What intervention is appropriate when managing a patient experiencing respiratory compromise?

Administering supplemental oxygen is an appropriate intervention for managing a patient experiencing respiratory compromise because it directly addresses the underlying issue of inadequate oxygenation. When a patient shows signs of respiratory distress or failure, they are not getting enough oxygen into their bloodstream, which can lead to hypoxia and adversely affect vital organs. Providing supplemental oxygen increases the amount of oxygen available to the lungs and can significantly improve the patient's oxygen saturation levels and overall respiratory function.

In contrast, other interventions listed, such as performing compressions, initiating defibrillation, or applying a tourniquet, are not suitable for respiratory compromise. Compressions are part of cardiopulmonary resuscitation (CPR) and are crucial during cardiac arrest, while defibrillation is specifically indicated for certain types of cardiac arrhythmias. Applying a tourniquet is relevant to controlling severe bleeding rather than addressing respiratory issues. Hence, supplemental oxygen is the correct choice in this scenario, as it specifically targets the respiratory insufficiency present in the patient.
