A post-operative client develops acute chest pain on deep inspiration with tachycardia and hypoxemia. What should be the first intervention?

• A. Administer oxygen.
• B. Obtain a blood pressure reading.
• C. Connect to cardiac monitor.
• D. Raise head of bed to 90 degrees.

Answer: (D)

Optimizing breathing through positioning is the key idea here. Elevating the head of the bed to 90 degrees helps the lungs expand more fully, especially the bases, which often become underinflated after surgery. This reduces the work of breathing and improves ventilation-perfusion matching, leading to quicker improvement in oxygenation for a patient with hypoxemia and pleuritic chest pain. While oxygen therapy and continuous monitoring are important, changing to a high-Fowler position provides an immediate physiologic benefit to breathing and gas exchange, making it the best first intervention in this scenario.
