A pediatric client is admitted to the hospital unconscious. The client has a history of type 1 diabetes, and according to the clients mother, has been to two birthday parties in the last few days and has resisted taking the prescribed insulin. At school the client had two more pieces of birthday cake and some ice cream at a class birthday party. What is the likely reason for this client's unconscious state?

A. Insulin shock is another term for hypoglycemia, which would not cause unconsciousness after refusing insulin. B. The history of missed insulin and high-carb intake suggests diabetic ketoacidosis (DKA), where lack of insulin leads to the breakdown of fats, creating ketones and resulting in unconsciousness. C. An insulin reaction is hypoglycemia, which typically causes shakiness, sweating, and confusion, not unconsciousness after high-carb intake. D. Metabolic alkalosis is unlikely in this case and is not related to missed insulin or high blood sugar.
