DKA (acidosis) > Potassium shifts out of the cell > hyperkakemia

FA 2019, pg 578





DKA is a state of decreased insulin; since we know that insulin causes a shift of K+ into the cells low levels of insulin will prevent this and result in hyperkalemia. In addition, due to hyperglycemia and high ECF osmolality water will shift out of the cells into the ECF and K+ shifts out with the water which will futher increase the hyperkalemia
