Safety Question-Reg Review

A nonpregnant relative to a 2-year-old child volunteers to help restrain the child while AP and lateral radiographs are obtained in the upright position. This person should be provided with:

•  appropriate protective apparel.

• a thermoluminescent dosimeter.

• a self-reading pocket dosimeter.

• an OSL badge.

Which of the following devices should be used to reduce exposure to the mammary glands during a juvenile scoliosis examination?

• Thyroid shield

• Breast shields

• Shadow shield

• Shaped contact shield

Which of the following is essential for the protection of the radiographer who is performing a mobile radiographic examination?

1. Protective lead apron

2. Primary protective barrier

3. Six-foot exposure cord

• 1 and 3 only

• 1 and 2 only

•  2 and 3 only

• 1, 2, and 3

Entrance exposure dose is the same as:

• bone marrow dose.

•  gonadal dose.

• skin dose.

• organ dose.

The primary beam should never be directed toward the:

• upright wall Bucky.

• control booth barrier.

• upright radiographic table top.

• recumbent radiographic table top.

A diagnostic lateral radiograph of the paranasal sinuses has been obtained with the following technical factors: 66 kVp, 20 mAs. To significantly reduce patient exposure while maintaining overall average receptor exposure, which of the following technical factors should be used?

• 76 kVp, 10 mAs

• 70 kVp, 5 mAs

•  68 kVp, 15 mAs

• 60 kVp, 25 mAs

Which of the following will not provide radiation protection for the radiographer?

•  Bucky slot shielding device

• OSL dosimeter

• Lead apron of 0.5 mm lead equivalent

• Sliding panel of 0.25 mm lead equivalent

Which of the following methods and/or techniques will reduce the radiographer's radiation exposure?

1. Collimation of the radiographic beam margins to less than the size of the image receptor

2. Use of higher kVp, lower mAs techniques

3. Filtration of the radiographic beam

•  1 only

• 2 only

• 1, 2, and 3

• 3 only

The purpose for establishing annual limits for occupationally exposed individuals is to:

• control the maximum risk to a person in any year.

• determine the minimum risk that an individual should take in any given year.

• avoid the need for initiating federal legislation to police the medical radiation industry.

• prevent the normal occurrence of job-related genetic damage from occurring.

The practice of intermittent fluoroscopy:

1. prolongs the life of the fluoroscopic tube.

2. decreases patient dose.

3. blurs the fluoroscopic image.

• 1 and 2 only

• 1 and 3 only

•  2 and 3 only

•  1, 2, and 3
