A nurse is caring for a client admitted with meningitis. The student nurse asks, "I know that the client has a lot of edemas in the brain, but what causes it?" Which of the following responses from the nurse best answers the student's question?

Choice A Reason:

Higher oxygen saturations of 98% to 99% is inappropriate. A pneumothorax involves the presence of air in the pleural space, which can compromise lung function and gas exchange. This compromised lung function typically leads to decreased oxygenation of the blood, resulting in lower oxygen saturations rather than higher saturations.

Choice B Reason:

Lower oxygen saturations of 93% to 94% is appropriate. A pneumothorax disrupts the normal exchange of oxygen and carbon dioxide in the lungs due to partial or complete lung collapse. As a result, the affected lung is unable to adequately oxygenate the blood, leading to lower oxygen saturations, which are indicative of hypoxemia.

Choice C Reason:

Lower energy expenditure is inappropriate. Energy expenditure is not typically affected by a pneumothorax. While the discomfort and respiratory distress associated with a pneumothorax may cause the individual to limit physical activity, there is no direct impact on overall energy expenditure.

Choice D Reason:

Increased lung capacity is inappropriate. A pneumothorax results in partial or complete collapse of the affected lung, reducing lung capacity rather than increasing it. The presence of air in the pleural space creates positive pressure, which can compress the lung and decrease its ability to expand fully during inhalation.

Choice A Reason:

Glatiramer acetate is incorrect because it is used in the treatment of multiple sclerosis (MS) to reduce the frequency of relapses and delay disease progression. It is not indicated for spasm-induced incontinence.

Choice B Reason:

Dulaglutide is incorrect because it is a medication used to treat type 2 diabetes by improving blood sugar control. It is not indicated for the treatment of spasm-induced incontinence.

Choice C Reason:

Montelukast sodium is incorrect because it is a leukotriene receptor antagonist primarily used to manage asthma and allergic rhinitis. It is not indicated for the treatment of spasm-induced incontinence.

Choice D Reason:

Oxybutynin is an anticholinergic medication commonly used to treat overactive bladder and urinary incontinence, including spasm-induced incontinence that can occur in individuals with spinal cord injury. It works by relaxing the smooth muscles of the bladder, thereby reducing involuntary contractions that contribute to urinary urgency and incontinence.
