Final answer:
The nurse should assess the patient with a central venous O2 saturation (ScvO2) of 69% while on bilevel positive airway pressure (BiPAP) first.
Step-by-step explanation:
In this situation, the nurse should assess the patient with a central venous O2 saturation (ScvO2) of 69% while on bilevel positive airway pressure (BiPAP) first.
Low ScvO2 levels indicate inadequate oxygen supply to the tissues and can be a sign of poor respiratory function or decreased cardiac output. This patient may be at risk for respiratory distress or worsening of their condition while on BiPAP, and prompt assessment and intervention are necessary.
