Which should not be given to a person with diabetes?

Phosphorated carbohydrate solution is typically used to treat nausea and vomiting, especially those associated with gastroenteritis or certain medical procedures. This solution is a mixture of glucose and phosphoric acid, which can provide a quick source of carbohydrates. However, for individuals with diabetes, consuming high amounts of carbohydrates can lead to significant fluctuations in blood glucose levels, making it crucial to manage carbohydrate intake carefully.

Since this solution is high in sugar, it is not advisable for someone with diabetes who needs to maintain stable blood sugar levels. Insulin and metformin are medications specifically used to manage diabetes, while lactic acid is not directly related to diabetes management or treatment protocols. Therefore, a person with diabetes should avoid taking phosphorated carbohydrate solution due to its high sugar content, which can undermine glucose control.
