Final answer:
When immobilizing a small child with a head and neck injury, it is important to keep the person still, stabilize the neck, and call for emergency medical assistance.
Step-by-step explanation:
When immobilizing a small child with a suspected head and neck injury, one consideration is to keep the person very still. This is important because any movement can worsen the injury and potentially cause paralysis or other serious complications. Another consideration is to place heavy towels on both sides of the neck or hold the head and neck to prevent them from moving. This helps to stabilize the spine and minimize further damage. It's also crucial to call 911 or your local emergency medical assistance number to ensure that professional medical help arrives promptly.
