She has had several episodes of sweating, dizziness, and nausea in the past 2 months that occur during the day and always resolve after she drinks orange juice. She is compliant with her diet and insulin regimen. The physician recommends lowering her insulin dose in certain situations. This recommendation is most important in which of the following situations?? A: During a viral infection, B: After large meals, C: Before exercise, D: After a stressful exam, E: During pregnancy,  <response>: This is a clinical vignette about a 22-year-old woman with type 1 diabetes mellitus who is experiencing hypoglycemic episodes characterized by sweating, dizziness, and nausea that resolve after drinking orange juice. She is compliant with her insulin regimen. The question asks in which situation it would be most important to lower her insulin dose to prevent hypoglycemia.Choice A is incorrect because viral infections can transiently increase insulin requirements and lower glucose levels, so lowering insulin dose during an infection could worsen hypoglycemia. Choice B is incorrect because large meals require larger insulin doses to cover the carbohydrate load. Lowering insulin after large meals could lead to hyperglycemia.Choice C is correct because exercise can rapidly lower blood glucose levels by increasing glucose uptake by muscles. Lowering the insulin dose before exercise prevents exercise-induced hypoglycemia. Choice D is incorrect because hypoglycemia during a stressful exam would likely be due to excess insulin relative to decreased oral intake rather than increased insulin sensitivity. Lowering insulin dose could lead to hyperglycemia.Choice E is incorrect because insulin requirements usually increase during pregnancy, so lowering insulin could worsen hyperglycemia. C: Before exercise
