Final answer:
Diabetic ketoacidosis (DKA) is indicated by symptoms including nausea, vomiting, abdominal pain, Kussmaul respirations, and coma with a BGL of 400 mg/dL; treatment focuses on insulin administration and fluid replacement.
Step-by-step explanation:
The symptoms described, which include nausea, vomiting, abdominal pain, Kussmaul respirations (a type of deep, labored breathing associated with severe metabolic acidosis), and coma with a blood glucose level (BGL) of 400 mg/dL, suggest a diagnosis of diabetic ketoacidosis (DKA).
This condition can be severe and potentially fatal if not properly treated. The primary treatment for DKA involves the administration of insulin, to reduce high blood glucose levels, and fluid replacement, to address dehydration. Close monitoring of electrolytes is also necessary since ketoacidosis can lead to severe electrolyte imbalances. It is crucial to regularly manage blood glucose levels and administer insulin correctly to prevent the development of DKA.
