A nurse is providing discharge teaching for the family of a client who had a tracheostomy inserted 2 months ago. Which of the following instructions should the nurse include?

Rationale: A. "Use the clean technique when suctioning.": For a well-established tracheostomy (typically after 1 month), clean technique is acceptable for suctioning at home. This reduces infection risk while allowing practical self-care or family-provided care in a non-sterile environment. B. "Clean the stoma site with full-strength hydrogen peroxide.": Full-strength hydrogen peroxide is too harsh and can damage healthy tissue. A diluted solution or normal saline is safer for routine stoma care to avoid irritation and promote healing. C. "Decrease the humidity level in your home.": Adequate humidity is essential for clients with tracheostomies to keep secretions thin and prevent airway blockage. Low humidity can dry the airway and increase the risk of mucus plugs. D. "Remove soiled tracheostomy ties before replacing them.": Tracheostomy ties should be replaced one side at a time to prevent accidental decannulation. Removing both sides at once leaves the tracheostomy tube unsecured and poses a serious safety risk.
