Correct Answer is ["B","C","E"]
Explanation
Choice A rationale
Acetone breath is a characteristic symptom of diabetic ketoacidosis (DKA), not hyperosmolar hyperglycemic syndrome (HHS). In DKA, the body produces ketones, leading to a fruity or acetone-like breath odor. HHS, on the other hand, does not typically involve significant ketone production.
Choice B rationale
Fever can be a manifestation of HHS, often due to an underlying infection or illness that precipitates the hyperglycemic state. Infections are common triggers for HHS, leading to elevated body temperature.
Choice C rationale
Serum glucose levels of 800 mg/dL are indicative of HHS. HHS is characterized by extremely high blood glucose levels, often exceeding 600 mg/dL, without significant ketoacidosis.
Choice D rationale
Serum bicarbonate levels of 15 mEq/L are more indicative of DKA rather than HHS. In HHS, bicarbonate levels are usually within the normal range because there is no significant ketoacidosis.
Choice E rationale
Insidious onset is a hallmark of HHS. The condition develops gradually over days to weeks, unlike DKA, which has a more rapid onset.
