A 13-year-old girl comes to the clinic complaining of polyuria, polydipsea, and nausea. She does not have a family history of diabetes. A urinalysis reveals significant glucose. The patient also has abnormal glucose tolerance. Which of the following metabolic processes are occurring in this patient?
A. Decreased catabolism of amino acids
B. Decreased triglyceride breakdown
C. Increased peripheral glucose uptake
D. Insulin concentration is usually low and blood is hypo-osmolar
E. Low intracellular concentration of potassium

Not E because insulin drives K+ into the cell

the answer should be E.
this is a young diabetic (so suspect IDDM). Insulin is required to push K+ into the cells, hence in its absence, K+ accumulates in plasma. In DKA you have hyperkalemic acidosis.
insulin + glucose is a drug given in hyperkalemia.

Sorry, but this is why E is wrong:
She doesn't have insulin, so she can't drive K+ into the cells, which explains why she has low intracellular potassium.
