When performing suctioning for a client with a tracheostomy, which action should the nurse include?

Choice A reason: Applying a water-soluble lubricant to the catheter is not recommended during tracheostomy suctioning as it may introduce contaminants. Choice B reason: Instilling sodium chloride before suctioning is not a standard practice and can lead to complications such as edema. Choice C reason: Wearing protective goggles is important to protect the nurse from potential splashes of bodily fluids during the suctioning process. Choice D reason: Instructing the client to cough as the suction tip is removed is not recommended as it can cause discomfort and potential harm to the tracheal lining.
