A nurse is preparing nasopharyngeal suctioning for an adult client. Which of the following techniques should the nurse use?

A) Wait 1 min between suctioning attempts: The nurse should wait 20 to 30 seconds between suctioning attempts, not a full minute. Waiting too long between attempts can cause the patient unnecessary distress. The goal is to allow for oxygenation and recovery of the airway in between suctioning attempts. B) Apply intermittent suction for 30 seconds: Suctioning should be limited to 10 to 15 seconds at a time to prevent hypoxia and damage to the mucous membranes. Applying suction for 30 seconds could lead to complications such as hypoxia, mucosal trauma, and increased risk of infection. C) Insert the catheter 10 cm (4 in.): This is the correct technique. For an adult client, the catheter should be inserted 10 cm (4 inches) into the airway. Inserting the catheter too far can cause trauma to the airway, while inserting it too shallow may not effectively clear secretions. D) Apply suction while inserting the catheter: Suction should not be applied while inserting the catheter. Suctioning should only be applied while withdrawing the catheter, not while inserting it, to prevent mucosal trauma and to ensure effective clearance of secretions. Suctioning during insertion could damage the airway and increase discomfort for the client.
