Final answer:
Wounds on all parts of the body, apart from the arms, hands, and wrists, should be covered with sterile materials like bandages or gauze to prevent infection from pathogens.
Step-by-step explanation:
Wounds on all parts of the body, excluding arms, hands, and wrists, should be covered to prevent the entry of pathogens that could lead to infection. The coverage could be in the form of bandages, gauze, or other sterile materials that act as a barrier against contaminants. It is essential to properly cover a wound to prevent injuries from worsening and to hasten the healing process. Depending on the location of the injury, wound dressings must be applied appropriately to cover the area well without restricting necessary movement excessively.
