Answer to Question 1

ANS: B
Advantages of assist-control volume ventilation include the assurance that a minimum safe level of ventilation is achieved, yet the patient can still set his or her own breathing rate. In the event of sedation or apnea, a minimum safe level of ventilation is guaranteed by the selection of an ap-propriate backup rate, usually approximately 4 to 6 breaths/min less than the patient's assist rate but not less than the rate necessary to provide a minimum safe level of ventilation (e.g., a backup rate of at least 12 to 14 breaths/min). Because assist-control ventilation usually provides full ven-tilatory support, it may result in less WOB. In volume control ventilation, pressure is variable and not limited.

Answer to Question 2

ANS: B
Most clinicians consider HFOV and conventional ventilation the best ways to manage ARDS who require mechanical ventilation.
