EXAM 1 Flashcards
Vagotomy
vagus nerve is cut to DECREASE gastric acid secretion (HCl)
Pyloroplasty
pylorus is widened to facilitate empting of stomach
Antrectomy/Billroth I (gastroduodenostomy)
removal of pyloric portion of stomach with anastomosis of duodenum to body of stomach
Billroth II (gastrojejunostomy)
removal of pyloric portion of stomach with anastomosis of jejunum to body of stomach
–> Pylorus is removed since this portion of GI tract contain parietal cells that secret gastrin
First complication of peptic ulcer disease
Hemorrhage
s/sx: bloody stool or emesis that is bright red or dark
Perforation and penetration
o Ulcer erodes through gastric serosa causing leakage of gastric contents flow into peritoneum and cause peritonitis
o Signs/symptoms:
Sudden, severe upper abdominal pain that gradually gets worse
Pain may refer to R shoulder d/t irritation of phrenic nerve & diaphragm
Vomiting
LOC
Extremely tender and rigid abdomen (board-like)
o *** Surgical emergency!!
gastric outlet obstruction
complication of peptic ulcer disease
o Occurs when area near pyloric sphincter becomes scarred and stenosed from spasms
o Scar tissue develops from healing ulcers overtime
o Signs/symptoms:
N/V
Epigastric fullness
o Treatment:
Insert NG tube for decompression
Stenosis/scarring of tissue may require dilation in order to relieve obstruction
Crohn’s Disease (type of IBD)
Aka, regional enteritis
Can occur in multiple segments of the GI system and is not contiguous
Cobblestone appearance and is not contiguous
Subacute and chronic inflammation of GI tract wall that spreads deep into all layers of affected bowel tissue
• Typically occurs in ileum & ascending colon but can be anywhere from mouth to anus
Ulcerative Colitis (type of IBD)
inflammation/ulceration that only involves colon and is contiguous (occurring one after the other in sequence)
Recurrent, ulcerative and inflammatory disease of mucosal and submucosal layers of colon and rectum
Lesions are connected together to form an unbroken sequence
Characterized by periods of remission & exacerbation
clinical manifestations of constipation
o Straining o Pain and pressure o Abdominal distension o Sensation of incomplete evacuation o Small, lumpy, dry, hard stools that are low in volume
causes of constipation
o Consuming low fiber diet
o Ignoring urge to defecate
o Inadequate fluid intake
o Sedentary lifestyle/lack of exercise
o Living fast-paced lifestyle usually marked by irregular eating patterns
o Medications (esp. anti-depressants & opioids)
o Chronic laxative use causes bowel dependence
o Certain neuromuscular disorders (MS, Parkinson’s) and endocrine disorders
complications of chronic constipation
o Valsalva Maneuver--> decrease CO and BP o Fecal impactions o Hemorrhoids o Fissures o Rectal prolapse o Megacolon
Nursing Management for chronic constipation
o Assess onset and duration of constipation
o Explore current and past elimination patterns
o Establish the norm of BMs
o Current medications & laxative, enema use
• Goal = restoring or maintaining regular pattern of elimination based on patient’s input
clinical manifestations of diarrhea
o Urgency o Perianal discomfort o Abdominal cramping/distension o Intestinal rumbling o Anorexia o Thirst
causes of diarrhea
o Medications – stool softeners, antibiotics, chemotherapy o Tube feeding formulas o IBS o Inflammatory bowel disease o C. Diff
complications of diarrhea
o Cardiac dysrhythmias – d/t K+ loss
o Dehydration
o Altered skin integrity (esp. around perianal area)
nursing management for diarrhea
o Obtain health history
o Any recent travel to another geographic location?
o Education!!
