Which topic describes tools used to diagnose stroke in prehospital settings?

• A. Stroke Diagnostic Tool
• B. Stroke (CVA)/ Transient Ischemic Attack (TIA)
• C. Naloxone Nasal Instructions
• D. Stab/ Gunshot/ Penetrating Trauma

Answer: (B)

The main idea here is recognizing stroke in the field and distinguishing it from a TIA, so the patient gets rapid, appropriate care. In prehospital settings, identifying that a patient has a stroke (or a TIA that could progress) is what guides urgent transport and activation of stroke protocols. This topic—Stroke (CVA) / Transient Ischemic Attack (TIA)—focuses on the clinical presentation, warning signs, and the urgency of diagnosis in the field, which is why it’s the best fit for describing how stroke is diagnosed before reaching the hospital.

The other options don’t fit the scenario as well. Naloxone nasal instructions are specific to opioid overdose management, not stroke. Penetrating trauma covers injuries from stab or gunshot wounds, which are unrelated to diagnosing stroke. Although a stroke diagnostic tool exists, the question’s framing points to the broader clinical category you’re assessing in the field, not a single tool.
