Oral Assessment Abdominal Assessment Rectal Assessment Factors affecting bowel elimination Age Diet Fluids Physical activity Personal habits Pain Pregnancy Surgery & anesthesia Medications Effects of Aging Mouth o Teeth loosen, reduced circulation to gums, teeth darken and fracture o Decreased output of salivary glands o Decreased stimulation of taste buds Stomach o Atrophy of gastric mucosa o Decreased secretion of hydrochloric acid o Decreased bile secretion Decreased muscle tone and strength Diagnostic Tests Lab tests o Bowel preparations o Colonoscopy o Provides direct visualization of the rectum, colon, entire large intestine, and distal small bowel. A flexible scope is inserted through the rectum and advanced to the cecum. o Useful in detecting lower GI disease. o Positioning: LT side with knees to chest o Anesthesia: Moderate sedation (Midazolam, fentanyl, and/or propofol) o Prep ▪ Bowel Prep (laxatives, such as bisacodyl and polyethyline glycol) ▪ Clear liquid diet, NPO after midnight ▪ Patient must avoid medications such as aspirin, anticoagulants, and antiplatelets. o Post ▪ Monitor for rectal bleeding ▪ Do not drive or use equipment for 12-18 hrs after Laparoscopy o The peritoneal cavity, pelvis, and abdomen are examined. This test is used to detect cysts, adhesions, fibroids, infections of the uterus, fallopian tubes, and ovaries, ectopic pregnancies, liver lacerations, and cirrhosis. Esophagogastoduodenoscopy o Insertion of endoscope through the mouth into the esophagus, stomach, and duodenum to identify or treat areas of bleeding, dilate an esophageal stricture, and diagnose gastric lesions or celiac disease. o Position: LT side laying with head of bed elevated o Anesthesia: Moderate sedation per IV access. Topical anesthetic to depress gag reflex, atropine to decrease secretions. o Prep: NPO 6-8 hrs. o Post: Withhold fluids until return of gag reflex Proctosigmoidoscopy o Digital examination to dilate the anal sphincters to detect obstruction that might hinder passage of the endoscope, a sigmoidoscope to examine the distal sigmoid colon and rectum, and a proctoscope to examine the lower rectum and anal canal. The proctosigmoidoscopy is used to identify internal hemorrhoids, hypertrophic anal papillae, polyps, fissures, fistulae, and rectal and anal abscesses. Paracentesis o The aspiration of fluid from the abdominal cavity. Nutrition Support Daily weights Gastrostomy feedings o Patients require 25–30 kcal/kg/day and 30 mL free water/kg/day. o If the feeding tube will be used for less than 30 days, select a nasogastric tube in the range of 8-Fr to 18-Fr. A larger bore nasogastric tube allows for suction if needed. Smaller tubes, 8-Fr to 12-Fr, are used for intestinal feeding (duodenal and jejunal). Parenteral nutrition o Providing nutrients to patients in an intravenous (IV) solution. Functions of the Kidney (A WET BED) Acid-base balance Water removal Erythropoiesis Toxin removal Blood pressure control Electrolyte balance Vitamin D activation Acute Abdomen Pathophysiology o Three major pathological processes, inflammatory, obstructive, and vascular, can produce acute abdominal pain. Inflammation may be infectious or chemical, but regardless of cause, the chain of pathological events is the same. Affected structures demonstrate reactive hyperemic, with exudation of fluid into tissues due to increased vascular permeability and an increase of filtration pressure. Assessment o Pain score, SPECIFIC location, quality, duration, onset. o Vital signs o Review current medication list o Appetite o Bowel pattern and consistency o Bowel sounds o Distention Diagnostic tests o MRI - which is least invasive o CBC, BMP o Liver function test AST, ALT, albumin(low) and bilirubin will be evaluated to indicate any cirrhosis or hepatitis o Amylase increase will indicate pancreatitis o 12 lead electrocardiogram (ECG) Implementation o Ensure adequate hydration o Patient may need IV fluids duet to nausea or NPO status. o Control pain o Repositioning, heat/cold, analgesics, muscle relaxants o Monitor I&Os o Bowel monitoring Crohn’s Disease
