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

A. This is incorrect because suction should not be applied during the insertion of the catheter. Suctioning should only be applied while withdrawing the catheter to avoid causing trauma to the mucosa. B. Suctioning should generally be performed for no longer than 10 seconds at a time to minimize the risk of complications such as hypoxia. C. This response is correct because waiting approximately 1 minute between suctioning attempts allows the client time to recover and reoxygenate. This interval helps prevent hypoxia and mucosal damage, which are important considerations during the suctioning process. D. In adults insert catheter approximately 16 cm (6.5 inches); in older children, 8– 12 cm (3–5 inches); in infants and young children, 4–7.5 cm (1.5–3 inches). Rule of thumb is to insert catheter distance from tip of nose (or mouth) to angle of mandible.
