Exercise D (2)

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

A locldie

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

Decrease the kV moderately ()

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

Erect PA and lateral

Situation: patient severe pleural effusion mes 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 settings for this patient?

Increase the kV slightly (+).

Situation: 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? (More than one oblique projection will accomplish this goal.)

LPG BAO

Situation: A patient comes to the radiology department for a presurgical chest examination. The clinical history indicates a possible situs inversus of the thorax (transposition of structures within the thorax). Which positioning step or action must be taken to perform a successful chest examination?

A radiograph of a PA view of the joint is closer to the midline than of the chest shows that the sternoclavicular (SC) joints are not the same distance from the spine. What is the positioning error?

Poor rotation

A radiograph of a PA projection of the chest shows only seven posterior ribs above the diaphragm. What caused this problem, and how could it be prevented on the repeat exposures?

The lungs are underinflated. Explain to the patient the need for a deep inspiration, and take the exposure on the second deep inspiration.

A radiograph of a lateral projection of the chest shows the posterior ribs and costophrenic angles are separated more than inch, or 1 cm, indicating excessive rotation. Describe a possible method for determining the direction of rotation. orA

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

projections could be taken to rule out this condition? Routine chest projections (PA and lateral) fail to show the pneumothorax conclusively. Which additional Situation: A patient has a possible small pneumothorax. laleal dlibs Ar rut

A radiograph of a PA and a left lateral projection of the chest show the mediastinum of the chest is under-penetrated. The technologist used the following factors for the radiograph: 72-inch(183-cm) SID, an upright Bucky, a full-inspiration exposure, 75-kV and 600-mA, and a 1/60-second exposure time.Which of these factors is the most likely cause of the problem? Briefly explain.

75 kV. 110 to 125 kV is necessary to produce a diagnostic image of the chest

Situation: A patient enters the emergency room with a possible hemothorax in the right lung caused by a motor vehicle accident (MVA). The patient is unable to stand or sit erect. Which specific projection would best demonstrate this condition, and why?

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