Exam 3: Image Analysis of the Chest and Abdomen

A left PA 60-degree oblique chest projection (LAO position) 1)demonstrates the heart shadow to the right of the vertebral column. 2)is obtained to evaluate the size and configuration of the heart shadow. 3)best demonstrates the left lung. 4)demonstrates three times as much lung field on one side of the vertebral column as on the opposite side.

For an AP abdominal projection (lateral decubitus position), 1)the right hemidiaphragm and iliac wing must be included to demonstrate intraperitoneal air. 2)position the shoulders and the ASISs at equal distances from the IR. 3)obtain the exposure on expiration. 4)position the patient's right side adjacent to the imaging table or cart.

On inhalation, the lungs expand 1)vertically. 2)transversely. 3)anteroposteriorly.

For a lateral neonatal or infant chest projection, the 1)neonate or infant remains supine for a cross-table projection. 2)neonate or infant is elevated on a radiolucent sponge for an overhead projection. 3)central ray is centered to the mammary line. 4)humeri are positioned at a 90-degree angle with the chest.

An AP axial chest projection (lordotic position) demonstrates the clavicles superimposing the lung apices and the anterior ribs inferior to their corresponding posterior ribs. How should the positioning setup be changed to obtain an optimal projection?

For an AP chest projection obtained in a neonate or infant who is being ventilated with a high-frequency ventilator, the exposure should be obtained

For a left lateral chest projection with accurate positioning, the 1)SID is set at 40 inches (102 cm). 2)humeri are positioned vertically. 3)shoulders, posterior ribs, and posterior pelvic wings are aligned perpendicular to the image receptor (IR). 4)midsagittal plane is aligned perpendicular to the IR.

For AP projections of the chest performed with a portable x-ray unit, placing the IR lengthwise is not appropriate for which body habitus?

The last rib is attached to the ____ vertebra.

A PA chest projection with poor positioning demonstrates vertical clavicles and the manubrium at the same level as the fifth thoracic vertebra. How was the patient positioned for such an image to be obtained?

To position the scapulae outside the lung field for a PA chest projection, the patient's

The recommended kV range for a child PA chest technique at 72 inches is

Sufficient penetration has been obtained on a PA chest projection when the _____ and posterior ribs are demonstrated through the heart and mediastinal structures.

Voluntary motion can 1)result from patient breathing. 2)be controlled by using a short exposure time. 3)result from peristaltic activity. 4)be identified as sharp bony cortices and blurry gastric and intestinal gases.

For an upright AP abdomen projection, the 1)ASISs are positioned at equal distances from the IR. 2)patient remains in an upright position at least 5 to 20 minutes before the image is obtained. 3)symphysis pubis should be included. 4)patient is instructed to take a deep inspiration before the image is obtained.

An AP axial chest projection (lordotic position) with poor positioning demonstrates the clavicles within the lung apices. How should the positioning setup be adjusted for an optimal image to be obtained? 1)Increase the degree of cephalic central ray angulation. 2)Anteriorly rotate the elbows and shoulders. 3)Arch the patient's back more, increasing the midcoronal plane to IR angle. 4)Position the patient's feet closer to the IR.

A PA chest projection (lateral decubitus position) demonstrates 1)the C6-C7 vertebral bodies without distortion. 2)the manubrium superimposed over the fourth vertebral body. 3)a closed C6-C7 intervertebral disk space. 4)clearly shown C6-C7 spinous processes and laminae.
