The requirement for lung donors as outlined by OPTN policy emphasizes the importance of specific diagnostic evaluations to ensure the viability and suitability of the lungs for transplantation. The inclusion of a sputum gram stain, FiO2 challenge, and chest x-ray in the correct choice reflects the comprehensive assessment that is necessary.

A sputum gram stain is crucial for identifying potential infectious organisms and assessing the respiratory status of the donor, which directly impacts transplant success. The FiO2 challenge evaluates the oxygenation capacity of the lungs under stress, helping to determine whether the lungs can function adequately post-transplant. A chest x-ray is a standard imaging study that helps in identifying any structural abnormalities or fluid that could contraindicate lung donation.

These tests collectively support the decision-making process regarding donor lung acceptance and are integral to minimizing postoperative complications for the recipient. This approach aligns with the strategies to maximize transplantation outcomes by carefully evaluating donor lung conditions before proceeding with transplantation.
