Patient’s electrolytes profile is affected by many factors
Fistula drainage, uncontrolled glucose level that he may require more insulin, possible on steroids, etc. All these factors lead to electrolytes disturbances. I can’t help you in electrolytes
Adjustments as we don’t complete patient history, Medications, lab profile, electrolytes in IVF or PN patient received, under cardiac monitor or not.
I may help if I have a hint for some information about the case.
