When is it acceptable to reuse a medication-filled syringe?

The correct answer is that it is acceptable to reuse a medication-filled syringe during sequential medication doses using a single syringe. This practice is appropriate when the syringe is used to administer multiple doses of the same medication to the same patient without any interruption in the integrity of the drug and the delivery system.

In such cases, as long as the syringe has remained uncontaminated and the needle or other components have not been changed or compromised, the syringe can be reused for efficiency and to reduce waste. This practice is typically seen in controlled environments, such as during continuous infusion scenarios.

It is vital to remember that this reuse must be limited strictly to the same patient and the same medication, ensuring that there is a low risk of contamination and maintaining sterile technique throughout the process.
