What is the appropriate action when placing a cap on a tracheostomy tube with an inflated cuff?

Choice A rationale Removing the tracheostomy tube is an incorrect and dangerous action. The tracheostomy tube maintains a patent airway. Removing it without proper preparation could lead to airway loss, requiring an emergency re-intubation or a surgical procedure. The cuff must be deflated before capping. Choice B rationale Placing a cap on a tracheostomy tube with an inflated cuff is extremely dangerous. The inflated cuff blocks the passage of air around the tube and into the upper airway. Capping the tube in this state would prevent the patient from breathing, leading to immediate respiratory distress and asphyxiation. Choice C rationale Before capping a tracheostomy tube, the cuff must be deflated. The cuff's purpose is to seal the airway, preventing aspiration and ensuring ventilation. Capping is a step toward decannulation, which requires the patient to breathe through their upper airway, a process only possible when the cuff is deflated. Choice D rationale Placing a cap on a tracheostomy tube with an inflated cuff is an unsafe and potentially lethal action. The inflated cuff completely obstructs the patient's ability to breathe around the tube and through their natural airway. Deflating the cuff is a prerequisite for capping, allowing the patient to breathe through their mouth and nose.
