A．Hyperglycemia.
B．Extreme hunger.
C．Hypotension.
D．Hypoglycemia.

The solution, used as a base for most TPN, consists of a high dextrose concentration and may raise blood glucose levels significantly, resulting in hyperglycemia. Fluid overload may cause hypertension, not hypotension. Extreme hunger occurs with hypoglycemia.
