What are vital signs?

Vital signs are measurements that provide crucial information about a person's essential bodily functions. They typically include key indicators such as body temperature, heart rate, respiratory rate, and blood pressure. These indicators serve as critical indicators of an individual's overall health status and can help identify potential medical issues. Monitoring vital signs is a fundamental aspect of patient care, allowing home health aides and other caregivers to assess the physical health and needs of the individual effectively.

The other options do not accurately reflect the definition of vital signs. Emotional well-being, mood, and dietary habits are important aspects of overall health but are not classified as vital signs, which focus specifically on physiological metrics necessary for understanding a person's health condition.
