The appropriate method for securing a patient on a backboard involves using straps across the shoulders, hips, and knees. This technique ensures that the patient is immobilized effectively, minimizing the risk of movement that could exacerbate any potential injuries, especially those related to the spine.

Strapping across the shoulders helps to prevent the upper body from sliding or moving, while securing the hips and knees keeps the lower body stable. This multi-point restraint system allows for even distribution of pressure and support, which is crucial for maintaining the patient's position during transport and providing protection during potential rough handling or movement.

Using only one point of contact, such as a single strap across the shoulders, does not provide adequate support and could lead to unwanted movement. Similarly, elevating the head of the board without securing the body can create a risk of dislodging the spine or causing injury to the patient. Not securing the patient at all poses a significant risk in terms of safety and the potential for exacerbating injuries, particularly in trauma cases. Hence, the use of comprehensive strapping across key points keeps the patient secure and safe during transport.
