Final answer:
The nurse should request the provider assess the client with a closed leg fracture and peripheral paresthesia first.
Step-by-step explanation:
When triaging clients following a motor vehicle collision (MVC), the nurse should prioritize the client who has a closed leg fracture and reports peripheral paresthesia. Peripheral paresthesia refers to abnormal sensations, such as tingling or numbness, in the limbs. This symptom could indicate nerve damage or compromised blood flow, which requires immediate assessment by a healthcare provider.
