Vital signs are the basic measurements that give your care team a snapshot of how your body is functioning. Understanding what blood pressure, heart rate, respiratory rate, temperature, and oxygen saturation numbers mean — and why they matter — makes it easier to ask informed questions at appointments and to recognize when something needs attention. This quiz covers the concepts behind eight essential vital-sign facts. Read each explanation after answering to build lasting understanding.

A pulse oximeter reading of SpO₂ 95–100% generally indicates:
Explanation:95–100% SpO₂ is considered normal for most adults at sea level. Readings consistently below 90% usually require medical evaluation.
