TMC NBRC Test Bank with Complete Solutions Disadvantages of noninvasive ventilation include which one of the following? A. costs more than invasive ventilation B. requires heavy patient sedation C. limits direct access to lower airway D. increases the likelihood of VAP ANSWER Disadvantages of noninvasive ventilation (NPPV) include the following: it can only be used in cooperative patients; it does not provide direct airway access (thus increasing the risk of secretion retention), and more therapist time is needed during the initial period of use. On the other hand NPPV may help decrease the incidence of VAP and typically costs less than invasive ventilation. The correct answer is: limits direct access to lower airway On a patient receiving volume control AC ventilation, you observe a flow-volume with a sawtooth pattern on exhalation. Which of the following actions would you consider most appropriate? A. recommend administering a bronchodilator B. assess the patient's need for suctioning C. measure the endotracheal tube cuff pressure D. switch to pressure control ventilation ANSWER The flow-volume loop reveals irregular sawtooth- like oscillations, primarily in the expiratory portion of the loop. This indicates either 1) accumulation of airway secretions in the trachea/large airways (requiring suctioning), or 2) condensate partially blocking the expiratory limb of the ventilator circuit proximal to the expiratory flow
