Which statement would be correct for a patient with type 2 diabetes who was admitted to the hospital with pneumonia?

Choice A reason: Type 2 diabetes patients typically have sufficient endogenous insulin to prevent ketoacidosis, which is more common in type 1 diabetes due to absolute insulin deficiency. Pneumonia may increase insulin needs, but ketoacidosis is rare, making insulin therapy non-essential for this purpose. Choice B reason: In type 2 diabetes, patients often produce enough insulin to prevent ketoacidosis but face insulin resistance, increasing risk for hyperosmolar hyperglycemic syndrome (HHS) during stressors like pneumonia. HHS results from severe hyperglycemia and dehydration, common in type 2 diabetes under stress, making this statement correct. Choice C reason: Minimal or absent insulin secretion is characteristic of type 1 diabetes, not type 2, where insulin resistance predominates with variable insulin production. Type 2 patients may not require daily insulin, especially early in the disease, making this statement incorrect. Choice D reason: Islet cell antibodies are associated with type 1 diabetes, an autoimmune condition destroying pancreatic beta cells. Type 2 diabetes involves insulin resistance and relative insulin deficiency, not antibody-mediated destruction, making this statement incorrect for a type 2 diabetes patient.
