TEST BANK
,Pharmacology Exam Revision Question Bank
This question bank is designed for high-yield NCLEX-RN
preparation, faculty review, and clinical judgment development.
The scenarios reflect actual clinical nursing challenges,
emphasizing safety, the nursing process, and the NCSBN Clinical
Judgment Measurement Model (NCJMM).
Question 1: Multiple-Choice Question (MCQ) — Foundations &
Pharmacokinetics
1. Clinical Scenario
A 54-year-old male with a history of severe hepatic cirrhosis is
admitted with a deep vein thrombosis. The healthcare provider
prescribes an oral medication that normally undergoes a high
first-pass effect.
2. Question Stem
Which pharmacokinetic principle must guide the nurse's clinical
decision-making and monitoring parameters for this patient?
• A. The medication will have a decreased bioavailability,
requiring a higher oral dose.
• B. The medication's therapeutic effect will be delayed due
to accelerated hepatic metabolism.
• C. The medication's bioavailability will be significantly
increased, elevating the risk of toxicity.
, • D. The drug will be excreted rapidly by the kidneys,
necessitating more frequent dosing intervals.
3. Answer Options
• Correct Answer: C
4. Comprehensive Rationale
The first-pass effect refers to the metabolism of an oral
medication by liver enzymes during its initial passage through
the portal circulation before reaching systemic circulation. In a
patient with severe hepatic cirrhosis, functional liver tissue is
replaced by scar tissue, significantly decreasing the liver's
metabolic capacity and shunting portal blood away from
functional hepatocytes. Consequently, drugs with a high first-
pass effect bypass this intended initial metabolism, leading to a
much higher concentration of active drug entering the systemic
circulation (increased bioavailability). This places the patient at
a high risk for profound drug toxicities unless the dosage is
adjusted downward.
5. Distractor Analysis
• Why A is Incorrect: Bioavailability will increase, not
decrease, because the compromised liver cannot
effectively metabolize the drug on its first pass. Giving a
higher dose could cause an intentional overdose.
, • Why B is Incorrect: The therapeutic effect will not be
delayed, nor is metabolism accelerated. Metabolism is
markedly slowed or impaired in cirrhosis.
• Why D is Incorrect: Hepatic impairment does not
automatically accelerate renal excretion; in fact, if the drug
accumulates due to poor liver clearance, active drug levels
remain high regardless of baseline renal function.
6. Nursing Process Integration
• Primary: Assessment. The nurse must assess liver function
panels (AST, ALT, total bilirubin, albumin) before
administration.
• Remaining Steps: Diagnosis: Risk for Injury related to drug
accumulation. Planning: Establish safe serum drug level
targets. Implementation: Administer reduced dosages as
ordered. Evaluation: Monitor for clinical signs of drug
toxicity and therapeutic drug levels.
7. Clinical Judgment Measurement Model (NCJMM)
• Competency: Analyze Cues. The nurse must connect the
patient's pathophysiological state (cirrhosis) to the drug's
metabolic pathway (first-pass effect) to anticipate potential
toxicity.
8. Cognitive Parameters
• Difficulty Level: Moderate
