Which nursing intervention is key when administering vancomycin?

• A. Infuse quickly to improve efficacy
• B. Infuse slowly over at least an hour
• C. Administer with food to increase absorption
• D. Monitor glucose levels

Answer: (B)

Infusing vancomycin slowly over at least an hour is critical because rapid infusion can lead to serious adverse reactions, such as "Red Man Syndrome," which is characterized by hypotension and a red rash on the upper body or face. This syndrome occurs when the drug is administered too quickly and is not related to an allergic reaction. The recommendation to infuse the medication over a longer period allows for a more controlled delivery, reducing the risk of these complications.

Additionally, the pharmacokinetics of vancomycin suggest that a slow infusion helps maintain steady drug levels, optimizing the therapeutic effect while minimizing potential side effects. This careful administration reflects a comprehensive understanding of intravenous medication protocols, which prioritize patient safety and effective treatment outcomes.
