Chest

Question 1

if you want to rule out a hemothorax, how do you position the patient?

Answer 1

R/L lateral decubitus

Question 2

what kVp range is typical for chest projections?

Answer 2

120 kVp

Question 3

how long should you wait before making the exposure with the patient in the decubitus position?

Answer 3

5 minutes

Question 4

pulmonary edema

Answer 4

replacement of air with fluid in the lung interstitium and alveoli

Question 5

what is the preferred general position for a chest x-ray and why?

Answer 5

upright and PA, prevents magnification of the heart and pulls the diaphragm down

Question 6

emphysema

Answer 6

obstructive airway changes leading to an increased volume of air in the lungs

Question 7

for the lateral chest, which plane is parallel to IR?

Answer 7

midsagittal

Question 8

pneumonia

Answer 8

acute infection in the lung parychema

Question 9

which decubitus positions could we use if the patient is unable to roll onto their side?

Answer 9

R/L ventral/ dorsal decubitus

Question 10

pleural effusion

Answer 10

collection of fluid in the pleural cavity

Question 11

cystic fibrosis

Answer 11

widespread dysfunction of the exocrine glands, abnormal secretion of sweat and saliva, and accumulation of mucus in the lungs

Question 12

chronic obstructive pulmonary disease (COPD)

Answer 12

chronic condition of persistent obstruction of bronchial airflow

Question 13

how many posterior ribs must be visible above the diaphragm on a PA chest to ensure proper inspiration?

Answer 13

10

Question 14

how many degrees do you rotate the patient for a PA oblique chest?

Answer 14

45 degrees

Question 15

what would you do if the patient was unable to perform the lordotic position?

Answer 15

AP axial

Question 16

for PA oblique projections of the chest, which is the side of interest?

Answer 16

side farther from the IR

Question 17

for AP oblique projections of the chest, which is the side of interest?

Answer 17

side closer to the IR

Question 18

metastasis

Answer 18

transfer of a cancerous lesion from one area to another

Question 19

where does the esophagus lie in relation to the trachea?

Answer 19

posterior

Question 20

where is oxygen and carbon dioxide exhanged?

Answer 20

by diffusion within the walls of the alveoli

Question 21

what is the space between the two pleural walls called?

Answer 21

pleural cavity

Question 22

how many lobes does each lung have?

Answer 22

left = 2
right = 3

Question 23

why do we use a minimum of 72” SID for chest x-rays?

Answer 23

minimizes magnification of the heart

Question 24

why do we use the decubitus position for chest imaging?

Answer 24

it allows fluid to settle and air to rise if checking for pleural effusion or pneumothorax

Question 25

pneumothorax

Answer 25

accumulation of air in the pleural cavity resulting in collapsed lung

Question 26

bronchitis

Answer 26

inflammation of the bronchi

Question 27

hemothorax

Answer 27

accumulation of blood in the pleural cavity

Question 28

why do we perform soft tissue neck x-ray?

Answer 28

demonstrate foreign bodies, swelling, masses, and fractures of larynx and hyoid bone

Question 29

for the lateral chest, how should the arms be positioned?

Answer 29

extend the arms upwards, outside collimation light

Question 30

what are the breathing instructions for a chest x-ray and why?

Answer 30

deep breath and hold it, diaphragm moves inferiorly, and fills air with lungs

Question 31

thymus gland

Answer 31

primary control of the lymphatic system

Question 32

why is the left lateral chest position preferred over the right?

Answer 32

it places the heart closer to the IR, reducing magnification

Question 33

what separates the thoracic/abdominal cavity?

Answer 33

diaphragm

Question 34

aspiration

Answer 34

inspiration of foreign body into the airway

Question 35

where should the top of the IR be positioned for a PA oblique chest?

Answer 35

1.5-2 inches above C7

Question 36

why is the right lung shorter than the left?

Answer 36

the liver sits higher

Question 37

atelectasis

Answer 37

collapse of all of part of the lung

Question 38

if you want to rule out a pneumothorax, how do you position the patient?

Answer 38

R or L lateral decubitus

Question 39

the double walled serous membrane sac that encloses the lung

Answer 39

pleura
