Answer to Question 1
ANS: B
This patient is showing signs and symptoms of hypoxemic respiratory failure due to postoperative atelectasis. This patient's PaO2/FIO2 is below the critical value. Since the patient is still able to move air, intubation and mechanical ventilation, as well as noninvasive positive pressure ventila-tion (NPPV), are not appropriate at this time. This patient is not showing signs of increased work of breathing due to bronchospasm. Therefore, administering bronchodilator therapy is not appro-priate. Initiating continuous positive airway pressure (CPAP) by mask will help to reverse the at-electasis and improve the patient's oxygenation status.
Answer to Question 2
ANS: C
This arterial blood gas shows an uncompensated respiratory acidosis with moderate hypoxemia. A patient with chronic respiratory failure would show an elevated bicarbonate (HCO3) due to the chronic respiratory failure. A patient with acute or chronic respiratory failure would have an elevated partial pressure of carbon dioxide in the arteries (PaCO2) that is higher than what the pa-tient's current HCO3 can compensate for. Hypoxemic respiratory failure will only show a de-creased partial pressure of oxygen in the arteries (PaO2) unless the hypoxemia is so severe that the patient's ventilation is compromised.
