RADR Unit 2 Exam Review (350 Questions) – Chest Imaging, Abdomen Positioning, Anatomy & Exposure Factors | 2026 – Radiologic Technology

This document contains an extensive set of approximately 350 exam-style questions and verified answers for RADR Unit 2, focusing on chest and abdominal imaging, anatomical landmarks, and radiographic positioning principles. It covers essential topics such as the bony thorax, respiratory anatomy, mediastinum structures, lung lobes, and pleural layers, along with key topographical landmarks like the vertebra prominens (C7), inferior angle of the scapula (T7), and iliac crest (L4–L5). The Q&A format supports efficient memorization and thorough exam preparation. The material provides in-depth coverage of radiographic positioning and technique, including PA, AP, lateral, oblique, and decubitus chest projections, as well as abdominal imaging such as KUB, erect abdomen, and acute abdominal series (AAS). It explains central ray (CR) placement, SID requirements (72" for chest, 40" for abdomen), exposure factors (kVp ranges), and positioning criteria such as rotation, inspiration, and anatomical inclusion. The content across pages 5–18 clearly outlines these positioning standards and imaging techniques, which are critical for producing diagnostic-quality radiographs. Additionally, the document explores pathology recognition and clinical indications, including conditions such as pneumonia, pneumothorax, pleural effusion, COPD, ascites, ileus, bowel obstruction, and pneumoperitoneum. It also integrates abdominal anatomy (quadrants, organs, peritoneal structures), respiratory physiology, and motion control techniques, making it a complete and high-yield study resource for both theory and clinical application. This resource is ideal for students enrolled in Radiologic Technology, Diagnostic Medical Imaging, or Radiography programs. It is particularly useful for courses such as RADR – Radiographic Procedures, Chest and Abdomen Imaging, or Positioning and Anatomy offered at universities, community colleges, and allied health institutions. It is especially beneficial for first-year radiography students preparing for unit exams, lab practicals, or competency assessments. The content aligns closely with standard textbooks such as Merrill’s Atlas of Radiographic Positioning and Procedures by Jeannean Hall Rollins and Radiographic Imaging and Exposure by Terri L. Fauber, making it an excellent supplementary study guide for mastering radiographic positioning, anatomy, and imaging techniques.
