What is the best practice for measuring a liquid medication for a resident?

Using a plastic medication cup with graduated measurements is the best practice for measuring liquid medication for a resident. These cups are specifically designed for this purpose, ensuring both accuracy and ease of use. The graduated markings allow caregivers to measure the precise amount of medication needed, which is vital for safety and efficacy in medication administration. Accurate measurement helps avoid dosage errors, which can have serious consequences for the health of the resident.

Other methods, such as using a metal spoon or a drinking glass, can lead to variations in measurement due to differences in size or shape, making it difficult to standardize dosages. Additionally, a syringe without measurement marks does not provide a clear way to measure out the necessary quantity, potentially resulting in underdosing or overdosing. Thus, a plastic medication cup with graduated measurements stands out as the most reliable and accurate option for measuring liquid medication in an assisted living setting.
