Question | Answer |
---|---|
Process of digestion begins here | Mouth |
Located at base of esophagus into the stomach, where it prevents reflux of stomach contents | Cardiac Sphincter |
A secretion of the stomach, helps to digest proteins | HCL (Hydrochloric Acid) |
Digestive enzyme that acts as a catalyst in chemical breakdown of protein | Pepsin |
A secretion of the stomach needed for the absorption of B12 | Intrinsic Factor |
A secretion of the stomach that protects the stomach from HLC and enzyme activity | Mucous |
Contraction of circular muscular fibers | Segmentation |
Part of the small intestine -2 ft. long, processes the chyme from the stomach | Duodenum |
The amount of liquid chyme that moves thru the digestive system every day | 7 to 10 liters of liquid chyme |
Part of the small intestine, 9 ft. long, absorbs carbohydrates and proteins | Jejunum |
Part of the small intestine, 12 ft. long, it absorbs fats, bile salts, some water, some vitamins and iron | Ileum |
Most nutrients and electrolytes are absorbed in these two small intestines | Duodenum And Jejunum |
5-6 ft. long, primary organ of bowel elimination | Large Intestine (colon) |
Section of large intestine, a pouch where ileum meets large intestine | Cecum |
Section of large intestine on the right side of the body | Ascending Colon |
Section of large intestine that is across the abdomen | Transverse Colon |
Section of large intestine that is on the left side of the abdominal cavity | Sigmoid |
Section of the large intestine, that is on the left side of the abdomen | Descending Colon |
Functions of the colon (large intestine) | Absorption, secretion and elimination |
Final portion of large intestine, normally is empty until just before defecation | Rectum |
Permanent dilation, engorgement of veins within lining of rectum | Hemorrhoids |
Where feces and flatus (gas) are expelled from rectum by contracting of internal and external sphincters | Anus |
In the GI tract, supplied with sensory nerves that help maintain continence | Anus |
Normal defecation requires: | Normal GI tract function, Sensory awareness of rectal distention, Voluntary sphincter control, Adequate rectal capacity & compliance. |
Straining of stool with forced expiration against closed airway - assist in stool passage. | Valsalva Maneuver |
Lack of enzyme lactose, needed to digest sugars in milk. May lead to diarrhea and cramping | Lactose intolerance |
Diagnostic test which requires the ingestion of barium | Barium Enema |
What should the nurse do after the patient has a Barium Enema? | Patient should be ordered a laxative, & should increase PO fluid. Nurse watches stool to be sure barium is eliminated. Watch for lightly colored stool. |
Liquefies intestinal contents for easier passage | Fluid Intake |
Soften stool and promote peristalsis | Laxatives |
Medications that decrease peristalsis | Narcotics, Opiates, and Anticholinergics |
Medications that may cause diarrhea because they alter the normal bacteria found in the bowels | Antibiotics |
Medication that inhibit peristalsis | Antidiarrheal Agents |
Medication that cause stool to turn black, tarry and or green | Iron Preparations |
Medication that may result in frank blood or occult blood in stool | Anticoagulants |
Blood that can be seen with the naked eye (see red) | Frank blood |
Blood is hidden (may smell foul) need to take test for blood in lab | Occult blood |
Medication that causes white discoloration | Antacids |
Halts peristalsis (temporarily) | Anesthesia |
Bowel surgery that may cause halt in peristalis | Paralytic Ileus |
A condition with fewer bowel movements (BM's) than normal, with difficult passage of hard, dry feces | Constipation |
Occurs as a result of unrelieved constipation. A collection of hardened stool, becomes wedged in rectum, cannot be expelled | Impaction |
Increased frequency of passage of loose stool. Fluid & electrolyte imbalances can occur. Also, dehydration & rectal soreness | Diarrhea |
Age groups that are at risk for diarrhea | Elderly and very young |
Both of these diseases cause inflammation & ulceration of intestinal walls, decreasing absorption of fluids with increased intestinal mobility. | Crohn's disease or Colitis |
Removal of all or part of the stomach | Gastrectomy |
Surgical alteration which decreases the size of the colon | Colon Resection |
