The nurse is caring for a 22-year-old female patient who is brought to the emergency department with a new onset of blurred vision and headache. Use the chart to answer the questions.

The nurse recognizes the patient is demonstrating signs of diabetic ketoacidosis (DKA). Which findings support this recognition? Select all that apply.

(Select All that Apply.)

A. Acetone breath, characterized by a fruity or acetone-like odor on the patient's breath, is a classic sign of DKA. In addition, Kussmaul respirations, which are deep and labored breathing patterns, can occur as the body attempts to compensate for metabolic acidosis in DKA.
C. Nausea and vomiting are common symptoms of DKA and can occur due to metabolic acidosis, electrolyte imbalances, and gastrointestinal disturbances associated with the condition.
F. Tachycardia and hypotension are signs of hemodynamic instability, which can occur in severe cases of DKA due to dehydration, electrolyte imbalances, and the systemic effects of metabolic acidosis.
G. Turning off an insulin pump can lead to insulin deficiency, which is a precipitating factor for DKA, particularly in patients with type 1 diabetes who rely on continuous insulin therapy. This finding is consistent with the development of DKA.
B. Blurred vision and headache can be symptoms of DKA, although they are not specific to this condition. Elevated blood glucose levels and dehydration associated with DKA can lead to osmotic diuresis and subsequent fluid shifts, which may manifest as headache and visual disturbances.
 
D. A history of type 1 diabetes mellitus (DM) predisposes the patient to DKA but the history of appendix removal at age 7 is not directly relevant to the current presentation of DKA.
E. Alcohol ingestion can contribute to the development of DKA by inhibiting gluconeogenesis and promoting ketoacidosis, particularly if the patient is not consuming adequate carbohydrates and insulin. However, it is not a direct sign of DKA.
