Introduction
This comprehensive assessment is designed to evaluate your readiness for the HESI Radiology Exit Examination. It
measures your foundational knowledge, clinical reasoning, and applied skills across all core areas of radiologic
technology. The exam consists of 200 multiple-choice questions divided into two sections, each featuring scenario-
based questions that emphasize critical thinking and real-world decision-making. Successful completion requires
integration of theoretical understanding with practical application, ensuring you are prepared to deliver safe, effective,
and compassionate patient care. This document serves as a reliable study resource, providing verified answers with
detailed rationales to reinforce your learning and confidence.
,SECTION ONE: QUESTIONS 1-100
Question 1
A radiologic technologist is preparing to perform a portable chest X-ray on a patient in the intensive care unit. The
patient is on a mechanical ventilator with multiple IV lines and monitoring equipment. Which of the following
actions is MOST important to ensure patient safety during this procedure?
A. Ensuring the patient's family members are present for support
B. Positioning the image receptor as close to the patient's back as possible
C. Verifying all necessary equipment is unplugged before the exposure
D. Checking that the patient's identity is confirmed using two identifiers
🟢 D. Checking that the patient's identity is confirmed using two identifiers
🔴 Explanation: Patient identification is the foundational step in ensuring the correct procedure is performed on the
correct patient. The Joint Commission requires two patient identifiers (e.g., name and date of birth) before any
procedure. While other actions are important for image quality and safety, identity verification is the most critical
safety measure.
Question 2
What is the primary purpose of using a grid in radiography?
A. To increase the contrast of the radiographic image
B. To absorb scattered radiation before it reaches the image receptor
,C. To magnify small anatomical structures for better visualization
D. To reduce the overall radiation dose to the patient
🟢 B. To absorb scattered radiation before it reaches the image receptor
🔴 Explanation: A grid is placed between the patient and the image receptor to absorb scattered radiation, which
improves image contrast by reducing the fog caused by scatter. Although grids do improve image quality, they do
not reduce patient dose; in fact, they require increased technique.
Question 3
A patient scheduled for an intravenous pyelogram (IVP) reports a history of severe allergic reaction to shellfish. What
is the MOST appropriate initial action by the technologist?
A. Proceed with the exam using a low-osmolar contrast agent
B. Cancel the exam and notify the referring physician immediately
C. Administer prophylactic antihistamines as per department protocol
D. Inform the radiologist and obtain a thorough allergy history
🟢 D. Inform the radiologist and obtain a thorough allergy history
🔴 Explanation: A history of shellfish allergy does not automatically indicate a contraindication to iodinated contrast,
though there is a cross-reactivity concern. The technologist should inform the radiologist, who will determine if
premedication is needed or if alternative imaging is appropriate. The technologist should not independently cancel
or medicate the patient.
, Question 4
Which of the following positions would best demonstrate the right anterior oblique (RAO) projection of the
sternum?
A. Patient prone with the left side elevated 15-20 degrees
B. Patient supine with the right side elevated 15-20 degrees
C. Patient prone with the right side elevated 15-20 degrees
D. Patient supine with the left side elevated 15-20 degrees
🟢 C. Patient prone with the right side elevated 15-20 degrees
🔴 Explanation: The RAO projection of the sternum requires the patient to be prone (or upright) with the right side
rotated toward the image receptor, typically 15-20 degrees. This positioning brings the sternum away from the spine
and into the heart shadow, improving visualization.
Question 5
What is the maximum permissible dose (MPD) for a radiologic technologist per year according to the NCRP?
A. 10 mSv
B. 50 mSv
C. 100 mSv
D. 500 mSv
🟢 B. 50 mSv
