A commenter gave his : I think the right answer might be E. There are studies out there about aspiration prevention by jejunostomy tube placement. At the same time, aspiration risk is increased with poorly fitted dentures or missing teeth. This patient has false teeth, which by itself do not predispose to aspiration. I think A might be a distractor.

At the same time, aspiration risk is increased with poorly fitted dentures or missing teeth. This patient has false teeth, which by itself do not predispose to aspiration.
