Which term describes the measurements used to monitor the functioning of the body's vital organs?

• A. Validation
• B. Vision Change
• C. Vital Signs
• D. Vomitus

Answer: (C)

Vital signs are the measurements used to monitor the functioning of the body's vital organs. They include heart rate, blood pressure, respiratory rate, body temperature, and sometimes oxygen saturation. These readings give a quick snapshot of how well the circulatory and respiratory systems are working and how well the body is maintaining heat and oxygen levels. In daily CNA practice, taking vitals helps detect problems early—like fever, dehydration, infection, low blood pressure, or trouble breathing—and shows how a resident is responding to care or treatment.

The other terms don’t describe this function. Validation means confirming accuracy or legitimacy, not monitoring bodily function. Vision change relates to eyesight, not routine measurements of organ function. Vomitus is vomited material, not a measurement or assessment tool.
