What should be adjusted if fasting blood glucose levels indicate highs or lows?

  1. Basal insulin

  2. Prandial insulin

  3. Meal quantities

  4. Exercise routine

The correct answer is: Basal insulin

The correct adjustment would be to basal insulin. Basal insulin is the long-acting insulin that is taken once or twice a day to help manage blood sugar levels throughout the day and night. Prandial insulin, which is fast-acting, is typically used before meals to control the rise in blood glucose caused by food. However, adjusting prandial insulin would not address the overall high or low blood glucose levels throughout the day. Adjusting meal quantities and exercise routine may have some impact on blood glucose levels but may not solely address the issue. Therefore, basal insulin is the most appropriate option to adjust in this situation.
