Question Answer
On a standard Xray study of the chest, which of the following are the most common two views? I. Posterior-anterior II. Anterior-posterior III. Lateral IV. Apical lordotic a. I and III b. I and IV c. II and III d. II and IV a. I and II
When the posterior-anterior (PA) view is compared w/ the anterior-posterior (AP) view: a. heart shadow on the PA view is larger b. heart shadow on the AP view is larger c. apices are more easily visualized on the AP view d. PA view is often a portab b. the heart shadow on the AP view is larger
Which of the following has the greatest radiodensity? a. air b. fat c. water d. bone d. bone
A possible nodular anomaly is present in the right upper lobe on a PA film, but partially obscured by the clavicle. What view might show the anomaly better? a. AP projection b. Lateral projection c. Apical lordotic projection d. L. anterior oblique pr c. Apical lordotic projection
During full inspiration, the hemidiaphragms on an adult chest film should be: a. at the C5 vertebra b. at the level of the 12th rib c. at the L4 vertebra d. at the level of the 10th rib d. at the level of the 10th rib
When evaluating a PA film of the chest, you note that the right costophrenic angles are blunted. What does this suggest? a. pneumothorax b. presence of an infiltrate in the right lower lobe c. presence of atelectasis in the right base d. presence of d. presence of a pleural effusion on the right
When evaluating a PA film of the chest, you note that in the upper lobe there is a 1 cm wide sliver along the lateral margin, descending from the apex, merging w/the ribs at the 3rd rib. This narrow sliver is very black & devoid of vascular markings. This a. pneumothorax
For evaluating the position of an ET tube on an AP chest film, the tip of the ET tube should rest: a. at the carina b. at the 4th rib space c. at a point 2-3 cm above the carina d. just above the clavicles c. at a point 2-3 cm above the carina
When viewing a V/Q scan, you note ventilation to be even on all views. On the perfusion scan, you note absence of perfusion in the right apical posterior segment. This finding suggests: a. pulmonary infiltrate b. atelectasis in the right apical posterio c. a possible pulmonary embolus
A pulmonary angiogram is used to: a. image the ventilation of the lung b. image the perfusion of the lung c. image the lymph system of the lung d. none of the above b. image the perfusion of the lung

Term Definition
what would a normal chest x-ray show? trachea is midline, bilateral radiolucency, with sharp costophrenic angles
what can cause a loss of airway patency? foreign body obstruction, edema such as croup or epiglottitis or allergic reaction, tracheal spasms, internal or external compression or a trauma leading to air leak
where should the tip of the ETT be positioned on chest x ray below the vocal cords and no closer than 2cm or 1 inch above the carina. which is also the same level of the aortic knob or aortic arch. (if above the clavicle it is to high.)
where should the pacemaker be positioned? in right ventricle
where should the pulmonary artery catheter appear in the right lower lung field
where should the central venous catheter be placed? in the right or left subclavial or juhular vein and should rest in the vena cava or right atrium of the heart
where should a chest tube be located ? in the pleural space surrounding the lung
where should the nasogastric tubes and feeding tubes be located? in the stomach 2-5 cm below the diaphragm
croup or laryngotracheobronchitis will look like what on a x ray of the neck? a steeple sign , picket fence or a pencil point
epiglottitis will show what on a lateral neck x ray? supraglottic narrowing with enlarged and flattened epidlottis and swollen aryepiglottic folds. this is known as thumb sign
besides croup and epiglottitis what will cause airway narrowing edema,secreations, tumors, aspiration of a foreign body
what is raidiolucent on a chest x ray? Air it is a dark pattern which in normal in the lungs
what is radiodense/opacity on a chest x ray? its solid or fluid it is a white pattern which is normal for bones and organs
what diagnosis would you have if your chest x ray had infiltrates? atelectasis
what diagnosis would you have if your chest x ray had a consolidation? pneumonia or pleural effusion
what diagnosis would you have if your chest x ray showed hyperlucency COPD or asthma attack
what dose a increase in vascular markings mean? CHF
if vascular markings are absent this would mean pneumothorax
how would pulmonary edema show up on a chest x ray ? fluffy infiltrates might have a butterfly/ batwing pattern
how would atelectasis show up on chest x ray? pattchy or platelike infiltrates
how would ARDS or IRDS show up on chest x ray ? ground glass appearance, honeycomb pattern, diffuse bilateral radiopacity
how would pleural effusion show up on chest x ray? concave superior interface/border or basilar infiltrates with meniscus
