What should you monitor after administering vancomycin for potential adverse reactions?

Monitoring for signs of infusion reactions is crucial after administering vancomycin due to the potential for an adverse reaction known as "red man syndrome." This condition can occur if the medication is infused too quickly and may include symptoms such as flushing, rash, and pruritus. These reactions are often dose-dependent and can be minimized by administering the drug more slowly.

While blood pressure levels, respiratory rate, and electrolyte levels may be important for monitoring in certain clinical situations, they are not specific to vancomycin’s associated adverse effects. Blood pressure may not necessarily indicate infusion-related issues, and respiratory rate typically does not change directly due to this medication. Additionally, although vancomycin can affect kidney function and potentially lead to electrolyte imbalances, monitoring signs of infusion reactions is the most immediate and relevant consideration in post-administration care. Hence, focusing on detecting infusion-related reactions ensures timely intervention and patient safety.
