Gastroenteritis
Inflammation of the stomach and intestinal tract
Affects primarily the small bowel
![Page 5: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/5.jpg)
Etiology and Risk Factors
Transmitted by the fecal oral route Person to person Ingestion of fecally contaminated food and
water Food is usually the vehicle for transmission Common bacteria sources of contaminated
food include eggs (salmonella), undercooked meat (E. Coli)
![Page 6: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/6.jpg)
The incubation period for all viral and bacterial infections
Ranges from 6 hours to 3 – 4 days.
Gastroenteritis
![Page 7: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/7.jpg)
Pathophysiology
Intestinal flora is disrupted by harmful bacteria and viruses or antibiotic therapy
Pathogens cause tissue damage and inflammation
Release of endotoxins causes greater secretion of water and electrolytes
Inhibition of Na absorption takes place caused by secretion of chloride and bicarbonates
![Page 8: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/8.jpg)
In order to create a Na balance, large amounts of protein rich fluids are secreted in the bowel overwhelming the large bowel’s ability to reabsorb the fluid leading to diarrhea
Pathophysiology
![Page 9: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/9.jpg)
Manifestations
Manifests as diarrhea abdominal pain cramping
Associated symptoms are nausea, vomiting, fever, anorexia, distension, tenesmus (straining on defecation) and hyperactive bowel sounds
![Page 10: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/10.jpg)
Prognosis
Temporarily disabling and self limiting for 2-3 days Resolves in 1-5 days Can be fatal in debilitated, older or very young people Early detection and treatment with fluid and
electrolytes are critical in preventing death or disability
Clients with E. coli may end up with hemolytic uremic syndrome which causes death
![Page 11: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/11.jpg)
Parasitic Infection (Helminths)
The intestinal tract may be infected with any of several helminths or parasitic worms e.g. roundworms, pinworms trichinella spiralis that causes trichinosis and species of tape worm.
Contracted through the skin or ingestion of contaminated food or water
May cause UTI or pruritus ani Susceptible to medications
![Page 12: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/12.jpg)
Outcome management for viral bacterial and parasitic infections Rest the Bowel
NPO until vomiting stops
Decrease diarrhea Obtain stool specimen if unresolved for 2-
3days Anti-Infective agent Avoid meds. that will decrease intestinal
motility
![Page 13: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/13.jpg)
Outcome Management for Viral Bacterial and Parasitic Infections Restore fluids and electrolytes
Small amount of clear liquid as tolerated Electrolyte beverage may be given Advance diet in 24hrs. as tolerated In severe fluid depletion start IV 0.45% NACL A potassium supplement may be ordered if K+
is low.

Nursing Management of the Medical Client Assess the stool for color, odor, consistency,
frequency and amount Assess bowel sounds, muscle weakness and fatigue Examine anal area for irritation, clean the area and
apply moisture barrier Administer anti-infective agent Replace fluid and electrolytes Provide discharge teaching
![Page 15: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/15.jpg)
Appendicitis
An inflammation of the vermiform appendix Most common in adolescence Can occur at any age but rare in children
under 2 years Not common in older adults Rupture occurs mostly in older adults
![Page 16: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/16.jpg)
Etiology and Risk Factors
Caused by a fecalith that occludes the lumen Kinking of the appendix Swelling of the bowel wall Fibrous conditions of the bowel wall External occlusion of the bowel by adhesions
![Page 17: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/17.jpg)
Pathophysiology
Due to obstruction, the intraluminal pressure increases leading to decreased venous drainage, thrombosis, edema and bacterial invasion of the bowel wall
Following initial obstruction, the appendix becomes increasingly hyperemic, warm, and covered with exudates, progressing to gangrene and perforation
![Page 18: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/18.jpg)
Clinical Manifestation
Vomiting which begins after the pain starts Loss of appetite Low grade fever Coated tongue Bad breath Elevated WBC (10 -15,000/mm3) Pain at McBurney’s point confirms diagnosis
![Page 19: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/19.jpg)
APPENDICITIS
DESCRIPTION Inflammation of the
appendix When the appendix
becomes inflamed or infected, rupture may occur within a matter of hours, leading to peritonitis and sepsis
MCBURNEY’S POINT
![Page 20: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/20.jpg)
Surgical Management
Appendectomy Done within 24 – 48hrs. Of onset of
manifestation Can be done through a small incision or a
laparoscope Delay will result in rupture of the appendix
leading to peritonitis
![Page 21: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/21.jpg)
Complications and Outcomes
Bowel perforation Antibiotics and surgical drainage is the
treatment Peritonitis D/C within 24-48 hrs. Lifting is restricted for 2-4 weeks Resume all activities in 4-6 weeks
![Page 22: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/22.jpg)
Nursing Management of the Surgical Client Assessment Pain management Fluid and electrolyte replacement Manage the risk for infection

