Final answer:
The first and foremost step in administering first aid for an open fracture is to assess and secure the victim's breathing before attending to the injury directly.
Correct option is B
Step-by-step explanation:
In the context of first aid for an open fracture, prioritizing the assessment of the victim's breathing is paramount. Establishing a clear airway and ensuring adequate breathing take precedence as immediate actions, as they are foundational to the victim's overall well-being. A compromised airway can swiftly escalate into a life-threatening situation, emphasizing the critical importance of prompt intervention. Once the victim's breathing is secured, attention can be directed toward managing the open fracture. This includes addressing any bleeding, providing stabilization with a splint to prevent further injury, and covering the wound to minimize infection risks.
However, the sequence underscores the fundamental principle that ensuring the victim's ability to breathe takes precedence over other aspects, aligning with the overarching goal of preserving life and preparing the individual for subsequent medical care.
