The physician has ordered continuously positive airway pressure (CPAP) with the delivery of oxygenation. The nurse recognizes that the benefit of CPAP is that it allows:
A) A higher percentage of oxygen to be used
B) A lower percentage of oxygen to be used
C) For humidification of oxygen
D) For the elimination of bacterial growth in oxygen delivery systems
Ans: B
Feedback: Prevention of oxygen toxicity is achieved by using oxygen only as prescribed. Often, positive end-expiratory pressure (PEEP) or continuous positive airway pressure (CPAP) is used with oxygen therapy to reverse or prevent microatelectasis, thus allowing a lower percentage of oxygen to be used. Oxygen is moistened by passing through a humidification system. Changing the tubing on the oxygen therapy equipment is the best technique for controlling bacterial growth.
