  A. I, III only
  B. II, IV only

  D. II, III, IV only

Question 2

Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: For spontaneously breathing patients, heliox is administered by face mask with a reservoir bag. A Y-piece is attached to the mask to enable concurrent delivery of aerosolized medications. Sufficient flow to maintain the reservoir bag inflated is required. The flow is often maintained at 12 to 15 L/minute. The patient consumes approximately three to six cylinders per day.
D. Incorrect response: See explanation C.

Answer to Question 2

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Darquenne and Prisk used a radionuclide approach to compare upper respiratory tract deposition with heliox versus air and concluded that heliox might reduce deposition in the upper respiratory tract and increase deposition in the distal airways and alveoli.
D. Incorrect response: See explanation C.
