A client is hospitalized with an inflammatory bowel disease (IBD) exacerbation and is being treated with a corticosteroid. The client develops a rigid abdomen with rebound tenderness. Which action should the nurse take?

Choice A reason: Obtaining a soft diet for the client is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. A soft diet can help reduce the irritation and discomfort of the oral mucosa, but it does not address the underlying cause of the inflammation and infection. The nurse should first assess the client's oral hygiene and provide appropriate interventions to prevent further complications.

Choice B reason: Encouraging frequent mouth care is the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. Frequent mouth care can help prevent or reduce the severity of mucositis by removing plaque, bacteria, and debris from the oral cavity, and by moisturizing and soothing the oral tissues. The nurse should instruct the client to use a soft toothbrush, a mild toothpaste, and a saline or bicarbonate rinse at least four times a day, and to avoid alcohol, tobacco, spicy, acidic, or hot foods and beverages.

Choice C reason: Cleansing the tongue and mouth with swabs is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. Swabs can be abrasive and damaging to the oral mucosa, especially if they are dry or contain alcohol or hydrogen peroxide. Swabs can also increase the risk of bleeding, infection, and ulceration of the oral tissues. The nurse should use a soft toothbrush or a gentle sponge to clean the tongue and mouth.

Choice D reason: Administering a topical analgesic per protocol is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. A topical analgesic can provide temporary relief of pain and discomfort, but it does not address the underlying cause of the inflammation and infection. The nurse should first assess the client's oral hygiene and provide appropriate interventions to prevent further complications. The nurse should also monitor the client's response to the analgesic and report any adverse effects or inadequate pain control.

Choice A reason: This is incorrect because the humoral immune response involves B cells that produce antibodies against specific antigens. However, AIDS affects the cellular immune response, which involves T cells that activate other immune cells and directly kill infected cells.

Choice B reason: This is correct because AIDS is caused by human immunodeficiency virus (HIV), which infects and destroys CD4+ T cells, also known as helper T cells. These cells are essential for initiating and regulating both humoral and cellular immunity. Without enough CD4+ T cells, the body cannot mount an effective response against pathogens, especially opportunistic infections that take advantage of a weakened immune system.

Choice C reason: This is incorrect because bone marrow suppression of white blood cells is not a direct consequence of AIDS. However, some drugs used to treat AIDS, such as zidovudine, may cause bone marrow suppression as a side effect.

Choice D reason: This is incorrect because exposure to multiple environmental infectious agents does not cause AIDS. However, people with AIDS are more susceptible to infections from various sources due to their impaired immune system.
