A nurse is caring for a client who has multiple sclerosis and is experiencing progressive multifocal leukoencephalopathy (PML). Which of the following medications should the nurse recognize is associated with the development of PML?

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.

Choice A Reason:

Hypertension is not typically associated with heterotopic ossifications. However, it may occur in individuals with spinal cord injuries (SCI) due to autonomic dysreflexia, a condition characterized by an exaggerated sympathetic response to stimuli below the level of injury. Autonomic dysreflexia can lead to a sudden increase in blood pressure, which, if left untreated, can result in complications such as stroke or seizure. However, hypertension is not directly related to heterotopic ossifications.

Choice B Reason:

Bradycardia is also not typically associated with heterotopic ossifications. Like hypertension, bradycardia may occur in individuals with SCI due to autonomic dysreflexia. Autonomic dysreflexia can lead to a sudden increase in blood pressure and a reflex bradycardia in response to the increased sympathetic outflow. However, bradycardia is not directly related to heterotopic ossifications.

Choice C Reason:

Fecal impaction is a potential complication of spinal cord injury (SCI) due to impaired bowel function, but it is not directly related to heterotopic ossifications. SCI can disrupt normal bowel motility and result in neurogenic bowel dysfunction, leading to symptoms such as constipation, fecal impaction, and bowel obstruction. However, fecal impaction is not specific to heterotopic ossifications.

Choice D Reason:

Arthralgia is correct. Heterotopic ossifications (HO) involve the abnormal formation of bone in soft tissues around joints, muscles, tendons, or ligaments. When HO occurs around joints, it can lead to symptoms such as pain, swelling, and decreased range of motion, collectively known as arthralgia. Therefore, arthralgia is a common finding associated with heterotopic ossifications in individuals with spinal cord injuries.
