Florida State Paramedic Practice Exam

In which condition would you observe Kussmaul's respirations?

1. Asthma

2. Heart failure

3. Diabetic Ketoacidosis (DKA)

4. Pneumonia

The correct answer is: Diabetic Ketoacidosis (DKA)

Kussmaul's respirations are characterized by deep, rapid, and labored breathing, and they are primarily associated with metabolic acidosis, particularly in conditions like Diabetic Ketoacidosis (DKA). In DKA, the body attempts to counteract the acidosis caused by the accumulation of ketones and other organic acids. This physiological response results in hyperventilation as the body seeks to expel carbon dioxide, aiming to raise blood pH back towards normal levels. In individuals with DKA, the presence of acidosis stimulates the respiratory center in the brain, leading to this distinctive breathing pattern. Understanding Kussmaul's respirations is crucial for recognizing severe metabolic disturbances and managing conditions that lead to such respiratory changes.
