1. A 52-year-old male enters a sleep study to gather
... [Show More] information about hissleep disturbances. He reports
that his wife will not let him sleep in the bed with her until he stops snoring so loudly. He also reports
feeling tired a lot through the day. When the nurse checks the chart, what is the most likely diagnosis?
• Insomnia - Not Selected
• Correct answer: Obstructive sleep apnea syndrome (OSAS)
• Somnambulism - Not Selected
• Jet-lag syndrome - Not Selected
General Feedback
OSAS generally results from upper airway obstruction recurring during sleep with excessive snoring and
multiple apneic episodes that last 10 seconds or longer. Insomnia is the inability to fall orstay asleep and
may be mild, moderate, or severe. It does not involve snoring. Somnambulism is sleep-walking. Jet-lag
syndrome is a disorder of waking and sleeping and does not involve snoring.
2. For legal purposes, brain death is defined as:
• Correct answer: cessation of entire brain function.
• lack of cortical function - Not Selected
• a consistent vegetative state (VS) - Not Selected
• death of the brainstem - Not Selected
General Feedback
Brain death occurs when there is cessation of function of the entire brain, including the brainstem and
cerebellum. Lack of cortical function or brainstem death is not enough to define brain death. A VS is
complete unawareness of the self orsurrounding environment and complete loss of cognitive function.
3. An infant is diagnosed with congenital hydrocephalus. Which of the following characteristics would
the nurse expect to find?
• Correct answer: Enlarged ventricles
• Decreased cerebrospinal fluid (CSF) production - Not Selected
• Increased resorption of CSF - Not Selected

General Feedback
Congenital hydrocephalus is characterized by enlargement of the cerebral ventricles. Increased, not
decreased, CSF production would lead to hydrocephalus. Decreased resorption of CSF would lead to
hydrocephalus, not increased CSF. An infant with congenital hydrocephalus would have increased head
circumference.
