A nurse is teaching a client who has multiple sclerosis about factors that can worsen their manifestations. Which of the following factors should the nurse include in the teaching?

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.

Choice A Reason:

Genetics is correct. There is evidence to suggest that genetics play a role in the development of multiple sclerosis. Although no single gene has been identified as the cause of MS, certain genetic variations have been associated with an increased risk of developing the disease. Having a first-degree relative with MS increases an individual's risk, although the overall genetic contribution to MS susceptibility is thought to be relatively modest.

Choice B Reason:

Environmental factors is correct. Environmental factors are believed to play a significant role in the development of multiple sclerosis, particularly in individuals with a genetic predisposition. Factors such as vitamin D deficiency, smoking, exposure to certain infections (such as Epstein-Barr virus), and geographic location (latitude) have been implicated as potential triggers for MS development.

Choice C Reason:

Upper respiratory infections is incorrect. While infections may trigger exacerbations or relapses in individuals with existing multiple sclerosis, there is limited evidence to suggest that upper respiratory infections contribute directly to the development of MS. However, some research suggests that viral infections, particularly those occurring during childhood or adolescence, may influence the risk of developing MS later in life.

Choice D Reason:

Autoimmune factors is correct. Multiple sclerosis is widely recognized as an autoimmune disease, characterized by immune-mediated inflammation and damage to the central nervous system. In MS, the immune system mistakenly attacks myelin, the protective covering of nerve fibers, leading to demyelination and neurological dysfunction. Autoimmune factors are therefore considered central to the pathogenesis of MS.

Choice E Reason:

Urinary tract infections is incorrect. While urinary tract infections (UTIs) are common in individuals with multiple sclerosis due to bladder dysfunction associated with the disease, there is no direct evidence to suggest that UTIs contribute to the development of MS.
