Final answer:
Pulling or tugging at the ear is a common symptom of an ear infection in young children, indicating discomfort or pain which requires assessment by a nurse or doctor.
Step-by-step explanation:
A child who is pulling or tugging at the ear is often exhibiting a symptom of an ear infection. This behavior can indicate that the child is experiencing discomfort or pain in the ear, which is a common symptom of an otitis media, especially in young children who may not be able to articulate their discomfort. Other symptoms that can accompany ear infections include irritability, difficulty sleeping, fever, and fluid draining from the ear. It is important for the nurse to assess the child for these symptoms and possibly further examine the child's ear for infection.
