AMetabolic acidosis; administer sodium bicarbonate.
BCompensated respiratory acidosis; monitor without intervention.
CMetabolic alkalosis; restrict fluid intake.
DRespiratory acidosis; administer oxygen and consider ventilatory support.
✓ Correct answer: D. Respiratory acidosis; administer oxygen and consider ventilatory support.The ABG results indicate respiratory acidosis due to elevated $$PaCO_{2}$$ (52 mmHg) and low pH (7.28), with normal HCO3-. The primary treatment should be to administer oxygen and consider ventilatory support to enhance ventilation and lower $$CO_{2}$$ levels.
