What is a physical exam finding of DKA?

• A. Cold, clammy skin
• B. Fruity breath odor
• C. Hypertension
• D. Bradycardia

Answer: (B)

A fruity breath odor is a classic physical exam finding in diabetic ketoacidosis (DKA), which is a serious complication of diabetes, particularly type 1 diabetes. This distinct odor is primarily due to the presence of acetone, one of the ketone bodies produced when the body begins to break down fat for energy in the absence of sufficient insulin. In the metabolic state of DKA, the accumulation of these ketones leads to metabolic acidosis, which is associated with various characteristic signs, including this notable fruity smell. In the context of DKA, the body is unable to use glucose effectively, resulting in increased lipolysis and ketone production. The presence of ketosis and the resultant acidosis are also reflected in the breath odor, serving as a critical clue in diagnosing this condition. Recognizing this symptom can aid healthcare providers in differentiating DKA from other diabetic complications and initiating appropriate management quickly.
