Final answer:
The first course of action for Jake, who has a human bite on his fist, should be to debride and irrigate the wound thoroughly. Administering a tetanus injection may also be necessary, depending on Jake's vaccination history and the nature of the bite.
Step-by-step explanation:
The first course of action for Jake, who has a human bite on his fist, should be to debride and irrigate the wound thoroughly. Debridement involves removing any dead tissue from the wound, while irrigation involves cleaning the wound with a sterile solution. This is to prevent infection and promote healing.
Administering a tetanus injection (option D) may also be necessary, depending on Jake's vaccination history and the nature of the bite. Tetanus is a potentially serious bacterial infection that can occur from contaminated wounds. However, it is not always an immediate first step.
In some cases, initiating broad-spectrum antibiotics may also be necessary if there is a high risk of infection or if signs of infection are present. Leaving the wound open for drainage (option C) may be appropriate in certain cases, but this would typically be determined by a healthcare professional based on the specific details of the wound.
