Vital signs include which of the following?

• A. Temperature
• B. Pulse
• C. Respiration
• D. All of the above

Answer: (D)

Vital signs are quick checks of the body's essential functions used to gauge overall health and detect early problems. Temperature shows how hot the body is and can indicate infection, fever, or environmental exposure. Pulse measures heart rate and rhythm, reflecting cardiovascular status and how hard the heart is working. Respiration assesses breathing rate and effort, signaling how well oxygen is being taken in and carbon dioxide removed. Because each of these measurements provides important, real-time information about different body systems, the option that includes all three is the best choice. In many settings, blood pressure is also monitored as a vital sign, but recognizing that temperature, pulse, and respiration are all vital signs covers the core elements listed here. Remember to measure them accurately, note the values, and consider trends over time rather than a single reading.
