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:

Paralytic ileus is incorrect. Paralytic ileus is a condition characterized by obstruction of the intestines due to paralysis of the intestinal muscles, resulting in symptoms such as abdominal pain, bloating, and constipation. Paralytic ileus is not typically associated with cauda equina syndrome, which primarily affects the nerves in the lower back and lower extremities.

Choice B Reason:

Blood pressure 80/48 mm Hg is incorrect. While cauda equina syndrome can cause neurological symptoms such as lower extremity weakness, numbness, and bowel or bladder dysfunction, it is not typically associated with alterations in blood pressure. Blood pressure changes may occur in response to pain or other systemic factors, but they are not specific to cauda equina syndrome.

Choice C Reason:

Weakness in one or both legs is correct. Yes, weakness in one or both legs is a characteristic finding of cauda equina syndrome. Compression of the nerve roots in the lower spinal cord can lead to motor deficits, including weakness, difficulty walking, and loss of reflexes in the lower extremities.

Choice D Reason:

Potassium 3.2 mEq/L is incorrect. Serum potassium levels are not typically associated with cauda equina syndrome. Abnormal potassium levels may be indicative of electrolyte imbalances, which can occur in various medical conditions but are not specific to cauda equina syndrome.

Choice A Reason:

Epithelial cells is correct. Epithelial cells lining the airways play a role in initiating the inflammatory response in asthma by releasing cytokines and other inflammatory mediators. These cells can contribute to the circulatory surge of inflammatory cells and cytokines seen in status asthmaticus.

Choice B Reason:

OT lymphocytes is incorrect. There is no specific cell type known as "OT lymphocytes." It's possible this may refer to T lymphocytes (T cells), which are involved in the immune response in asthma but are not typically associated with a circulatory surge in status asthmaticus.

Choice C Reason:

Hyperreactivity is incorrect. Hyperreactivity refers to the exaggerated response of the airways to various stimuli, leading to bronchoconstriction and inflammation. While hyperreactivity is a characteristic feature of asthma, it does not directly contribute to a circulatory surge of inflammatory cells and cytokines.

Choice D Reason:

Mast cells is correct. Mast cells are key players in the pathophysiology of asthma. They release various inflammatory mediators, including histamine and leukotrienes, which contribute to airway inflammation, bronchoconstriction, and mucus production. Mast cells can participate in the circulatory surge of inflammatory cells and cytokines in status asthmaticus.

Choice E Reason:

Inflammation is correct. Inflammation is a hallmark feature of asthma and plays a central role in the pathogenesis of status asthmaticus. The inflammatory response involves the recruitment and activation of various inflammatory cells, release of cytokines, and other mediators that contribute to airway obstruction and systemic effects.
