Quizplus · Accepted Answer

Kussmaul respirations are deep and rapid breathing patterns that are seen in diabetic ketoacidosis (DKA). DKA occurs when high levels of ketones are produced due to the breakdown of fats and is typically seen in uncontrolled diabetes. The elevated blood sugar level of 450 mg/dL indicates uncontrolled diabetes in this patient. The Kussmaul respirations are an attempt to blow off excess carbon dioxide, which is a byproduct of the production of ketones. This excess CO2 production leads to a decrease in blood pH, causing it to become more acidic. Therefore, the blood pH is most likely 7.25, which is considered acidic. In addition, the patient is likely excreting large amounts of bicarbonate in their urine, contributing to the acidic pH. The PO₂ (potassium, sodium, chloride, CO2, blood urea nitrogen, serum creatinine, glucose) may be normal or high-normal due to the high blood sugar level.
