How should ARF be addressed immediately?

How should ARF be addressed immediately?

• A. High concentrations of O2
• B. Low oxygen therapy
• C. Administer morphine
• D. Wait and observe

Answer: (A)

In acute respiratory failure, the immediate goal is to restore adequate oxygenation. Administer high-concentration oxygen right away to raise blood oxygen levels and ease the work of breathing. This quick step addresses the core problem—hypoxemia—and often stabilizes the patient enough to consider further support, such as noninvasive ventilation or airway/mechanical support if needed. Low oxygen therapy would not correct the hypoxemia, morphine can depress respiratory drive and worsen gas exchange, and waiting and observing risks rapid deterioration. After initiating high-concentration oxygen, monitor SpO2, vital signs, and arterial blood gases to guide the next steps.
