A client with diabetic ketoacidosis is exhibiting Kussmaul breathing and reports a severe headache with nausea. Which assessment finding warrants immediate nurse intervention?

• A. Muscle stiffness
• B. Fruity breath
• C. Abdominal pain
• D. Mental stupor

Answer: (B)

Fruity breath is a classic sign of diabetic ketoacidosis, reflecting acetone buildup from ongoing ketogenesis and a state of metabolic acidosis. When you notice this breath, it signals that the patient’s ketosis is active and requires prompt, decisive nursing action to stabilize and treat the DKA. That means immediately verifying airway and breathing status, securing IV access, and initiating urgent care steps such as fluid resuscitation with isotonic saline, obtaining stat labs (glucose, electrolytes, arterial blood gas, serum ketones), and preparing for insulin therapy per protocol while monitoring for shifts in potassium and other electrolytes. Muscle stiffness, abdominal pain, and mental stupor can occur in DKA, but fruity breath specifically alerts you to active ketosis needing rapid intervention to prevent further deterioration.
