Which action directly improves tissue oxygen delivery in a patient with respiratory distress?

Explanation:
Directly increasing the amount of oxygen carried to tissues is achieved by administering supplemental oxygen as ordered. Raising the fraction of inspired oxygen elevates arterial oxygen tension (PaO2) and improves oxyhemoglobin saturation, boosting the oxygen content of blood that reaches tissues and supporting cellular metabolism during respiratory distress. While assessing oxygenation, monitoring vital signs, and escalating care are important parts of ongoing management, they do not by themselves raise the actual amount of oxygen delivered to tissues in the moment—that direct improvement comes from giving the prescribed oxygen.
