Final answer:
If a 12 year old boy fell from his bicycle and doesn't remember what he was doing, the parents should monitor him for signs of head injuries and seek medical attention if needed.
Step-by-step explanation:
If a 12 year old boy fell from his bicycle and doesn't remember what he was doing when he fell, the parents should monitor him for any signs of concussion or other head injuries. They should also encourage him to rest and observe him for any changes in behavior or memory loss. If any worrisome symptoms arise, they should seek medical attention immediately.
Bystander effect refers to the phenomenon where people are less likely to offer help in a situation when there are others present. In this case, the parents should not assume that someone else will take care of their son's well-being. They should take responsibility and ensure that he receives proper medical attention if needed.
It is important to note that even if the physical exam doesn't reveal any injuries, there could still be internal injuries or a concussion that may not be immediately apparent. Therefore, the parents should remain vigilant and seek medical attention if any concerning symptoms arise.
