Which vital sign is NOT typically measured?

Blood glucose is typically not classified as a vital sign. Vital signs are commonly recognized measurements that provide essential information about a person's basic bodily functions and health status. These primarily include temperature, pulse, respiration rate, and blood pressure.

While blood glucose levels are important indicators of a person's metabolic state and can provide critical insights for individuals with conditions such as diabetes, they are not considered vital signs because they do not reflect the immediate physiological status of the body in the same way that the other measures do. Monitoring blood glucose levels is typically done in a clinical setting or for specific health assessments rather than as a routine vital sign check like the others.
