Answer to Question 1

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: As respiratory failure stabilizes and begins to reverse, clinical attention should shift to the ventilator withdrawal process. In these patients, continued ventilator dependency is caused by two fundamental problems: (1) disease-imposed problems, such as mechanical/gas exchange issues that continue to require positive-pressure ventilation, and (2) clinician-imposed issues, including either clinician delay in recognizing the ability of a patient to have the ventilator discontinued or inappropriate ventilator settings that overload respiratory muscles, preventing recovery.

Answer to Question 2

ANS: A
A. Correct response: The task force recommends that no single measurement or indicator be used to judge the success or failure of an SBT. Rather, an integrated assessment of the respiratory pattern, hemodynamic status, gas exchange, and patient comfort should be used.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
