How would you treat a 70-year-old male who fell off a stool and displays altered mental status?

The appropriate choice of treatment in this scenario involves providing oxygen and IV 0.9% sodium chloride. In a 70-year-old male who has fallen and exhibits altered mental status, it is crucial to ensure adequate oxygenation and hydration.

Oxygen is vital because altered mental status may indicate inadequate cerebral perfusion or oxygenation, especially if there is a possibility of head injury or another underlying medical condition. Administering IV 0.9% sodium chloride can help with fluid resuscitation, especially if there is a concern about blood loss or dehydration following the fall.

While other treatments, such as administering naloxone, could be applicable if an opioid overdose were suspected, there is not enough information to assume that is the case solely based on the details provided. Administration of oral glucose would usually be considered if there were clear signs of hypoglycemia, and immediate intubation is typically reserved for severe airway compromise, which has not been indicated in this scenario. Therefore, the combined administration of oxygen and IV fluids supports overall patient stabilization while further assessment and treatment are conducted.
