发帖数: 73 | 5 Because certain nerve connections to the lungs are cut during the procedure,
transplant recipients cannot feel the urge to cough or feel when their new
lungs are becoming congested. They must therefore make conscious efforts to
take deep breaths and cough in order to clear secretions from the lungs.

发帖数: 445 | 6 it says"one month later", also it already tells you that both the FEV1 &
stress TEST ARE NORMAL, so the pulmonary function should be OK.
Besides, This patient w/ primary pulmonary hypertension undergoes lung transplant to improve the perfusion, which has nothing to do with her pulmonary function itself.
I 'm with Answer B.
