Answer to Question 1

ANS: D
The most commonly used tests to assess respiratory muscle strength at the bedside are MIP and maximum expiratory pressure (MEP), FVC, and MVV.

Answer to Question 2

ANS: C
Contractile respiratory muscle fatigue is a reversible impairment in the contractile response to a neural impulse in an overloaded muscle.
