Q

Principles of Aseptic Techniques

A

Radiographers should not walk between two sterile fields if at all possible.
Radiographers should avoid turning their backs toward the sterile field in compromised spaces.
Watch the front of clothing when it is necessary to be next to the patient.

16
Q

When positioning an IR under the OR table, the radiographer should

A

Not lift the sterile drape above table level because this would compromise the sterile field

17
Q

***Method when Surgical technologist (CST) taking IR

A

Sterile IR cover is held open by the CST
–Radiographer holds IR while placing into sterile cover
–CST will grasp IR and wrap cover securely

18
Q

Method when Radiographer accepts IR after exposure:

A

Wear gloves to accept covered IR
•Blood/bodily fluids
–Grasp IR and open protective cover away from you and others so as not to spread any fluids
–Remove IR and dispose of IR cover in proper receptacle; remove gloves

19
Q

***Mobile fluoroscopic units also called

A

C-arm

20
Q

Function of Left monitor

A

Active or live

21
Q

***Function of Right monitor

A

Hold or last/saved image

22
Q

***Function of Cine loop

A

Images are recorded in rapid sequence and then displayed as a moving image (contrast injection)

23
Q

Operational Modes includes

A
Mag or magnification mode
Pulse mode
Snapshot or digital spot mode
Film mode
Auto/Manual Exposure
Subtraction
Roadmapping
Boost
Foot Pedal
24
Q

Pulse mode is

A

Pulsating beam at timed increments, reduces exposure

25
Q

Film mode uses

A

Standard IR

26
Q

Subtraction

A

Removes anatomy for better visualization

27
Q

***Roadmapping

A

Creates live subtracted image (Contrast studies)

28
Q

***Mini C-Arm used for

A

Extremity work (ER)
•Small and compact
•Limited dose & scatter radiation
–Lower energy levels

29
Q

***Radiographer should stand @ a

A
Right angle (90 degrees) to the primary beam and the object being radiographed.
•The least amount of scatter radiation occurs @ this position.
30
Q

***The greatest amount of scatter radiation occurs on the

A

A

Above the patient unless absolutely necessary

33
Q

A

4

35
Q
