Acid-Base Disorder Changes Explained
This question requires identifying the correct primary changes associated with specific acid-base disorders.
Analysis of Statement A: Metabolic Acidosis
Metabolic acidosis is primarily characterized by a decrease in plasma bicarbonate ($\text{HCO}_3^-$) concentration. This reduction in the base component leads to a lower blood pH.
Statement A is correct.
Analysis of Statement B: Metabolic Alkalosis
Metabolic alkalosis is defined by an increase in plasma bicarbonate ($\text{HCO}_3^-$) concentration. The statement incorrectly suggests a decrease.
Statement B is incorrect.
Analysis of Statement C: Respiratory Alkalosis
Respiratory alkalosis results from hyperventilation, leading to excessive elimination of carbon dioxide ($\text{CO}_2$). This causes a decrease in the partial pressure of carbon dioxide ($\text{PCO}_2$) in the arterial blood, raising the blood pH.
Statement C is correct.
Analysis of Statement D: Respiratory Acidosis
Respiratory acidosis occurs due to hypoventilation, resulting in a retention of carbon dioxide ($\text{CO}_2$). This leads to an increase in the partial pressure of carbon dioxide ($\text{PCO}_2$) and a decrease in blood pH. The statement incorrectly suggests a decrease in $\text{PCO}_2$.
Statement D is incorrect.
Conclusion
The analysis shows that statements A (Metabolic acidosis decreased plasma bicarbonate) and C (Respiratory alkalosis decreased $\text{PCO}_2$) are correct descriptions of primary changes in these disorders.
Therefore, the correct option includes only A and C.
