Which of the following is NOT a vital sign monitored by CCAs?

Vital signs are essential indicators of a person's health and include measurements that provide information about the body's basic functions. The monitoring of blood pressure, pulse, and temperature is fundamental practice for Continuing Care Assistants (CCAs) as these signs help assess the overall physiological state of a patient.

Blood pressure gives insight into the force of blood against artery walls and can indicate various conditions, including hypertension or hypotension. The pulse reflects heart rate and rhythm, which can be indicative of cardiovascular health. Temperature monitoring is crucial for detecting fever or hypothermia, which can signal infection or other health issues.

Vision, however, is not classified as a vital sign. While visual assessments can be important for understanding certain health aspects, such as detecting vision impairments or eye health, they do not provide the same fundamental physiological insights as blood pressure, pulse, and temperature do. Therefore, it is not part of the core set of vital signs monitored by CCAs in their daily care practice.
