A nurse notices clear fluid on the surgical dressing of a patient who has just returned from lumbar spinal surgery. What should be the nurse’s immediate course of action?

The correct answer is Choice A

Choice A rationale: Crohn’s disease involves transmural inflammation of the gastrointestinal tract, often leading to hypermotility and increased peristalsis. Activity restriction reduces sympathetic stimulation, thereby minimizing intestinal motility and mechanical stress on inflamed mucosa. This helps prevent exacerbation of symptoms and promotes mucosal rest. By limiting physical exertion, the body can redirect energy toward immune modulation and tissue repair. Normal bowel motility varies, but excessive activity worsens inflammation and nutrient malabsorption in Crohn’s pathology.

Choice B rationale: While diarrhea is a common symptom in Crohn’s disease, activity restriction does not directly modulate stool frequency or water reabsorption. Diarrhea results from mucosal damage, cytokine-mediated secretion, and impaired absorption, not physical activity. Management typically involves anti-inflammatory agents, antidiarrheals, and dietary modifications. Restricting movement may indirectly reduce diarrhea by decreasing intestinal stimulation, but it is not the primary mechanism. Stool water content normally ranges from 60–85%, and inflammation disrupts this balance.

Choice C rationale: Healing in Crohn’s disease is multifactorial, involving immunosuppression, mucosal regeneration, and nutritional support. While rest contributes to systemic recovery, it is not the primary driver of mucosal healing. Healing requires suppression of TNF-alpha, IL-6, and other pro-inflammatory mediators. Activity restriction may support healing indirectly by reducing metabolic demand and stress hormone release, but pharmacologic and nutritional interventions are more central. Normal mucosal turnover occurs every 3–5 days, but inflammation delays this process.

Choice D rationale: Abdominal pain in Crohn’s disease arises from transmural inflammation, bowel distension, and neural sensitization. Although rest may reduce visceral stimulation, pain control is better achieved through anti-inflammatory therapy, bowel rest, and analgesics. Activity restriction does not directly modulate nociceptive pathways or cytokine levels. Pain perception involves complex neuroimmune interactions, and physical rest alone cannot address the underlying pathology. Normal visceral pain thresholds are altered in Crohn’s due to chronic inflammation and fibrosis.

Choice A rationale
Determining the presence of ST-elevations or non-ST-elevations on the electrocardiogram is an important step in diagnosing a myocardial infarction. However, this is typically performed by a healthcare provider or a trained technician, not a nurse.
Choice B rationale
While creating a calm and quiet environment can be beneficial for a client experiencing chest pain, it is not the immediate intervention that should be performed. The client’s symptoms suggest a possible cardiac event, which requires immediate medical intervention.
Choice C rationale
Verifying that troponin level assessments are scheduled every 3-6 hours for a series of three is important for diagnosing myocardial infarction. However, this is not the immediate intervention that should be performed. The client’s symptoms suggest a possible cardiac event, which requires immediate medical intervention.
Choice D rationale
Applying oxygen via nasal cannula and titrating to keep oxygen saturation above 93% is the correct intervention. This action helps to increase the oxygen supply to the myocardium, potentially decreasing the extent of myocardial damage and relieving chest pain.
