MECHANICAL VENTILATION (NCLEX) EXAM 2 QUESTIONS WITH COMPLETE SOLUTIONS \GRADED A+ The peak pressure alarm is sounding on the ventilator of the client with a recent tracheostomy. What intervention should be done first? A. Assess the client's respiratory status B. Decrease the sensitivity of the alarm C. Ensure that the connecting tubing is not kinked D. Suction the client - ANSWER -A The client must always be assessed before attention is turned to equipment. The client with respiratory failure has been intubated and placed on a ventilator and is requiring 100% oxygen delivery to maintain adequateoxygenation. Twenty-four hours later, the nurse notes new-onset crackles and decreased breath sounds, and the most recent ABGs show a PaO2 level of 95 mm Hg. The ventilator is not set to provide positive end-expiratory pressure (PEEP). Why is the nurse concerned? A. The low PaO2 level may result in oxygen toxicity B. The 100% oxygen delivery requirement indicates immediate extubation C. Lung sounds may indicate absorption atelectasis D. The level of oxygen delivery may indicate absorption atelectasis - ANSWER -C High levels of oxygen delivery can result in collapsed alveoli and absorption atelectasis. PEEP can help alveoli remain properly inflated. The medical nurse is
