Final answer:
The carb portion of ice cream consumed by a diabetic patient depends on the specific type and portion size.
Step-by-step explanation:
In a diabetic patient's diet, carbohydrates should be restricted in order to control blood glucose levels. If a diabetic patient asks a nurse for ice cream, the carb portion they consume will depend on the specific type of ice cream and portion size. Normally, ice cream contains a significant amount of carbohydrates due to the presence of sugar and dairy products.
