A) Ketone bodies in the urine during acidosis
B) Glucose in the urine during hyperglycemia
C) Protein in the urine during a random urinalysis
D) White blood cells in the urine during a random urinalysis
Answer:
C) Protein in the urine during a random urinalysis

Explanation:
Urine should not contain protein. Proteinuria in a diabetic heralds the beginning of renal insufficiency or diabetic nephropathy with subsequent progression to end stage renal disease. Chronic elevated blood glucose levels can cause renal hypertension and excess kidney perfusion with leakage from the renal vasculature. This leaking allows protein to be filtered into the urine.
