A nurse is assisting with teaching a class about sleep disorders. The nurse should include that which of the following conditions can cause central sleep apnea (CSA)?

Enlarged tonsils

Obesity

Opioid overdose

Deviated septum

Answer and Explanation

The Correct Answer is C

Choice A reason : Enlarged tonsils can contribute to obstructive sleep apnea by blocking the airway, but they do not cause central sleep apnea, which is related to the brain's control of breathing.

Choice B reason : Obesity is a risk factor for obstructive sleep apnea due to the physical obstruction of the airway, not central sleep apnea, which involves a failure of the brain's signaling to the muscles that control breathing.

Choice C reason : Opioid overdose can depress the central nervous system, including the brain's ability to signal for breath, leading to central sleep apnea.

Choice D reason : A deviated septum can cause difficulty breathing through the nose and contribute to obstructive sleep apnea, but it does not cause central sleep apnea.

Correct Answer is D

Explanation

Choice A reason : Have an eye exam every 2 years.For individuals with diabetes, it is recommended to have an eye exam annually, not every two years, due to the high risk of developing diabetic retinopathy and the need for early detection and treatment.

Choice B reason : It is caused by an increase in intraocular pressure.Diabetic retinopathy is not caused by an increase in intraocular pressure; that is more characteristic of glaucoma. Diabetic retinopathy is caused by damage to the blood vessels in the retina due to high blood sugar levels.

Choice C reason : Clouding of the lens is a manifestation of diabetic retinopathy.Clouding of the lens is a manifestation of cataracts, not diabetic retinopathy. Diabetic retinopathy involves changes to the blood vessels in the retina, not the lens of the eye.

Choice D reason : "Seeing spots is a manifestation of diabetic retinopathy.""Seeing spots," or floaters, can indeed be a manifestation of diabetic retinopathy. This occurs when blood vessels in the retina are damaged and leak blood or other fluids, causing these spots to appear in the vision.

A. Drinking caffeinated beverages in the evening B. Emotional stress C. Bright light D. A 20-minute nap during the day

Correct Answer is A

Explanation

Choice A reason : Drinking caffeinated beverages in the evening.Caffeine is a stimulant that can significantly disrupt the sleep-wake cycle. Consuming caffeinated beverages in the evening can lead to difficulty initiating sleep because caffeine blocks the action of adenosine, a chemical that promotes sleep. The effects of caffeine can last several hours, thus affecting the quality and duration of sleep.

Choice B reason : Emotional stress activates the body's stress response, causing the release of hormones like cortisol, which increases alertness and can delay the onset of sleep. Chronic stress can lead to a hyperarousal state, making it difficult to fall asleep and stay asleep.

Choice C reason : Bright light.Exposure to bright light, especially blue light from screens, can interfere with the production of melatonin, the hormone that signals the body to prepare for sleep. This can shift the circadian rhythm and disrupt the sleep-wake cycle, making it harder to fall asleep at the usual time.

Choice D reason : A short nap during the day, typically 20-30 minutes, can be beneficial and usually does not interfere with nighttime sleep. However, longer or later naps can make it more difficult to fall asleep at night.
