After morning care, the nurse prepares for tracheostomy care. Which action will the nurse take? Select all that apply.

A. Tracheostomy care requires a sterile technique to prevent infection, as the trachea is a direct airway into the lungs. A sterile field is essential before cleaning and handling the trach tube. B. Trach ties that are wet or soiled can harbor bacteria, cause skin breakdown, or compromise tube stability. Changing them maintains airway security and hygiene. C. Removing old dressings and secretions prevents infection, keeps the skin clean, and prepares the site for new sterile dressings. D. Suctioning is typically done before tracheostomy care to clear secretions, allowing the nurse to clean the site without obstruction or contamination. Suctioning after care is only done if secretions accumulate again. E. Full-strength hydrogen peroxide is too harsh and can damage tissue. The inner cannula should be cleaned with sterile saline or a diluted, safe solution to remove secretions without causing chemical injury.
