Question

your ems team has extricated a 70-year-old patient from the vehicle after it went off the road at a high rate of speed and hit a tree. the patient has an altered mental status and is unable to provide a medical history. you are concerned that a cardiac problem may have precipitated the incident, but you must also rule out:

poor vision.
substance abuse.
distracted driving.
suicidal tendencies.

Explanation:

Analyze the patient presentation

Using the Geriatric Patient Assessment knowledge point, we evaluate a 70-year-old patient involved in a high-speed motor vehicle collision who presents with an altered mental status. In geriatric patients, acute cognitive impairment or altered mental status can be a primary indicator of underlying medical emergencies that precipitated the trauma, rather than just a consequence of the trauma itself.

Evaluate the differential diagnoses

Using the Altered Mental Status Management knowledge point, we must systematically rule out acute, life-threatening, or reversible medical causes that could explain both the altered mental status and the collision. While poor vision, distracted driving, and suicidal tendencies are potential factors in motor vehicle accidents, they do not typically present as an acute altered mental status that prevents the patient from providing a medical history at the scene. Substance abuse (such as alcohol, prescription medication misuse, or illicit drugs) is a critical, reversible cause of altered mental status and impaired driving that must be actively ruled out in the clinical assessment of any trauma patient with unexplained cognitive impairment.

Answer:

• Poor vision.
• Substance abuse. (Correct answer)
• Distracted driving.
• Suicidal tendencies.
