Severe respiratory distress and altered mental status are critical indicators that suggest the need for intubation. When a patient exhibits severe respiratory distress, it indicates that they are struggling to breathe effectively, which could lead to inadequate oxygenation or ventilation. This is often a sign that the patient's airway is compromised or that they are unable to maintain their own airway due to fatigue or underlying pathophysiology.

Additionally, altered mental status can indicate hypoxia or hypercapnia, where the brain may not be receiving enough oxygen or is affected by elevated carbon dioxide levels. These two signs together create a clinical scenario where immediate intervention is necessary to secure the airway and ensure proper oxygenation and ventilation. Intubation would help protect the airway, facilitate mechanical ventilation if needed, and support the patient's respiratory needs until the underlying cause can be treated. The other choices do not provide the critical combination of severe distress and altered consciousness that indicates an urgent need for intubation.
