Which of the following are commonly referred to as vital signs?

Vital signs are considered basic indicators of a person's essential bodily functions and health status. The commonly recognized vital signs include body temperature, pulse rate (heart rate), blood pressure, and respiratory rate. Each of these measurements provides critical information about a person's immediate health condition and can help identify medical issues that may require intervention.

Body temperature helps assess whether an individual may have an infection or other health concerns. Pulse rate reflects the heart's activity and can indicate changes in cardiovascular health. Blood pressure readings provide insight into the force of blood against artery walls, which is essential for understanding cardiovascular health. Respiratory rate can indicate the efficiency of the respiratory system and help detect issues like respiratory distress or hypoxia.

While options that include heart rate and blood glucose levels or blood oxygen levels and body temperature may seem relevant to health monitoring, they do not encompass the full standard set of vital signs used in clinical practice. The focus is primarily on the classic measures that healthcare providers routinely check to assess a patient's overall health and immediate condition. Therefore, it is this combination of body temperature, pulse rate, blood pressure, and respiratory rate that defines what are commonly referred to as vital signs.
