A nurse is caring for a patient with diabetes and has a diagnosis of nephropathy. What would the nurse expect the urinalysis report indicate?

Albumin

Describe how insulin regulation is altered in diabetes state.

Insulin regulates the production and storage of glucose. In diabetes, either the pancreas stops producing insulin or the cells stop responding to insulin. Hyperglycemia results and can lead to acute metabolic complications such as diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome. Long-term complications can contribute to macrovascular or microvascular complications.

What are two main problems related to insulin type 2 diabetes?

Insulin resistance and impaired insulin secretion

May improve blood glucose levels, decrease the need for exogenous insulin, help reduce cholesterol levels

Retinopathy

Microvascular changes develop in the eyes.

What priority action should the nurse take in caring for Christine?

Monitoring urinary output by means of an indwelling catheter, evaluating serum electrolytes, testing for glycosuria and acetonuria, blood glucose testing, and vital signs.
