Which of the following is typically one of the four vital signs measured by a CNA?

Temperature is one of the four vital signs that are routinely measured by a CNA. The four vital signs include temperature, pulse, respiration rate, and blood pressure. Monitoring these signs is essential for assessing a patient's overall health and identifying any potential medical issues.

Temperature is a key indicator of the body’s ability to maintain homeostasis, and any significant deviation from the normal range can indicate an infection or illness. This measurement is typically taken using thermometers, and it is important for CNAs to be proficient in this task to deliver effective care.

The other options, although important in medical assessments, are not classified as the four primary vital signs. Oxygen saturation is a valuable measurement, particularly in respiratory care, but it is not one of the core vital signs. Blood sugar levels are significant for managing conditions like diabetes but are not classified as a vital sign. Electrocardiogram readings provide crucial information regarding heart health but are more specialized and typically outside the scope of routine tasks for CNAs.
