Answer:d. Loss of cough reflex results in decreased ability to remove secretions effectively.
Explanation:
The nerves of the nervous system (autonomic) are numb during the lung transplant process. This results in the denervation of the lungs. This will result in the loss of the cough reflex. As a result the patient is not able to secrete clear secretion. The patient get exposed to high risk of infection. This can also lead to acute respiratory distress syndrome.
