MULTIPLE CHOICE
1. WHICH OF THE FOLLOWING BEST DESCRIBES THE PRIMARY PURPOSE OF DIAGNOSTIC
RADIOGRAPHY?
A. TO TREAT DISEASES USING IONIZING RADIATION
B. TO PRODUCE IMAGES OF INTERNAL STRUCTURES FOR DIAGNOSIS
C. TO MONITOR PATIENT VITAL SIGNS
D. TO STERILIZE MEDICAL EQUIPMENT
ANSWER: B
RATIONALE: DIAGNOSTIC RADIOGRAPHY’S MAIN PURPOSE IS TO PRODUCE IMAGES OF
INTERNAL BODY STRUCTURES, ALLOWING PHYSICIANS TO DETECT AND DIAGNOSE
ABNORMALITIES.
A: TREATING DISEASES WITH RADIATION IS THE ROLE OF RADIATION THERAPY, NOT
DIAGNOSTIC RADIOGRAPHY.
C: MONITORING VITAL SIGNS IS PERFORMED USING EQUIPMENT SUCH AS CARDIAC
MONITORS, NOT RADIOGRAPHIC IMAGING.
D: STERILIZATION OF EQUIPMENT IS DONE THROUGH CHEMICAL, HEAT, OR GAS METHODS,
NOT DIAGNOSTIC X-RAYS.
2. WHAT IS THE PRIMARY SOURCE OF IONIZING RADIATION IN MEDICAL IMAGING?
A. MRI SCANNER
B. X-RAY TUBE
C. ULTRASOUND TRANSDUCER
D. PET SCANNER
ANSWER: B
, RATIONALE: THE X-RAY TUBE GENERATES IONIZING RADIATION USED IN DIAGNOSTIC
RADIOGRAPHY.
A: MRI SCANNERS USE MAGNETIC FIELDS AND RADIOFREQUENCY WAVES, WHICH ARE NON-
IONIZING.
C: ULTRASOUND TRANSDUCERS USE HIGH-FREQUENCY SOUND WAVES, NOT RADIATION.
D: PET SCANNERS DETECT RADIATION FROM INJECTED RADIOACTIVE TRACERS; THEY DO
NOT GENERATE RADIATION IN A TUBE LIKE X-RAY SYSTEMS.
3. HOW DOES THE ALARA PRINCIPLE GUIDE RADIOLOGIC PRACTICE?
A. MAXIMIZING IMAGE QUALITY REGARDLESS OF DOSE
B. MINIMIZING RADIATION EXPOSURE WHILE ACHIEVING DIAGNOSTIC QUALITY
C. LIMITING PATIENT INTERACTION TO REDUCE INFECTION
D. INCREASING EXPOSURE TIME FOR BETTER PENETRATION
ANSWER: B
RATIONALE: ALARA (“AS LOW AS REASONABLY ACHIEVABLE”) ENSURES RADIATION
EXPOSURE IS KEPT AS LOW AS POSSIBLE WHILE STILL OBTAINING DIAGNOSTIC -QUALITY
IMAGES.
A: IMAGE QUALITY SHOULD NOT BE PRIORITIZED AT THE EXPENSE OF UNNECESSARY
RADIATION DOSE.
C: INFECTION CONTROL IS IMPORTANT BUT IS NOT THE PURPOSE OF ALARA.
D: INCREASING EXPOSURE TIME RAISES PATIENT DOSE AND CONTRADICTS ALARA
PRINCIPLES.
4. A RADIOLOGIC TECHNOLOGIST IS PREPARING TO IMAGE A PATIENT WITH A SUSPECTED
FRACTURE. WHICH SAFETY MEASURE IS MOST IMPORTANT?
A. USING THE FASTEST IMAGING SPEED
B. ENSURING PROPER PATIENT SHIELDING AND POSITIONING
C. INCREASING EXPOSURE TO REDUCE REPEAT IMAGES
D. ALLOWING THE PATIENT TO MOVE DURING IMAGING
