Which of the following best describes the difference between V/Q mismatch and shunt when supplemental oxygen is administered?    

A 75-year-old male with COPD is admitted with acute bronchitis breathing at a rate of 32 bpm.  Room air blood gas results show a pH 7.50, PaCO2 46 mm Hg, PaO2 45 mm Hg, HCO3ˉ 36 mEq/L.  Which of the following best describe this patient’s condition?    

In acute hypercapnic respiratory failure (Type II), what does the pH do?  Drops about 0.08 units for every 10 mm Hg rise in PaCO2   Rises about 0.08 units for every 10 mm Hg rise in PaCO2  Drops about 0.03 units for every 10 mm Hg rise in PaCO2  Rises about 0.03 units for every 10 mm Hg rise in PaCO2

Which of the following measures taken on adult patients indicate unacceptably high ventilatory demands or work of breathing?  VD/VT of .35  MIP of -80 cm H2O  Minute ventilation (VE) of 20 L/mins  Breathing rate of 20/min

All of the following strategies can help reduce auto-PEEP in mechanically ventilated patients with obstructive lung disease except:1.  Use high inspiratory flows (70 to 100 L/min).2.  Apply extrinsic PEEP.3.  Use low VT values (6 to 8 ml/kg).4.  Use high respiratory rates (>25/min).

Normal respiratory rate & depth of 80-120 breaths/minute
