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: With HFJV, the therapist has control over the respiratory rate, inspiratory time, jet drive pressure, and expiratory pressure. Ultimately, however, the delivered jet Vt depends on a number of factors, including (1) the drive pressure, (2) injector diameter, (3) inspiratory time, (4) ETT size, (5) presence of an entrainment gas, and (6) the development of auto-PEEP.

Answer to Question 2

ANS: D
A. Incorrect response; See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: According to the author, HFV is defined as a respiratory rate greater than 100 breaths/min for adults, and greater than 300 breaths/min for neonatal and pediatric patients.
