Answer 9

True

Question 10

T/F: ‘Bat wings’ or ‘butterfly’ patterns can sometimes be seen on patients with interstitial lung disease.

c. Atelectasis
d. Bacterial Pneumonia

Answer 17

b. ARDS

Question 18

Acute injury to alveolar epithelial lining cells is a key feature of ARDS.

I. Central venous pressure
II. Pulmonary artery catheter

all of the above

Question 20

If dense substances appear light or white, they are:

a. radiopaque
b. radiolucent

Answer 20

a. radiopaque

Question 21

If low density substances appear dark or black, they are:

a. radiopaque
b. radiolucent

Answer 21

b. radiolucent

Question 22

______ images appear more white.

a. overexposed
b. underexposed

Answer 22

b. underexposed

Question 23

_______ images appear more black.

a. overexposed
b. underexposed

Answer 23

a. overexposed

Question 24

T/F: Treatment should never be delayed while images are produced and interpreted.

Answer 24

True

Question 25

Most routine type of imaging:

a. Anteroposterior (AP) view
b. Posteroanterior (PA) view

Answer 25

b. Posteroanterior (PA) view

Question 26

Which radiographic view is commonly taken for portable imaging on bed bound patients (ICU)?

a. Anteroposterior (AP) view
b. Posteroanterior (PA) view

Answer 26

a. Anteroposterior (AP) view

Question 27

t/f: in both left lateral and PA projections, the heart is closer to the film.

Answer 27

True

This minimizes cardiac magnification, AP xrays have more magnification artifact due to closer proximity

Question 28

Lateral decubitus view is primarily used to:

Answer 28

I. see if pleural fluid is present
II. identify pneumothorax

I, II ONLY

a. unaffected, affected
