Musculoskeletal

An 11-year-old boy presents to the emergency room (ER) with a 4-inch laceration on his right arm. He was with his friends doing bicycle stunts when he fell off his bike and cut his arm on a rusty nail from the ramp. In addition, his wrist is swollen, bruised, tender to touch, and warm, with limited mobility. He will most likely need stitches to close the laceration and a splint for the sprain.
In your initial post answer the following questions:
After treatment, as he prepares to leave, you give him last-minute care instructions for laceration and sprain. What would be important for this boy to know to prevent further health concerns with his injuries?
The boy concernedly asks you, “My uncle lost his foot because he got gangrene in it. Am I going to lose my arm if I get an infection in this cut?” How would you respond?
