ARRT CI Exam 2025/2026 – 120 Questions & Verified Answers | Cardiac Interventional, ABG, Pharmacology, Imaging Protocols

This document provides a complete and verified set of 120 high-yield questions and correct answers for the ARRT Cardiac Interventional (CI) Exam, updated for the 2025/2026 testing cycle. It is meticulously structured to mirror the official ARRT exam format and includes concise, evidence-based explanations ideal for radiologic technologists pursuing post-primary certification in Cardiac Interventional Radiography. Key content areas covered include: Cardiac interventional devices (e.g., pacemakers, intra-aortic balloon pumps, CRT devices) Contrast agents and pharmacology (e.g., diatrizoate, ioversol, fentanyl, midazolam, atropine) ABG interpretation and normal lab ranges (pH, PaO2, HCO3, calcium, sodium, potassium) Interventional imaging protocols and field sizes (SMA, IMA, AP thigh, Coeliac axis) Radiation safety and procedural positioning Complications and emergency response protocols (e.g., cardiac tamponade, hypotension, seizure response) Anticoagulation and reversal agents (e.g., heparin-protamine timing, tranexamic acid) Device materials and manufacturing (e.g., IVC filters from Boston Scientific, Cook Medical, Cordis) Vascular anatomy and pathology (e.g., Takayasu arteritis, embolization strategies) Anesthesia and sedation classifications (ASA), conscious sedation practices This resource is best suited for: ARRT-certified Radiologic Technologists pursuing CI post-primary credentials Imaging students and professionals preparing for the ARRT Cardiac Interventional board exam Cardiac cath lab technologists and interventional radiographers seeking structured exam practice Allied health professionals in vascular and cardiac imaging disciplines Whether you're a practicing RT(R) transitioning into CI certification or reviewing for recertification, this document offers a focused and exam-aligned preparation tool with clearly marked correct answers and clinical accuracy.