Peritonitis
Inflammation of the peritoneal membrane
Causes sharp well localized pain
![Page 24: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/24.jpg)
Etiology and Risk Factors
May be primary or secondary Sources include G.I., external environment
and blood stream Offending organism is E. Coli No none risk factors
![Page 25: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/25.jpg)
Causes of Peritonitis
Ruptured or gangrenous gall bladder Perforated peptic ulcer Perforated stomach or intestine secondary to
cancer or inflammatory bowel disorder, bowel obstruction, penetrating wounds and acute pancreatitis
Early diagnosis is key
![Page 26: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/26.jpg)
Pathophysiology
The inflammatory response diverts blood to the inflamed area of the bowel
Peristaltic activity of the bowel ceases Fluids and air are retained within the lumen
raising the pressure and increasing fluid secretion into the bowel
Circulating blood volume diminishes
![Page 27: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/27.jpg)
The inflammatory process increases oxygen requirements
Difficulty in breathing results relative to abdominal pain and increased abdominal pressure
Pathophysiology
![Page 28: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/28.jpg)
Clinical Manifestation
Varies according to the cause
Pain – localized or generalized increasing with pressure
Rigidity of the abdominal muscle
Nausea and vomiting
Low grade fever Absence of bowel
sounds Shallow respiration Increased WBC
(20,000mm3) X-ray shows edema and
dilation of the intestines
![Page 29: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/29.jpg)

Crohn’s disease
Chronic relapsing disease Develops discontinuously
(without sequence) in any part of the alimentary tract
Most common location is the terminal ileum
Involves the entire thickness of the bowel wall
Mortality rate is not high Recurrence and complications
can lead to disability More common in whites and
Ashkenazi Jews

Etiology and Risk Factors
The cause of Crohn’s disease is unclear There appears to be a genetic or heredity
predisposition Considered to be autoimmune disease There are no preventive measures for
Crohn’s disease Only risk is genetic
![Page 38: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/38.jpg)
Pathophysiology of Crohn’s disease
Characterized by inflammation of segments of the digestive tract
Inflammation usually extends through all layers of the intestinal mucosa; this can lead to such complications as obstruction, tears, bleeding (anemia), and malnutrition
Consist of quiet (remission) and active (relapse) periods. In quiet periods, the patient is asymptomatic, in active periods, the patient experience symptoms
The cause is unclear although there appears to be a genetic or hereditary predisposition
![Page 39: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/39.jpg)
Diagnosis
Thorough history and physical examination CBC Serum chemistry Stool for occult blood Barium studies Endoscopy with biopsy
![Page 40: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/40.jpg)
Symptom’s of Crohn’s Disease
Stool may be foul smelling and fatty due to malabsorption (Steatorrhea)
Intermittent or chronic abdominal pain Diarrhea, may contain blood or mucous Stool is soft and semi solid Unexplained weight loss Anorexia, anemia Fatigue
![Page 41: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/41.jpg)
Indications for Surgery
Fistula Abscess Obstruction Malignancy Bleeding

Ulcerative Colitis
A disease that spans the entire length of the colon
Involves only the sub mucosa and mucosa
Begins in the rectum and distal colon spreading upward to the sigmoid and descending colon
Causes inflammation, thickening, congestion, edema and minute lacerations that ooze blood
![Page 43: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/43.jpg)
Develops into an abscess Bleeding from minor trauma More common than Crohn’s disease Occurs in all ages Higher incidence among young adults,
women and Jews Familial tendency
Ulcerative Colitis
![Page 44: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/44.jpg)
Etiology and Risk Factors
Bacterial origin Allergic reaction Altered immune state Presence of antibodies in the colon Emotional disturbance can precipitate an
exacerbation or prolong an attack No preventable risk factors
![Page 45: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/45.jpg)
Pathophysiology of Ulcerative Colitis
Appearance depends on the stage, activity and severity
Characterized by a crypt abscess (Inflammatory)
Secretions from crypt abscess result in purulent discharge from the bowel mucosa.
Abscess becomes necrotic and ulcerates
Inflammation reaction due to secondary infection leads to scarring, fibrosis, narrowing, thickening and shortening of the colon
![Page 46: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/46.jpg)
Clinical Manifestation
Abdominal pain Diarrhea (20x/day) Fluid imbalance Weight loss Metabolic acidosis Rectal bleeding Tenesmus Bloody stool
Sense of urgency Cramping Colicky pain in the LLQ Nausea, vomiting,
anorexia Anemia Low potassium May recur with
emotional distress

Medical Management
Decrease diarrhea Replace fluid, electrolytes and blood as
needed Restrict physical activity during attack to
decrease intestinal motility Keep record of loose stool, consistency, color Bowel rest/parenteral hyper alimentation Restore immuno competence Correct nutritional deficiency Relieve bowel edema and inflammation
![Page 48: Management of Clients with Intestinal Disorders NRS 108 SPRING 2008 LOLA OYEDELE MSN,RN,CTN MAJUVY SULSE MSN, RN, CCRN](https://reader036.vdocuments.mx/reader036/viewer/2022062323/5697bfde1a28abf838cb234a/html5/thumbnails/48.jpg)
Pharmacological Agents
Antidiarrhea medications e.g. Imodium, Lomotil
Metamucil may improve consistency of stool and control incontinence
Aminosalicylates – inhibits prostaglandin synthesis e.g. Azulfidine, Mesalamine and Olsalazine
Anti infective agents – prevent or control infection
Corticosteroids – reduce body’s response to inflammation e.g. prednisone, hydrocortisone
Give folic acid supplement Immunosuppressive
agents Anticholinergics – relieve
abdominal cramp and control diarrhea

Etiology and Risk Factors
Caused by Increased intra abdominal pressure
Pregnancy Constipation with prolonged straining Obesity CHF Prolonged sitting or standing Cirrhosis with portal hypertension

Pathophysiology
Tenesmus increases intra abdominal and hemorrhoidal veins pressure leading to distension of the veins
When the rectal pouch is filled with formed stool, venous obstruction occurs
The repeated and prolonged increase in this pressure and obstruction causes the hemorrhoidal veins to become permanently dilated.
As a result, thrombosis and bleeding may occur
