A patient returns to the clinic after a regimen of antibiotics for a wound that is not healing. The provider is unsure of the type of organism infecting the wound. Which diagnostic would the nurse expect to perform in this scenario?

A. Corticosteroids increase the immune response and enhance inflammation, aggravating symptoms:Corticosteroids inhibit multiple inflammatory pathways rather than stimulating them. Increasing immune activity would worsen mucosal inflammation in inflammatory bowel disease. This mechanism is opposite to the therapeutic goal of corticosteroid therapy.

B. Corticosteroids balance electrolytes and water in the body, improving gut motility:Although corticosteroids can affect fluid and electrolyte balance as a side effect, this is not the therapeutic mechanism in inflammatory bowel disease. Symptom relief occurs through anti-inflammatory effects on the intestinal mucosa.

C. Corticosteroids suppress the immune system and reduce inflammation, helping to improve symptoms in inflammatory bowel disease:Corticosteroids decrease leukocyte migration and inhibit the release of inflammatory mediators in the intestinal wall. Reduced inflammation leads to decreased edema, ulceration, and mucosal damage. This mechanism helps control disease flares and improve clinical symptoms.

D. Corticosteroids increase the production of proinflammatory cytokines, improving symptoms in inflammatory bowel disease:Corticosteroids reduce the production of proinflammatory cytokines such as interleukins and tumor necrosis factor. Increasing cytokine production would intensify intestinal inflammation.

A. Complete blood count with platelet count:Valproic acid can rarely cause thrombocytopenia, but yellowing of the eyes and skin (jaundice) indicates a potential liver issue rather than a blood cell abnormality. CBC is not the first priority here.

B. Liver function tests:Jaundice suggests hepatotoxicity, a known serious adverse effect of valproic acid. Liver function tests (AST, ALT, bilirubin) are essential to assess liver injury and guide whether the medication should be discontinued or adjusted.

C. Serum sodium level:Serum sodium is not related to the symptoms of jaundice. While valproic acid does not typically affect sodium levels, hyponatremia would not explain yellowing of the skin or eyes.

D. Blood glucose level:Blood glucose monitoring is unrelated to valproic acid-induced jaundice. Hyperglycemia or hypoglycemia would not present with yellowing of the skin or eyes.
