Q

Vomiting can lead to:

A
  1. dehydration
  2. loss of Water and essential electrolytes
    - Metabolic alkalosis – loss of HCl from stomach
    - Metabolic acidosis – when contents of small intestine are lost (less common)

Q

What should the nurse assess emesis for?

A

Amount/frequency/character/color of emesis

Emesis contains partially digested food several hours after meal = gastric outlet obstruction or delayed gastric emptying

Color helps determine presence and source of bleeding (if present)

Blood in emesis could be from a

  • Mallory-Weiss tear
  • esophageal varices
  • gastric/duodenal ulcers or cancer

Q

What is care for someone with Cyclic vomiting syndrome?

A
  1. When in hospital, NPO and IV fluids until diagnosis is confirmed

  4. Monitor I/O, VS
  5. Quiet/odor-free environment
  6. Monitor mental status and risk for aspiration
    - If decreased mental status and risk for vomiting is present, then place side-lying
    - Older/unconscious/altered gag reflex all at increased risk (semi-Fowler’s or side lying)
  7. When PO started:
    - Clear liquids when PO is started
    a. Liquids at room temp
    b. progress slowly
    - Advance slowly from clear liquids to dry toast, crackers
    - Next advance to high carbohydrate / low fat
    - Eat slowly & small amounts
    - Fluids between meals (not with meals)

3. VTE prophylaxis and pain management
4. Nutrition- Jejunostomy or Gastrostomy tube
note: Monitor for anastomotic leakage into mediastinum
s/s: Pain, fever, dyspnea upon resumption of feeding
5. FOWLER’S OR SEMI-FOWLER’S POSITION
- prevents reflux
- Once drinking or eating, maintain upright 2-3 hours

38
Q

What is gastritis?

A

Inflammation of gastric mucosa

One of most common stomach problems

  • May be acute or chronic
  • Diffuse or localized

Causes:

  1. Breakdown of gastric mucosal barrier
  2. HCL & Pepsin into – mucosa
  3. Causing tissue edema and disruption of capillary walls
39
Q

What are risk factors for gastritis?

A

Drugs (ASA, steroids, iron supplements, NSAIDs)
-Even though NSAIDS are anti-inflammatory, they irritate the stomach

Diet

  1. Alcohol
  2. spicy food

Microorgamisms
esp Helicobacter pylori (H. pylori)

Environmental

  1. Radiation
  2. smoking

Pathophysiologic conditions
1. Burns, large hiatal hernia, physiologic stress, sepsis, more…

Other- endoscopic procedures, NG tube, psychologic stress

40
Q

What are S/S of gastritis?

A

Acute and Chronic Gastritis:

  1. Anorexia
  2. Nausea
  3. Vomiting
  4. Epigastric tenderness
  5. Feeling of fullness
  6. Hemorrhage
  7. Associated with alcohol

Chronic Gastritis:
Atrophy/loss of parietal cells causes the loss of intrinsic factor (IF) as well which is essential for the absorption of cobalamin (B12).
The loss of cobalamin absorption will cause:
1. anemia - IF needed for growth and maturation of RBCs
2. neurologic complications
- paresthesias of the feet and hands
- reduced vibratory and position senses
- ataxia
- muscle weakness
- impaired thought processes ranging from confusion to dementia

41
Q

What are common diagnostic studies for gastritis?

A

Patient symptoms and history of alcohol or drug use

Endoscopic examination with biopsy
- H. pylori infection: breath, urine, serum, stool, and gastric tissue biopsy

CBC (anemia due to lack of intrinsic factor)

Stool (occult blood)

Serum tests for antibodies to parietal cells & intrinsic factor

42
Q

What is care for chronic gastritis?

A

Eliminate & avoid cause

Drug therapy

  1. PPI
  2. Antibiotic (likely 2 different ones OR PPI, Bismuth [coats and protects], antibiotic, antifungal)

Non-irritating diet (six small meals/day)

NO smoking

43
Q

What does smoking do?

A

it causes an almost immediate, marked decrease in lower esophageal sphincter pressure
