A confused 60-year-old female complains of generalized weakness after working outside on a hot, humid day. Her skin is hot and moist. After moving her to your air-conditioned ambulance, what should you do next?

• A. Dry her skin.
• B. Cover her with a dry sheet.
• C. Apply cold packs to her groin.
• D. Assess her vital signs and blood glucose level

Answer: (D)

When a patient is confused after heat exposure, the priority is to quickly assess stability and rule out a reversible cause. The quickest way to do this in the field is to obtain vital signs to gauge how hard the body is working to cope with the heat and to perform a finger-stick glucose. Vital signs tell you if she’s showing signs of shock, dehydration, or respiratory compromise, which drives urgent management like cooling, fluids, or airway support. Checking blood glucose is essential because hypoglycemia can present with confusion and is rapidly treatable, and it won’t wait for a full workup. Knowing the glucose level and the patient’s hemodynamic status guides the next steps—whether you start cooling, administer fluids, or address airway and breathing.

Cooling measures and drying the skin can be important parts of treatment, but they don’t address the immediate question of whether the patient is stable and whether hypoglycemia or another acute issue is driving the confusion. Start with the assessment, then tailor the interventions based on vitals and glucose results.
