Which assessment finding would be most concerning and require immediate nursing intervention? A nurse is caring for a 3-year-old child with a suspected Wilms' tumor who was admitted for diagnostic evaluation. ## 보기 1. Palpation reveals a firm, nontender mass in the left flank 2.

Blood pressure measured at 110/70 mmHg in the right arm **정답: 2** ## 해설 Severe abdominal pain following palpation in a child with suspected Wilms' tumor is extremely concerning as it may indicate tumor rupture, which can lead to hemorrhage and seeding of cancer cells throughout the peritoneal cavity. Wilms' tumor (nephroblastoma) is the most common primary kidney tumor in children, mainly occurring between ages 2 and 5. When caring for a child with suspected Wilms' tumor, the most important consideration is to avoid excessive manipulation or palpation of the abdomen, as this can cause tumor rupture. A child with suspected Wilms' tumor complaining of severe abdominal pain after palpation is a medical emergency suggesting possible tumor rupture. Tumor rupture can lead to several life-threatening complications: bleeding from the highly vascular tumor, dissemination of malignant cells throughout the abdominal cavity (significantly worsening prognosis and staging), and potential hemodynamic instability. The correct answer (option 2) indicates possible tumor rupture and is the most concerning finding. This requires immediate medical intervention, emergency imaging, possible surgical exploration, and intensive monitoring. Such complications can change the tumor stage from localized to advanced disease, significantly affecting treatment protocols and prognosis. Priorities in Wilms' tumor nursing care include gentle handling, avoiding deep palpation, posting "do not palpate abdomen" signs, and immediately reporting any signs suggesting tumor rupture. Early recognition and intervention are crucial to prevent further complications and optimize patient outcomes. ## 심화 해설 Clinical Scenario Analysis A 3-year-old child admitted with a suspected Wilms' tumor (nephroblastoma) requires meticulous nursing assessment and monitoring. The most critical nursing responsibility in the pre-operative or diagnostic phase is the prevention of tumor rupture, as this directly upstages the disease and worsens the prognosis. Understanding Wilms' Tumor and the Risk of Rupture Wilms' tumor is the most common primary malignant renal tumor in children [1]. The tumor is typically encapsulated, and maintaining the integrity of this capsule is paramount. Preoperative tumor rupture is an uncommon but serious complication that leads to the spillage of malignant cells into the peritoneal cavity. This event automatically upstages the disease, requiring treatment intensification and negatively impacting survival outcomes [2]. The clinical presentation of a rupture can range from subtle to catastrophic. As described in the literature, a patient may present with severe abdominal pain and signs of acute abdomen when a rupture occurs [3]. Therefore, any sudden change in the child's clinical status, particularly the onset of severe pain, must be interpreted as a potential sentinel event indicating capsular disruption. Analysis of Assessment Findings - **Option 1: Palpation reveals a firm, nontender mass in the left flank.** This is a classic and expected finding for a Wilms' tumor. While it is a significant assessment finding that confirms the need for diagnostic evaluation, it does not represent an acute change requiring immediate intervention beyond the critical nursing action of avoiding palpation of the mass once it is identified to prevent rupture. The finding itself is not the emergency; the act of deep palpation is the risk. - **Option 2: Child reports sudden severe abdominal pain after abdominal palpation.** This is the most concerning finding. Sudden severe abdominal pain following manipulation of the abdomen is a classic clinical indicator of tumor rupture or hemorrhage into the tumor capsule. As noted in case reports, patients with a ruptured Wilms' tumor can present with severe abdominal pain [3]. This symptom suggests that the tumor capsule has been disrupted, leading to bleeding and peritoneal irritation. This constitutes a surgical emergency and requires immediate nursing intervention, including stopping any further manipulation, notifying the healthcare provider immediately, and initiating frequent monitoring for signs of hemodynamic instability. - **Option 3: Urinalysis shows microscopic hematuria with red blood cells.** Microscopic hematuria is a common finding in Wilms' tumor due to invasion of the collecting system by the tumor. While it is an important diagnostic clue, it is not typically an acute, life-threatening event that requires immediate intervention in the same way a rupture does. - **Option 4: Blood pressure measured at 110/70 mmHg in the right arm.** This blood pressure reading is within the normal expected range for a 3-year-old child. The systolic pressure is approximately 90 + (age in years x 2), which would be around 96 mmHg, and the diastolic is normally between 60-70 mmHg. While Wilms' tumor can cause secondary hypertension due to renin production, this value is not abnormal and does not require immediate intervention. The Critical Nursing Intervention The immediate nursing intervention for a suspected Wilms' tumor is to place a prominent sign above the patient's bed stating "DO NOT PALPATE THE ABDOMEN." This is because manual manipulation is the most common iatrogenic cause of preoperative rupture. The sudden onset of severe pain after palpation, as described in Option 2, is the clinical manifestation that this protective protocol has failed and a rupture has likely occurred. The nurse must recognize this as a sign of upstaged disease requiring urgent surgical and oncological re-evaluation [2]. The management of a rupture varies depending on hemodynamic stability, but if bleeding is not self-limited or controlled, it necessitates an emergent response [3].

Key Safety Protocols - Place a prominent "Do Not Palpate" sign above the child's bed and in the medical record. - Educate all staff, caregivers, and family members that the abdomen must not be palpated or compressed during bathing, positioning, or play. - Use gentle handling techniques for all routine care to avoid accidental trauma to the tumor site. Assessment and Monitoring - Continuously monitor for escalating signs of an acute abdomen: severe pain, distension, rigidity, guarding, and rebound tenderness. - Monitor for signs of internal hemorrhage, including increasing abdominal girth, pallor, and hemodynamic instability. - Document the exact time, character, and location of pain onset, and the child's response to any interventions. ## 핵심 개념 - **Wilms' Tumor** — Most common primary malignant kidney tumor in children. Mainly occurs between ages 2-5, with abdominal mass being the most common symptom. - **Tumor Rupture** — A state in which the tumor ruptures. In the case of Wilms tumor, this can occur due to palpation or trauma, leading to intra-abdominal bleeding and cancer cell dissemination, which can be life-threatening and worsen the stage of the disease. - **Hematuria** — Blood in the urine. It occurs in about 25% of Wilms tumor cases and suggests invasion of the kidney parenchyma. - **Abdominal Palpation** — A physical examination method where the abdomen is pressed and palpated by hand. It is absolutely contraindicated in patients with suspected or confirmed Wilms tumor and is a major cause of tumor rupture. - **Clinical Judgment** — A thinking process in which nurses collect and analyze patient data, draw conclusions, determine interventions, and evaluate outcomes. It is a core assessment component of the NGN. ## 같은 주제 문제 - [A 3-year-old child is admitted to the pediatric unit with a suspected Wilms' tumor (nephro…](https://mymerci.kr/pages/nclex_q.php?qn_id=542200) - [A 3-year-old child is admitted to the pediatric unit with a suspected Wilms' tumor (nephro…](https://mymerci.kr/pages/nclex_q.php?qn_id=542201) - [A 3-year-old child is admitted to the pediatric unit with a suspected Wilms' tumor (nephro…](https://mymerci.kr/pages/nclex_q.php?qn_id=542202) - [A 4-year-old child with Wilms' tumor is scheduled for surgery tomorrow.
