Answer to Question 1

Ans:
A

Feedback:

Brain activity during sleep is lessened but is more synchronous than during waking. The brain is not more active during sleep, and alpha and beta rhythms are not associated with sleep. The brain is never truly inactive during sleep.

Answer to Question 2

Ans:
C

Feedback:

Because the external auditory canal is innervated by the auricular branch of the vagus nerve, coughing or even cardiac deceleration can result from stimulation of the canal by cerumen impactions or removal attempts. Since this just involves irrigation using a bulb syringe and warm tap water, bleeding should not occur. Pain may occur but is not a critical complication. Since the fluid is going into the ear canal, there should be no fluid entering the respiratory system.
