what elevates the diaphragm and abdominal viscera, shortens the lung fields, depresses the sternum, and lowers the ribs and increases their angle near the spine
experation
what depresses the diaphragm and abdominal viscera, lengthens and expands the lung fields, elevates the sternum and pushes it anteriorly, and elevates the ribs

when imaging an obese patient, which landmarks are difficult to palpate
anterior-superior iliac spine (ASIS)
iliac crest
greater trochanter
based on the exterior dimensions of obese patients, larger IR’s are needed to image these patients true or false
false
A PA projection radiograph of the hand should be displayed:
from the perspective of the xray tube and with the fingers pointing upward
who is responsible for obtaining a necessary clinical history when the radiologist is unable to see the patient
radiographer
to dispose of a hypodermic needle properly, it should be:
placed in a puncture- proof container
which of the following technical factors is most important to adjust and increase when imaging an obese patient
kVp
within the OR, who should remove sterile items that are in the way of the radiographer
circulating nurse
to prepare the patient for a radiographic examination of the abdomen, what are the three methods used for cleansing the patient’s bowel
limited diet, laxatives, and enamas
which type of muscle tissue produces peristalis
smooth
which type of muscle tissue comprises skeletal muscle
striated
which pathologic condition requires a decrease in exposure factors from the routine procedure
emphysema
which change in exposure factors should be used to control voluntary motion that is a result of the patient’s age or mental illness
decrease the exposure time
which procedure best reduces the possibility of patient-controlled motion
give understandable instructions to patients
which side marker placement rule applies when performing an AP oblique radiograph of the cervical spine
always mark the side closest to the IR
which piece of information is not required as part of the identification of radiographs
name of the radiographer
what is the primary purpose of collimating to the area of interest
reduces patient exposure
how is radiograph image quality affected when the radiation field is restricted to the area under examination only
increased radiographic contrast resolution
which would cause an artifact on a chest radiographic exam
bra
which change most improves spatial resolution when the sternum is imaged
increasing the SID
most common IR position
lengthwise
which computed radiography accessory houses the image storage phosphors that acquire the latent image
imaging plate
what is the IR in direct digital radiography
solid-state detector
when using a fixed, large IR how is collimation (field size) controlled
manually by the radiographer
reasons to avoid using electronic side marker placement (annotation) in digital imaging include:
increased potential for errors in marking the correct side and increased legal implications
the knowledge, skills, ability, and behaviors that are essential for providing optimal care to defined groups of patients is termed:
age-specific competence
when imaging obese patients, all of the following should be taken into consideration except for:
selecting larger IR sizes and larger collimation settings for DR
the approximate distance from the jugular notch to the pubic symphysis on a patient who is more than 6 feet tall is
24 inches (61 cm)
