What is a graduate used for?

A graduate, also known as a graduated cylinder or measuring cup, is specifically designed for measuring the volume of liquids. It is marked with incremental lines, allowing for precise measurement of fluid quantities. This tool is commonly used in various healthcare settings, ensuring that precise volumes of medications or IV fluids can be administered safely and accurately.

The other choices do not accurately describe the function of a graduate. For instance, temperature is measured with a thermometer, weight is measured with a scale, and heart rate is assessed using a stethoscope or heart rate monitor. Each of these tools serves a different purpose specific to their measurements, highlighting the specialized role of the graduate in measuring liquid volumes.
