INTRODUCTION
The RADR 1311 Midterm Exam assesses foundational knowledge and applied skills
required for entry-level radiologic science students. The examination evaluates
competency in radiographic imaging principles, patient care, radiation protection,
equipment operation, and image evaluation. Questions are presented in multiple-choice
format and include both theoretical concepts and real-world clinical scenarios
encountered in radiology departments. The assessment emphasizes professional decision-
making, safety practices, ethical conduct, and technical accuracy during radiographic
procedures. Candidates must demonstrate the ability to apply radiographic science
principles while maintaining patient safety, regulatory compliance, and high-quality
diagnostic imaging standards.
,SECTION 1
QUESTIONS 1–35
1. Which component of the X-ray tube produces electrons during exposure?
A. Anode
🔴 B. Cathode
C. Rotor
D. Collimator
🔵 Explanation: The cathode contains the filament that emits electrons through
thermionic emission when heated.
2. The primary purpose of lead shielding during radiographic procedures is to:
A. Improve image contrast
🔴 B. Reduce patient radiation exposure
C. Increase beam intensity
D. Improve spatial resolution
🔵 Explanation: Lead shielding absorbs scatter radiation and protects radiosensitive
tissues, thereby reducing unnecessary patient exposure.
3. Which factor primarily controls the penetrating ability of the X-ray beam?
, A. mA
🔴 B. kVp
C. Exposure time
D. SID
🔵 Explanation: Kilovoltage peak (kVp) determines the energy and penetrating power of
the X-ray photons.
4. A radiographer verifies patient identity before an exam. This practice primarily
supports:
A. Image quality
B. Equipment calibration
🔴 C. Patient safety and ethical practice
D. Film processing accuracy
🔵 Explanation: Confirming patient identity prevents medical errors and is a key ethical
and safety requirement in healthcare.
5. The unit used to measure absorbed radiation dose is:
A. Coulomb
B. Roentgen
