When caring for a client with iron-deficiency anemia, which abnormal laboratory value will the nurse expect?

A. Insulin is responsible for lowering blood glucose levels by promoting the uptake and storage of glucose in cells.

B. Epinephrine (adrenaline) can raise blood glucose levels in response to the "fight or flight" stress response, but it's not primarily responsible for stimulating liver glycogenolysis.

C. Glucagon is produced by the alpha cells in the islets of Langerhans and plays a crucial role in increasing blood glucose levels. It promotes the breakdown of glycogen (glycogenolysis) in the liver and the production of glucose from non-carbohydrate sources (gluconeogenesis).

D. Adrenocorticotropic hormone (ACTH) is produced by the anterior pituitary gland and stimulates the adrenal cortex to release cortisol, which can also contribute to raising blood glucose levels but isn't primarily responsible for liver glycogenolysis.

In the context of diabetes management, understanding the role of glucagon is important because it helps individuals know how to manage hypoglycemia (low blood sugar) by administering glucagon or consuming fast-acting sources of glucose.

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.
