RADR 1409 Exam 4 Review (150 Questions) – Contrast Media, Imaging Procedures, GI Studies & Radiographic Modalities | 2026 – Radiologic Technology

This document contains a comprehensive set of approximately 150 exam-style questions and answers designed for RADR 1409 Exam 4, focusing on contrast media, imaging procedures, and advanced radiographic concepts. It covers key topics such as types of contrast agents (barium sulfate, iodinated media, air/gas), their clinical uses, contraindications, and preparation protocols for gastrointestinal (GI) studies. The structured Q&A format allows for efficient studying, helping students reinforce critical knowledge for exams and clinical application. The material also provides in-depth explanations of diagnostic imaging procedures including Upper GI (UGI), barium enemas, enteroclysis, cystography, myelography, ERCP, and IVU/IVP studies. It highlights patient preparation techniques such as fasting, bowel cleansing, and contrast sequencing, along with post-procedure care and potential complications like contrast reactions and nephrotoxicity. Concepts such as osmolality, viscosity, and lab value monitoring (BUN and creatinine) are also emphasized to ensure safe contrast administration. Additionally, the document explores hospital and clinical environments including ICU, CCU, NICU, and PACU, along with mobile radiography considerations and patient care around medical devices such as NG tubes, PICC lines, chest tubes, and ventilators. It also includes surgical protocols, sterile field guidelines, angiography techniques (Seldinger method), and an overview of imaging modalities such as CT, MRI, ultrasound, and nuclear medicine. This resource is ideal for students enrolled in Radiologic Technology, Diagnostic Medical Imaging, or Allied Health programs. It is particularly useful for courses such as RADR 1409 – Patient Care in Radiography, Radiographic Procedures II, or Contrast Media and Imaging Techniques offered at universities, community colleges, and healthcare training institutions. It is especially beneficial for first-year and second-year radiography students preparing for advanced exams or clinical evaluations. The content aligns closely with standard textbooks such as Patient Care in Radiography: With an Introduction to Medical Imaging by Mary Alice Statkiewicz Sherer and Radiographic Imaging and Exposure by Terri L. Fauber, making it an excellent supplementary study guide for both theoretical understanding and clinical practice.
