What is the correct method to measure liquid medication?

To accurately measure liquid medication, the correct method involves reading the bottom of the meniscus. The meniscus is the curve that forms at the surface of the liquid due to surface tension. When measuring, it is important to ensure that your eye is level with the measurement line on the container. This helps avoid parallax error, which can occur if you are viewing the liquid from above or below the label line.

Reading the bottom of the meniscus provides the most accurate reading because it reflects the true volume of liquid present in the container. The other choices do not provide the precision necessary for accurate medication dosing. For instance, looking at the top of the meniscus can lead to an overestimation of the volume. Estimating visually is imprecise and can lead to significant dosing errors, and relying solely on a syringe, while it can be accurate, does not cover all scenarios in which medication might be measured. Thus, reading the bottom of the meniscus is essential for ensuring accurate and safe administration of liquid medications.
