Question

Quizplus · Accepted Answer

The patient's lab results indicate severe respiratory distress with hypoxemia (low PaO2), hypercapnia (high PaCO2), and acidosis (low pH). Given the severity of the patient's condition, including shallow and rapid respirations, mechanical ventilation with assist-control and sedation (choice A) is the most appropriate next step to ensure adequate ventilation and oxygenation. Non-invasive options like NPPV, CPAP, or a high-flow non-rebreathing mask may not provide sufficient support given the severity of the patient's condition.
