A nurse is caring for a child in acute respiratory failure. Which blood gas analysis indicates the child is still in respiratory acidosis? A) pH 7.50, CO₂ 48 B) pH 7.30, CO₂ 30 C) pH 7.32, CO₂ 50 D) pH 7.48, CO₂ 33

Respiratory failure is a process that involves pulmonary dysfunction generally resulting in impaired alveolar gas exchange, which can lead to hypoxemia or hypercapnia. Acidosis indicates the pH is less than 7.35 and the CO₂ is greater than 45. If the pH is less than 7.35 but the CO₂ is low, it is metabolic acidosis. Alkalosis is when the pH is greater than 7.45. If the pH is high and the CO₂ is high, it is metabolic alkalosis. When the pH is high and the CO₂ is low, it is respiratory alkalosis.
