Metabolic acidosis may be caused by:
1) an increase in fixed (nonvolatile) acids.
2) an increase in blood carbon dioxide (CO₂) .
3) excessive loss of bicarbonate (HCO₃^-) .

Question

Metabolic acidosis may be caused by: 1) an increase in fixed (nonvolatile) acids. 2) an increase in blood carbon dioxide (CO₂). 3) excessive loss of bicarbonate (HCO₃^-).

Quizplus · Accepted Answer

Metabolic acidosis can be caused by an increase in fixed acids (option 1) or excessive loss of bicarbonate (option 3). An increase in blood carbon dioxide is associated with respiratory acidosis, not metabolic acidosis (option 2 is incorrect). Therefore, the best choice is D, 1 and 3 only.
