Other findings (nausea/vomiting, incisional pain, low urine output) are less urgent in this context. ## 심화 해설 Understanding the Clinical Priority This question tests your ability to recognize early signs of clinical deterioration in a client with an acute Crohn's disease flare. While nausea, incisional pain, and low urine output are all concerning, they do not represent the most immediate threat to life. The correct answer is option 2, as the combination of fever and tachypnea strongly suggests a developing systemic infection or sepsis, which requires immediate intervention. Pathophysiology of the Emergency Finding Crohn's disease (CD) is characterized by transmural inflammation, meaning the inflammation extends through the entire thickness of the bowel wall. This deep, penetrating disease process creates a significant risk for serious complications. The client's fever of 38.5°C and tachypnea at 28 breaths/min are not just signs of inflammation; they are classic indicators of Systemic Inflammatory Response Syndrome (SIRS), a precursor to sepsis. The underlying mechanism connects directly to the nature of the disease. As described in the literature, CD results from a convergence of biological disturbances that disrupt intestinal homeostasis, including weakened microbial detection and epithelial protection [3]. A transmural fissure or micro-perforation can easily develop during a severe flare, allowing enteric bacteria to translocate from the gut lumen into the normally sterile peritoneal cavity. This can lead to a localized abscess or generalized peritonitis, triggering a systemic response. The tachypnea is a compensatory mechanism for the metabolic acidosis that develops as the body's tissues become hypoperfused and switch to anaerobic metabolism. This progression from a localized flare to a systemic infection is a life-threatening emergency that demands immediate diagnostic workup, fluid resuscitation, and antibiotic therapy. Analysis of Other Options Understanding why the other options are a lower priority is crucial for NCLEX-RN success. They represent expected or less urgent findings in this clinical scenario. - Option 1: Nausea and vomiting small amounts of clear fluid. Nausea and vomiting are common during a Crohn's flare due to the inflammatory process and potential partial obstruction from edema. While it requires antiemetic management and fluid balance monitoring, it is an expected finding in the context of an active flare and does not signal an immediate, life-threatening change in status. - Option 3: Incisional pain rated 6/10 at laparoscopic port sites. The mention of laparoscopic port sites indicates the client has recently undergone surgery, likely a bowel resection. Incisional pain is an expected post-operative finding. While pain management is a nursing priority, a pain score of 6/10 is not an immediate emergency compared to signs of sepsis. A sudden, severe increase in pain could indicate dehiscence or perforation, but as a stable finding, it is a lower priority. - Option 4: Urinary output of 25 mL/hour for the past 2 hours. A urinary output of less than 30 mL/hour is a sign of impaired renal perfusion, often due to dehydration from diarrhea or third-spacing of fluid into the inflamed bowel. This finding indicates acute kidney injury risk and requires prompt intervention, such as increasing IV fluid rates. However, it is a secondary effect of the underlying disease process. The immediate threat is the systemic infection (option 2) that could be causing or exacerbating the hypovolemia and organ dysfunction. In a prioritization framework, the systemic infection takes precedence over the single-organ effect. NCLEX-RN Prioritization Framework This question requires you to apply the ABC (Airway, Breathing, Circulation) and safety prioritization framework. Option 2 involves "Breathing" (tachypnea) and "Circulation" (the systemic effects of sepsis), placing it in the highest-acuity category. The clinical presentation points to a breach in the intestinal barrier, a concept supported by the understanding of CD as a transmural disease that can lead to lymphatic obstruction and deep ulceration [4]. A client with a flare who develops a fever and tachypnea should be immediately assessed for peritoneal signs, and the healthcare provider must be notified without delay to initiate sepsis protocols.References (research sources) - [3]Crohn's Disease: From Immune Dysregulation to Intestinal Damage.Research articleSalvatori S, Frascatani R, De Vico P, Marafini I, Monteleone G.

A new fever of 38.5°C with tachypnea of 28 breaths/min is a classic SIRS response, signaling possible peritonitis or abscess. This systemic infection is the immediate priority over other assessment findings like incisional pain, nausea, or mild oliguria. The tachypnea is often an early compensatory mechanism for metabolic acidosis from sepsis. CautionDo not dismiss tachypnea as anxiety. In a patient with a Crohn's flare and fever, it is a critical red flag for clinical deterioration requiring immediate provider notification and sepsis protocol initiation. ## 핵심 개념 - **Systemic Inflammatory Response Syndrome (SIRS)** — A clinical syndrome characterized by systemic inflammation, often triggered by infection or non-infectious insults like pancreatitis or trauma, and identified by abnormalities in temperature, heart rate, respiratory rate, and white blood cell count. - **Sepsis** — A life-threatening organ dysfunction caused by a dysregulated host response to infection, often presenting with fever, tachypnea, tachycardia, and altered mental status, and requiring urgent medical intervention. - **Transmural Inflammation** — Inflammation affecting the entire thickness of the bowel wall, a hallmark of Crohn's disease that predisposes to complications such as strictures, fistulas, and perforation. - **Tachypnea** — An abnormally rapid respiratory rate, often a compensatory mechanism for metabolic acidosis in sepsis as the body attempts to eliminate carbon dioxide to normalize blood pH. - **Bacterial Translocation** — The passage of viable bacteria or their products from the gastrointestinal lumen to normally sterile extraintestinal sites, such as mesenteric lymph nodes or the bloodstream, facilitated by a compromised intestinal mucosal barrier. ## 같은 주제 문제 - [A nurse is assessing a 52-year-old patient 6 hours after laparoscopic sleeve gastrectomy. …](https://mymerci.kr/pages/nclex_q.php?qn_id=540524) - [A nurse is assessing a 35-year-old patient 2 days after laparoscopic sleeve gastrectomy.
