Based on clinical data, which of the following therapeutic interventions would be most beneficial for COPD patients who develop respiratory failure after extubation?
A. NPPV
B. spontaneous breathing trial
C. O2 therapy with a non-rebreather mask
D. reintubation and invasive positive-pressure ventilation
Q. 2 What is the role of NPPV in cystic fibrosis patients?
A. NPPV has no role in the treatment of cystic fibrosis.
B. It reduces the need for intubation when these patients have pneumonia.
C. NPPV is used in lung transplantation candidates who deteriorate before surgery.
D. NPPV facilitates the removal of tracheobronchial secretions in these patients.
Q. 3 A patient who enters the emergency department has an exacerbation of COPD complicated by pneumonia. The patient is hemodynamically stable, demonstrates a strong cough, and has ABG data consistent with respiratory failure. Which of the following therapeutic interventions would be appropriate at this time?
A. endotracheal intubation and a T-piece
B. endotracheal intubation and invasive positive-pressure ventilation
C. negative pressure ventilation
D. noninvasive positive-pressure ventilation
Q. 4 Which of the following therapeutic modalities would be useful for a COPD patient who has failed numerous spontaneous breathing trials because of respiratory muscle weakness, and is still intubated and receiving invasive positive-pressure ventilation?
A. negative pressure ventilation
B. noninvasive positive-pressure ventilation
C. sedation and controlled mechanical ventilation
D. pressure support ventilation
Q. 5 A patient with congestive heart failure has severe hypoxemia and dyspnea while using a non-rebreather mask.

A. III onlyB. I, II only
C. I, IV only
D. I, II, IV only
Q. 6 What is the role of postextubation NPPV for patients with COPD exacerbations who are intubated because they were not initially candidates for NPPV? I. earlier extubation to NPPV II. reduced incidence of nosocomial infection III. decreased length of stay in hospital IV. shortened duration of positive-pressure mechanical ventilation
A. I. only
