Secretions in the airway of a mechanically ventilated patient ...

[lb_gilbert]

Secretions in the airway of a mechanically ventilated patient could be indicated by a(n):
 
  a. increase in inspiratory capacity.
  b. increase in breathing frequency.
  c. increase in peak inspiratory pressure.
  d. decrease in forced expiratory flow rates.

Question 2

What is the minute volume of a patient if her respiratory rate is 12 breaths/min and her tidal vol-ume is 750 mL?
 
  a. 0.06 L c. 6.25 L
  b. 9.00 L d. 9.00 L

Answer to Question 1

ANS: C
An increase in airway resistance, as with secretions in the airway, will cause an elevation in the peak inspiratory pressure.

Answer to Question 2

ANS: D
Minute volume = tidal volume  respiratory rate.
Minute volume = 0.75 L 12 breaths/min.
Minute volume = 9 L.
