Medical Nutrition Therapy (MNT) for diabetes should be: A. Individualized based on patient needs B. The same for every patient
C. Based only on weight D. Focused only on avoiding carbohydrates Answer: A. Individualized based on patient needs Rationale: Diabetes care requires individualized nutrition plans based on glucose goals, lifestyle, medications, and preferences.
3. Diabetes mellitus is a disorder involving: A. Abnormal glucose metabolism B. Excess calcium absorption C. Increased bone production D. Vitamin storage problems Answer: A. Abnormal glucose metabolism Rationale: Diabetes occurs due to problems with insulin production, insulin action, or both, leading to elevated blood glucose. 4. The hormone responsible for lowering blood glucose is: A. Insulin B. Glucagon C. Cortisol D. Epinephrine
7. The nutrient that has the greatest effect on blood glucose is: A. Carbohydrate B. Protein C. Fat D. Water Answer: A. Carbohydrate Rationale: Carbohydrates are broken down into glucose and directly influence blood sugar levels. 8. Carbohydrate counting helps patients with diabetes by: A. Matching carbohydrate intake with insulin and medication needs B. Eliminating all carbohydrates C. Increasing sugar intake D. Preventing digestion Answer: A. Matching carbohydrate intake with insulin and medication needs Rationale: Carbohydrate counting improves glucose control by helping balance food intake and insulin response.
9. One carbohydrate serving equals approximately: A. 15 grams of carbohydrate B. 5 grams of carbohydrate C. 50 grams of carbohydrate D. 100 grams of carbohydrate Answer: A. 15 grams of carbohydrate Rationale: Diabetes meal planning commonly uses 15-gram carbohydrate exchanges. 10. Which food contains primarily carbohydrates? A. Bread B. Chicken breast C. Olive oil D. Eggs Answer: A. Bread Rationale: Bread is a grain product and contains starch, a carbohydrate. 11. A patient with diabetes should avoid:
C. No glucose increase D. Complete insulin blockage Answer: A. A slower rise in blood glucose Rationale: Low GI foods are digested and absorbed more slowly.
14. Fiber improves diabetes management by: A. Slowing glucose absorption B. Increasing blood sugar spikes C. Eliminating insulin requirements D. Increasing saturated fat intake Answer: A. Slowing glucose absorption Rationale: Fiber helps improve glucose response and promotes fullness. 15. Recommended dietary fiber intake for adults generally includes: A. Adequate fiber from fruits, vegetables, and whole grains B. No fiber intake C. Only fiber supplements D. Only animal foods
Answer: A. Adequate fiber from fruits, vegetables, and whole grains Rationale: Fiber supports blood glucose control, digestion, and cardiovascular health.
16. The plate method for diabetes recommends filling half the plate with: A. Non-starchy vegetables B. Desserts C. Refined grains D. Fried foods Answer: A. Non-starchy vegetables Rationale: Non-starchy vegetables provide fiber and nutrients with fewer carbohydrates. 17. The remaining quarter of the diabetes plate should contain: A. Lean protein B. Added sugar C. Candy D. Sweetened beverages
20. Hypoglycemia is defined as: A. Blood glucose that is too low B. High blood pressure C. High cholesterol D. Excess protein intake Answer: A. Blood glucose that is too low Rationale: Hypoglycemia occurs when blood glucose falls below normal levels. 21. A common symptom of hypoglycemia is: A. Shaking and sweating B. Increased bone growth C. Hair growth D. Improved concentration Answer: A. Shaking and sweating Rationale: Low blood glucose activates stress responses causing symptoms such as sweating and tremors. 22. The “15-15 rule” for hypoglycemia involves:
A. Consuming 15 grams carbohydrate and rechecking glucose after 15 minutes B. Eating 15 meals daily C. Avoiding carbohydrates D. Taking 15 units of insulin Answer: A. Consuming 15 grams carbohydrate and rechecking glucose after 15 minutes Rationale: This approach rapidly corrects mild hypoglycemia.
23. Which food is appropriate for treating mild hypoglycemia? A. Glucose tablets B. Cheese only C. Chicken D. Salad without dressing Answer: A. Glucose tablets Rationale: Glucose tablets provide rapidly absorbed carbohydrate. 24. Hyperglycemia refers to: A. Elevated blood glucose levels B. Low blood glucose
Answer: A. Average blood glucose over approximately 2– 3 months Rationale: Hemoglobin A1C reflects long-term glucose control.
27. Weight loss in overweight patients with type 2 diabetes may: A. Improve insulin sensitivity B. Increase insulin resistance C. Increase glucose levels D. Prevent physical activity Answer: A. Improve insulin sensitivity Rationale: Moderate weight loss can improve glucose metabolism. 28. Physical activity helps diabetes management by: A. Improving insulin sensitivity B. Increasing insulin resistance C. Increasing glucose production only D. Preventing nutrient absorption Answer: A. Improving insulin sensitivity Rationale: Exercise helps muscles use glucose more effectively.
29. A balanced diabetes meal includes: A. Carbohydrate, protein, and healthy fat B. Only sugar C. Only protein D. Only fat Answer: A. Carbohydrate, protein, and healthy fat Rationale: Balanced meals support stable glucose levels and adequate nutrition. 30. Which beverage is the best choice for diabetes management? A. Water B.
