What process involves the addition of water to a powdered medication to prepare it for use?

The process of reconstitution specifically refers to the addition of water (or another solvent) to a powdered medication to convert it into a usable liquid form. This is commonly required for certain medications that are provided in a powdered form to ensure stability and prolong shelf life. When a patient or healthcare provider needs to administer the medication, they will add the specified amount of water to the powder, making it easier to measure and administer accurately.

In contrast, dilution involves adding a solvent to an already liquid solution to decrease its concentration, while infusion refers to the process of slowly administering a liquid, such as in IV therapy. Mixing refers to combining two or more substances without necessarily focusing on the addition of a solvent to a powder. These differences highlight why reconstitution is the correct term for the process described in the question.
