Clinical Nurse Specialist Pharmacology & Medication Management Flashcards

A CNS evaluates a patient who received an inadvertent double dose of insulin glargine. What is the priority nursing action?

Answer: Monitor blood glucose frequently and have IV dextrose available

Glargine's prolonged action means hypoglycemia may develop over hours; frequent glucose monitoring and IV dextrose availability are essential.

Which electrolyte abnormality must a CNS monitor for when administering loop diuretics such as furosemide?

Answer: Hypokalemia

Loop diuretics inhibit sodium-potassium-chloride cotransport in the loop of Henle, leading to potassium wasting and hypokalemia.

A CNS is reviewing a prescription for fluoroquinolone antibiotics for an older adult. Which unique counseling point should be emphasized?

Answer: Report tendon pain, which may signal rupture risk

Fluoroquinolones carry an FDA black box warning for tendinopathy and tendon rupture, particularly in patients over 60 or on corticosteroids.

When a CNS develops a formulary review for opioid stewardship, which principle is most important?

Answer: Use multimodal analgesia to minimize opioid doses

Opioid stewardship promotes multimodal analgesia combining NSAIDs, acetaminophen, and adjuvants to achieve effective pain control with minimized opioid exposure.

A CNS is developing a protocol for antibiotic de-escalation in the ICU. What is the primary benefit of this practice?

Answer: Decreases antimicrobial resistance and minimizes adverse drug effects

De-escalating from broad-spectrum to targeted antibiotics based on culture results reduces selective pressure for resistant organisms and limits adverse effects.

Which CNS action best exemplifies the spheres-of-influence model in pharmaceutical care?

Answer: Educating nursing staff on medication safety, influencing patient care across the unit

CNS practice extends through three spheres—patient/family, nurse/nursing practice, and organization/system—and educating staff creates broad practice-level impact.
