Transfusion-related acute lung injury (TRALI) is most directly associated with which finding?

Explanation:
Transfusion-related acute lung injury presents as sudden breathing difficulty and low oxygen levels after a transfusion, due to noncardiogenic pulmonary edema from increased capillary leak in the lungs. The edema occurs without heart failure or fluid overload, so the chest imaging shows bilateral pulmonary edema even though blood pressure might not be elevated. This edema is the defining finding of TRALI. Allergic rash, hypertension, and abdominal pain aren’t characteristic features of TRALI, making pulmonary edema the most direct association.
