Final answer:
First degree burns are characterized by localized redness, swelling, and pain, which are signs of inflammation. They typically heal on their own. Monitoring these symptoms is critical as increasing severity may indicate complications.
Step-by-step explanation:
The symptoms of first degree burns include localized redness, swelling, and pain. These are part of the four cardinal signs of inflammation, which were documented by Cornelius Celsus in the first century AD. First degree burns affect only the outer layer of the skin, known as the epidermis. Despite the discomfort, these burns usually heal on their own within a few days. Local heat is another indication that inflammation is occurring at the site of the burn, while fever can be a systemic indication of inflammation.
Notably, the rule of nines is often used to measure the extent of burn injuries by correlating particular body areas with percentages in multiples of nine to estimate the total surface area affected. In dealing with a burn, it is essential to monitor for signs that the inflammation is increasing, which could indicate infection or other complications requiring medical attention.
