A male patient (74-kg IBW) is being ventilated with PC-CMV, f = 12/min, pt rate of 8, PIP = 20 cm H2O, TI = 1.5 seconds; the resulting flow-time scalar is shown below. The patient’s measured VT is 435 mL. ABG results on these settings are: pH 7.32, PaCO2 54 mm Hg, HCO3- 25 mEq/L. The most appropriate action to take is which of the following?

It is appropriate to use an oral airway on which of the following pts?

All of the following are goals of noninvasive ventilation (NIV) in the acute care setting except:

A 46-year-old male patient is 2 days post-op for surgery to repair and aortic aneurysm. He is currently receiving mechanical ventilation. Auscultation of the anterior and posterior chest reveals bilateral late inspiratory crackles. Percussion is dull in both lower lobes. A STAT radiograph reveals bibasilar infiltrates. The most likely cause of this patient’s clinical presentation is which of the following?

Indications for artificial airways are which of the following? I. airway is compromised II. bypass defense mechanism III. facilitate suctioning IV. patient’s airway can no longer perform proper functions

While monitoring a pt being weaned through a T tube protocol, signs indicating that mechanical ventilation should be restored include which of the following? I. development of cardiac arrhythmias II. asynchronous or paradoxical breathing III. development of severe hypotension IV. mild rise in respiratory rate

Which of the following are sedatives? I. diazepam II. midazolam III. fentanyl IV. propofol

You come upon a pt in PRVC and you notice that the pt is not getting their VT that is set, you have been watching for awhile and notice that the high pressure alarm is not sounding despite the PIP being at 40 cmH20, which of the following is true for this pt?
