Answer to Question 1

ANS: A
In pressure support only the pressure is controlled, thus of all the classic modes of ventilation the mode that is least likely if set properly to cause asynchrony is pressure support. However, as well documented in the literature, proportional assist ventilation (PAV) and neurally adjusted ventila-tory assist (NAVA) are the modes of ventilation that are least likely to cause asynchrony because they do not exert any control over the patient.

Answer to Question 2

ANS: C
