Which of the following is not one of the standard vital signs?

Cognitive function is not classified as one of the standard vital signs. Vital signs are measurements that provide critical information about a person's physiological status and include blood pressure, heart rate, respiratory rate, and, in some cases, temperature and oxygen saturation. These indicators help assess and monitor a patient's basic bodily functions.

While cognitive function is an important aspect of overall health, it is typically assessed through different methods rather than being considered a vital sign. Cognitive assessments might involve checking orientation, memory, attention, and comprehension, but these do not fall under the traditional category of vital signs used in emergency medical situations.

Understanding and recognizing standard vital signs is crucial for EMS personnel, as these measurements help guide diagnostics and treatment in pre-hospital care.
