Question 1
A 62-year-old man with newly diagnosed hypertension is prescribed lisinopril.
During the follow-up visit, he asks why his blood pressure has not reached the
target level after only three days of therapy. Which response by the nurse
practitioner is most accurate?
A. The medication reaches maximal effectiveness after one dose.
B. Most antihypertensive medications require several half-lives before steady-state
concentrations are achieved.
C. Blood pressure medications work only after two weeks regardless of the drug.
D. Increasing the dose immediately is recommended whenever the target blood
pressure is not achieved within 72 hours.
Answer: B
Rationale: Most medications require approximately 4 to 5 half-lives to reach
steady-state plasma concentrations. Therapeutic response should generally be
evaluated after adequate time has elapsed unless the patient's condition requires
urgent adjustment. Immediate dose escalation may increase adverse effects without
improving efficacy.
,Question 2
A patient reports taking an over-the-counter herbal supplement while receiving
warfarin therapy. Which action is most appropriate?
A. Continue both medications without monitoring.
B. Recommend stopping warfarin temporarily.
C. Review the specific supplement for potential drug interactions before making
recommendations.
D. Replace warfarin with aspirin.
Answer: C
Rationale: Numerous herbal supplements significantly alter warfarin metabolism
or platelet function. Medication reconciliation and assessment for interactions
should occur before recommending therapy changes.
Question 3
A 70-year-old woman with chronic kidney disease requires initiation of an
antibiotic that is primarily eliminated by the kidneys. Which prescribing principle
is most appropriate?
A. Increase the loading dose.
B. Use standard dosing regardless of renal function.
C. Adjust the dosage according to estimated renal function.
D. Double the dosing interval and increase each dose.
Answer: C
Rationale: Drugs eliminated primarily through renal excretion require dose
adjustment according to kidney function to prevent accumulation and toxicity.
,Question 4
A patient with asthma develops worsening wheezing after beginning propranolol
for migraine prophylaxis. Which pharmacologic explanation best accounts for this
reaction?
A. Alpha-1 receptor stimulation
B. Nonselective beta-receptor blockade
C. Histamine receptor activation
D. Calcium channel blockade
Answer: B
Rationale: Propranolol blocks both β1 and β2 receptors. β2 blockade causes
bronchoconstriction and may precipitate asthma exacerbations.
Question 5
A patient receiving simvastatin reports new-onset muscle pain and weakness.
Which laboratory study should be obtained first?
A. Hemoglobin A1c
B. Serum creatine kinase
C. Thyroid-stimulating hormone
D. B-type natriuretic peptide
Answer: B
Rationale: Muscle symptoms during statin therapy require evaluation for
myopathy or rhabdomyolysis. Creatine kinase is the appropriate initial laboratory
assessment.
, Question 6
A 55-year-old woman with type 2 diabetes has an A1C of 9.2% despite lifestyle
modification. Her estimated GFR is normal, and she has no contraindications to
therapy. Which medication is generally recommended as first-line pharmacologic
treatment?
A. Glyburide
B. Metformin
C. Pioglitazone
D. Regular insulin
Answer: B
Rationale: Unless contraindicated, metformin remains the preferred first-line
medication because of its efficacy, safety profile, weight neutrality, and
cardiovascular benefits.
Question 7
A patient receiving long-term prednisone abruptly stops taking the medication and
presents with weakness, hypotension, nausea, and fatigue. Which explanation best
describes this presentation?
A. Drug allergy
B. Adrenal insufficiency caused by suppression of the hypothalamic-pituitary-
adrenal axis
C. Histamine release
D. Serotonin syndrome
Answer: B
Rationale: Chronic corticosteroid therapy suppresses endogenous cortisol
production. Abrupt discontinuation may precipitate adrenal crisis.
