What technique is advised when mixing a powdered medication?

1. Mix it thoroughly using a metal spoon.

2. Stir gently without creating bubbles.

3. Shake vigorously to ensure proper dissolution.

4. Add the diluent slowly to avoid clumping.

The correct answer is: Shake vigorously to ensure proper dissolution.

When mixing a powdered medication, shaking vigorously is not generally advised because it can lead to the formation of bubbles or froth, which might negatively affect the accurate dosing of the medication or cause the solution to be difficult to use. The best approach is to add the diluent slowly. This technique allows the powder to dissolve evenly and minimizes the risk of clumping, ensuring a more uniform solution. By introducing the diluent gradually, the powdered medication can properly absorb the liquid, leading to a smoother mixture. This method also helps maintain the integrity of the medication, as excessive agitation from vigorous shaking can degrade certain formulations or affect their efficacy. A few of the other approaches mentioned lack effectiveness as well: using a metal spoon for mixing is not recommended as it could scratch or interact with some medications, stirring gently without creating bubbles may not be adequate to ensure complete dissolution, and vigorous shaking typically results in unwanted bubbles. Therefore, adding the diluent slowly is crucial for creating a homogenous and effective medication mixture.
