Which action should be avoided when preparing liquid medications?

When preparing liquid medications, it is important to avoid preparing them ahead of time. This practice is discouraged because liquid medications can deteriorate over time due to factors such as exposure to light, air, or changes in temperature. These environmental factors may affect the potency and stability of the medication, leading to reduced efficacy or potential safety concerns for the patient.

Critically, measuring accurately, storing them correctly, and using appropriate utensils are all essential practices when dealing with liquid medications. Accurate measurement ensures that the correct dosage is administered, which is vital for the medication to be effective and safe. Correct storage helps to maintain the integrity of the medication up until it is needed, and using appropriate utensils prevents contamination and promotes proper dosing. Therefore, avoiding the preparation of liquid medications ahead of time is crucial to ensuring their safety and effectiveness.
