College Answer

Adrenal Insufficiency

Hyponatraemia
Hyperkalaemia
Non anion gap acidosis Hypoglycaemia Hypercalcaemia

Refeeding Syndrome

Hypophosphataemia Hypokalaemia Hypomagnesaemia Hyperglycaemia

Tumour Lysis Syndrome

Hyperphosphataemia Hyperkalaemia Hypocalcaemia Hyperuricaemia Metabolic acidosis

Ethylene Glycol Toxicity

High anion gap acidosis High osmolar gap Hypocalcaemia

Discussion

The tabulated answer from the college is comprehensive, and would be difficult to improve upon.

Instead, I will offer links to detailed discussions of the abovementioned syndromes.
