In diabetic management, which patient group should urine ketone testing be emphasized for?

• A. All diabetics daily
• B. Type 2 diabetics during exercise
• C. Type 1 diabetics during illness
• D. Not recommended for any patients

Answer: (C)

Testing urine ketones focuses on spotting diabetic ketoacidosis, a serious complication that arises when insulin is insufficient to prevent fat breakdown and ketone production. This risk is highest in people with type 1 diabetes, especially during intercurrent illness. Illness triggers stress hormones that raise blood glucose and alter insulin needs; if insulin isn’t adjusted adequately, ketones can accumulate quickly and lead to ketoacidosis. Therefore, emphasizing urine ketone testing during illness in type 1 diabetes helps detect rising ketone levels early and prompts timely treatment to prevent progression. In type 2 diabetes, ketosis and ketoacidosis are less common, so routine urine ketone testing during illness isn’t as essential. Routine daily urine ketone testing for all diabetics isn’t standard practice, and saying it’s not recommended for any patients isn’t accurate.
