Answer to Question 1

mucociliary transport system
In the normal lung, the mucociliary transport system clears the airways of excessive mucus and inhaled particles. This system lines the internal lumen of the entire tracheobronchial tree and consists of a thin layer of mucus that is constantly being propelled toward the larynx by cells that have hairlike projections called cilia .

Answer to Question 2

C
Allow the bag to empty gradually over 30 to 45 minutes. Gradual emptying of tube feeding by gravity from the feeding bag reduces the risk for abdominal discomfort, vomiting, or diarrhea induced by bolus or too-rapid infusion of tube feedings. Cold formula causes gastric cramping. Place the patient in high-Fowler's position, or elevate the head of the bed at least 30 degrees to prevent aspiration. Do not add food coloring or dye to formula to assist in detecting aspiration, presumably by staining tracheobronchial secretions. This is associated with increased risk for contamination and may cause patient deaths.
