A nurse is providing discharge teaching to the partner of a client who has a tracheostomy. Which of the following information should the nurse include in the teaching?

The correct answer is B: How to change the tracheostomy dressing using clean technique. This is important to prevent infection and promote healing. First, wash hands and gather supplies. Remove the old dressing, clean the stoma site with sterile saline, and apply a new sterile dressing. The other choices are incorrect: A is incorrect because securing the tracheostomy tube should be done at the side, not the back, to prevent pressure on the trachea. C is incorrect as operating the suction machine is usually done by healthcare professionals. D is incorrect because changing the non-disposable tube daily is unnecessary and can increase the risk of infection.
