Which of the following is included in the first aid basics that a watchstander should know?

• A. How to operate advanced medical equipment
• B. CPR and managing common injuries
• C. Administering medications
• D. Understanding legal medical responsibilities

Answer: (B)

B is the correct choice because CPR (Cardiopulmonary Resuscitation) and the ability to manage common injuries are fundamental skills in first aid that every watchstander should possess. These skills focus on immediate, life-saving actions that can be taken in emergency situations where someone is injured or in distress.

Knowing how to perform CPR is crucial since it can significantly increase the chance of survival in cases of cardiac arrest. Additionally, managing common injuries such as cuts, burns, or sprains allows a watchstander to provide immediate care and stabilize a situation until further medical help can arrive.

The other options involve more specialized knowledge or responsibilities that are typically beyond the basic requirements for watchstanders. Operating advanced medical equipment and administering medications require clinical training and certification, while understanding legal medical responsibilities pertains more to liability and legal ramifications in a medical setting, which, while important, is not a primary focus of first aid basics.
