A nurse is preparing to suction a patient with a tracheostomy who has audible secretions and a falling oxygen saturation. Which action should occur immediately before inserting the catheter?
Correct answer: B. Preoxygenate the patient with prescribed oxygen
- A. Apply suction while advancing the catheter
- B. Preoxygenate the patient with prescribed oxygen
- C. Give oral fluids to loosen the secretions
- D. Deflate the cuff and remove the tube
Explanation
Preoxygenation helps reduce the risk of hypoxemia during the brief suctioning procedure. Suction is not applied during insertion because it can injure the mucosa, and removing or deflating the tube is not routine suction preparation.
