  d. 80 L/min

Question 2

A patient receiving pressure controlledcontinuou s mandatory ventilation (PC-CMV) has initial arterial blood gas (ABG) findings as follows: PaO2 of 101 mm Hg, partial pressure of carbon di-oxide in the arteries (PaCO2) of 60 mm Hg, and pH of 7.30.
 
  The respiratory therapist should:
  a. increase minute ventilation to this patient.
  b. decrease pressure setting.
  c. change the ventilation mode.

Answer to Question 1

ANS: D
An initial flow of 80 L/min typically is suggested when setting up a patient on volume ventilation with a constant flow. The pressure-time scalar should be evaluated for its appearance to ensure an appropriate flow rate.

Answer to Question 2

ANS: A
The kidneys normally can compensate for respiratory acidosis within 18-36 hours. Obviously, it is desirable for the problem to be corrected by increasing alveolar ventilation rather than waiting for renal compensation. Increasing ventilation can be accomplished by increasing the VT or manda-tory rate.
