What describes a Mix-O-Vial?

A Mix-O-Vial is specifically designed to hold both liquid and powdered medications in a way that keeps them separate until it is necessary to combine them for administration. The vial typically features two compartments—one that contains the powdered medication and another that holds the liquid diluent. When ready for use, the process involves breaking a seal or activating a mechanism that allows the liquid to mix with the powder, creating a solution that can be administered to the patient. This design is particularly beneficial as it extends the shelf life of the powdered medication and minimizes exposure to moisture, thus maintaining the stability and efficacy of the drug until it is needed.

The other options do not accurately depict the function or design of a Mix-O-Vial, highlighting that it is not meant solely for liquid medications or for long-term storage and does not focus on IVPB solutions with preservatives.
