Postoperative atelectasis can be prevented with which of the following maneuvers?

Question

Quizplus · Accepted Answer

Collapse of alveoli can be prevented with maneuvers that keep them open, such as taking deep breaths, coughing, using incentive spirometry, or positive pressure ventilation (for example, in mechanical ventilation using positive end-expiratory pressure [PEEP]). Placing a cotton-tipped swab in a patient's nostril is a form of noxious stimulation used to rouse a comatose or obtunded patient. It has no direct effect on alveolar ventilation. Deep suctioning of the lower airways may sometimes worsen or cause atelectasis.
