Final answer:
The nurse should recommend wearing helmets during high-risk activities to prevent future concussions, as they offer significant protection against traumatic head injuries.
Step-by-step explanation:
The nurse's best response when a patient asks what can be done to help prevent future concussions would be "Wearing a helmet during high-risk activities can provide significant protection." This preventive measure is essential since studies and safety protocols in high-impact sports, like those implemented by the NCAA and NFL, emphasize the importance of proper headgear in reducing the risk of concussions. Helmets that meet high safety ratings are instrumental in protecting against traumatic head injuries, particularly in sports. It's also important to ensure that the helmet fits correctly and is worn consistently during high-risk activities like football, biking, and skating. Additionally, taking steps to avoid unnecessary risks and ensuring safe environments can contribute to concussion prevention.
