NRSB RRS case studies

NRSB RRS · Put your knowledge to work in context.

The NRSB Registered Radiologic Technologist (RRS) certification is a professional credential for radiographers who want independent, third-party verification of entry-to-practice competence in diagnostic radiography. It suits technologists who have completed formal radiography education and are building or advancing a clinical career, as well as those preparing for state licensure or employer credentialing requirements. The exam samples the full scope of practice rather than one modality: radiation protection and safety, radiographic equipment and image production, patient care and management, procedures and anatomy, image evaluation and quality assurance, and professional ethics and scope of practice. Expect multiple-choice items that mix recall of physics and anatomy with applied judgment - shielding decisions, exposure factor reasoning, patient-communication scenarios, and image-critique questions. The NRSB RRS case studies are 5 cases and about 2,958 words.
