Sample Questions and Answers

Question 1.

During a routine quality-control check, an operator notices that an X-ray image has reduced contrast even though positioning and exposure settings appear appropriate. Which factor could contribute to this problem?

A. Excessive scatter radiation reaching the image receptor

B. Correct alignment of the patient with the central ray

C. Proper collimation to the area of interest

D. Appropriate selection of the image receptor

Correct Answer: A. 

Explanation:

Scatter radiation can reduce radiographic contrast by adding unwanted exposure to the image receptor. This additional signal makes differences between adjacent anatomical structures less distinct. Collimation helps reduce the volume of tissue irradiated and therefore limits scatter production. Appropriate positioning and image receptor selection also support image quality but do not explain the contrast loss described. The operator should review the examination setup and follow the approved technique protocol. If a grid is indicated, its correct selection and alignment should also be verified to help control scatter reaching the receptor.

Question 2.

An operator discovers that the exposure switch on an X-ray unit sometimes continues producing an exposure after the operator attempts to release it. What is the safest action?

A. Continue using the unit at a lower mAs setting.

B. Hold the switch more lightly during the next examination.

C. Stop using the equipment and report the malfunction for inspection by qualified service personnel.

D. Complete all scheduled examinations before reporting the issue.

Correct Answer: C. 

Explanation:

An exposure switch that does not reliably terminate an exposure presents a serious equipment-safety concern. Continued irradiation can result in unnecessary patient exposure and may compromise safe operation. The operator should discontinue use of the affected equipment, follow the facility’s equipment-failure procedure, and notify the appropriate supervisor or service personnel. Lowering the exposure setting does not correct the underlying electrical or control fault. The unit should return to clinical use only after the required inspection, repair, and safety checks have been completed according to facility policy.

Question 3.

A patient arrives for an X-ray examination, but the name on the wristband does not match the name on the imaging request. What should the operator do first?

A. Use the name printed on the imaging request without further checking.

B. Ask another patient in the waiting area to confirm the identity.

C. Perform the examination and correct the record afterward.

D. Pause the examination and resolve the identity discrepancy using the approved patient-identification procedure.

Correct Answer: D. 

Explanation:

Patient identification must be established before an examination proceeds. A mismatch between the wristband and imaging request creates a risk of performing the wrong examination or attaching images to the wrong medical record. The operator should stop and use the facility’s approved identification process, involving the appropriate clinical staff or referring department when necessary. The examination should not proceed until the discrepancy has been resolved and the order is confirmed. Correcting the record after exposure does not eliminate the initial safety risk. Accurate identification protects patients and supports reliable documentation.

Question 4.

A digital radiography system repeatedly displays a detector communication error before an exposure can be completed. What is the most appropriate response?

A. Follow the equipment troubleshooting procedure and report the fault if it persists before continuing clinical imaging.

B. Increase the kVp to overcome the communication problem.

C. Repeat exposures until the detector begins responding normally.

D. Change the patient’s examination details to bypass the error.

Correct Answer: A. 

Explanation:

A detector communication error may indicate a connection problem, software fault, detector malfunction, or system configuration issue. The operator should follow the manufacturer’s instructions and the facility’s approved troubleshooting process. If the error persists, the equipment should be taken out of service as required and reported to qualified support personnel. Increasing kVp cannot repair a communication failure, and unnecessary repeat exposures can increase patient radiation dose without producing a usable image. Patient records must remain accurate throughout troubleshooting. Clinical imaging should resume only when the system is functioning safely and reliably.

Question 5.

During a mobile X-ray examination, a patient becomes dizzy while being repositioned and appears unable to maintain balance. What should the operator do?

A. Finish positioning quickly before the patient becomes more uncomfortable.

B. Stop the movement, help prevent a fall, and seek appropriate clinical assistance.

C. Ask the patient to stand unsupported until the dizziness passes.

D. Proceed with the exposure while another staff member holds the patient upright.

Correct Answer: B. 

Explanation:

Dizziness during repositioning creates an immediate risk of falling and injury. The operator should stop the movement, help the patient remain safe within the operator’s training and facility procedures, and obtain clinical assistance when needed. The patient’s condition should be reassessed before any further positioning or imaging takes place. Continuing simply to complete the examination can worsen the situation. An alternative position or transfer method may be considered when clinically appropriate and authorized. Patient safety takes priority over completing the planned projection without delay.
