Question | Answer |
---|---|
The 2 step process in patient preparation? | Artifacts removal from anatomy of interest, and Secure all patient possessions in designated manner and location |
General patient positioning for ambulatory patients receiving wrist, hand, digits, forearm, & elbow radiographs | Seated at end of x-ray table. Affected limb resting on IR placed on tabletop |
General patient positioning for non-ambulatory patients receiving wrist, hand, digits, forearm, or elbow radiographs? | Alter positioning to maximize patient comfort. In w/c or on bed |
Collimation is critical for what reason(s)? | Ethical radiation protection. Optimum image quality |
T/F: Just like in film/screen, it's optimal when using CR or DR to place 2 images per IR. | False. ONE exposure/IR since they are more sensitive to scatter than Film/Screen |
Is IR/Collimation field size is a general procedural guideline? Should you always use the smallest of the recommended IR? | Yes. Yes |
T/F: SID is a standardized part of procedural guidelines? | True |
When SID is not specified under a projection, what is the recommendation for upper limbs? | Merrill’s Atlas recommends 40 inches (102 cm) |
T/F: Digital annotation of L/R markers is acceptable? | False |
Of the following General Procedural Guidelines, what guidelines are missing? General patient position IR/Collimated field size Source–to–image-receptor distance (SID) ID markers Radiation protection | Patient preparation. Patient instructions |
T/F: Shield pediatric patients and patients of reproductive age | True |
Optimum technique is good radiation protection practice, what is another? | Close collimation |
When explaining a position to a patient isn't sufficient, what is a good second option in patient instructions? | Demonstration |
Breathing instructions is/is not required for digit, hand, and wrist radiographs | Is not |
Humerus examinations require the patient to _____ ______ during the exposure | Suspend respiration |
Some facilities allow the collimated field to be aligned ______on the IR to accommodate long bones of the _________ | Diagonally. Humerus |
Humerus radiographs may be obtained with the patient _____ or _____ _____ or in ___ position on the radiographic table or on a stretcher | Standing. Seated upright. Supine |
Humerus examinations require removal of ___ in female patients and a ____provided | Bra. Gown |
T/F: After the patient’s anatomy has been placed in the proper position, it is usually sufficient to remind the patient to hold the position until given further instructions? | True |
T/F: Shielding is required for pediatric patients and patients of reproductive age | True |
Shield patients if they request shielding and when they are ______ at _____? | Seated at XR table |
The 3 types of shielding are? | Contact, shadow, & large part shields |
