Unit: 6 Therapeutic Nursing care Part: 3 Care of patient with Fluid and Electrolyte imbalance Key terms: define acidosis: In this acid-base imbalance, the concentration of hydrogen ions (H+) increases and its pH becomes less than 7.35. In this, arterial pH is also low due to decreased concentration of bicarbonate (HCO3-), which is called metabolic acidosis. In respiratory acidosis, the concentration of PCO2 increases, due to which arterial pH is
