Colorado CNA Practice Exam

Which of the following is considered a vital sign?

1. Height

2. Weight

3. Body temperature

4. Blood type

The correct answer is: Height

The concept of vital signs refers to the measurements that indicate the essential functions of the body, reflecting the physiological status of a patient. Body temperature is one of these critical indicators, as it provides information about the body's metabolic state and can signal infection or other health issues. Height and weight, while important measurements in assessing a patient's overall health and growth, do not provide immediate insight into the body's vital functions as temperature does. Blood type, on the other hand, is related to the classification of blood but does not indicate immediate physiological status or function. Understanding vital signs helps healthcare providers monitor a person's health effectively and promptly identify any potential issues.
