The nurse knows that which of the following observations of a client during a sleep study would be most likely considered a pathological finding?
 
  A)
  The client experiences periods of apnea of 5 to 15 seconds in duration.
  B)
  The client's intrinsic clock involves a sleep-wake cycle that is consistently 2 hours longer than the actual length of a day.
  C)
  The client's PCO2 level is increased, and his PO2 level decreased during deep sleep.
  D)
  The client spends the majority of his sleeping hours in deep REM sleep.

Question 2

A 4-year-old boy has had otitis media with effusion (OME) for several weeks, and his condition has recently progressed to acute otitis media (AOM).
 
  Which of the following factors could have contributed to his AOM? Select all that apply.
  A)
  Reflux of fluid from the boy's nose into his middle ear
  B)
  A deficiency in immunoglobulin M
  C)
  Accumulation of cerumen in the external acoustic meatus
  D)
  Sensorineural deficits in the auditory control apparatus
  E)
  Exposure to respiratory virus

Answer to Question 1

Ans:
D

Feedback:

While vital, REM sleep does not normally occupy the majority of sleeping hours. The brain is highly active during REM sleep, and it accounts for 20 to 25 of normal sleep. Brief apneic spells are not uncommon, and the circadian rhythm often does not match the 24-hour length of day. It is normal for PCO2 to increase and PO2 to decrease during deep sleep.

Answer to Question 2

Ans:
A, E

Feedback:

Reflux via the eustachian tubes, IgG deficiency, and exposure to RSV have all been implicated in the development of AOM. Cerumen accumulation in the outer ear, deficient IgM, and sensorineural deficits are unlikely to contribute to AOM.
