4
Q
What is the typical diet for a client with an acute gastrointestinal disorder with inflammation?
A
NPO (nothing by mouth) and IV fluids are started to prevent dehydration.
This is to decrease inflammation and preparation for possible surgery.
5
Q
What is the typical diet for a client going for a gastrointestinal procedure or test?
A
NPO (nothing by mouth) for at least 4-8 hours. Some clients are taught to have a clear liquid diet only the day before some diagnostic tests.
This is to clean out the bowels and decrease the risk of aspiration.
6
Q
Describe:
Peritonitis
(Immediate complication)
A
It is when the bowel perforates causing infection and eventually sepsis if not treated.
7

10
Q
What are the interventions for an endoscopy?
A
- NPO for at least 4-6 hours
- will be sedated
- check for gag reflux afterward
- assess for signs of perforation afterward
11

14
Q
What is a capsule endoscopy procedure?
A
It is when the client swallows a capsule that has a small camera in it to look for abnormalities in the intestines. The client wears a belt that records the images.
Make sure the client is NPO 3 hours before and 3 hours after swallowing the capsule.
15
Q
What is an endoscopic retrograde cholangiopancreatography (ERCP)?
A
An ERCP is a scope that is inserted into the esophagus to look at the liver, gall bladder, and bile ducts - the hepatobiliary system.
Client will be getting dye, so assess for allergies.
16

A
- ensure that informed consent is signed
- get a set of vital signs and weight to assess for fluid shifts
- have client empty bladder to avoid puncture
18
Q
What are the interventions after a paracentesis?
A
- assess for shock and fluid and electrolyte imbalances
- record output
- get a sample and send to lab for analysis
- monitor for pink or bloody urine due to possible bladder puncture
19
Q
What is a liver biopsy?
A
It is when a needle is inserted through the skin into the liver to get a liver tissue sample for laboratory analysis.
20
Q
What are the interventions before a liver biopsy?
A
- Assess PT, PTT, and platelets - if high, there is risk for bleeding and procedure may be held
- give a sedative
- place in a supine or left lateral to access the right side
21
Q
What are the interventions after a liver biopsy?
A
Goal is to prevent bleeding:
- assess for bleeding and peritonitis

- no coughing or straining
- teach that there is no heavy lifting for at least 2 weeks
22
Q
What is the most common reason a stool specimen is collected?
A
To check for occult blood (blood that is not obvious to the naked eye).
23
Q
Describe:
Gastroesophageal reflex disease (GERD or “reflux”)
A
GERD is excess stomach acid that goes up the esophagus.
It is caused by excessive relaxation of the lower esophageal sphincter (LES).
24
Q
Who is most at risk of getting GERD?
A
Clients with a hiatal hernia or clients who are overweight.
Both conditions increase intra-abdominal pressure pushing the acid back up.
25
# Describe:
Hiatal hernia
It is when a **portion of the stomach herniates up through the diaphragm**.
## Footnote
It has the same symptoms of GERD and symptoms occur when laying down.
26
What are the severe **complications** of untreated GERD?
1. **Barrett's esophagus** - The damaged lining of the esophagus gets replaced with precancerous cells.
2. **Esophageal stricture** - The damaged lining of the esophagus gets replaced with scar tissue leading to difficulty swallowing.
27
What **substances** should a client with GERD avoid?
* caffeinated drinks
* chocolate
* citrus fruits, tomatoes
* smoking
* peppermint
* alcohol
* fatty foods
* large meals
## Footnote
These substances increase gastric acid production.
28
What is the **characteristic symptom** of GERD?
**dyspepsia** (heartburn)
## Footnote
The epigastric pain is due to acid entering the esophagus. These symptoms typically get worse when the client bends over.
29
What other **disease** can the symptoms of severe GERD imitate?
Myocardial infarction.
## Footnote
Many clients will visit the ER thinking they are having a "heart attack" when it is actually GERD. It is important to rule out a severe cardiac issue first.
30
What are the **diagnostic tests** for suspected GERD?
* **barium swallow** to check for esophageal problems like hiatal hernia
* **upper endoscopy** to look at the esophagus for abnormalities
* **pH monitoring exam** for 24 hours (a scope is placed in the esophagus and the pH is monitored)
31
# Teaching:
Lifestyle changes with GERD
* Limit or avoid foods that cause esophageal irritation
* Avoid smoking and drinking alcohol
* Avoid large meals, especially before sleep
* Sleep with the head of the bed elevated
* Avoid constrictive clothing, bending over and heavy lifting
32
# Medications:
GERD
1. **Antacids** - neutralizes stomach acid
2. **H2 receptor blockers**
* end in _-dine_
3. **Proton pump inhibitors** (PPIs) - prevents stomach acid from forming
* end in _-prazole_
33
What is the **last resort treatment** for a client with GERD?
Fundoplication surgery.
## Footnote
The gastric fundus is wrapped around the sphincter area of the esophagus.
34

What is a **colostomy** and **ileostomy**?
**A colostomy** connects the colon to the abdominal wall.
**An ileostomy** connects the small intestine (ileum) to the abdominal wall.
## Footnote
These operations are done because the bowel may have to be rerouted through an artificially created hole (stoma) in the abdomen so that stool can still leave the body.
110
What is the **difference in stool** between a colostomy and an ileostomy?
A _colostomy_ is made from the colon and puts out **more solid stool**.
An _ileostomy_ is made from the small intestine and **puts out more liquidy stool**, putting the client at a higher risk of fluid and electrolyte imbalances.
