What technique is vital for ensuring the safety of a child during transportation to a medical facility?

Using appropriate restraints and positioning is essential for the safety of a child during transportation to a medical facility. This technique ensures that the child is secured in a way that minimizes the risk of injury during transit. Proper restraints, such as safety harnesses or age-appropriate car seats, are designed to protect the child from sudden stops or movements, which could lead to serious harm.

The correct application of restraints also helps maintain the child's stability, preventing them from being jostled around or falling out of their seat. In emergencies, quick and effective transportation can make a significant difference in outcomes, so ensuring that the child is safely secured allows medical personnel to focus on providing care rather than managing a potentially dangerous situation during transport.

This approach stands in contrast to the other options, which do not adequately address the critical aspect of safety in a medical transport scenario.
