Which vital signs are CNAs responsible for measuring?

The measurement of blood pressure, pulse, respiration rate, and body temperature constitutes the critical set of vital signs that Certified Nursing Assistants (CNAs) are trained to monitor. These vital signs are essential indicators of a patient’s overall health status and can reveal important information about their physiological state, which is why CNAs play a key role in their assessment.

Blood pressure helps in identifying cardiovascular status, while pulse reflects heart rate and overall cardiac function. The respiration rate provides insight into a patient's respiratory health, and body temperature is crucial for detecting fever or hypothermia. Together, these measurements help healthcare providers make informed decisions about patient care, monitor changes over time, and identify potential health issues early.

The other options do not include the primary vital signs that CNAs are specifically tasked with measuring. While body temperature is correctly listed in the correct response, options that include weight, height, BMI, cholesterol levels, and blood sugar represent other assessments that may be relevant in a healthcare setting but are not considered core vital signs that CNAs are responsible for measuring regularly.
