Final answer:
Families of patients with end stage renal disease should be instructed to provide foods high in carbohydrates, with careful management to avoid complications related to diabetes and kidney function.
Step-by-step explanation:
The nurse should teach the family of a patient with end stage renal disease to offer foods that are high in carbohydrates. Carbohydrates, along with proteins, help maintain connective tissue and are essential to blood clotting. However, it is important to monitor the amount and type of carbohydrates consumed, as excessive carbohydrates, especially in diabetes mellitus patients, can lead to hyperglycemia and exacerbate kidney problems. In the context of end stage renal disease, energy requirements can be met with appropriate amounts of proteins and fats, while closely managing carbohydrate intake to avoid further complications.
