Which of the following is NOT part of the Primary Four Vital Signs?

Explanation:
The key idea is knowing the four signs that are traditionally used for a quick initial health check: body temperature, pulse (heart rate), respiration rate, and blood pressure. Oxygen saturation isn’t part of that core quartet; it’s a valuable measurement of how well oxygen is being carried in the blood but is usually considered an additional or secondary vital sign. In practice, you still measure SpO2 to assess oxygenation, but it doesn’t belong to the primary four. So, oxygen saturation is the one that is NOT part of the Primary Four Vital Signs.
