What should be done regarding litter straps when preparing for a casualty evacuation?

When preparing for a casualty evacuation, it is essential to ensure that the litter straps are adjusted as needed to secure the casualty properly. Proper adjustment of the straps helps to immobilize the patient during transport, minimizing movement that could exacerbate injuries. This is especially critical in cases of trauma, where stability is paramount to prevent further harm.

Securing the casualty also allows for easier handling and maneuvering during evacuation procedures. Litter straps that are correctly adjusted enable the medical personnel to maintain control over the patient and create a more stable transport environment, lessening the risk of the casualty slipping or falling during movement.

Other responses do not align with best practices in casualty evacuation. Discarding the straps would eliminate a crucial component of patient security. Keeping the straps unsecured or misusing them does not support proper stabilization or safety for the injured individual. Therefore, adjusting the litter straps is the most appropriate and effective action when preparing for evacuation.
