X-Ray Error Identification Quiz (Weeks 2/3)

Which of the following best describes "improper centering" in an x-ray image?

• The x-ray beam is not aligned with the area of interest.

• The patient is not holding their breath.

• The exposure time is too long.

• The shielding is placed over the area of interest.

What is the primary purpose of shielding in radiographic imaging?

• To improve image contrast

• To protect patients from unnecessary radiation

• To center the x-ray beam

• To increase exposure

Which of the following is a sign of poor patient positioning in a chest x-ray?

• The clavicles are not equidistant from the spine.

• The image appears too dark.

• The shielding is visible in the image.

• The exposure time is too short.

Which of the following is an example of incorrect exposure settings?

• The image is too light or too dark

• The patient is not centered

• The shielding is missing

• The patient is rotated

A student is reviewing a chest x-ray and notices that the right lung appears larger than the left, and the trachea is shifted. Which error is most likely present?

• Improper centering

• Poor patient positioning

• Incorrect exposure settings

• Inadequate shielding

You observe an x-ray image where the gonadal shielding is placed over the area of interest, obscuring important anatomy. What is the best description of this error?

• Improper centering

• Inadequate shielding practices

• Poor patient positioning

• Incorrect exposure settings

A chest x-ray shows only 6 posterior ribs above the diaphragm. What does this indicate about the patient's inspiration?

• Sufficient inspiration

• Insufficient inspiration

• Overexposure

• Improper centering

If an x-ray image is too dark, which adjustment should be made to the exposure settings for the next attempt?

• Increase the mAs

• Decrease the mAs

• Increase the kVp

• Decrease the SID

A radiograph shows the patient's spine is not centered between the medial ends of the clavicles. What is the most likely cause?

• Improper centering technique

• Inadequate shielding

• Incorrect exposure

• Insufficient inspiration

A student is asked to evaluate a chest x-ray for proper inspiration. What evidence should they use to determine if inspiration was sufficient?

• The number of visible anterior ribs above the diaphragm

• The number of visible posterior ribs above the diaphragm

• The position of the scapulae

• The presence of shielding
