Answer and Explanation

Correct Answer : A,B,C,D

B. PaCO₂ reflects the respiratory component of acid-base balance and helps assess respiratory acidosis or alkalosis.
C. HCO₃ (bicarbonate) reflects the metabolic component of acid-base balance and is essential for evaluating metabolic acidosis or alkalosis.
