A client with a tracheostomy tube requires suctioning to clear secretions. Which of the following actions should a nurse prioritize to ensure the client's safety and effective airway clearance during the suctioning process?

Suctioning a tracheostomy tube is performed to maintain airway patency by removing accumulated secretions that can obstruct airflow and impair gas exchange. However, the procedure can temporarily reduce oxygen levels and stimulate vagal responses, leading to hypoxia or bradycardia. Therefore, nursing care prioritizes oxygenation, sterile technique, and careful monitoring before, during, and after suctioning. Proper preparation reduces complications and ensures effective airway clearance. Rationale: A. Preoxygenating the client with 100% oxygen before suctioning is the priority intervention because it helps prevent hypoxemia during the procedure. Suctioning temporarily removes oxygen from the airway along with secretions, which can quickly lower oxygen saturation. Preoxygenation increases oxygen reserves, maintaining adequate tissue oxygenation during catheter insertion and suctioning. B. Suctioning continuously while inserting the catheter is incorrect because suction should only be applied while withdrawing the catheter. Continuous suction during insertion can damage tracheal mucosa, cause hypoxia, and remove excessive oxygen from the airway. Proper technique minimizes trauma and preserves oxygenation. C. Monitoring vital signs only after suctioning is incomplete and unsafe because changes in oxygenation and heart rate can occur during the procedure. Continuous or frequent monitoring before, during, and after suctioning is necessary to detect early signs of hypoxia or vagal stimulation. Delayed monitoring may result in missed complications. D. Inserting the suction catheter without sterile gloves is unsafe because it increases the risk of introducing pathogens into the lower respiratory tract. Tracheostomy suctioning requires sterile technique to prevent ventilator-associated or hospital-acquired infections. Maintaining sterility is essential for protecting the airway from contamination and infection.
