RADR 2401 Final Exam Q&A 400+ Questions – Trauma Positioning Spine Imaging Decubitus Techniques

This document provides a comprehensive collection of over 400 exam-style questions with verified answers for RADR 2401 Final Exam Review, focusing on trauma radiography, positioning techniques, skeletal anatomy, and spine imaging. It is designed as a complete study guide to support both theoretical knowledge and clinical decision-making in emergency and routine radiographic procedures. The material begins with trauma imaging scenarios, including positioning adaptations for non-ambulatory patients, such as using the Scap Y projection for suspected shoulder dislocation and lateral decubitus positions for detecting free intra-abdominal air when patients cannot stand (pages 1–2) . It also covers critical emergency imaging techniques such as dorsal decubitus for abdominal aortic aneurysm evaluation and positioning strategies for pleural effusion and pneumothorax detection. A major portion of the document focuses on skeletal anatomy and positioning, including ribs, sternum, clavicle, and thoracic structures. It explains projection selection (RAO, LAO, LPO), CR angulations, SID recommendations, and breathing techniques to optimize image quality (pages 3–10). It also includes detailed coverage of fracture types (greenstick, flail chest, compression fractures) and pathological conditions such as pectus excavatum, scoliosis, kyphosis, and osteoblastic lesions. The document further explores spine imaging in depth, including cervical, thoracic, lumbar, sacral, and coccyx projections. It covers positioning accuracy, CR centering, obliquity angles, and specialized projections such as swimmer’s lateral, Ferguson method, and hyperflexion/hyperextension views (pages 13–22). Clinical applications include evaluation of herniated discs (MRI), spondylosis, spondylolisthesis, and spinal trauma, along with image evaluation criteria and common positioning errors. Additionally, the content integrates radiation protection principles, including the importance of distance (most effective protection method), shielding, and exposure reduction during mobile radiography. It also includes surgical principles such as asepsis and sterile field management, making it highly relevant for both clinical rotations and exams. The material aligns closely with standard textbooks such as Bontrager’s Textbook of Radiographic Positioning and Related Anatomy, Radiographic Imaging and Exposure by Terri L. Fauber, and Merrill’s Atlas of Radiographic Positioning and Procedures. It is particularly suitable for students enrolled in Radiologic Technology (RADR2401), Medical Imaging, and Radiography programs. This document is ideal for radiography students, medical imaging students, and allied health learners preparing for final exams, clinical competencies, or registry-level examinations such as ARRT.
