What electrolyte disturbance can occur with rehydration in DKA?

During rehydration in diabetic ketoacidosis (DKA), the primary electrolyte disturbance that can occur is hypokalemia. In DKA, patients often have elevated levels of potassium due to acidosis and the shift of potassium from the intracellular to the extracellular spaces. As treatment progresses and insulin is administered, potassium shifts back into the cells, which can lead to a drop in serum potassium levels.

Monitoring potassium levels is critical during the treatment of DKA, as significant hypokalemia can result in serious cardiac complications and other health issues. Therefore, understanding the dynamics of potassium during the rehydration process is essential for safely managing patients experiencing DKA.

Other electrolyte disturbances, although they can occur in different contexts, are not the primary concerns linked to rehydration in DKA.
