obstruction? – ANSWER- – Bowel obstruction results in an abnormal
accumulation of air and fluid
- The overall density of the tissue is decreased due to the large amount
of trapped air in the bowel therefore resulting in a decrease in mAs
What should the tech do to provide radiation safety for all personnel
during an OR case? – ANSWER- Provide lead aprons and place the
image intensifier above the patient
A tech is performing a hip exam on an inpatient who is unable to stand.
The patient states that they need to urinate. How should the tech
