If the SpO2 monitor is non-functional, what signs may indicate the need for high concentration oxygen?

1. Coughing and sneezing

2. Hypotension and altered level of awareness

3. Headache and nausea

4. Normal vital signs

The correct answer is: Hypotension and altered level of awareness

The choice indicating hypotension and an altered level of awareness is correct because these signs can be indicative of inadequate oxygenation or hypoxia, which would necessitate the administration of high concentration oxygen. Hypotension may suggest insufficient blood flow and oxygen delivery to vital organs, while an altered level of awareness could point toward significant oxygen deprivation that could lead to confusion, lethargy, or even loss of consciousness. Monitoring these vital signs is crucial in assessing a patient's respiratory status and overall clinical picture, particularly when a SpO2 monitor is not functional and cannot provide real-time oxygen saturation readings. In contrast, the other options do not reliably suggest an immediate need for high concentration oxygen. Coughing and sneezing might indicate airway irritation or infection rather than a direct need for supplemental oxygen. Headache and nausea can occur for various reasons and do not specifically point to severe hypoxia. Normal vital signs would generally indicate that there is no urgent need for oxygen intervention, as they typically reflect a stable patient condition.
