Which nursing action is the highest priority to ensure patient safety? What is the most critical safety measure when caring for a child with suspected Wilms' tumor during the diagnostic phase? ## 보기 1. Encourage the child to drink plenty of fluids before imaging procedures 2. Avoid palpating the abdomen and place a sign on the bed stating "DO NOT PALPATE ABDOMEN" **✔ 정답** 3. Position the child in a prone position to reduce abdominal pressure 4. Apply gentle abdominal massage to assess for pain response **정답: 2** ## 해설 The most critical safety measure for a child with suspected Wilms' tumor is to avoid abdominal palpation and ensure all healthcare team members are aware of this restriction. Wilms' tumor (nephroblastoma) is the most common primary kidney tumor in children, typically occurring between ages 2 and 5. This tumor presents as a large, encapsulated mass that is very fragile and prone to rupture with even minimal manipulation. The most important safety measure is to avoid abdominal palpation. Applying pressure or manipulating the abdomen can cause the tumor to rupture, spreading malignant cells throughout the abdominal cavity. This complication significantly worsens the prognosis and cancer staging, potentially converting a localized tumor (stage 1 or 2) to an advanced stage (stage 3 or 4) with peritoneal contamination. Placing a clear sign on the bed stating "No Abdominal Palpation" ensures that all healthcare personnel—including doctors, nurses, students, and other team members—are immediately aware of this critical safety restriction. This prevents accidental palpation during routine assessments or examinations. The encapsulated nature of Wilms' tumor makes it especially vulnerable to rupture. Even light palpation during a physical exam can disrupt the tumor capsule, releasing cancer cells into the peritoneal cavity. Such a rupture alters the entire treatment approach, requiring more aggressive chemotherapy and radiation therapy. This safety measure is so crucial that it takes precedence over other nursing assessments and interventions. The abdomen should only be visually inspected for distension, asymmetry, or visible masses, and should never be palpated until after surgical removal of the tumor. ## 심화 해설 Understanding the Priority Safety Concern in Wilms' Tumor When a child is admitted with a suspected diagnosis of nephroblastoma, or Wilms' tumor, the nursing priority during the diagnostic phase is to prevent iatrogenic harm. Wilms' tumor is a highly vascular, encapsulated renal mass. The critical danger lies in the fact that the tumor's capsule is fragile and can easily rupture with physical manipulation of the abdomen. Why Palpation is Contraindicated The highest priority nursing action is to avoid palpating the abdomen and to place a clear visual warning, such as a sign reading "DO NOT PALPATE ABDOMEN," on the patient's bed. The rationale is rooted in the principles of pediatric surgical oncology. Rupture of the tumor capsule from palpation, even gentle examination, can cause tumor spillage within the peritoneal cavity. This immediately upstages the disease, changing it from a localized tumor to a more advanced stage, which necessitates more aggressive chemotherapy and radiation, and significantly worsens the prognosis. The foundational surgical guidelines for pediatric solid tumors emphasize that adherence to sound oncological principles is closely associated with improved local control and survival [2]. Avoiding unnecessary abdominal manipulation is a fundamental, non-negotiable principle of these safety protocols. Analysis of Incorrect Options The other options represent actions that are either inappropriate or directly harmful in this specific clinical context. - Option 1 (Encourage the child to drink plenty of fluids): This is not the highest priority and could be counterproductive. While hydration is generally important, a child with a large abdominal mass may have gastrointestinal compression, leading to nausea or early satiety. Forcing fluids is not a critical safety measure related to the tumor itself. - Option 3 (Position the child in a prone position): Placing a child with a large abdominal mass in a prone position would increase direct pressure on the tumor, which is the exact opposite of the protective measure needed. This could cause discomfort and increase the risk of capsular rupture. - Option 4 (Apply gentle abdominal massage to assess for pain response): This action is strictly contraindicated. Any form of abdominal massage, no matter how gentle, applies direct mechanical force to the tumor, dramatically increasing the risk of rupture and tumor spillage. The primary goal of the diagnostic phase, as outlined in surgical practice guidelines, is to safely obtain a diagnosis and stage the disease without causing harm [2]. The evolution of surgical approaches, including nephron-sparing surgery for bilateral cases, highlights the critical importance of preserving the tumor capsule and renal parenchyma, a goal that begins with meticulous pre-operative handling . The immediate, life-altering risk of tumor rupture from palpation makes its prevention the unequivocal highest safety priority during the initial care of a child with suspected Wilms' tumor.References (research sources) - [2]International Society of Paediatric Surgical Oncology (IPSO) Surgical Practice Guidelines.Guidelinede Campos Vieira Abib S, Chui CH, Cox S, Abdelhafeez AH, Fernandez-Pineda I, Elgendy A, Karpelowsky J, Lobos P, Wijnen M, Fuchs J, Hayes A, Gerstle JT.

The tumor's capsule is fragile and can rupture, leading to tumor spillage. Place a clear, visible sign reading "DO NOT PALPATE ABDOMEN" on the patient's bed and ensure it is communicated to all healthcare team members. CautionRupture from palpation immediately upstages the disease, requiring more aggressive chemotherapy and radiation, and significantly worsens the prognosis. Never perform abdominal massage or deep palpation. ## 핵심 개념 - **Wilms Tumor (Nephroblastoma)** — A highly vascular, encapsulated renal malignancy in children where the tumor capsule is fragile and prone to rupture upon palpation. - **Tumor Spillage** — The rupture of a tumor capsule causing cancer cells to spread within the peritoneal cavity, which immediately upstages the disease and worsens prognosis. - **Iatrogenic Harm** — Preventable patient harm caused by medical examination or treatment; in this context, tumor rupture from abdominal palpation. - **Disease Upstaging** — The progression of cancer to a more advanced stage, often necessitating more aggressive therapy and associated with a poorer outcome. ## 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 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=542203) - [A 4-year-old child with Wilms' tumor is scheduled for surgery tomorrow.
