Quiz 3 - CXR & Nutrition Flashcards
Large hilar and paratracheal lymph nodes:
a. asbestosis
b. sign of end-stage pulmonary fibrosis
c. sarcoidosis
d. bronchiectasis
c. sarcoidosis
Calcified pleural or diaphragmatic nodules:
a. asbestosis
b. sign of end-stage pulmonary fibrosis
c. sarcoidosis
d. bronchiectasis
a. asbestosis
What is the end-stage sign of pulmonary fibrosis on a chest xray?
Honeycomb-size cavities
Patient has developed lung scars that have become fibrotic, they have:
Interstitial Lung Disease
Patient has engorgement of upper lobe vessels and fluid collection in dependent portion of the lungs. This is a sign of:
a. stroke
b. CHF
c. left sided heart failure
d. pulmonary edema
b. CHF
CHF has an increased cardiothoracic (C/T) ratio of:
> 0.5
Which radiographic finding best correlates with the finding of CHF?
a. kerley b lines
b. honeycomb size infiltrates
c. blunted costophrenic angles
d. consolidation
a. kerley b lines
Miscellaneous signs:
pleural effusion, fluffy peripheral infiltrates, increased vascular markings
How is the cardiothoracic ratio measured?
a. midline (spine) to right heart border
b. trachea to right heart border
a. midline (spine) to right heart border
T/F: C/T ratio should be measured at the widest point, no more than half (50%) the width of the thorax.
True
T/F: ‘Bat wings’ or ‘butterfly’ patterns can sometimes be seen on patients with interstitial lung disease.
FALSE
Can be seen on patient’s with PULMONARY EDEMA
How many ml should be present on a chest radiograph before the fluid from pleural effusion can be seen?
100 mL
Pleural effusion can be caused by either excessive fluid formation or excessive absorption in the lymphatic system.
True
What position should be used for a CXR to confirm pleural effusion?
Lateral decubitus (the fluid moves with gravity)
Radiolucency below the costophrenic angle seen in the presence of a pneumothorax is a:
Deep sulcus sign
What is the most common cause of lung consolidation?
a. atelectasis
b. pleural effusion
c. bacterial pneumonia
c. bacterial pneumonia
T/F: Lung consolidation does not collapse.
True
Ground glass appearance is found in which lung disorder:
a. ILD
b. ARDS
c. Atelectasis
d. Bacterial Pneumonia
b. ARDS
Acute injury to alveolar epithelial lining cells is a key feature of ARDS.
True
Which of the following are postprocedural cxr evaluations:
I. Central venous pressure
II. Pulmonary artery catheter
III. Chest tubes
IV. Nasogastric feeding tubes
I. Central venous pressure
II. Pulmonary artery catheter
III. Chest tubes
IV. Nasogastric feeding tubes
all of the above
If dense substances appear light or white, they are:
a. radiopaque
b. radiolucent
a. radiopaque
If low density substances appear dark or black, they are:
a. radiopaque
b. radiolucent
b. radiolucent
______ images appear more white.
a. overexposed
b. underexposed
b. underexposed
_______ images appear more black.
a. overexposed
b. underexposed
a. overexposed
T/F: Treatment should never be delayed while images are produced and interpreted.
True
Most routine type of imaging:
a. Anteroposterior (AP) view
b. Posteroanterior (PA) view
b. Posteroanterior (PA) view
Which radiographic view is commonly taken for portable imaging on bed bound patients (ICU)?
a. Anteroposterior (AP) view
b. Posteroanterior (PA) view
a. Anteroposterior (AP) view
t/f: in both left lateral and PA projections, the heart is closer to the film.
True
This minimizes cardiac magnification, AP xrays have more magnification artifact due to closer proximity
Lateral decubitus view is primarily used to:
I. see if pleural fluid is present
II. identify pneumothorax
III. determine presence of pneumonia
IV. identify CHF
I. see if pleural fluid is present
II. identify pneumothorax
I, II ONLY
Patients with suspected pneumothroax should be placed on _______ side, while patients with pleural effusion should be placed on _______ side.
a. unaffected, affected
b. affected, unaffected
c. affected, affected
d. unaffected, unaffected
a. unaffected, affected
Normal lung tissue has low density.
True
Cavities, blebs (darker)
