administering the medication with a high-fat meal.
Answer: C
Rationale: Drugs with a narrow therapeutic index have a slim
margin of safety between a therapeutic dose and a toxic
dose. Monitoring peak and trough serum levels—specifically
drawing a trough level right before the next scheduled
dose—is vital to prevent severe toxicities.
Question 5
During an assessment, a patient tells the nurse, "I take an over-
the-counter herbal supplement every day to help me sleep."
Under which component of the nursing process should the nurse
document this information?
, A. Nursing Assessment
B. Planning Phase
C. Interventions and Implementation
D. Evaluation of Outcomes
Answer: A
Rationale: Gathering data regarding a patient's current
medication regimen, including over-the-counter drugs,
herbal supplements, and vitamins, is a foundational element
of the subjective data collection during the Nursing
Assessment phase.
Question 6
A nurse is preparing to administer bethanechol to a patient
experiencing postoperative urinary retention. The nurse
recognizes this medication as a cholinergic agonist. Which
adverse effect should the nurse monitor for?
A. Severe tachycardia and hypertension.
B. Extreme dry mouth and blurred vision.
C. Bronchoconstriction and increased salivation.
D. Acute constipation and urinary hesitancy.
Answer: C
Rationale: Cholinergic agonists stimulate the
parasympathetic nervous system, leading to adverse effects
such as bronchoconstriction, bradycardia, excessive
salivation, diarrhea, and increased gastric secretions.
Question 7
A patient is prescribed atropine, an anticholinergic medication, to
treat symptomatic bradycardia. Which patient history finding
would represent a strict contraindication to this drug?
