What is a proper way to obtain consent from an individual requiring first aid?

The correct answer emphasizes the importance of introducing oneself and clearly stating the intent to provide help, which helps to establish trust and ensure that the individual understands what assistance they are about to receive. By introducing oneself and mentioning the specific training in first aid, it adds credibility and reassures the individual that they are in capable hands. Additionally, explicitly asking for permission to help aligns with legal and ethical considerations regarding consent, ensuring that the responder respects the autonomy of the person needing care.

The other options, while they may imply a willingness to assist, lack the necessary clarity and professionalism. They do not clearly present the responder's qualifications or seek explicit consent, which is vital in any first aid scenario. Consent is not only a matter of good practice but also a legal requirement in many jurisdictions, reinforcing the importance of option B as the most suitable approach.
