Which of the following is not an expected outcome of metabolic acidosis?

In cases of metabolic acidosis, blood pH typically decreases due to an excess of acid or a loss of bicarbonate in the body. Metabolic acidosis is characterized by a lower pH, which reflects the increased acidity in the bloodstream due to the accumulation of metabolic acids or a decrease in bicarbonate ions.

Blood gases change in response to this condition, leading to hyperventilation as the body attempts to compensate by exhaling more carbon dioxide, which is an acidic component in the blood. This compensatory hyperventilation helps to raise the pH back towards normal levels.

Furthermore, metabolic acidosis is often associated with decreased bicarbonate levels as the bicarbonate buffer system is overwhelmed by the excess acid. This decrease is one of the primary indicators of the condition.

Therefore, stating that blood pH will increase is incorrect, as metabolic acidosis is defined by a decrease in pH, making it the option that does not align with the expected outcomes of this condition.
