Final answer:
Removing debris from a road rash injury prevents infection, as the debris can carry pathogens into the skin. Monitoring for increased redness, swelling, and pain is essential as these are signs of infection that require timely treatment.
Step-by-step explanation:
It is important to remove all debris from a road rash injury to prevent infection. Debris such as dirt, gravel, or other materials can contain pathogens that may cause infections when they are lodged in the skin.
After cleaning and bandaging a cut or abrasion, it is essential to monitor the injury for signs of infection, which include increased redness, swelling, and pain. These symptoms can indicate that pathogens have entered the body through the break in the skin and a possible infection is developing.
Timely intervention and treatment at this stage can help prevent more serious complications.
