TNCC Final Exam Test Open Book Questions and Answers 100% Correct Verified — Trauma Nursing Core Course Study Guide

This is a TNCC (Trauma Nursing Core Course) final exam test prep document formatted as an open-book question-and-answer study guide with 100% correct verified answers. Each item presents a trauma nursing exam question followed by the correct answer, with many entries including the full answer rationale and supporting clinical detail. The document covers the primary, secondary, and tertiary surveys of trauma care; airway and ventilation management including oropharyngeal airway insertion for snoring respirations when no gag reflex is present, bag-mask ventilation after unsuccessful drug-assisted intubation, confirmation of ET tube placement when pulse oximetry drops during transfer, the ramped position for endotracheal tube insertion in bariatric patients, and bedside monitoring with pulse oximetry and capnography to assess oxygenation adequacy and ventilation effectiveness. It addresses shock recognition and staging including compensated shock, early hypovolemic shock indicated by narrowed pulse pressure, neurogenic shock with bradycardia and absent motor function below the level of injury, cardiogenic shock goal-directed therapy, the trauma triad of death (hypothermia, metabolic acidosis, coagulopathy), and serum lactate measurement to gauge end-organ perfusion and tissue hypoxia. Additional content includes spinal cord injury findings such as priapism as a suspicion of complete spinal cord injury, the log-roll maneuver risk of worsening cord damage from unstable spinal injury, American College of Surgeons radiologic spine clearance screening guidelines, and cervical collar removal criteria after physical examination with no radiologic abnormalities on CT. The document also covers thoracic trauma including tension pneumothorax versus simple pneumothorax differentiation by hypotension worsening with inspiration, open chest wound management with nonporous dressing removal, tube thoracostomy chest drainage findings such as fluctuation in the water seal chamber, and complications of positive-pressure ventilation such as worsening pneumothorax. Further topics include traumatic brain injury such as subdural hematoma from bridging vein tearing and in elderly patients on anticoagulants, late signs of increased intracranial pressure including decreased respiratory effort with Cushing response, globe rupture with teardrop-shaped pupil, fat embolism presenting with petechiae and respiratory distress after long bone fractures, crush injury monitoring for dysrhythmias and elevated creatine kinase, electrolyte depletion of calcium after citrated banked blood transfusion, and musculoskeletal injury management including splinting and elevation. The document also addresses burn management with burn center referral criteria and modified Lund and Browder TBSA fluid resuscitation calculations, obstetric trauma with placental abruption findings on cardiotocography at 32 weeks pregnant, pediatric trauma including a 2-year-old fall patient requiring upper back padding with cervical spine stabilization and suspected child maltreatment reporting, geriatric trauma considerations emphasizing medical history, alcohol withdrawal intervention using CIWA-Ar scores, disaster life cycle phases including mitigation, trauma team communication terms including huddle, debriefing, and brief, the MARCH mnemonic for prioritizing care in massive uncontrolled hemorrhage, and disaster triage principles including initiating large-caliber IV access for Ringers lactate in a tornado patient with bilateral femoral fractures. Students can use this document for TNCC final exam preparation, trauma nursing certification review, and self-testing practice by working through the questions and checking responses against the verified answers.
