A nurse is teaching a client about the sleep-wake cycle. The nurse should include that which of the following factors can interfere with the sleep-wake cycle? (Select All that Apply)
A bright light
Drinking caffeinated beverages in the evening
A 20 min nap during the day
Emotional stress
A regular bedtime schedule
Correct Answer : A,B,C,D
A) Bright light: Exposure to bright light, especially in the evening or at night, can interfere with the body's production of melatonin, a hormone that regulates the sleep-wake cycle. Bright light exposure can disrupt circadian rhythms, making it more challenging to fall asleep and stay asleep.
B) Drinking caffeinated beverages in the evening: Caffeine is a stimulant that can interfere with sleep by blocking the effects of adenosine, a neurotransmitter that promotes sleepiness. Consuming caffeinated beverages in the evening can delay the onset of sleep and reduce overall sleep duration.
C) A 20-minute nap during the day: While short naps can be beneficial for some individuals, especially if they are sleep-deprived, napping for too long or too late in the day can disrupt the body's natural sleep-wake cycle. Short naps can be refreshing, but longer or late-day naps can make it harder to fall asleep at night.
D) Emotional stress: Stress and anxiety can trigger the body's "fight or flight" response, leading to increased alertness and difficulty relaxing or falling asleep. Chronic stress can disrupt the sleep-wake cycle, leading to difficulty initiating or maintaining sleep and resulting in poor sleep quality.
E) A regular bedtime schedule: Having a consistent bedtime schedule can actually help regulate the sleep-wake cycle by reinforcing the body's internal clock. Going to bed and waking up at the same time each day, even on weekends, can help improve sleep quality and make it easier to fall asleep and wake up naturally.

Correct Answer is A
Explanation
A) Headache:
Clients with obstructive sleep apnea often experience morning headaches due to the intermittent hypoxia and hypercapnia that occur during episodes of apnea. These headaches are typically described as dull and diffuse and may improve throughout the day.
B) Nausea:
While gastrointestinal symptoms such as nausea can occur in some individuals with sleep apnea, it is not a typical or specific finding associated with this condition. Nausea may result from other causes, such as medication side effects or underlying gastrointestinal issues, rather than directly from obstructive sleep apnea.
C) Hypotension:
Obstructive sleep apnea is more commonly associated with hypertension rather than hypotension. The recurrent episodes of hypoxemia and sympathetic nervous system activation during apneic episodes can lead to systemic hypertension over time.
D) Constipation:
Constipation is not a typical finding associated with obstructive sleep apnea. While sleep apnea may contribute to fatigue and alterations in gastrointestinal motility in some individuals, constipation is not a direct consequence of this sleep disorder.
Correct Answer is B
Explanation
A) Hydrochlorothiazide: Hydrochlorothiazide is a thiazide diuretic that promotes sodium and water excretion, leading to decreased blood volume and decreased potassium excretion. While it can cause hypokalemia due to increased potassium excretion, it does not typically lead to hyperkalemia.
B) Spironolactone: Spironolactone is a potassium-sparing diuretic that inhibits aldosterone, leading to decreased sodium reabsorption and increased potassium retention. This mechanism of action can predispose clients to hyperkalemia due to potassium retention. Additionally, spironolactone can cause hyponatremia by promoting the excretion of sodium and water. Therefore, clients receiving spironolactone are at risk for both hyperkalemia and hyponatremia.
C) Furosemide: Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption in the loop of Henle, promoting sodium, chloride, potassium, and water excretion. While it can cause hypokalemia due to increased potassium excretion, it does not typically lead to hyperkalemia.
D) Metolazone: Metolazone is a thiazide-like diuretic that acts similarly to hydrochlorothiazide by promoting sodium and water excretion. Like hydrochlorothiazide, it can cause hypokalemia due to increased potassium excretion but does not typically lead to hyperkalemia.
