Prep
1. Describe the significance of increased central apneas in non-REM sleep for a
patient with a history of spinal fusion and pain management.
Increased central apneas in non-REM sleep indicate potential
respiratory instability, which can be exacerbated by medications
used for pain management.
Increased central apneas in non-REM sleep are a sign of effective pain
management and spinal recovery.
Increased central apneas in non-REM sleep are unrelated to
medication effects and indicate normal sleep patterns.
Increased central apneas in non-REM sleep suggest improved sleep
quality and reduced pain perception.
2. A nurse mentor is teaching nursing students about continuous positive airway
pressure (CPAP). Which statement from a nursing student indicates a need for
further teaching?
"CPAP prevents collapse of upper airway through the use of pressure
delivered through nasal oral or oronasal mask."
"CPAP is the treatment of choice for obstructive sleep apnea (OSA)."
"CPAP treatment remains unaffected by weight gain and use of
sedatives before bedtime."
"CPAP delivers a continuous stream of positive pressure, keeping the
airway open providing an unobstructed airway."
3. Asystole is scored when there is a cardiac pause greater than:
5 seconds
, 30 seconds
10 seconds
3 seconds
4. Describe what Sleep Efficiency percentage indicates about a person's sleep
quality.
Sleep Efficiency percentage indicates the ratio of time spent asleep
to the total time spent in bed.
Sleep Efficiency percentage measures the total hours of sleep per
night.
Sleep Efficiency percentage shows the average duration of sleep
cycles.
Sleep Efficiency percentage reflects the number of awakenings during
the night.
5. What is the standard calibration voltage used in an EOG recording?
25
75
50
100
6. If a patient experiences asystole for 25 seconds, what immediate action
should be taken?
Monitor the patient for further symptoms
Administer medication to stabilize heart rhythm
Wait for the patient to regain consciousness
, Initiate cardiopulmonary resuscitation (CPR)
7. The nurse is performing an initial interview with an older adult whose family is
concerned that she is demonstrating early signs of dementia. Which
intervention best demonstrates that the nurse understands how to effectively
communicate with a cognitively impaired individual?
the older adult is provided with a list of written questions that will be
addressed
the interview is postponed until a family member can be present
the nurse restates the question if the older adult appears to hesitate
when answering
the nurse is careful to avoid medical terminology during the interview
8. Why is it important to increase the CPAP pressure if a patient experiences
arousals and soft snoring despite stable oxygen saturation?
Increasing the CPAP pressure may help eliminate arousals and
improve sleep quality.
Soft snoring is not a concern during CPAP titration.
Arousals are irrelevant to the effectiveness of CPAP therapy.
Stable oxygen saturation indicates no need for change in pressure.
9. If a patient reports increased anxiety after starting an SSRI, what might be a
potential explanation based on the drug's mechanism of action?
The patient may be experiencing an initial increase in serotonin
levels before the therapeutic effects are realized.
The patient is likely experiencing a placebo effect.
The SSRI is ineffective and should be discontinued immediately.
, The SSRI is causing a decrease in serotonin levels.
10. If a sleep technician observes significant differences in a patient's sleep data
between the first and second nights of a PSG, how should they interpret
these findings?
They should disregard the first night data as irrelevant.
They should consider the first-night effect as a possible
explanation for the differences observed.
They should assume the patient has narcolepsy based on the
differences.
They should conclude that the patient has severe apnea.
11. If a patient with severe OSA continues to experience anxiety about using
CPAP despite education and mask fit adjustments, what intervention might be
most effective to help them adapt?
Cognitive-behavioral therapy to manage anxiety
Switching to a different type of CPAP machine
Providing additional education on OSA
Increasing the pressure settings on the CPAP
12. What is the criterion for ending a nap during a Multiple Wakefulness Test
(MWT)?
after three consecutive epochs of stage N1 sleep
15 mins after sleep onset
after 15 minutes of wakefulness
at the beginning of stage R sleep
