Q

Which is MOST LIKELY to occur with the degradation of sevoflurane by absorbent?

A. More degradation occurs at lower temperatures

Q

Which method of confirmation is the BEST way to ensure proper positioning of the bronchial cuff on a double-lumen tube?
A. ETCO2
B. CXR
C. Fiberoptic examination
D. Oxygen concentration

A

C.
