RADT 1030 Workbook practice part 3

where is the CR placed for a lateral projection of the upper airway?

C6-C7 (midway between Adams apple and jugular notch)

which posterior oblique would best demonstrate the left lung?

LPO

Which anterior oblique would best demonstrate the left lung?

RAO

The CR is placed at the level of the _________ vertebrae for a PA chest projection.

T7

an erect PA radiograph aids the patient to achieve full inspiration and helps to prevent ______ and ______ of the pulmonary vessels.

engorgement, hyperemia

How much separation of the posterior ribs on a lateral chest projection indicates excessive rotation from a true lateral position?

greater than 1 cm

which specific position would be used if a patient were unable to stand but the physician suspected that the patient had fluid in the left lung?

left lateral decubitus (affected side down)

for certain studied of the heart, the _____ anterior oblique requires a rotation of ______.

left, 60 degrees

what are the recommended patient instructions when performing an erect PA chest on a female patient with large pendulous breast?

lift breast up and outward

what is the name of the condition characterized by fluid entering the pleural cavity?

pleaural effusion

what is the name of the condition characterized by free air entering the pleural cavity?

pneumothorax

which specific position would be used if the patient were unable to stand but the physician suspected that the patient had free air in the left pleural cavity?

right lateral decubitus (affected side up)

what circumstances or clinical indications suggest that an AP lordotic projection should be ordered?

rule out calcifications or masses beneath clavicles

The shoulders need to be rolled forward for the PA projection to allow the ________ to move laterally and be clear of the lung field.

scapulae

Careful collimation during a chest radiograph will improve image quality by decreasing _____ radiation to the IR.

scatter

Why should a left lateral be performed unless departmental protocol indicates otherwise?

to better demonstrate the heart

To prevent the clavicles from obscuring the apices on an AP projection of the chest, the central ray should be angled _________ so that it is perpendicular to the ___________

5 degrees, sternum

What position/projection would be used for a patient who is too ill or weak to stand for an AP lordotic projection?

AP semi axial projection with the CR angled 15-20 digress cephlad

Why is a PA Chest preferred over an AP Chest?

Because heart will be closer to IR, thus reducing magnification
