Final answer:
The UAP should report the O2Sat value of 92% on 2 L nasal cannula
Step-by-step explanation:
In this case, the vital sign value that the UAP should report immediately to the nurse is the oxygen saturation (O2Sat) of 92% on 2 L nasal cannula.
When a patient is recovering from ARDS (Acute Respiratory Distress Syndrome), maintaining adequate oxygenation is crucial. An oxygen saturation level of 92% indicates hypoxemia, which means that there is a lower-than-normal level of oxygen in the blood.
Hypoxemia can lead to further complications and compromise the patient's recovery. Therefore, it is important to inform the nurse promptly so that appropriate interventions can be taken to improve oxygenation.
