A patient suffers bilateral femoral fractures during a tornado. What is the most appropriate intervention based on disaster triage principles?

In the context of disaster triage principles, the most appropriate intervention is to initiate two large caliber intravenous lines for the administration of Ringer's lactate solution. This action aligns with the vital need to address life-threatening conditions in severely injured patients, particularly when they have suffered major trauma such as bilateral femoral fractures.

In disaster situations, patients are often assessed using the triage system to categorize their needs based on the severity of their injuries and the urgency of their medical care. Accurate and timely fluid resuscitation is crucial for patients with significant hemorrhagic shock or potential shock, which can result from severe fractures. Establishing large bore IV access allows for the rapid infusion of fluids, helping to stabilize blood pressure and improve perfusion to vital organs.

The choice to focus on IV fluid administration is also consistent with the triage principle of addressing the most critical needs first, as complications from shock can lead to rapid deterioration if not managed promptly. By prioritizing resuscitation, trauma care providers can help ensure better outcomes for patients in critical scenarios like this one.
