Potassium (K+)

  1. Potassium plays an exchange role in maintaining acidbase balance.
  2. The body changes the potassium level by drawing hydrogen ions into the cells or by pushing them out of the cells (potassium movement across cell membranes is facilitated by transcellular shifting in response to acid-base patterns).
  3. The potassium level changes to compensate for hydrogen ion level change.
  • During acidosis, the body protects itself from the acidic state by moving hydrogen ions into the cells. Therefore, potassium moves out to make room for hydrogen ions and the potassium level increases.
  • During alkalosis, the cells release hydrogen ions into the blood in an attempt to increase the acidity of the blood; this forces the potassium into the cells and potassium levels decrease.


When the client experiences an acid-base imbalance, monitor the potassium level closely, because the potassium moves in or out of the cells in an attempt to maintain acid-base balance. The resulting hypokalemia or hyperkalemia predisposes the client to associated complications.
