,Q1. A patient with a history of chronic alcohol use is prescribed a hepatically metabolized drug that
undergoes extensive first-pass metabolism. The nurse anticipates that the prescriber may need to adjust the
dose. Which pharmacokinetic principle best explains why a higher-than-usual oral dose might be required?
A. Reduced hepatic enzyme activity due to alcohol-induced cirrhosis increases drug bioavailability.
B. Induction of cytochrome P450 enzymes by chronic alcohol accelerates drug metabolism, reducing systemic
exposure.
C. Decreased gastric pH from alcohol consumption enhances drug absorption, leading to higher peak
concentrations.
D. Increased plasma protein binding in alcoholics reduces the free fraction of the drug available for
distribution.
Correct Answer: B. Induction of cytochrome P450 enzymes by chronic alcohol accelerates drug metabolism,
reducing systemic exposure.
Rationale: Chronic alcohol consumption induces CYP2E1 and other P450 enzymes, accelerating metabolism of
many drugs and reducing their bioavailability after oral administration. This often necessitates higher oral doses.
Option A is incorrect because cirrhosis actually reduces enzyme activity, but the question specifies chronic use
without cirrhosis. Option C is not a consistent effect of alcohol. Option D is incorrect because alcohol may
decrease protein binding, not increase it.
Why Wrong:
A - Cirrhosis would decrease metabolism, but the question implies chronic use without liver failure; induction
is the primary effect.
C - Alcohol can increase gastric acid secretion, but this does not reliably enhance absorption of most drugs.
D - Chronic alcohol use tends to decrease albumin and binding capacity, reducing protein binding.

Q2. A drug that acts as a partial agonist at a receptor would produce which of the following effects when
administered alone and then administered with a full agonist?
A. When given alone, it produces maximal effect; when combined with a full agonist, it potentiates the effect.
B. When given alone, it produces submaximal effect; when combined with a full agonist, it reduces the effect
of the full agonist.
C. When given alone, it has no effect; when combined with a full agonist, it has no effect on the full agonist.
D. When given alone, it produces an effect inverse to the full agonist; when combined, it reverses the full
agonist effect.
Correct Answer: B. When given alone, it produces submaximal effect; when combined with a full agonist, it
reduces the effect of the full agonist.
Rationale: A partial agonist has lower intrinsic efficacy than a full agonist, so alone it produces a submaximal
response. When combined with a full agonist, it competes for the same receptor and reduces the response to the full
agonist (net effect is between the two). Option A describes a full agonist. Option C is incorrect because a partial
agonist does have some effect. Option D describes an inverse agonist.
Why Wrong:
A - This describes a full agonist, not a partial agonist.
C - Partial agonists have intrinsic activity, so they do produce an effect when given alone.
D - Inverse agonists produce opposite effects; partial agonists do not reverse full agonist effects.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 2 (Receptor Theory), pp. 30-33.
Q3. A patient is receiving an intravenous infusion of a drug at a rate of 5 mg/min. The drug has a half-life of
4 hours and follows first-order elimination. Approximately how long will it take to reach steady-state
concentration?
A. 8 hours
B. 12 hours
Page 3
, C. 16 hours
D. 20 hours
Correct Answer: D. 20 hours
Rationale: Steady state is achieved after approximately 4-5 half-lives. With a half-life of 4 hours, 5 half-lives = 20 hours.
Option A (8 hours) is only 2 half-lives, reaching about 75% of steady state. Options B and C are insufficient for 95%+ steady
state.
Why Wrong:
A - 8 hours is only 2 half-lives, which achieves about 75% of steady state, not full steady state.
B - 12 hours is 3 half-lives (87.5%), still not full steady state.
C - 16 hours is 4 half-lives (93.75%), but 5 half-lives (20 hours) is the standard for complete steady state.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4 (Pharmacokinetics), pp. 55-57.
Q4. Based on the exhibits, which of the following is the most appropriate nursing action?
A. Hold metformin, avoid IV contrast, start insulin, hold lisinopril, order low-sodium diet
B. Continue metformin, administer IV contrast, start insulin, continue lisinopril, order low-sodium diet
C. Hold metformin, avoid IV contrast, start insulin, continue lisinopril, order low-sodium diet
D. Hold metformin, avoid IV contrast, hold insulin, hold lisinopril, order low-sodium diet
Correct Answer: A. Hold metformin, avoid IV contrast, start insulin, hold lisinopril, order low-sodium diet
Rationale: Metformin should be held due to elevated creatinine/eGFR (risk of lactic acidosis). IV contrast is
contraindicated because it can worsen renal function. Insulin sliding scale is anticipated for hyperglycemia.
Lisinopril is contraindicated with elevated creatinine and risk of hyperkalemia (potassium is 4.5, but with declining
renal function, ACE inhibitors can worsen renal function and cause hyperkalemia). Low-sodium diet is
nonessential for the acute pneumonia but may be beneficial long-term. Thus option A matches these decisions.
Why Wrong:
B - Continuing metformin and administering IV contrast are unsafe given renal impairment.
C - Continuing lisinopril is not safe with elevated creatinine and risk of further decline.
D - Holding insulin is inappropriate for hyperglycemia (blood glucose 180).
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 46 (Antidiabetic Drugs), pp.
720-725; Ch. 53 (ACE Inhibitors), pp. 830-835.
Q5. A patient is receiving a beta-1 selective antagonist (e.g., atenolol) for hypertension. The nurse is also
monitoring for potential adverse effects. Which of the following findings would most likely indicate an
unintended beta-2 blockade effect?
A. Heart rate of 52 beats per minute
B. Wheezing and shortness of breath
C. Orthostatic hypotension
D. Peripheral vasodilation and flushing
Correct Answer: B. Wheezing and shortness of breath
Rationale: Beta-1 selective antagonists primarily block beta-1 receptors in the heart, but at higher doses they can
also block beta-2 receptors in the lungs, leading to bronchoconstriction (wheezing, SOB). Option A is a desired
effect of beta-1 blockade (reduced heart rate). Option C is not typical of beta blockers; they may cause hypotension
but not primarily orthostatic. Option D is not an effect of beta blockers; they cause vasoconstriction due to
unopposed alpha activity.
Why Wrong:
A - Bradycardia is a therapeutic effect of beta-1 blockade, not an unintended beta-2 effect.
C - Orthostatic hypotension is more common with alpha blockers or vasodilators, not beta blockers.
D - Beta blockers cause vasoconstriction, not vasodilation; flushing is not expected.
