What is the most appropriate initial nursing intervention? ## 보기 1. Attempt digital rectal stimulation to promote meconium passage 2. Administer glycerin suppository to stimulate bowel movement 3. Maintain NPO status and prepare for surgical consultation **✔ 정답** 4. Begin frequent feeding to promote intestinal motility **정답: 3** ## 해설 Maintaining NPO status prevents further intestinal distension and complications like perforation, while surgical consultation is essential for definitive correction of imperforate anus. Other options (rectal stimulation, suppository, feeding) are contraindicated as they can worsen obstruction or cause injury. ## 심화 해설 Understanding Imperforate Anus Imperforate anus is a congenital anomaly where the anal opening is absent or abnormally positioned. In this condition, the rectum ends in a blind pouch that fails to connect to the anus, preventing the normal passage of meconium and stool. This represents a complete mechanical bowel obstruction in the newborn period. Why Option 3 is Correct The most appropriate initial nursing intervention is to maintain NPO (nothing by mouth) status and prepare for surgical consultation. The rationale is grounded in the fundamental pathophysiology of the defect. Because the gastrointestinal tract is completely obstructed, any attempt to introduce fluids or feeding would increase intraluminal pressure without the possibility of distal passage, heightening the risk of aspiration, bowel perforation, and clinical deterioration. The priority is to keep the bowel decompressed and the stomach empty. Simultaneously, a prompt surgical consultation is essential, as definitive management requires operative correction. As highlighted in the literature on complex anorectal malformations, multi-disciplinary collaboration between neonatology and pediatric surgery is paramount to achieving safe outcomes from the moment of diagnosis [2]. In some cases, a staged surgical approach is necessary, where an initial enterostomy is performed in the neonatal period to relieve the obstruction, followed by a definitive anoplasty later in infancy . The nurse’s immediate role is to stabilize the newborn and initiate this care pathway by ensuring the patient is ready for a surgical evaluation and potential emergent procedure. Analysis of Incorrect Options - **Option 1 (Attempt digital rectal stimulation):** This is contraindicated. In a true imperforate anus, there is no patent anal canal to cannulate. Blind instrumentation can cause tissue trauma, create a false passage, or perforate the blind-ending rectal pouch, leading to life-threatening peritonitis. - **Option 2 (Administer glycerin suppository):** This intervention is ineffective and dangerous. A suppository requires a patent anal opening to be inserted and to work. Since the passage is anatomically blocked, the suppository cannot reach the rectal vault to stimulate evacuation, and its insertion could cause local injury. - **Option 4 (Begin frequent feeding to promote intestinal motility):** This action directly contradicts the management of a complete bowel obstruction. Feeding a patient with a distal blockage will lead to progressive abdominal distension, bilious or feculent vomiting, and a high risk of aspiration pneumonia. It does not promote motility through a non-existent opening and will worsen the patient's condition.References (research sources) - [2]Fetal and Newborn Management of Cloacal Malformations.Research articleJacobs SE, Tiusaba L, Al-Shamaileh T, Bokova E, Russell TL, Ho CP, Varda BK, Pohl HG, Mayhew AC, Gomez-Lobo V, Feng C, Badillo AT, Levitt MA. (2022) · DOI: 10.3390/children9060888 ## 임상 시나리오 Imperforate Anus: Immediate Nursing ManagementPrioritizing NPO and Surgical Referral Imperforate anus is a complete mechanical bowel obstruction. The newborn cannot pass meconium. The immediate priority is to keep the bowel decompressed by maintaining NPO status and inserting a nasogastric tube if ordered. A prompt pediatric surgical consultation is essential. Definitive management requires operative correction, which may involve a staged approach with an initial enterostomy in the neonatal period. CautionNever attempt digital rectal stimulation or insert a suppository. This can cause tissue trauma and will not relieve the obstruction. Do not initiate feedings, as this increases intraluminal pressure and the risk of aspiration and bowel perforation. ## 핵심 개념 - **Imperforate Anus** — A congenital anomaly where the anal opening is absent or abnormally positioned, causing a complete mechanical bowel obstruction. - **NPO** — Nothing by mouth; keeping the gastrointestinal tract empty to prevent aspiration and reduce pressure proximal to an obstruction. - **Meconium** — The dark green, viscous first stool of a newborn, which cannot be passed in cases of imperforate anus. ## 같은 주제 문제 - [A nurse is assessing a newborn with suspected imperforate anus.
