The patient reports severe lower abdominal pain and has been unable to urinate since the accident 3 hours ago. Initial assessment reveals a distended bladder and hematuria. What is the most appropriate initial nursing intervention? Emergency management of suspected bladder trauma with urinary retention ## 보기 1. Insert a urinary catheter immediately to relieve bladder distension 2. Encourage the patient to drink fluids to promote urination 3. Apply heat to the lower abdomen to relax bladder muscles 4. Notify the physician immediately and prepare for cystoscopy **✔ 정답** **정답: 4** ## 해설 Immediate physician notification is essential in suspected bladder trauma to avoid interventions like catheter insertion that could worsen the injury. Cystoscopy is needed for definitive diagnosis and management. ## 심화 해설 Understanding the Clinical Scenario This patient presents with classic signs of lower urinary tract injury following blunt abdominal trauma: severe lower abdominal pain, a palpable distended bladder, gross hematuria, and an inability to void. In the context of a high-velocity motor vehicle accident, these findings raise immediate concern for a bladder rupture, which can be intraperitoneal or extraperitoneal. The inability to urinate despite a full bladder strongly suggests a structural disruption rather than a simple functional obstruction. Why Immediate Catheterization Is Contraindicated The instinct to immediately decompress the bladder with a urinary catheter (Option 1) is understandable but potentially dangerous here. In suspected bladder trauma, a standard blind catheter insertion can convert a partial tear into a complete rupture, introduce infection into a sterile hematoma, or cause the catheter to pass through the defect into the peritoneal cavity. While the consensus recommendations in the provided guideline [1] emphasize evidence-based catheter management to prevent hospital-onset urinary tract infections, the foundational principle is that catheterization must only occur after the integrity of the lower urinary tract has been confirmed. In trauma, this confirmation requires imaging, typically a retrograde cystogram, which is a physician-driven diagnostic procedure. The systematic review on catheter-related bladder discomfort and the RCT on catheter fixation both address the management of catheters already in place, not the decision of when to place one in a potentially ruptured bladder. Evaluating the Remaining Options Options 2 and 3 are not only ineffective but harmful. Encouraging fluid intake (Option 2) to promote urination in a patient with a suspected bladder rupture would increase intravesical pressure, forcing urine through the defect into the peritoneal cavity or pelvic soft tissues, worsening chemical peritonitis and tissue damage. Applying heat (Option 3) addresses muscle spasm, not a structural defect, and delays definitive diagnosis and repair. The Priority Nursing Action: Facilitate Definitive Diagnosis The most appropriate initial nursing intervention is to notify the physician immediately and prepare for diagnostic procedures (Option 4). The standard of care for suspected bladder trauma with urinary retention is a retrograde cystogram, often performed in conjunction with a CT cystogram. This study is performed by injecting contrast dye through a catheter under controlled conditions after the urethra has been cleared of injury. Preparing for this involves gathering supplies, ensuring informed consent is obtained by the physician, and maintaining the patient on NPO status in anticipation of possible surgical repair. The pilot study on FAST examination highlights how nurses in the emergency department can be trained to assist with and even perform focused assessments to rapidly detect free fluid, a finding that would support the diagnosis of intraperitoneal bladder rupture and underscore the urgency of surgical consultation. While the nurse in this scenario is not performing the FAST exam, the principle of facilitating rapid, physician-led diagnostic evaluation is the core nursing responsibility. A positive FAST scan showing free fluid in the pelvis would directly corroborate the suspected diagnosis and expedite the patient's transfer to the operating room. The nurse's role is to recognize that the clinical triad of trauma, a distended bladder, and hematuria is a urologic emergency requiring a retrograde urethrogram and cystogram before any catheter is passed, making immediate physician notification the critical first step.References (research sources) - [1]Prevention Strategies for All Hospital-Onset Urinary Tract Infections: Best Practice Consensus Recommendations.GuidelineSeptimus EJ, Arya LA, Crapanzano-Sigafoos R, Dmochowski R, Dy O, Emer-Seltun J, Engberg S, Garcia R, Gray M, Kennelly M, Krein S, Meddings J, Murthy R, Newman DK, Pettis A, Reese S, Sidlow E, Vollman K. (2026) · DOI: 10.1093/ofid/ofag060 ## 임상 시나리오 Clinical Practice Guide: Bladder Trauma In a patient with blunt abdominal trauma and suspected bladder injury, the priority is to avoid any intervention that could exacerbate the damage. The classic triad includes suprapubic pain, hematuria, and inability to void despite a palpable bladder. Key Nursing Actions - **Do Not Catheterize Blindly:** Withhold urinary catheter insertion until the physician evaluates the patient and the integrity of the lower urinary tract is confirmed via imaging (e.g., retrograde cystogram). Blind insertion risks converting a partial tear into a complete rupture or introducing infection. - **Immediate Physician Notification:** Promptly report the assessment findings (distended bladder, gross hematuria, inability to void) to the physician. This is a surgical emergency requiring urgent diagnostic workup. - **Prepare for Diagnostics:** Anticipate the need for a retrograde cystogram or CT cystography. Prepare the patient for a potential cystoscopy in the operating room if a rupture is confirmed. - **Monitor Closely:** Continuously monitor vital signs for signs of hypovolemic shock, as pelvic and bladder injuries can be associated with significant hemorrhage. Assess the abdomen for increasing distention or rigidity. Rationale for Avoiding Common Pitfalls - **Fluid Administration:** Do not encourage oral fluids. The patient cannot void, and increasing bladder volume will worsen distention and pain without therapeutic benefit. Maintain NPO status in case surgical intervention is required. - **Heat Application:** Superficial heat does not address a structural defect and delays definitive care. It may also mask or alter pain presentation. ## 핵심 개념 - **Bladder Rupture** — A structural disruption of the bladder wall, often caused by blunt trauma, classified as intraperitoneal or extraperitoneal, requiring surgical repair or catheter drainage. - **Retrograde Cystogram** — A diagnostic imaging study where contrast dye is instilled into the bladder via a catheter under fluoroscopy to evaluate for leaks or injury. - **Hematuria** — The presence of blood in the urine, which in a trauma setting is a key indicator of potential genitourinary tract injury. - **Cystoscopy** — An endoscopic procedure allowing direct visualization of the urethra and bladder, used to diagnose and sometimes manage bladder trauma. - **Urinary Retention** — The inability to voluntarily empty the bladder, which in trauma may signal a mechanical disruption or obstruction rather than a functional cause. ## 같은 주제 문제 - [A nurse is assessing a 35-year-old male patient who sustained blunt abdominal trauma in a …](https://mymerci.kr/pages/nclex_q.php?qn_id=541525) - [A nurse is assessing a patient who sustained blunt abdominal trauma in a motor vehicle acc…](https://mymerci.kr/pages/nclex_q.php?qn_id=541526) - [A 28-year-old male patient presents to the emergency department following a motorcycle acc…](https://mymerci.kr/pages/nclex_q.php?qn_id=541527) - [A nurse is caring for a patient with suspected bladder trauma following a motor vehicle ac…](https://mymerci.kr/pages/nclex_q.php?qn_id=541528) - [A nurse is caring for a patient who sustained blunt abdominal trauma in a motor vehicle ac…](https://mymerci.kr/pages/nclex_q.php?qn_id=541530) - [A patient with suspected bladder trauma following a motor vehicle accident is admitted to …](https://mymerci.kr/pages/nclex_q.php?qn_id=541531) - [A 28-year-old male patient is admitted to the emergency department following a motor vehic…](https://mymerci.kr/pages/nclex_q.php?qn_id=541532) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
