A 5-year-old girl is brought into the Emergency Department with stomach pain and vomiting. Her mother informs you that she has been losing weight recently and has been drinking a lot of fluids and urinating frequently. During the examination, you observe that she is drowsy and visibly dehydrated. She is breathing deeply and rapidly. A blood glucose test reveals very high levels. The urine dipstick shows 3+ ketones, and a venous blood gas test indicates a pH of 7.14. The diagnosis is diabetic ketoacidosis.
How long should it take to correct this fluid deficit?
