CXRAY AHN568 EXAM QUESTIONS
AND ANSWERS
with a portable xray machine - ANSWER How is the AP usually
obtained?
when they cannot travel - ANSWER When is the AP indicated for
patients?
usually supine unless specified as upright - ANSWER What position is
the pt normally in for the AP xray?
achievement of optimal image, it produces more magnification and a
less sharp image - ANSWER The AP view may limit what?
it may limit inspiration and lead to misinterpretation, unable to reveal free
pleural fluid, posterior surface of the heart is flattened causing lateral
borders to be falsely widened - ANSWER In the supine position of the
AP view, what are 3 negatives?
in the xray suite in the upright position - ANSWER Where is the PA view
normally performed and what position is the patient normallly?
may allow for more optimal image, less magnification and more sharp
image - ANSWER The PA view helps with the image how?
deeper inspiration shows more lung, dependant free pleural fluid level
more evident, less distortion (widening) of cardiac silhouette - ANSWER
The upright position of the PA view, what are 3 positives?
with the film against the left side - ANSWER What position is the pt most
often in with lateral films?
structures in the posterior mediastinal and retrocardiac spaces and the
thoracic vertebrae - ANSWER What are lateral views useful in
evaluating?
, free pleural fluid - ANSWER What can the lateral view reveal that the AP
supine view may not find?
black - ANSWER a high degree of penetration will create a ____ area on
the film?
white - ANSWER a low degree of penetration will create a ____ area on
the film
low - ANSWER a high degree of penetration means there is ____
absorption
high - ANSWER a low degree of penetration means there is ____
absorption
the intensity of the xray beam - ANSWER Detail of the image is largely
determined by?
the clarity of the vertebral bodies in the image - ANSWER What is
optimal penetration generally judged by?
overpenetration - ANSWER the beam is too intense resulting in overly
dark image with subtle details rendered invisible
underpenetration - ANSWER beam is insufficiently intense, producing an
overly white image all detail lost in the glare
perpendicular - ANSWER The xray beam should be ____ to the film
and/or anatomical plane in order to avoid distortion of structural
relationships and sizes
clavicular symmetry - ANSWER in the PA/AP views, what is a general
indicator of chest rotation from the perpendicular plane?
clavicles should be approx equal in length, clavicular heads should be in
the chest midline - ANSWER What are you looking for with clavicular
symmetry?
