X-Ray Certification Patient Care and Positioning 5

Question 1

The AP axial projection of the coccyx requires a central ray angle of:

Accepted Answer

10 degrees caudad

Answer

A 10-degree caudad (toward the feet) angle is used for the AP coccyx to reduce foreshortening of this curved structure.

Question 2

Which radiographic position places the patient's left side against the IR for an upright chest?

Accepted Answer

Left lateral

Answer

The left lateral chest projection places the patient's left side against the IR to minimize heart magnification since the heart is left-sided.

Question 3

A patient with a broken arm in a posterior splint needs a forearm radiograph. The technologist should:

Accepted Answer

Position the arm with the splint in place as close to standard as safely possible

Answer

The technologist should work around immobilization devices and position as close to standard projections as safely possible without removing the splint.

Question 4

When instructing a patient on proper breathing for an upper GI series, the technologist should tell the patient to:

Accepted Answer

Hold breath on expiration or breathe shallowly as directed during each exposure

Answer

For upper GI fluoroscopy, patients typically suspend respiration on expiration or use shallow breathing to reduce motion and improve visualization of the stomach.

Question 5

To verify correct central ray centering for a PA wrist radiograph, the CR should be directed to:

Accepted Answer

The midcarpal area (midpoint of the carpals)

Answer

The central ray is directed to the midcarpal area to include the distal radius/ulna and all carpal bones on a PA wrist projection.
