d. right internal jugular access and should only be used in cases of emergency. The right internal
jugular vein is more commonly used for central venous access and is not a
common site for venipuncture.

The AEC controls which of the following exposure c. seconds
variables?

b. focal spot size technical factors are chosen by the radiographer.
The ______ receives electrons immediately after they are d. analog-to-digital converter
read out from an imaging detector.

An image that has many shades of gray with few b. low contrast
differences among them is defined as exhibiting:
a. high spatial resolution Low-contrast images consist of many gray shades with very little differences
b. low contrast among the shades. These images are also referred to as exhibiting long-scale
c. high dynamic range contrast. Spatial resolution deals with image sharpness and dynamic range is
d. low bit depth the imaging detector's range of response to exposures. Bit depth has to do
with the number of gray shades that a system can yield. A low bit depth system
would actually result in an image that displays few shades of gray. In other
words, the image would appear more black and white.
Which of the following structures is located in the d. trachea and thymus
mediastinum?
a. right middle lobe and esophagus Structures located in the mediastinum are the heart, great vessels, trachea,
b. left upper lobe and heart esophagus, thymus, lymphatics, nerves, fibrous tissue, and fat.
c. aorta and thyroid
d. trachea and thymus
