Answer to Question 1

ANS: B
The internal receiver of a cochlear implant is sutured in position over the temporal bone behind the ear.

Answer to Question 2

ANS: D
Nitrous oxide can diffuse into cavities and may cause expansion of the middle ear. Nitrous oxide is to be discontinued before placing a graft in a middle ear to minimize pressure that could displace the graft.
