Final answer:
In assessing a toddler for a possible ear infection, a nurse would note ear tugging option (B), which is a nonverbal sign of discomfort such as that caused by acute otitis media.
Step-by-step explanation:
When assessing a toddler for a possible ear infection, such as acute otitis media (AOM), the nurse would note certain behaviors that are indicative of the condition. One key behavior to look for is ear tugging option (B). This action is a nonverbal sign suggesting AOM and indicates that the child is experiencing discomfort or pain in their ear. Other behaviors that may signal an ear infection include holding, rubbing of the ear, increased crying, irritability, and signs of distress. While other symptoms like fever, nausea, vomiting, diarrhea, and loss of appetite can be associated with AOM, particularly in infants, ear tugging is a much more specific sign consistent with ear pain.
