Diet that can lead to constipation low intake of fiber and fluids
Lifestyle that can lead to constipation low exercise, low mobility, chronic laxative use
Age-related factors that lead to constipation weakness, weakened muscles needed for defecation, fatigue
Fecal impaction stool so dry and hard it cannot be passed
Ulcers From pressure on the colon mucosa
Incontinence small amounts of liquid stool ooze around the fecal mass
Constipation and straining Valsalva’s maneuver; can result in cardiac, neurologic, and respiratory complications
In patients with history of HTN, heart failure, or recent MI what can straining cause cardiac rupture and death
Megacolon Grossly dilated loops of bowel develop proximal to the dry fecal mass and obstruction can occur
Chronic Laxative Abuse Colonic mucosal atrophy, muscle thickening, and fibrosis; can lead to perforation and need for emergency colectomy
Constipation therapeutic Interventions high-fiber diet, 2 to 3 L fluid daily; setting a daily defecation schedule and responding promptly to the urge to defecate
Constipation Nursing Goal patient will pass soft, formed stool every 1-3 days
Nursing interventions for Constipation bowel history; specific time for defecation; footstool; high-fiber, high-residue diet; increase fluid intake to 2-3 liter/day, if not contraindicated; increase daily activity and abdominal exercises
High-fiber and high-residue diet includes fresh fruits, vegetables, and whole grains with 2 gm. of bran added
Criteria for regular bowel function regular time of soft and formed defecation every 1 to 3 days; regular exercise; avoidance of laxative; 2-3 L of water; high-fiber and high-residue foods added to diet

Appendicitis complications perforation; abscess of appendix; peritonitis
s/s of peritonitis extreme tenderness over the area; aggravation of pain with movement; rebound tenderness; abdominal rigidity
Diverticulum outpouching of bowel mucous membrane caused by increased pressure within the colon and weakness of the bowel wall
Diverticulitis complication when food or bacteria become trapped in a diverticula, inflammation and infection develop
Diverticulosis/Diverticulitis causes chronic constipation; decreased intake of dietary fiber
Diverticulosis/Diverticulitis prevention increase dietary fiber; prevent constipation
Crohn’s Disease: skip lesions inflamed areas alternate between areas of healthy tissue
Chrohn’s disease complication fluid and electrolyte imbalance
Chrohn’s Disease medication: Budesonide (enterocort EC) synthetic anti-inflammatory corticosteroid; acts locally rather than systemically; administer in the morning; take the pill whole; do not take with grapefruit juice
Ulcerative colitis inflammatory bowel disease similar to Crohn’s but only occurs in the colon and rectum
Ulcerative colitis and surgery pouching can be done; surgery does cure ulcerative colitis

Foods that cause distress or gas formation fresh fruits and vegetable; spices; milk; coffee; carbonated beverages; alcohol
Abdominal hernia complications strangulated incarcerated hernia

Bowel obstruction symptom progression symptoms progress as obstruction worsens or becomes complete
Bowel obstruction, what may occur fecal vomiting and pain and abdominal distention
What is done to decompress the bowel in bowel obstruction NG tube
Lower GI Bleeding nursing care baseline vital signs
Report what finding with lower GI bleeding changes from baseline that determine bleeding and shock; also decreased BP and rising HR
Higher risk people for colorectal cancer with personal or family history of ulcerative colitis, colon cancer, polyps of the rectum or large intestine
Major causative factor of colorectal cancer lack of dietary fiber; Prolonged fecal transit prolongs exposure to carcinogens; bacterial flora is altered by excess fat which converts steroids into compounds having carcinogenic properties
Other causative factors for colorectal cancer obesity, smoking, alcohol intake, large intake of red meats
Ileostomy end stoma formed by bringing the terminal ileum to abdominal wall after total colectomy
Conventional ileostomy small stoma RLQ; continuous flow liquid effluent
Continent ileostomy internal reservoir with nipple valve; empty reservoir 3 to 4 times daily to prevent pouch rupture
