Final answer:
A Chemical burn requires immediate flushing with H2O to dilute the chemical substance and reduce tissue damage. Other types of burns, such as first-, second-, and third-degree burns, require different medical treatments.
Step-by-step explanation:
The type of burn that requires immediate flushing with H2O is (D) Chemical burn. Chemical burns are caused by exposure to corrosive substances such as hydrochloric acid or sodium hydroxide (lye), which can severely damage the skin and underlying tissues. Immediate flushing with water is crucial to dilute the chemical agent and minimize tissue damage and the potential for serious complications.
While first-degree burns are typically painful and swollen, and second- and third-degree burns involve more layers of skin and require medical attention, it is the chemical burn that necessitates immediate flushing with water to prevent further damage. In contrast, first-, second-, and third-degree burns generally benefit from different types of medical care specific to the severity of the burn.
