CAMRT practice exam question
When preparing to add antiseptic iodine to a sterile field, why must some of the liquid be poured into
the sink before adding the remainder to the sterile container? - Answer-To wash the containers lip to
prevent contamination, and to maintain sterile field
Why is the maximum injection pressure of an automatic injection device preset during contrast media
administration? - Answer-To prevent vessel damage
The QC tech performs testing after images acquired in the past week demonstrate exposure
inconsistencies. Which kVp accuracy test reading at 80 kVp would require corrective action? - Answer-
70. Because this is greater than the acceptable limit of 10%
A football player with broad shoulders presents with an obvious separation of the AC joint. What upright
bilateral AC joints projection should be taken to best demonstrate the condition? - Answer-With weights
at 180 cm.
- longer SID reduces magnification
What area of the gown is considered part of the sterile field? - Answer-The front of the gown, waist to
shoulder
What test must be performed first to ensure the validity of a mA linearity test results? - Answer-Timer
accuracy
- mA linearity assures that mA stations are accurate. The time and kVp accuracy must be verified prior to
evaluate mA linearity
What demonstrates minimal foreshortening of the femoral neck on on an axiolateral hip images? -
Answer-The greater and lesser trochanters are on the same transverse level
, Mr. Rogers presents with fixation devices protruding from the inferior aspect of his heel. The foot is
flexed 70 degree. Calcaneus images have been ordered. How should the tech. direct the CR for the axial
projection? - Answer-60 degrees cephalad
- the tech must increase the angle by 20 degree (40 + 20) to compensate for lesser dorsiflexion of the
foot
- angle should be 40 degree to the long axis of the foot
What will best demonstrate any medial or lateral displacement of a fracture of the ramus of the
mandible? - Answer-Axial AP (Towne)
What would best demonstrate air/fluid levels in the abdomen on an ICU patient who must remain
supine? - Answer-Dorsal decubitus
What are the most appropriate infection control measures for a patient with MRSA? - Answer-Gloves
and gown; keeping any linen used in the patients room
- gowns and gloves are only required because MRSA is transmitted by direct contact
What should be done when inserting the rectal tip? - Answer-Ask the patient to take slow, deep breaths
and insert the tip during exhalation
- exhalation promotes muscle relaxation, ensuring that the tip is easier to insert
A patient with non-Hodgkin's lymphoma arrives for a follow up ct chest scan. What precautions should
the technologist use? - Answer-Protective
- Protective precautions are employed to reduce the spread of infection to immune compromised
patients such as organ transplant recipient or chemotherapy patients
Which projection will best demonstrate the left axillary rib free of superimposition? - Answer-Left
posterior (ap) oblique
