Question

immediately rush a student to the hospital.
allow the student to finish out the quarter/period/half, etc. and then take the student for a medical examination.
remove the student from play and look for signs and symptoms of a concussion.

Explanation:

When a student has a bump or blow to the head or body and isn't acting right, rushing to the hospital immediately may not be necessary without proper assessment. Allowing the student to finish the period can be dangerous as it may worsen the condition. Removing the student from play and checking for concussion signs (as per medical guidelines for head/body trauma assessment) is the first - step for proper evaluation before further action.

Answer:

Remove the student from play and look for signs and symptoms of a concussion.
