Practice Question
Patient Data.
Answer Choices:
Correct Answer:
Blood urea nitrogen 17 mg/dL (6.07 mmol/L).
Rationale:
Blood urea nitrogen 17 mg/dL (within normal limits)
💎 Vancomycin is renally cleared; safe administration depends on adequate renal function to avoid drug accumulation and nephrotoxicity.
💎 A BUN of 17 mg/dL falls within the normal range (≈8–20 mg/dL), supporting appropriate clearance.
💎 The client’s creatinine 0.82 mg/dL further corroborates preserved kidney function, lowering immediate risk for toxicity.
💎 With normal renal indices, no pre‑dose renal adjustment is required (continue to monitor levels per protocol if therapy continues).
💎 Stable renal labs help prevent AKI and supratherapeutic exposure during prophylaxis.
Dosage in safe range
💎 Vancomycin 1 g IV is a commonly used adult prophylactic dose and aligns with many perioperative protocols when weight‑based calculations are not mandated.
💎 The ordered infusion 250 mL at 125 mL/hr ≈ 120 min, which is slower than the minimum 60‑minute requirement for 1 g, helping prevent infusion reactions (e.g., red man syndrome).
💎 The effective, guideline‑concordant dose and rate support antibacterial coverage while minimizing adverse effects.
💎 Dose safety always pairs with clinical monitoring (vitals, infusion site, signs of reaction).
💎 Appropriate dosing and rate together optimize efficacy and tolerability.
No known allergies
💎 Absence of documented drug allergy significantly reduces immediate risk for IgE‑mediated anaphylaxis or severe hypersensitivity to vancomycin.
💎 Screening for prior reactions to glycopeptides (e.g., vancomycin) is a critical safety step before first-dose administration.
💎 Even without allergies, the nurse should monitor closely for infusion‑related reactions (flushing, pruritus, hypotension).
💎 Clear allergy status enables timely prophylaxis without delay for alternative agents.
💎 Maintaining an updated allergy record is essential for safe antimicrobial stewardship.
Peripheral IV (PIV) in large vein
💎 Vancomycin is an irritant and can cause phlebitis if infused through small or fragile veins.
💎 A 20‑gauge PIV in the antecubital fossa qualifies as a large, high‑flow peripheral vein, lowering local infusion complications.
💎 Proper vein selection helps preserve line patency and ensures the ordered infusion rate can be safely maintained.
💎 Good vascular access reduces infiltration/extravasation risk and improves patient comfort.
💎 Optimal line choice is a core safety measure for vesicant/irritant antimicrobials.
