What should you do if you notice a child scratching their head vigorously?

Selecting the option to put on gloves and check for lice is appropriate because vigorous scratching of the head can be a sign of an infestation. Lice are a common issue among children, and being proactive in identifying them can help prevent spreading to others. By checking for lice, you can address a potentially contagious situation swiftly and efficiently.

Ignoring the child's behavior could lead to further discomfort for the child and the risk of spreading lice to other children. Changing their clothes does not directly address the cause of the scratching and is not a relevant response to the symptom presented. Sending the child home immediately may be necessary if lice are found, but identifying the issue first is essential before taking that action. Putting on gloves also demonstrates proper hygiene and safety practices when dealing with potential infestations.
