Which respiratory finding is commonly associated with DKA?

• A. Bradypnea
• B. Kussmaul respirations
• C. Apnea
• D. Cheyne-Stokes

Answer: (B)

Metabolic acidosis from diabetic ketoacidosis triggers the lungs to compensate by blowing off CO2, producing a distinctive deep, continuous, and often rapid breathing pattern. This is Kussmaul respiration, the body's way of trying to raise pH by reducing acid load in the blood. It’s a hallmark of DKA because the ketoacids lower the pH and the respiratory system responds with marked, labored breathing to compensate. Other patterns don’t fit this scenario: bradypnea is slow breathing and would worsen acidosis; apnea is pauses in breathing; Cheyne-Stokes is a crescendo–decrescendo pattern with periods of apnea, typically seen with central nervous system issues or heart failure, not DKA.
