2024 RESPIRATORY EXAM QUESTIONS AND ANSWERS
RATED A ASSURED PASS
Pleural fluid layers and pneumothorax: What findings can be missed on a supine/portable X-ray?
decubitus view: What view helps to assess for free pleural fluid vs. localized fluid?
decubitus view: What view can help to demonstrate pneumothorax if the patient can't be imaged upright?
more: The further a structure is from the film, the (more/less) magnified it will be.
Heart magnified and lungs not as expanded: Problems with AP view?
pneumothorax and endobronchial obstruction: Expiratory views help to de- tect what pathology?
Lordotic: What view helps to assess lung apices?
Single slice: Type of CT that obtains one slice at a time and the table is discon- tinuously moved.
Spiral CT: Type of CT where patient is continuously moved through circulating beam with a cylinder of data obtained.
faster scanning and decreased motion artifact: Advantages to spiral CT
Multi-detector CT: Type of CT with 4, 8, 16, or 64 detectors that allows for even faster scanning of the patient
Mediastinum: Mediastinal windows on CT show structures in what compart- ment better?
Lung fields: Lung windows on CT show structures in what compartment better?
Multi-detector CT: Mediastinal and lung windows can be visualized on what type of CT?
High resolution CT (HRCT): What type of CT is used to give detailed look at lung parenchyma?
16..625mm: Slice size of HRCT slices
17.diffuse lung problem: HRCT is used in what type of lung problem? 18.HRCT: What type of CT doesn't use contiguous
slices that are separated by 10mm intervals?
HRCT: What type of CT has these indications for use
-pt with s/sx of lung disease but normal chest x-rays and/or thicker standard CT slices
-characterization of diffuse infiltrative pulmonary disease seen on chest x- ray or thicker standard CT slices
pulmonary emboli, aortic dissection, and aneurysm: Pulmonary CTA is used to detect...
Pulmonary CTA: Type of radiology where IV contrast is injected into vein and rapidly imaged as it goes through the
pulmonary arteries
15-20 years: How many years does it take to induce cancer after radiation exposure?
Dual energy CT: Type of CT that alternates between 140 and 80 kev x-rays?
,Dual energy CT: Type of CT that can distinguish contrast from calcium on imaging?
anatomic: X-ray and CT are (anatomic/physiologic) imaging studies? 26.physiologic: PET scan is a/an
(physiologic/anatomic) imaging study? 27.PET scan: F-18 FDG is most commonly used as a radiologic marker in what typ
of imaging?
malignant and inflammatory: F-18 FDG typically evaluates for what type of tissue?
PET/CT: What type of device fuses physiologic and anatomic information into one image?
PE: Nuclear medicine V:Q scan is used to assess for what condition... 31.when antecubital IV site can't be obtained or
patient has allergy to iodinat- ed contrast: Using V:Q scan over CTA
invasive and iodine contrast can damage kidneys: Downsides to pulmonary CTA
Pulmonary arteriogram: What is the gold standard for diagnosing PE
Spinous process centered between medial ends of the clavicle: Anatomical landmarks to determine proper frontal (AP)
positioning?
Improper frontal positioning: Density of one lung increases while the other decreases or unusual appearances to the hila
will be noted if this happens?
ribs superimposed and sternum will appear to have minimal thickness: - Anatomical landmarks visible in a well position
lateral film 37.Under: If you can see the lung markings but can't see the spine through the mediastinal structures, this i
a clue for (over/under)penetration of the x-ray?
Over: If all the details of the lung are totally lost, this is a clue for (over/under)pen- etration of the x-ray?
markings are noted throughout the lungs and vertebrae are visible through the heart: Clues for good x-ray penetration o
frontal view
good visualization of both lung markings and adequate penetration of the spine: Clues for good x-ray penetration on
lateral view
heart may appear enlarged and lungs may appear dense giving false appearance of pathology: Consequences of
inspiration not being sufficient on film quality
42.10 posterior ribs: How many ribs should be visible to ensure adequate inspiration?
RUL: What lobe of the lung is superior to the horizontal fissure and anterior to the oblique fissure?
Right: What pulmonary artery goes across the mediastinum?
L/L: The (L/R) pulmonary artery goes up and over the (L/R) upper lobe bronchus
46.6th anterior rib: What is considered adequate ventilation for infants on radiology?
above the 4th rib: What is considered hypoventilation for infants on radiology?
below the 8th rib: What is considered hyperventilation for infants on radiology?
Left: In the right decubitus view, better aeration of the lung is seen?
Right: In the left decubitus view, better aeration of the lung is seen?
, Insufficient inspiration: Decubitus view can be helpful in infants if there is
.
thymus: What structure in infants may mimic anterior mediastinal mass or cardiomegaly?
thymus: What structure in infants may appear as a "sailing ship" on radiology?
Right: Thymus normally projects to what side in infants?
RUL: Thymus normally simulates an infiltrate in what lobe of the lung in infants?
decubitus view: What radiologic view helps to differentiate between thymus and lobar infiltrate in infants?
thymus: What structure may involute with stress and then rebound and appear as a widened mediastinum in infants?
hyoid bone: The tip of the epiglottis projects just superior to the level of what anatomical land mark that is useful on
radiology?
CT of upper chest (to level of aortic arch): What radiological studies should be included for vocal cord paralysis?
R/R: The R/L recurrent laryngeal nerve goes under the R/L subclavian artery
L: The R/L recurrent laryngeal nerve goes under the aortic arch 62.Ludwig's angina: Condition that causes airway
obstruction above trachea and is due to cellulitis of the floor of the mouth?
<7mm,<21mm: Normal width of anterior cervical tissue at
C2
C5-C6
pinky: Epiglottis should be the size of your finger on normal radiograph.
AP projection: What view is more useful when assessing for croup?
steeple chase sign: What is the name of the sign when subglottic tissues are flattened and come to a point?
croup: Steeple chase sign is seen in what disease?
thickened soft tissues anterior to the spine: Retropharyngeal abscess has what appearance on radiograph?
Soft tissue density with trachea bowed: Enlarged thyroid has what appear- ance on radiograph?
esophagus: Orientation of an object in a right to left manner gives hint it is in what anatomical structure?
Left: What hilum is more superior?
azygos vein: The passes over RUL bronchus to join the superior vena cava
superior: The left pulmonary artery is in a slice that is (superior/inferior) to the slice that contains the right pulmonary
artery?
enlarged vessels, tumor, lymphadenopathy: Differential diagnosis with ab- normal appearing hilum on x-ray?
infectious, lymphoma, sarcoidosis, metastasis: Main differential for hilar adenopathy
