Vital Signs include temperature, pulse, respirations, and blood pressure.

• A. Temperature and pulse only
• B. Temperature, pulse, respirations, and blood pressure
• C. Respirations only
• D. Temperature, pulse, respirations, and oxygen saturation

Answer: (B)

Vital signs are measurements that reflect the body's basic functions and help gauge a patient’s immediate health status. The classic set includes temperature, pulse, respirations, and blood pressure because together they show metabolic activity, heart function, breathing effectiveness, and circulatory status. The option that lists exactly these four matches the traditional definition, making it the best choice.

Oxygen saturation is important and often monitored, but in this item the focus is on the four classic vital signs. Including it would add an extra measure beyond what the stem specifies. Other choices are incomplete—one lists only two components, another only one—so they don’t provide the full, standard four-sign set.
