Help Quick! DKA nursing dx!

I have a 15 yr old patient with DKA. For the life of me, I cannot figure out a nursing dx for her. My book lists a couple, but they refer mainly to new dx's of DM, which this is not. My care plan book has:

Body temperature alteration, risk for related to decreased sensitivity of thermoreceptors.

Fluid volume deficit related to active loss.

Thought process alteration related to physiologic causes.

****

Fluid volume is a good one since she also has dehydration, but am I wrong in thinking I need to be looking for something that deals with blood sugars?

Please help! I think my brain is fried beyond belief and I can't think straight!
