How should you protect yourself when giving first aid?

Using personal protective equipment (PPE) is essential when providing first aid to protect both the rescuer and the patient. PPE includes items such as gloves, masks, goggles, and gowns, which serve as barriers against potential pathogens and bodily fluids that may be present during treatment. This is crucial in preventing the transmission of infectious diseases, especially in situations where blood or other bodily fluids might be involved.

In addition to personal protection, it is also important to maintain hygiene and minimize contact with any contaminants. The other options do not adequately address the importance of safety and protection during first aid, as ignoring fluids, only helping known patients, or wearing a mask at all times does not ensure comprehensive protection in all scenarios. Being equipped with appropriate PPE is the most effective means of safeguarding against health risks when rendering first aid.
