The nurse is setting up the environment for tracheal suction on a newly postoperative tracheostomy patient. Which action(s) should the nurse perform? (Select 4 correct answers)

A. Perform suction with sterile supplies: Sterile technique is essential when suctioning a tracheostomy to prevent introducing pathogens into the lower airway. Sterile supplies and gloves help reduce the risk of infection in this direct airway access point. B. Auscultate lungs for retained secretions: Before suctioning, the nurse should assess for signs that suctioning is needed, such as abnormal breath sounds (e.g., crackles, rhonchi) that indicate secretion buildup in the airways. C. Don clean gloves and lift out catheter and connect to suction: Clean gloves are insufficient for the suctioning procedure. This is an invasive technique involving direct access to the lower airway, requiring sterile gloves and equipment to prevent infection. D. Wash hands and open sterile suction kit: Hand hygiene is a fundamental part of infection control. Opening the sterile suction kit properly maintains the sterility of equipment needed for the procedure. E. Inform the patient about the procedure: Providing a brief explanation prepares the patient, reduces anxiety, and promotes cooperation. Even if the patient is nonverbal, communication is part of professional and ethical nursing care.
