Question 1 of 5
A 68 y/o Caucasian male develops acute worsening of his long-standing type 2 diabetes mellitus. Which is least likely to cause this:
Correct Answer: D
Rationale: Worsening diabetes is often due to increased insulin resistance or stress (e.g., Cushing's, infection, cardiac flare-up), which raise glucose levels. Acute adrenal insufficiency (Addison's) causes cortisol deficiency, leading to hypoglycemia, not hyperglycemia, making it the least likely cause.
