Final answer:
A diabetes patient on a 1500-kilocalorie diet should limit her carbohydrate intake to approximately 375 grams per day.
Step-by-step explanation:
The nurse understands that a diabetes patient on a 1500-kilocalorie diet should limit her carbohydrate intake to approximately 375 grams per day.
Glucose tolerance test is done with the patient being kept on a carbohydrate-rich diet, which is more than 150 gm/day. This indicates that a higher carbohydrate intake may not be suitable for a diabetes patient. Therefore, limiting carbohydrate intake to around 375 grams per day would be more appropriate for a 1500-kilocalorie diet.
