A

Controls the flow of fluid from one area to the other

30
Q

Classifications of stopcocks

A

male & female

31
Q

2 types of stopcocks

A

2-way and 3-way

32
Q

Difference between a 2-way & 3-way stopcock

A

2-way - allows the flow of fluid to and from two items

3-way - allows the flow of fluid to and from three items

33
Q

These are a series of stopcock attached to one another

A

Manifolds

34
Q

What are the purposes of waste management lines & bags?

A
  1. Facilitates the safe collection of fluid waste
  2. Also allows the administration of saline and contrast solutions
  3. Minimizes contact with infectious blood and bodily fluids
  4. Leak-resistant dual check valves make disposal clean and easy
35
Q

These are patented designs with built up
lip and recessed bottom

A

Sterile basins

36
Q

Purpose of the sterile basins

A

hold guidewire in place and allow easy removal

37
Q

What is the primary purpose of draping the surgical patient?

A

Isolate the surgical site from the other areas of the patient’s body and nonsterile areas of the O.R. table in order to contribute to reducing
the risk of surgical site infection (SSI)

38
Q

What is heparin?

A

It is a drug that works as an anticoagulant

39
Q

It is often used as a flush, which is a small amount of fluid run through an IV port or locks to dissolve any blood clots the patient might
have formed that could block the IV fluid from entering the vein

A

Heparin

40
Q

This provides a place to safely park needles prior to terminal disposal

A

Sharps container

41
Q

This closed bowl minimizes staff and patient exposure to blood-borne pathogens

A

Contaminated waste container

42
Q

What kind of contrast media is used in interventional radiography?

A

Non-ionic Low Osmolality Contrast Media

43
Q

What are the advantages of contrast-saver sets?

A
  • Minimizes contrast waste
  • Maximizes potential savings
44
Q

This facilitates the introduction of the catheter over the guidewire by dilating the path of the catheter

A

Vessel dilators

45
Q

What kind of measurement is used for vessel dilators?

A

French sizes

46
Q

what is the usual length of vessel dilators

A