Foods to avoid – caffeine, carbonated beverages, hot/cold foods
Restrict milk products, certain fatty foods
o IV hydration may be necessary
Must monitor electrolyte levels
o Perianal care excoriated skin
Wet wipes
Barrier cream
dyspepsia
indigestion- pain in the upper abdomen and fullness in stomach esp without eating
pyrosis
heartburn
sliding hiatal hernia
occurs when upper stomach (usually just lower esophageal sphincter) and gastroesophageal junction (where stomach and esophagus join) are displaced upward to slide into and out of thorax
o Most common types – comprise 90-95% of all hiatal hernias
o Hernia usually slides freely
o Upper part of stomach and esophageal junction become displaced to slide in and out of thorax
rolling hiatal hernia
MAIN CONCERN= STRANGULATION
(Paraesophageal): occurs when all or part of the stomach pushes through the diaphragm and sits beside the esophagus
o Esophageal junction remains in position
o But fundus of stomach rolls through hiatus and into thorax
Sliding hernia clinical manifestations
o Can be asymptomatic
o ** GERD-like symptoms hallmark clinical manifestations
D/t involvement of lower esophageal sphincter
Pyrosis
Regurgitation
Dysphagia
Rolling hernia clinical manifestations
- involve more tissue so more likely to see respiratory symptoms o Can be asymptomatic o GERD-like symptoms o Breathlessness after eating o Chest pain that mimics angina o Feeling of suffocation o Worse lying down
Interventions for Crohn’s Disease
o Diet, activity and stressors
o Ready access
o Pain
o Fluid volume
o Daily weight
o Low residue diet review handout **
Foods that help to avoid overextending stomach and are easy to digest
Limits high-fiber, undigested foods that make up stool
Goal is to have fewer and smaller bowel movements a day
THERE WILL BE EXAM QUESTION on foods allowed/to avoid ***
o Rest periods to conserve energy and reduce metabolic rate
o Anxiety and coping
o Skin
o Understanding and management of self-care
o Signs of complications and when to seek medication attention
Goals for Irritable Bowel Disease
o Bowel elimination o Pain o Fluid volume o Maintenance of optimal nutrition and weight Malnutrition = top priority ** o Avoid fatigue o Reduce anxiety o Coping mind-gut connection!! o Assess skin and avoid skin breakdown o Knowledge o Self-health management o Avoid complications
Complications and Treatments for Irritable Bowel Disease
• Risks:
o Greatest risk = between age of 15-30
o UC more common in ex-smokers
o CD more common in smokers
• Causes: unknown
• Diagnostic: colonoscopy***
• Complications = Nutritional imbalance that can lead to malnutrition
o Diarrhea and subsequent anorexia can lead to:
Weight loss
Dehydration
Electrolyte imbalances
o Can overtime develop into cardiac dysrhythmias, osteoporosis
• Treatment:
o Surgery for UC total colectomy
Curative b/c it only affects the colon
For CD not curative b/c lesions can occur anywhere from mouth to anus
Clinical Manifestations of irritable bowel syndrome
o Primarily constipation or diarrhea or both
o Abdominal pain
o Bloating
o Abdominal distention
Interventions for irritable bowel syndrome
o Education
o Dietary habits and avoidance of trigger foods
o Chew and don’t drink fluids with meals can cause distension
o Stress management and exploring coping skills
What are the causes of Irritable Bowel Syndrome
o Psychological stress o Hormones o Genetics o Depression/anxiety o Trigger/fatty foods o Alcohol, smoking
surgical interventions for peptic ulcer disease
• If obstruction or perforation or ulcer won’t heal over 12-16 weeks**
o 1) Vagotomy: vagus nerve is cut to decrease gastric acid secretion (HCl)
o 2) Pyloroplasty: pylorus is widened to facilitate empting of stomach
o 3) Antrectomy/Billroth I (gastroduodenostomy): removal of pyloric portion of stomach with anastomosis of duodenum to body of stomach
o 4) Billroth II (gastrojejunostomy): removal of pyloric portion of stomach with anastomosis of jejunum to body of stomach
Pylorus is removed since this portion of GI tract contain parietal cells that secret gastrin
How can we diagnose someone with chronic gastritis?
Upper endoscopy
an order to obtain fecal occult blood
monitor H and H–> CBC lab work
Nursing Interventions for chronic gastritis
revolved around:
1) relief of pain
2) maintenance and balance of fluid and nutrition
3) reduce anxiety and provide education
a) If they have H pylori: combo of antibiotics
b) reduce NSAIDs and Alcohol
c) Smoking cessation
d) stress management
e) Avoiding trigger foods
What are the four areas that peptic ulcers can occur?
1) Duodenum
2) stomach gastric
3) pylorus- opening between the stomach and duodenum
4) esophagus
What are the two main causes of peptic ulcer disease?
1) H. pylori
2) excessive excretion of HCl by parietal cells
Also dx with an upper endoscopy just like for chronic gastritis
Clinical manifestations of Peptic Ulcer Disease
• Dull, gnawing, burning pain in mid epigastric area
o Pain may manifest posteriorly into the thoracic or lumbar region (back)
• Other symptoms:
o Pyrosis (heartburn)
o Vomiting
o Constipation or diarrhea
o Bloody stool or emesis
S/sx of anemia if bleeding is considerable
What are the treatments for peptic Ulcer disease?
• 1) IV antibiotics – Amoxicillin, Metronidazole
• 2) Bismuth salts to suppress H. pylori
Pepto-bismol
• 3) PPI –> to reduce gastric acid
Small Bowel Obstruction
o Most common causes = adhesions, hernias, neoplasms
o Often develop quickly
o More sharp pains than large bowel obstructions
Large Bowel Obstruction
o Most common causes = carcinoma, diverticulosis, IBD, benign tumors
o Usually develop over months
Sigmoid colostomy
solid: water has been absorbed through ascending and transverse
Descending colostomy
semisolid; less irritating
Transverse colostomy
middle or right side of abdomen; mushy; effluent more irritating because rich in gastric enzymes
ascending colostomy
right side of abdomen; semi liquid- rich in digestive enzymes; irritating to skin
What is the number one complaint of esophageal cancer and the clinical manifestations?
o #1 complaint = dysphagia ***
o Sensation that something is in throat or food gets stuck going down
o Weight loss
o Weakness
Treatment for esophageal cancer
Radiation and chemotherapy
resection of the esophagus
