Final answer:
The first step after being struck by a piece of metal from a lawn mower is to assess the injury and seek medical attention if necessary.
Step-by-step explanation:
After a student is struck in the lower leg by a piece of metal ejected from a lawn mower, the first step is to assess the injury. It is important to determine the severity of the injury and whether or not there is a risk of infection. The student should seek medical attention, especially if there is significant bleeding or if the wound appears deep.
If the injury is minor and there is no immediate danger, you can clean the wound with soap and water and apply an appropriate dressing to protect the area. Additionally, you should advise the student to watch for signs of infection, such as increasing redness, swelling, or drainage from the wound.
In severe cases, the student may need stitches or further medical treatment. It is important to follow up with a healthcare professional who can provide appropriate care and guidance.
