Nadia, Answer is C for sure.
The diagnosis is CF. The primary goals of treatment include thinning the mucus secretions, keeping the airways open, and treating recurrent infections. Thinning the mucus can be achieved with mucolytics such as NAC (mucomyst) this drug splits the disulfide linkages between these mucoproteins, resulting in a decrease in mucous viscosity. It is indicated as adjuvant therapy in the treatment of abnormal viscid or inspissated mucus secretions in CF, chronic lung disease Post-traumatid chest complications, and atelectasis secondary to mucus obstruction. Inhaled bronchodilators are used to open the airways. Furthermore, prednisone has been shown to increase pulmonary function and increase body weight. The definitive treatment is lung transplantation.
I hope this explantion helps.
