What should be worn when caring for someone with life-threatening bleeding?

Wearing gloves is essential when caring for someone with life-threatening bleeding to protect both the caregiver and the individual receiving aid. Gloves act as a barrier against exposure to blood and bodily fluids, which can contain infectious diseases. This form of personal protective equipment is crucial in maintaining safety during the provision of first aid, especially in emergency situations where there is a high risk of contact with blood.

Other protective gear, such as masks or aprons, may be appropriate in different scenarios or specific health care settings, but they are not routinely necessary for managing external bleeding in the same way that gloves are. Sterile bandages can be used for dressing the wound once immediate care has commenced, but they do not provide the protection needed for the person administering aid. Therefore, the correct choice emphasizes the importance of gloves in ensuring safety and hygiene while performing first aid for severe bleeding.
