For last week’s practice question, we quizzed participants on how glucose levels impact gastric emptying. 46% of respondents chose the best answer. We want to clarify and share this important information, so you can pass it on to people living with diabetes and your colleagues, plus prepare for exam success!
Before we start though, if you don’t want any spoilers and haven’t tried the question yet, you can answer it below: Answer Question
Glucose fluctuations can impact gastric emptying rates.
Which of the following is the MOST accurate statement that describes the impact of glucose levels on gastric emptying rates?
If you are thinking about taking the certification exam, this practice test question will set you up for success. Test writers anticipate possible answers based on the details in the question. They will wave those “juicy answers” right under your nose. Your job is to weed through the particulars, pluck out the most important elements and choose the BEST answer.
Answer 1 is incorrect. 34.05% chose this answer. “Chronic hyperglycemia is associated with delayed gastric emptying.” This tempting answer implies that chronic hyperglycemia only causes delayed gastric emptying. However, more recent data suggests that acute and chronic hyperglycemia can also cause faster gastric emptying, resulting in post meal hyperglycemia and increased hunger.
Answer 2 is incorrect. 14.82% of you chose this answer. “Hypoglycemia is associated with delayed gastric emptying and increased glucagon secretion.” This answer has elements of accuracy. If someone injects bolus insulin before eating a meal, and they have gastroparesis, this can result in post meal hypoglycemia due to a mismatch of insulin action and carbohydrate absorption. The second part of the answer is inaccurate, since increased glucagon secretion is associated with hyperglycemia.
Answer 3 is correct. About 46.23% of respondents chose this. “Hyperglycemia can lead to delayed or rapid gastric emptying.” YES, great job. Acute and chronic hyperglycemia can wreak havoc on stomach emptying, causing either delayed or expediated bolus propulsion to the duodenum.
Finally, Answer 4 is incorrect. 4.9% chose this answer. “Gastric emptying rates are usually about 10-40 kcals per minute regardless of glucose levels.” This answer sounds accurate, but gastric emptying rates are approximately 1-4 Kcals per minute.
We hope you appreciate this week’s rationale! Thank you so much for taking the time to answer our Question of the Week and participate in this fun learning activity!
