Which sign is commonly observed in diabetic ketoacidosis?

• A. Fruity breath.
• B. Jaundice.
• C. Rash.
• D. Leg edema

Answer: (A)

Fruity breath is a classic sign of diabetic ketoacidosis because insulin deficiency drives the body to burn fats, producing ketone bodies, including acetone. Acetone is volatile and exhaled in the breath, giving it a distinctive fruity or sweet odor. This odor is a well-known, commonly observed clinical clue that points toward DKA, especially in the context of dehydration, polyuria, and abdominal pain or vomiting. Jaundice would suggest liver problems, not a hallmark of DKA. A rash is not specific to DKA and could indicate infection, allergy, or another condition. Leg edema is not typical of DKA and points more toward fluid overload, heart, or kidney issues. In DKA, you’d expect signs like dehydration, tachycardia, and rapid, deep breathing due to metabolic acidosis, rather than edema or jaundice.
