A nurse is caring for a group of clients on an adult medical-surgical unit. Which of the following clients should the nurse identify as having the highest risk for aspiration?

Choice A rationale A chest tube is placed to drain air or fluid from the pleural space, often due to conditions like pneumothorax or hemothorax. While severe underlying pulmonary issues could increase aspiration risk, the presence of the chest tube itself does not directly impair the pharyngeal or esophageal phases of swallowing or depress the gag reflex as significantly as a tube traversing the upper airway. Choice B rationale An ileostomy is a surgical creation of an opening from the ileum to the outside of the body, diverting stool. This procedure involves the lower gastrointestinal tract and does not directly interfere with the epiglottis function, swallowing mechanisms, or the patency of the lower esophageal sphincter, thus posing a negligible aspiration risk. Choice C rationale An NG (nasogastric) tube is placed through the nose, pharynx, and esophagus into the stomach. The presence of this foreign object can compromise the competence of the lower esophageal sphincter and mechanically impair the glottic closure reflex, significantly increasing the likelihood of gastric contents refluxing into the pharynx and then being aspirated into the lungs. Choice D rationale A colostomy is a surgical opening from the colon to the body's surface, diverting fecal matter. Similar to an ileostomy, this is a modification of the lower gastrointestinal tract and does not impair the coordination of the pharyngeal muscles, the protective function of the epiglottis, or the esophageal motility necessary to prevent aspiration.
