A

Physical property of liquids that determines the internal resistance to shear forces.

25
Q

What is the most common type of NG tube?

A

Levin Tube

26
Q

How can leakage form a double-lumen tube be prevented

A

The barrel of a piston-like syringe may be inserted into the suction-drainage lumen, and it is pinned to the patient’s gown with the barrel upwards

27
Q

What should you do with a bed pan after use?

A

Cover, then empty contents in toilet. Most bed pans today are single use and can be thrown out in the non- regulated trash. Metal pans are to be emptied and sent to SPD for resterilization.

A

Approximately 500ml of fluid

31
Q

Desirable characteristics of a barium suspension include

A
  1. Allow rapid flow
  2. Allow good adhesion to the mucosa for even coating
  3. Provide adequate radiographic density in a thin layer
  4. Lack foam or artifacts
32
Q

A postural drop in blood pressure can occur after a BE as a result of

A

Dehydration

33
Q

With a double barrel colostomy, the proximal stoma delivers _________ and the distal stoma produces ___________.

A

Proximal delivers stool
Distal produces mucus

34
Q

Approximately what percentage of colostomy patients have recurrences of cancer?

A

10%

35
Q

Describe a Levin Tube

A

A tube with a single lumen with several holes near its tip

Q

Types of NG tubes

A

Canor,Keofeed, Miller-Abbott, ad Sengstake-Blakemore

37
Q

Name the 5 basic types of cleansing enemas

A

tap water (hypotonic), hypertonic solution, physiologic, soapsuds, and oil retention

38
Q

Name some clinical indications for a flouroscopic contrast enema.

A

Diverticular disease, IBS, ulcerative colitis, Crohn’s Disease, Colon cancer screening, incomplete colonoscopy, distal intestinal obstruction syndrome or meconium ileus equivalent in cystic fibrosis patients, abnomal or inconclusive findings on other imaging such as CT, polyps.
