Final answer:
The nurse should identify option 2: The child has unwashed clothes and a noticeable body odor, as a potential indication of physical neglect.
Step-by-step explanation:
The nurse should identify option 2: The child has unwashed clothes and a noticeable body odor, as a potential indication of physical neglect.
Physical neglect refers to the failure to provide a child with basic needs, such as clean clothes, personal hygiene, and appropriate living conditions. The child having unwashed clothes and a noticeable body odor suggests a lack of proper care and attention from the parents or caregivers.
Unlike the other options, bruises from playing on the playground, excitedly interacting with peers, and having a mild cough and occasional sneezing do not necessarily indicate physical neglect.
