ARRT Cardiac Interventional Radiography Examination Practice Test
Cardiac interventional radiography practice focuses on imaging and patient-care decisions during catheter-based cardiac procedures. Topics sampled in this question bank include iodinated contrast safety, coronary angiography, fluoroscopic image quality, invasive pressure measurement, sterile catheter preparation, vascular access equipment, and basic cardiac anatomy.
Exam overview
About the ARRT Cardiac Interventional Radiography Examination Exam
Procedural work requires recognizing changes in a patient's condition and relaying relevant findings promptly to the team. Contrast planning involves clarifying medical history and considering factors such as renal function and metformin use. Image acquisition decisions include collimating to the area of interest and accounting for respiratory motion. Invasive pressure measurements depend on correctly leveling the transducer to the patient's reference point. Safe preparation includes removing air from contrast-delivery equipment and maintaining sterile technique around intravascular catheters. Questions also address the function of an arterial introducer sheath and the anatomy of the chambers and valves. These concepts connect equipment setup and imaging choices with patient safety and the quality of information available to the procedural team.
Sample Practice Questions

When preparing a patient for a procedure using iodinated contrast, which history item is particularly important to clarify because it may affect the risk of kidney injury?
Show answer
Correct answer: AVolume depletion can impair renal perfusion and is a relevant risk factor when considering contrast-associated kidney injury. The care team evaluates the complete clinical context and follows appropriate hydration and contrast-use protocols.
A patient reports new chest discomfort during coronary angiography. Which information should be communicated promptly to the procedural team?
Show answer
Correct answer: APromptly reporting the symptom's timing and features, together with associated vital-sign or ECG changes, helps the team assess potential ischemia or other complications. Unrelated administrative details do not aid immediate evaluation.
When a pressure transducer is being used to measure cardiac pressures, why should it be leveled to the patient's reference level?
Show answer
Correct answer: AA fluid-filled pressure system can show a falsely high or low value if the transducer is above or below the reference level. Proper leveling helps ensure that recorded pressures reflect the intended anatomical reference.
A patient with diabetes taking metformin is scheduled for an iodinated contrast study. Which factor is especially important to assess when planning contrast administration?
Show answer
Correct answer: ARenal function is important in assessing the risk of contrast-associated kidney injury and guiding patient-specific management. Medication decisions, including those involving metformin, should follow current institutional policy and the patient's clinical circumstances.
During fluoroscopy, what is the main purpose of collimating the x-ray beam to the region of clinical interest?
Show answer
Correct answer: ACollimation restricts the x-ray field to the anatomy needed for the procedure. This limits unnecessary irradiation and reduces scatter, while the field should still be large enough to show the required anatomy.
A coronary angiography image is acquired with the patient unable to suspend respiration. What is a likely effect of respiratory motion on the image?
Show answer
Correct answer: ARespiratory motion can shift the heart and coronary arteries during image acquisition, producing blur or misregistration. When clinically feasible, coordinated breath-holding can reduce this motion.
Which measure is most appropriate for reducing the risk of air embolism when preparing an intravascular contrast-delivery system?
Show answer
Correct answer: ACareful priming removes air from the tubing and connections before they are used intravascularly. A closed, properly prepared system helps prevent air from entering the circulation.

Preparation tips
- Review how renal function and metformin use inform planning for iodinated contrast, and distinguish a history item that needs clarification from a confirmed contraindication.
- Practice explaining how transducer leveling affects invasive pressure readings, and identify the patient reference level used in the measurement setup.
- For coronary angiography scenarios, connect collimation and respiratory motion with the resulting field of view and image sharpness.
- Rehearse sterile preparation steps for intravascular contrast delivery, including air removal, and be able to state the purpose of an arterial introducer sheath.
- Refresh chamber and valve anatomy, then practice identifying new symptoms during a procedure that warrant prompt communication to the team.
