1st Nobel winner in Physics

Answer 14

Wilhelm Conrad Roentgen

Question 15

Radiographic method of demonstrating certain anatomic features that lack natural contrast with surrounding structures by the instillation of a substance to produce structural contrast
Mostly in vessel, need contrast to see it

Answer 15

Special procedure

Question 16

Performed to identify a particular pathologic process

Used to localize certain vessels or tumors prior to the performance of therapeutic procedures

Answer 16

Diagnostic procedures

Question 17

Diagnostic procedure of the arterial system
CT vs CTA = CTA uses more contrast
Do one with and one without contrast

Answer 17

Arteriogram

Question 18

Vessel system in brain

Answer 18

Circle of willis

Question 19

No blood flow

Answer 19

Occlusion

Question 20

Diagnostic procedure best for venous system but can also see arteries

Answer 20

Venography

Question 21

Performed to read the pathologic process (ex: heart treatment)

Answer 21

Interventional procedures

Question 22

May require a Stent to open the vessel

Will affect blood pressure

Answer 22

Cardiac catheterization

Question 23

Minimum size = 400 square ft
4 ft wide doorways
Patient holding and monitoring area
Adequate radiation protection
Scrub area
High performance generator = typically use 700-1500 mA-80-100 kVp
May have to allow cooling time for the machine

Answer 23

Interventional radiography room

Question 24

These units cause the greatest patient doses of all diagnostic radiographic procedures, although they provide very high image quality
Used most often in cardiology and neuroradiology
Uses a “movie camera” to record the image from the image intensifier
Special care must be taken to ensure that patients are exposed at minimum acceptable levels

Answer 24

Cinefluorography - C-Arm - used in surgery

Question 25

5 components of automatic injectors

Answer 25

``` Control panel Syringe Heating device High pressure mechanism Tubing ```

Question 26

Pushes a predetermined amount of contrast into the tubing to displace air

Answer 26

Prime button

Question 27

Enables operator to confirm that no air is in the fluid path at the injector head to reduce the risk of an air injection

Answer 27

Remote check for air

Question 28

Enables the operator to arm the injector from the injector head

Answer 28

Remote arming

Question 29

Component of automatic injector that helps with viscosity of contrast; at or near body temperature

Answer 29

Heating device

Question 30

Touch screen on automatic injector that shows you: how much contrast is in syringe (usually hold about 200 cc), flow rate, how much you’re going to inject, if you want the injector “armed”, “dead man” type switch on the side, red and yellow buttons to start and stop injection, common screen displays and graph of flow when contrast is going in patient

Answer 30

Control panel

Question 31

Injection speed, can be increased or decreased (1 slow-5 fast); will peak then “flat line"

Answer 31

Flow rate

Question 32

Pushes the contrast through Can prevent injections from exceeding their preset volume, flow rate and pressure When you inject a lot of contrast at a fast flow rate, this creates pressure in the vessel therefore if you use a fast flow rate, it’s recommended to use a large needle so the pressure is lessened There is an emergency stop if you see there is an extravasation getting ready to occur

Answer 32

High pressure mechanism

Question 33

Why will you never use a butterfly needle with an automatic injector?

Answer 33

Too small gauge needle Not secured within the vein well enough for the pressure of the automatic injector Good for a quick hand injection or drawing blood

3 types of chest tubes and lines

Answer 34

Endotracheal tubes Central venous lines Pulmonary arterial lines

Question 35

Inserted into a large vein to administer drugs, manage fluid volume, transfuse and analyze blood and monitor pressures within the heart Used for patients who have to get multiple injections daily or hard to find a vein when hospitalized Most common site is the subclavian vein, other common sites include the internal jugular and femoral veins

Answer 35
