Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: The Compliance Rate Oxygenation and Pressure (CROP) index is an integrated factor that is used to predict the success of weaning from mechanical ventilation. The CROP index is calculated as follows:

= 19.8 ml/breath/min
A CROP index greater than 13 ml/breath/minute indicates an increased likelihood of success for ventilator discontinuation.
D. Incorrect response: See explanation C

Answer to Question 2

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: An esophageal balloon is used to measure esophageal pressure (Pes), which is an estimate of the patient's intrapleural pressure. The Pes is needed to access patient muscle loads. Muscle loads can be expressed as either work or pressure-time products (PTPs) per breath.
D. Incorrect response: See explanation C.
