A nurse is assessing equipment needs in order to perform tracheostomy suctioning on a client. Which of the following pieces of equipment should the nurse gather for the procedure?

Rationale: A. Pulse oximeter: A pulse oximeter is useful for monitoring oxygen saturation during suctioning, but it is not required for the procedure itself. The primary equipment needed is related to suctioning and maintaining airway patency. B. Sterile water: Sterile water is essential for tracheostomy suctioning to keep the suction catheter sterile and to irrigate the catheter as needed. It helps to prevent infection and maintain hygiene during the procedure. C. Nasal cannula: A nasal cannula is used for oxygen delivery, but it is not required for the suctioning procedure itself. Suctioning may be performed independently of oxygen therapy, although oxygen may be administered after suctioning if needed. D. Yankauer catheter: A Yankauer catheter is used for oral suctioning, not for tracheostomy suctioning. For tracheostomy suctioning, a specific tracheal suction catheter is required to fit the airway.
