Administering first aid to an individual with an open wound requires careful action to minimize the risk of infection and promote healing. Here are the essential steps to follow:

Protect Yourself: Wear gloves or use a barrier to prevent exposure to blood or bodily fluids.

Control Bleeding: Apply gentle, direct pressure to the wound using a clean, sterile dressing.

Clean the Wound: Rinse the wound with clean water to remove debris, if available. 

Apply a germ-killing Agent:  Use an antiseptic solution like povidone-iodine or an antibiotic ointment to reduce the risk of infection. 

Use a Drying Agent: If needed, lightly dab the area with sterile gauze to remove excess moisture, or use a drying antiseptic like Betadine. 

Apply a dressing: Cover the wound with a sterile bandage or gauze to protect it from contamination.

Seek Medical Attention: For severe wounds, uncontrolled bleeding, or signs of infection, seek a healthcare professional immediately.
