Incorrect choices:
a. This choice is incorrect. Polyuria, polydipsia, and polyphagia are the "three P's" associated with hyperglycemia in diabetes mellitus.
b. This choice is incorrect. Nausea, vomiting, and abdominal pain are not typically associated with blurred or distorted vision.
c. This choice is incorrect. Impaired wound healing and increased susceptibility to infections are related to the effects of hyperglycemia on blood flow and immune function, rather than visual disturbances.
