The nurse is aware that the Tanner staging system for sexual maturity is:

Option A ("Considering the presence of diabetes but treating the child the same as the other children") is not the best approach because children with diabetes require individualized care and monitoring.

Option B ("Limiting fluid intake during school hours") is not an appropriate intervention and could potentially worsen the child's diabetes management. Hydration is important, and fluid intake should be based on the child's needs.

Option C. Asking the child each day what was eaten for breakfast.

Children with type 1 diabetes, especially those prone to morning hypoglycemic episodes, can benefit from close monitoring of their dietary choices and blood glucose levels. Asking the child what was eaten for breakfast allows the school nurse to assess whether the child had an appropriate meal and whether the insulin dosage may need adjustment. It helps identify potential factors contributing to hypoglycemia and provides valuable information for the child's diabetes management.

Option D ("Checking several times a day for injuries because of participation in the physical education program") is a good practice but does not specifically address the management of morning hypoglycemia. It is essential to monitor the child's safety during physical activities, but addressing breakfast choices and insulin management is more directly related to managing morning hypoglycemia.

A. Demonstrating independent dressing is usually not expected at 18 months. Toddlers are still developing fine motor skills and may need assistance with dressing.

B. Using a vocabulary of 300 words is advanced for an 18-month-old. At this age, most children have a more limited vocabulary, typically around 50 words or so.

C. Jump with both feet.

At 18 months of age, children are usually developing their motor skills, including gross motor skills like walking, running, and jumping. Jumping with both feet is an age-appropriate milestone for a toddler of this age.

D. Walking upstairs with one hand held is typically not expected at 18 months. This is a skill that develops later as toddlers gain more confidence in their mobility and coordination.
