DETAILED VERIFIED ANSWERS EXAM QUESTIONS WILL

1. A nurse is educating a patient about the importance of sleep for
optimal health. Which statement by the patient indicates an
understanding of the physiological benefits of NREM (non-rapid eye
movement) sleep?
A. "This is when I do most of my vivid dreaming."
B. "This stage helps my body repair tissues and strengthen my immune
system."
C. "My brain activity during this stage is almost the same as when I am
awake."
D. "This stage is characterized by rapid eye movements and muscle
paralysis."
Answer: B. NREM sleep, particularly stages 3 and 4 (slow-wave sleep), is
crucial for physiological restoration, including tissue repair, immune
function strengthening, and the release of growth hormone.
Explanation: Option A and D describe REM sleep. Option C describes
brain activity in REM sleep, which is highly active, not NREM.

2. A patient reports difficulty falling asleep and staying asleep multiple
times per week for the last 2 months due to work stress. This
presentation is most consistent with which type of insomnia?
A. Transient insomnia
B. Short-term insomnia
C. Chronic insomnia disorder
D. Idiopathic insomnia
Answer: B. Short-term insomnia is defined by symptoms occurring for
less than 3 months and is often associated with an identifiable stressor.
Explanation: Transient insomnia lasts less than a week (Option A).
Chronic insomnia disorder persists for 3 months or longer and occurs at
least 3 times per week (Option C). Idiopathic insomnia is a lifelong
condition with no identifiable precipitant (Option D).
3. The nurse is teaching a community group about sleep hygiene. Which
recommendation aligns with establishing a consistent bedtime routine?
A. "Engage in high-intensity exercise 30 minutes before bed."
B. "Watch television in bed to help your mind unwind."
C. "Take a warm bath and read a physical book 1 hour before sleep."
D. "Consume a large, high-protein meal right before lying down."
Answer: C. A warm bath raises body temperature, and the subsequent
drop can promote sleep onset; reading a physical book avoids blue light
exposure.

Explanation: Vigorous exercise late in the evening is stimulating (Option
A). The blue light from screens suppresses melatonin (Option B). Large
meals before bed can cause indigestion and disrupt sleep (Option D).
4. Which neurotransmitter, produced by the pineal gland, is most
responsible for regulating the circadian sleep-wake cycle?
A. Serotonin
B. Dopamine
C. Melatonin
D. Gamma-aminobutyric acid (GABA)
Answer: C. Melatonin is the primary hormone that regulates circadian
rhythms, with its secretion increasing in darkness to promote sleep.
Explanation: Serotonin is a precursor to melatonin and regulates mood
(Option A). Dopamine is involved in wakefulness and alertness (Option
B). GABA is the primary inhibitory neurotransmitter that decreases
neuronal excitability to induce sleep (Option D).
5. A patient newly diagnosed with obstructive sleep apnea (OSA) asks
the nurse what causes this condition. Which pathophysiological
explanation is most accurate?
A. "The brain intermittently fails to send signals to the respiratory
muscles."
B. "The soft tissues of the upper airway collapse and block airflow
during sleep."
C. "There is a narrowing and stiffening of the bronchioles in the lungs."
, 4|Page
D. "An overproduction of cerebrospinal fluid increases intracranial
pressure at night."
Answer: B. Obstructive sleep apnea is a mechanical problem caused by
the relaxation and collapse of the pharyngeal soft tissues (tongue and
soft palate) during sleep.
Explanation: Option A describes central sleep apnea. Option C describes
asthma or COPD. Option D is not related to OSA.
6. The primary treatment for moderate to severe obstructive sleep
apnea involves positive airway pressure. What is the therapeutic
mechanism of CPAP (Continuous Positive Airway Pressure)?
A. It delivers supplemental oxygen under high pressure.
B. It acts as a pneumatic splint to keep the airway open.
C. It stimulates the phrenic nerve to contract the diaphragm.
D. It creates negative pressure in the chest to assist inhalation.
Answer: B. CPAP delivers a constant, fixed stream of pressurized air
that prevents airway collapse by splinting the pharynx open.
Explanation: CPAP delivers room air, not exclusively oxygen (Option A).
Phrenic nerve stimulation is an intervention for central apnea (Option
C). Negative pressure ventilation is not a standard OSA treatment
(Option D).
7. A nurse is caring for a patient who has been using a benzodiazepine
for sleep for several years. The patient asks about discontinuing the
medication. What is the most critical teaching point regarding
benzodiazepine withdrawal?
