Answer:
Refeeding syndrome
Explanation:
If a severely malnourished patient is put on a high-carbohydrate diet, their body may release insulin, which can store electrolytes like phosphorus and water in the cells. This can cause fluid retention and a drop in serum phosphorus levels. This is called refeeding syndrome. If a patient shows these symptoms after being put on a high-carbohydrate diet, the nurse may suspect that they have refeeding syndrome.
