A nurse is preparing to perform suctioning for an infant who has a partial mucus occlusion of her tracheostomy tube. Which of the following actions should the nurse plan to take?

A. Selecting a catheter that fits snugly is important for proper suctioning, but it is more important to ensure the catheter is the correct size for the infant’s tracheostomy tube and airway. B. Instilling saline prior to suctioning is generally not recommended unless specified by the healthcare provider, as it can increase the risk of aspiration and discomfort. C. Suctioning should be done in short 3 to 4 second increments to avoid injury to the airway and to minimize the infant’s distress. Prolonged suctioning can cause hypoxia and trauma to the mucosa. D. Suctioning for infants with tracheostomies requires sterile technique to prevent infection, not clean technique.
