RADR 1409 Exam 1 Review (300 Questions) – X-Ray Basics, Radiation Protection, Ethics & Patient Care | 2026 – Radiologic Technology

This document contains a comprehensive set of approximately 300 exam-style questions and verified answers designed for Exam 1 in RADR 1409. It covers foundational radiography concepts including x-ray production, electromagnetic properties, exposure factors (kVp, mA, mAs, SID), and image quality principles such as contrast, distortion, and detail. The material is presented in a clear Q&A format, making it highly effective for active recall, quick revision, and mastering essential concepts required for early radiography coursework. In addition to technical imaging concepts, the document provides in-depth coverage of radiation protection, biological effects of radiation, and safety principles such as ALARA, dosimetry, and shielding. It also explores patient care topics including communication, cultural considerations, stages of grief, and age-specific care. Ethical and legal principles are thoroughly addressed, including HIPAA, informed consent, malpractice, patient rights, and professional standards, making this resource both clinically relevant and academically comprehensive. The document further includes healthcare system structures (HMO, PPO, Medicare, Medicaid), hospital organization, professional roles, and accreditation bodies, along with historical contributors to radiology such as Roentgen and Coolidge. These topics ensure a well-rounded understanding of both the scientific and professional aspects of radiologic technology. This material is ideal for students enrolled in Radiologic Technology, Diagnostic Medical Imaging, or Radiography programs. It is particularly suited for courses such as RADR 1409 – Introduction to Radiography, Patient Care in Radiology, or Radiographic Procedures I offered at universities, community colleges, and allied health institutions. It is especially beneficial for first-year radiography students preparing for initial exams, foundational assessments, or competency evaluations. The content aligns closely with standard textbooks such as Radiography Essentials for Limited Practice by Bruce W. Long, Jeannean Hall Rollins, and Barbara J. Smith, as well as Radiographic Imaging and Exposure by Terri L. Fauber, making it an excellent supplementary study guide.
