A casualty has a shooting injury to his left foot but can hop on his right leg. How should you proceed?

In this scenario, option C emphasizes the importance of assessing safety for both the rescuer and the casualty when considering how to proceed with moving the injured individual. Given the context of a shooting injury to the foot, stability and minimization of further injury are paramount. Choosing the safest method means evaluating the terrain, the proximity of danger, and the condition of the casualty.

Ensuring both yours and the casualty's safety leads to the selection of the most appropriate method of movement. If a back carry, drag, or cart is accessible and they align with safety protocols for the situation, those methods could be utilized. However, the overarching principle in emergency situations is to prioritize safety first. This means that one should avoid putting either the rescuer or the casualty in further risk while still seeking a way to provide necessary medical attention or evacuate the area.

In contrast, some other methods mentioned may not guarantee safety. For instance, a back carry might impose strain on the rescuer or further injure the casualty if not executed correctly. Similarly, dragging someone by the arms can cause additional pain or harm depending on the injury sustained. Using a cart could be a consideration, but it relies on the availability of resources and the environment's suitability for using such methods. Thus
