What is the first step to take for a confused or disoriented patient?

• A. Administer glucose
• B. Place O2 to r/o hypoxia
• C. Perform a head CT
• D. Call for immediate assistance

Answer: (B)

When assessing a confused or disoriented patient, the priority is to rule out any life-threatening conditions, including hypoxia. Administering oxygen is a critical first step because hypoxia can cause confusion or disorientation as a result of inadequate oxygen supply to the brain. Ensuring that the patient has adequate oxygen saturation is essential in stabilizing their condition and gathering further information for diagnosis.

While glucose administration, imaging studies like a head CT, and calling for assistance are important considerations in the management of a confused patient, oxygen therapy directly addresses one of the most common acute causes of altered mental status. If hypoxia is present, correcting it can immediately improve the patient's level of consciousness, making it a vital initial intervention.
