Self-monitoring during activity and rest includes which two measures?

• A. Heart rate and blood pressure
• B. SpO2 and titration
• C. Respiratory rate and oxygen flow
• D. Temperature and sleep quality

Answer: (B)

Monitoring oxygenation during activity and rest hinges on two things: the oxygen saturation level and the corresponding adjustment of delivery to keep that level in the target range. SpO2, measured with a pulse oximeter, tells you how well the blood is carrying oxygen at any moment. Titration is the process of adjusting the oxygen delivery (flow or FiO2) based on that SpO2 reading to maintain the desired saturation. Together, they capture both the feedback you need from the body and the action you take to keep oxygenation safe and effective.

Other options don’t provide this direct link between oxygenation status and management. Heart rate and blood pressure are general vitals and don’t reflect how well tissues are oxygenated. Respiratory rate alone isn’t enough to judge oxygenation without SpO2, and oxygen flow or temperature and sleep quality don’t convey the monitoring-and-adjustment loop essential for self-managed oxygen therapy.
