Administering oxygen is the priority nursing action for a patient in acute respiratory distress because it directly addresses the critical issue of impaired gas exchange and oxygenation. In situations where a patient is experiencing respiratory distress, their oxygen saturation levels may drop, leading to potential hypoxia, which can result in serious complications if not promptly managed.

By providing supplemental oxygen, the nurse can help maintain adequate oxygen levels in the blood, which is essential for cellular metabolism and overall organ function. Ensuring the patient has sufficient oxygen availability can alleviate symptoms of distress and provide the immediate support needed while further assessments and interventions are carried out.

Other interventions, such as performing chest physiotherapy, administering antihistamines, or reassuring the patient, may have roles in management but are not immediate priorities in the context of acute respiratory distress. These actions can be indicated depending on the underlying cause of the respiratory distress, but they do not directly address the urgent need for oxygenation, making them secondary to the priority of oxygen administration.
