The nurse is preparing to administer the fourth dose of vancomycin IVPB to a client with infective endocarditis. Which intervention should the nurse anticipate?
- A. Starting a new IV line before the administration
- B. Administering an antiemetic PRN prior to the infusion
- C. Administering medication via an infusion pump over at least 30 minutes
- D. Obtaining a serum trough level 15-30 minutes before the administration of vancomycin
Correct Answer: D
Rationale: Vancomycin requires therapeutic drug monitoring to ensure efficacy and prevent toxicity. Obtaining a serum trough level 15-30 minutes before the fourth dose (D) is standard to guide dosing adjustments. A new IV line (A) is unnecessary unless the current line is compromised. Antiemetics (B) are not routinely needed. Infusion over 60 minutes (C) is typical to prevent red man syndrome, not 30 minutes.

Elevated hemoglobin (E) is unlikely, as anemia is more common due to chronic blood loss.
