  3. Dead space-to-tidal volume ratio (VD/VT)
  4. Maximum inspiratory pressure (MIP)
  a. 1 and 3 only
  b. 2 and 4 only
  c. 3 and 4 only
  d. 1, 2, and 4 only

Question 2

A reversible impairment in the response of an overloaded muscle to neural stimulation best de-scribes which of the following?
 
  a. Central respiratory muscle fatigue
  b. Transmission respiratory muscle fatigue
  c. Contractile respiratory muscle fatigue
  d. Chronic respiratory muscle fatigue

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.
