4. The nurse is reviewing the structures of the ear. Which of these statements
concerning the eustachian tube is true?
a. The eustachian tube is responsible for the production of cerumen.
b. It remains open except when swallowing or yawning.
c. The eustachian tube allows passage of air between the middle and outer
ear.
d. It helps equalize air pressure on both sides of the tympanic membrane.
ANS: D
The eustachian tube allows an equalization of air pressure on each side of the
tympanic membrane so that the membrane does not rupture during, for example,
altitude changes in an airplane. The tube is normally closed, but it opens with
swallowing or yawning.
