A mаle client with а histоry оf heаvy alcоhol use has been admitted to the hospital for malnutrition and suspected pancreatitis. The client's diagnostic workup suggests alcoholic ketoacidosis as a component of his current health problems. He is somewhat familiar with the effect that drinking has had on his nutrition and pancreas, but is wholly unfamiliar with the significance of acid–base balance. How best could his care provider explain the concept to him?
