When administering supplemental oxygen to a hypoxemic patient with a chronic lung

oxygen may depress his or her breathing.
D. avoid positive-pressure ventilation because the majority of patients with chronic lung
disease are at increased risk for lung trauma. - Ans - B. adjust the flow rate
accordingly until you see symptom improvement, but be prepared to assist his or her
