What are the four main vital signs?

The four main vital signs are temperature, pulse, respirations, and blood pressure. These measurements are critical indicators of a person's essential body functions and provide crucial information about their overall health status.

Temperature indicates whether the body is maintaining a normal state or experiencing fever or hypothermia. Pulse measures the heart rate and rhythm, serving as a gauge of the heart's health and the efficiency of blood flow throughout the body. Respirations pertain to the rate at which a person breathes, which can reveal information about lung function and overall respiratory health. Blood pressure reflects the force of blood against the walls of the arteries, providing insights into cardiovascular health and the risk of heart disease.

In contrast, the other choices include measurements that, while important for assessing health, do not constitute the primary vital signs. Height, weight, age, and gender are demographic indicators rather than vital signs, and glucose levels, though critical for monitoring conditions like diabetes, are not classified as vital signs. Similarly, while oxygen saturation is important and indicates how effectively oxygen is being transported in the blood, it does not replace any of the four main vital signs. Thus, the choice highlighting temperature, pulse, respirations, and blood pressure correctly identifies the core vital signs used in clinical
