A nurse is reinforcing teaching about bicycle safety with a school-age child. Which of the following instructions should the nurse include?

A. While it is a good idea to wear a helmet, the color does not significantly impact safety. The helmet should fit securely and cover the forehead, not the ears. B. Riding against traffic is unsafe. Cyclists should always ride in the same direction as traffic to ensure they are visible to drivers. C. The child should always walk the bicycle through crosswalks and intersections to ensure safety and better visibility to drivers. D. Ensuring the balls of the feet touch the ground while seated on the bicycle helps the child maintain balance and provides a safer, more controlled ride.
