What is a problem associated with lowering the inspiratory flow when attempting to overcome obstructive inhomogeneities in a patient's lungs during mechanical ventilation?
 
  A. an increased tidal volume
  B. a shorter expiratory time
  C. an increased peak inspiratory pressure
  D. a different flow-time scalar

Question 2

What is a major concern when delivering a positive-pressure breath to the lungs of a patient who has distribution inhomogeneities?
 
  A. overdistention of healthy lung units
  B. overdistention of apical alveoli
  C. underaeration of basal alveoli
  D. maldistribution of pulmonary perfusion

Answer to Question 1

ANS: B

Answer to Question 2

ANS: A
A. Correct response: Distribution in homogeneities is a major factor in creating regional overdistention of normal alveoli during a positive-pressure breath, which can cause overinflation of these alveoli. Overinflation can cause barotraumas or volutrauma.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
