A nurse is teaching a student about cerebral edema. The student nurse asks, "What type of cerebral edema is associated with a client who has a stroke?" Which of the following is the best response from the nurse?
Vasogenic cerebral edema
Osmotic cerebral edema
Cellular cerebral edema
Interstitial cerebral edema
The Correct Answer is A
Choice A Reason:
Vasogenic cerebral edema is appropriate response. Vasogenic cerebral edema occurs due to disruption of the blood-brain barrier (BBB), leading to leakage of fluid and proteins from the blood vessels into the brain parenchyma. This type of cerebral edema is commonly associated with conditions such as brain tumors, abscesses, and ischemic stroke.
Choice B Reason:
Osmotic cerebral edema is inappropriate response. Osmotic cerebral edema occurs when there is an imbalance of osmotic forces across the blood-brain barrier, leading to the movement of water into the brain cells. This type of cerebral edema can result from conditions such as hyponatremia or the administration of hypertonic solutions.
Choice C Reason:
Cellular cerebral edema is inappropriate response. Cellular cerebral edema involves the swelling of brain cells (neurons and glial cells) due to various insults, such as ischemia, hypoxia, or metabolic disturbances. This type of cerebral edema can occur in conditions such as ischemic stroke or traumatic brain injury.
Choice D Reason:
Interstitial cerebral edema is incorrect response. Interstitial cerebral edema involves the accumulation of fluid within the interstitial spaces of the brain tissue. This type of cerebral edema can occur in conditions such as hydrocephalus, where there is obstruction of cerebrospinal fluid (CSF) flow.

Correct Answer is ["B","D","E","F"]
Explanation
Choice A Reason:
Sedatives do not impact the risk of obstructive sleep apnea: This statement is incorrect. Sedatives, particularly those that cause muscle relaxation or depress the central nervous system, can exacerbate obstructive sleep apnea by further relaxing the muscles of the upper airway, leading to increased airway collapse during sleep.
Choice B Reason:
CPAP compliance enhances quality of sleep is correct. Continuous positive airway pressure (CPAP) therapy is a common treatment for obstructive sleep apnea. Compliance with CPAP therapy, meaning consistent and proper use of the CPAP device during sleep, is essential for effectively managing sleep apnea and improving sleep quality.
Choice C Reason:
Alcohol does not affect the risk of obstructive sleep apnea. This statement is incorrect. Alcohol consumption can worsen obstructive sleep apnea by promoting muscle relaxation in the upper airway, leading to increased airway collapse and more frequent episodes of apnea during sleep.
Choice D Reason:
Obesity increases the risk of obstructive sleep apnea. This statement is correct. Obesity is a significant risk factor for obstructive sleep apnea. Excess fat tissue around the neck can increase the likelihood of airway obstruction during sleep, contributing to the development or worsening of sleep apnea.
Choice E Reason:
Positional therapy enhances client comfort is correct. Positional therapy involves strategies to encourage sleeping in positions that minimize the severity of obstructive sleep apnea, particularly for individuals with positional OSA (where apnea events are primarily or significantly worse when sleeping in specific positions, such as supine). This statement is correct.
Choice F Reason:
Smoking increases the risk of obstructive sleep apnea: This statement is correct. Smoking can increase the risk of obstructive sleep apnea due to its effects on upper airway inflammation and respiratory function. Smoking cessation can be beneficial in managing sleep apnea and improving overall health.
Correct Answer is ["B","D","E"]
Explanation
Choice A Reason:
Loss of teeth is not typically considered a direct factor contributing to obstructive sleep apnea. While the presence of teeth may play a role in maintaining the structure of the oral cavity, it is not a primary risk factor for OSA.
Choice B Reason:
Stroke is correct. Individuals who have had a stroke are at increased risk of developing obstructive sleep apnea. Stroke can cause damage to areas of the brain involved in controlling breathing and upper airway function, leading to disruptions in respiratory control during sleep.
Choice C Reason:
Sleepiness is a symptom commonly associated with obstructive sleep apnea rather than a direct contributing factor. Excessive daytime sleepiness is a consequence of disrupted sleep patterns and recurrent episodes of breathing cessation during the night, which are characteristic features of obstructive sleep apnea.
Choice D Reason:
Fatty deposits is correct. Excessive fatty deposits, particularly around the neck and throat, can contribute to the narrowing and collapse of the upper airway during sleep, increasing the risk of obstructive sleep apnea. Obesity is a significant risk factor for OSA due to the accumulation of fat deposits in the upper airway tissues.
Choice E Reason:
Muscle dysfunction is correct. Muscle dysfunction, particularly of the muscles surrounding the upper airway, can impair the ability of these muscles to keep the airway open during sleep. Weakness or dysfunction of these muscles can lead to increased collapsibility of the upper airway, contributing to obstructive sleep apnea.
