Which electrolyte imbalance is often seen in diabetic ketoacidosis?

In the context of diabetic ketoacidosis (DKA), hyperkalemia is commonly observed. This condition occurs due to a combination of factors related to insulin deficiency and acidosis. As the body fails to utilize glucose effectively, there is a shift of potassium from the intracellular space to the extracellular fluid in an attempt to maintain electroneutrality. Additionally, in acidosis, hydrogen ions move into cells, causing potassium to leave the cells and enter the bloodstream. This results in elevated potassium levels in the serum.

Monitoring potassium levels is critical in patients with DKA, as the initial hyperkalemia can transition to hypokalemia, particularly when insulin therapy is initiated. Insulin drives potassium back into the cells, and without proper monitoring and replacement, this can lead to dangerously low potassium levels.

Understanding the mechanisms of electrolyte imbalances in conditions like DKA is essential for effective management and treatment. In contrast, the other options listed do not reflect the typical changes seen in DKA, making them less relevant in this specific clinical context.
