ADN Test 2 QUESTIONS AND ANSWERS 100% CORRECT

EA-Manifestations Correct Answer: Failure to pass suction catheter, NG tube at birth Excessive oral secretions, drooling Vomiting (undigested formula) Abdominal distention Airless, scaphoid abdomen (atresia without fistula) Sonorous (seal like bark cough) Choking with feeding R.distress and cyanosis (if secretions aspirated) EA-Patho Correct Answer: Occurs when the proximal end of the esophagus ends in blind pouch; food unable to enter stomach through esophagus. With TEF: Occurs when connection exists between the esophagus and trachea; may result in reflux of gastric juice after feeding(4-5weeks of pregnancy) Food enters lungs, air enters stomach Cause is unknown Can be with or without TEF (tracheoesophageal fistula) No difference in sex and incidence Nearly half born with EA have other congenital defects (cardiac, GI, CNS) Prematurity Low birth weight EA-Preop Correct Answer: Initial repair includes ligation of the fistula and end-toside anastomosis of the atresia to decrease the severity of stricture formation. G-tube placed Anastomosis, colon interposition, and dilation (expected later) Evaluation and treatment of esophageal motility dysfunction, gastroesophageal reflux, strictures, bronchitis and pneumonia may occur as the child grows EA-Assessment Correct Answer: The infant with TEF is at constant risk of aspiration Assess R.distress immediately after birth Examine for excessive oral secretions, choking, and cyanosis. Difficulty swallowing, regurgitation, vomiting, and unexplained cyanosis after inital feeding of an undiagnosed infant are important findings that requires notification of physician immediately. Measure abdominal distention Continually asses VS and distress (respiratory effort, nasal flaring, retraction, cyanosis) Polyhydramnios (too much amniotic fluid surrounding an unborn infant) Radiopaque catheter Chest x-ray Family assessment of anxiety, fears, concerns, and level of knowledge 3 C's when assessing and managing the child with EA and TEF Correct Answer: Coughing, choking with feedings, and cyanosis Prevent aspiration while neonate is being prepared for surgery TEF-Interventions Correct Answer: Immediately after birth: Radiant warmer Humidified O2 (Relieve R.distress) Preop: NPO IV fluids for hydration Maintaining thermoregulation (radiant warmer) and fluid balance Monitor Temp and VS Accurate I&O records Prevention of aspiration supine, 30*HOB(also reduces reflux) Suction catheter (into proximal pouch and mouth) (nose &mouth to keep area behind pouch empty) G-tube gravity feedings (to allow air to escape from the stomach
