Positioning chapter 2 chest situations

A routine chest series indicates a possible mass beneath a patient's right clavicle. The PA and lateral projections are inconclusive. What additional projection(s) could be taken to rule out this condition

AP Lordotic

A young child enters the emergency room with a possible foreign body in one of the bronchi of the lung. The foreign body, a peanut, cannot be seen on the PA and lateral projections of the chest projection. Which additional projections could the technologist perform to locate the foreign body?

AP and lateral upper airway

A patient with a possible neoplasm in the right lung apex comes to the radiology department for a chest exam. The PA and lateral projections do not clearly demonstrate the neoplasm because of superimposition of the clavicle over the apex. The patient is unable to stand or sit erect. Which additional projection can be taken to demonstrate the neoplasm clearly and to eliminate the superimposition of the clavicle and the left lung apex?

AP semiaxial projection 15-20 degree angle cephalad to project the clavicles above the apices

PA and left lateral projections demonstrate a suspicious region in the left lung. The radiologist orders an oblique projection that will best demonstrate or "elongate" the left lung. Which specific oblique projections will best elongate the left lung?

Both LPO and RAO

A patient comes to the radiology department for a presurgical chest examination The clinical history indicates a possible stius inversus of the thorax. Which positioning step or action must be taken to preform a successful chest examination?

Correct side markers

A patient with a clinical history of advanced emphysema comes to the radiology department for a chest x-ray. AEC will not be used. How should the tech alter the manual exposure settings for this patient?

Decrease the kV moderately (--)

A patient with a history of pleurisy comes to the radiology department. Which of the following radiographic series should be preformed?

Erect PA and lateral chest

A patient with severe pleural effusion comes to the radiology department for a chest x-ray. Automatic exposure control (AEC) will not be used. How should the technologist alter the manual exposure setting for this patient?

Increase the kV slightly (+)

A patient with a history of pulmonary edema comes to the radiology department and is unable to stand. The physician suspects fluid in the left lung. Which specific projection should be used to confirm the diagnosis?

Left lateral decub

A patient has a possible small penumothorax. Routine chest projections (PA and lateral) fail to show the pneumothorax conclusively. Which additional projections could be taken to rule out this condition

PA inspiration/expiration or lateral decub ***AP chest?

A patient enters the emergency room with a possible hemothorax in the right lung caused by a motor vehicle accident. The patient is unable to stand or sit erect. Which specific projection would be best?

Right lateral decubitus
