A nurse is caring for a client who has a new tracheostomy. Which of the following actions should the nurse take when suctioning the client's tracheostomy?

Rationale: A. Set the suction source at 220 mm Hg: This pressure is excessively high and can damage tracheal mucosa. Recommended suction pressure for an adult tracheostomy is typically 80–120 mm Hg to minimize tissue trauma while effectively clearing secretions. B. Repeat suctioning as needed up to five times: Frequent suction passes increase the risk of hypoxia and mucosal injury. Generally, suctioning should be limited to a maximum of three passes per session, allowing adequate recovery and reoxygenation between attempts. C. Hyperventilate the client with 100% oxygen before suctioning: Preoxygenating helps prevent hypoxemia during suctioning by increasing oxygen reserves. This is a standard safety measure, especially in clients with artificial airways, to maintain oxygenation during the procedure. D. Suction for 20 seconds with each pass: Prolonged suctioning increases the risk of hypoxia, arrhythmias, and airway trauma. Each suction pass should be limited to 10–15 seconds for adults to reduce complications and promote safety.
