The pain is diffuse and worsening. Which assessment finding would be the most concerning and require immediate notification of the healthcare provider? ## 보기 1. Temperature of 100.2°F (37.9°C) with mild leukocytosis 2. Positive McBurney's point tenderness with guarding 3. Sudden cessation of pain with abdominal distention and rigidity **✔ 정답** 4. Anorexia and difficulty walking due to abdominal discomfort **정답: 3** ## 해설 Sudden cessation of pain with abdominal distention and rigidity suggests appendiceal rupture, a surgical emergency. Other options (fever/leukocytosis, McBurney's tenderness, anorexia) are common in appendicitis but not urgent. ## 심화 해설 Clinical Reasoning and Pathophysiology The patient’s initial presentation of diffuse, worsening abdominal pain over 6 hours is consistent with the early visceral phase of acute appendicitis. At this stage, the appendix is distended and inflamed, stimulating visceral afferent nerve fibers, which results in poorly localized periumbilical pain. The most critical transition in the disease process occurs when the intraluminal pressure exceeds capillary perfusion pressure, leading to ischemia, necrosis, and ultimately perforation of the appendiceal wall [4]. The natural time course of perforation can be highly variable, and while some studies explore delayed appendectomy, the risk of perforation is a dynamic and time-sensitive threat [4]. When perforation occurs, the previously distended appendix suddenly decompresses. This results in the abrupt cessation of the patient's visceral pain. However, this is not a sign of improvement; it is a perilous clinical signal indicating the release of enteric contents into the peritoneal cavity. The subsequent chemical and bacterial contamination triggers diffuse peritonitis, which manifests physically as a rigid, board-like abdomen and progressive distention . The finding of sudden pain cessation coupled with abdominal rigidity is the hallmark of a perforated appendix with generalized peritonitis, representing a surgical emergency that demands immediate notification of the healthcare provider. Analysis of Assessment Findings - Option 1: A temperature of 100.2°F (37.9°C) with mild leukocytosis is a common physiological response to localized inflammation. While these findings support the diagnosis of appendicitis, they do not indicate a catastrophic complication like perforation. - Option 2: Positive McBurney's point tenderness with guarding is a classic sign of localized peritonitis during the parietal phase of appendicitis, where the inflamed appendix irritates the parietal peritoneum. This is an expected and diagnostically significant finding but does not signify perforation and generalized peritonitis. - Option 3: The sudden cessation of pain with abdominal distention and rigidity is the most concerning finding. It signifies the transition from localized inflammation to a perforated viscus with diffuse peritonitis, a life-threatening condition requiring emergent surgical intervention. - Option 4: Anorexia and difficulty walking due to abdominal discomfort are common constitutional and protective symptoms associated with the inflammatory process of appendicitis. They are non-specific and do not carry the same immediate life-threatening implications as signs of perforation.References (research sources) - [4]The Time Course of Perforation and Abscess Formation in Appendicitis.Research articleAndresson G, Kristínardóttir ÁS. (2026) · DOI: 10.1002/wjs.70293 ## 임상 시나리오 Clinical Practice Guide: Recognizing a Perforated Appendix Pathophysiology of Perforation Acute appendicitis progresses from luminal obstruction and distension to ischemia and necrosis as intraluminal pressure exceeds capillary perfusion pressure. Perforation releases enteric contents into the peritoneal cavity, causing chemical and bacterial peritonitis. The classic deceptive sign is the sudden relief of visceral pain as the distended appendix decompresses, immediately followed by the onset of diffuse peritoneal signs. Critical Assessment Findings - **Sudden pain cessation:** A pre-perforation warning sign that must never be interpreted as clinical improvement. - **Abdominal rigidity:** Involuntary, board-like stiffness of the abdominal wall indicating generalized peritonitis. - **Distention:** Progressive abdominal swelling due to paralytic ileus and fluid accumulation. - **Systemic signs:** High fever, tachycardia, and hypotension may indicate sepsis from peritoneal contamination. Immediate Nursing Actions - Notify the healthcare provider immediately; this is a surgical emergency. - Keep the patient NPO (nothing by mouth) in preparation for emergency surgery. - Initiate intravenous fluid resuscitation as ordered to manage hypovolemia and sepsis. - Administer broad-spectrum antibiotics as prescribed. - Prepare the patient for urgent diagnostic studies (e.g., CT scan) and operative intervention. Differential Red Flags While localized guarding and McBurney's point tenderness indicate localized peritonitis, the combination of pain cessation and diffuse rigidity marks the transition to a generalized, life-threatening process. Do not delay care to administer opioid analgesia; pain relief can be provided after the surgeon's evaluation without masking the abdominal exam. ## 핵심 개념 - **Peritonitis** — Inflammation of the peritoneum, the tissue lining the inner abdominal wall and covering the abdominal organs, often caused by infection from a perforated organ. - **McBurney's point** — A point on the lower right abdomen that is one-third of the distance from the anterior superior iliac spine to the umbilicus, representing the most common location of the appendix. - **Guarding** — Voluntary or involuntary contraction of the abdominal wall muscles to protect inflamed abdominal organs from the pain of palpation. - **Visceral pain** — Poorly localized, dull, or crampy pain arising from the internal organs, often felt in the midline due to the stimulation of visceral afferent nerves. - **Rigidity** — Involuntary, board-like stiffness of the abdominal muscles, a classic sign of peritoneal inflammation and a surgical emergency. ## 같은 주제 문제 - [Which assessment finding would be most characteristic of acute appendicitis?](https://mymerci.kr/pages/nclex_q.php?qn_id=540597) - [A nurse is caring for a client with acute appendicitis who is scheduled for an appendectom…](https://mymerci.kr/pages/nclex_q.php?qn_id=540598) - [A 45-year-old patient is admitted to the emergency department with suspected acute appendi…](https://mymerci.kr/pages/nclex_q.php?qn_id=540599) - [A nurse is caring for a patient with suspected appendicitis.
