Which of the following is a key method to reduce the risk of infection when giving first aid?

The key method to reduce the risk of infection when giving first aid is the practice of handwashing and using personal protective equipment (PPE). This approach is vital because it significantly minimizes the likelihood of transmitting pathogens, both from the caregiver to the patient and vice versa. Proper hand hygiene involves washing hands with soap and water or using an alcohol-based hand sanitizer before and after providing care, which effectively removes germs that could cause infection.

In addition to hand hygiene, personal protective equipment such as gloves serves as a barrier against potential contaminants. By using PPE, first aid providers can protect themselves from bloodborne pathogens and other infectious agents present in bodily fluids. This combination of handwashing and the proper use of protective gear creates a safer environment for both the responder and the individual receiving aid, thus reducing the risk of infection.

While using a face mask may provide some protection, it is not as comprehensive a method as handwashing and PPE in the context of first aid. Antiseptic wipes can help with cleaning specific areas or items but may not be sufficient on their own to ensure overall hygiene during the entire process of providing care. Avoiding the patient altogether does not provide assistance or care, which is counterproductive in a first aid scenario. Therefore, focusing on