Involuntary passage of stool | Bowel Incontinence |
Sensation of bloating, abdominal distention, accompanied by excess gas (forces the diaphragm up and decreases lung expansion) | Flatulence |
Masses of dilated blood vessels lying beneath the lining of the skin fold in the anal mucosa | Hemorrhoids |
A temporary or permanent artificial opening from the intestine, to the abdominal wall | Stoma |
An incontinent ostomy which produces a frequent, liquid stool, it bypasses the colon | Ileostomy |
An incontinent ostomy which almost produces a normal stool | Sigmoid colostomy |
Incontinent ostomie - usually temporary, large stomas, made in the transverse colon:surgeon pulls a loop of bowel on to the abdomen | Loop colostomy |
Incontinent ostomie: just the proximal end drains stool- the distal end is either removed, or sewn closed & left in abdomen | End Colostomy |
Incontinent ostomie: 2 distinct stoma's with separate portions of intestine brought out onto the abdomen | Double Barrel colostomy |
Continent ostomie: colon is removed: pouch is created & ileum is connected to an intact anal sphincter - there is no ostomy | Ileoanal Pull Through |
Continent ostomie: restorative proctocolectomy: an internal puch with no external stoma - internal pouch created from ileum | Ileoanal Reservoir |
Continent ostomie: uses small intestine to create a pouch, there is an ostomy on abdomen, but a one way valve opens with fecal matter | Kock Continent Ileostomy |
Blood test: a by product of Hemoglobin (HgB) excreted in bile- obstruction of the biliary tract - an increase in direct values | Total Bilirubin |
Blood test: an enzyme found in many tissues, obstruction of biliary tract | Alkaline Phosphatase |
Blood loss in stool > 50 mls | Melena |
Measures microscopic amounts of blood in stool- one positive result does not confirm - should be repeated 3X to be considered positive | Guiac Test |
Stool analysis to check for bacteria, also test for fecal fat, patient collects stool over 3-5 day period - all stool must be saved | Culture and Sensitivity |
Adult: normal daily amount of fecal matter eliminated | 150 g daily adult |
Diagnostic Exam: kidney, ureter, and bladder - is also a plain abdominal x-ray - used for detection of fecal impaction - no prep | KUB |
Diagnostic Exam: x-ray using opaque contrast dye which patient must drink barium. examines structure & upper GI tract | Upper GI (UGI) - Barium Swallow |
Diagnostic exam: a lighted, flexible scope which can allow for direct visualization or upper GI tract - can obtain biopsy also | Upper Endoscopy |
Diagnostic exam: opaque contrast used for exam of lower GI tract - prep NPO after midnight & bowel prep to empty out remaining stool | Barium Enema |
Diagnostic test: sound waves echo off body organs, creating a picture - prep: depends on organ to be examined | Ultrasound |
Diagnostic test: endoscopy of colon with colonoscope inserted via rectum - prep: Golytely (drink) | Colonoscopy |

Diagnostic test: may be NPO or no prep, patient lies very still, light sedation may be used | Cat Scan |
Diagnostic test: uses magnetic & radio waves to produce a picture of inside the body, prep NPO 4-6 hrs before test - no metal or jewelry | MRI (Magnetic Resonance Imaging) |
Medication: empty the bowel, are stronger than laxatives, more rapid | Cathartics |
Medication: can cause local irritation to intestinal mucosa, and decrease water re-absorption of the large intestine | Stimulant Cathartics |
Medication; cause water to be reabsorbed by the fecal mass (salt prep not absorbed by intestines) | Saline or Osmotic Agents |
Medication: examples of Saline or Osmotic Agents | MOM (Magnesium Hydroxide) & Sodium Phosphate |
Medication: also called stool softeners - are detergents which decrease the surface tension of feces | Wetting Agents |
Medication: a stool softener which the nurse has to watch if on sodium restriction | Docusate Sodium |
Medication: a stool softener which renal patients can not take | Dioctyl Calcium Sulfosuccinate |
Medication: SAFEST OF ALL CATHARTICS - nurse should encourage plenty of fluid intake if used | Bulk Laxatives |
Medication: example of bulk agent (laxative) | Metamucil |
Medication: soften fecal mass, decrease strain of defecation. Good for patients with hemmorrhoids | Lubricants |
Medication: will cause lipid soluble pneumonia if aspirated. Difficult to treat - be sure patient can swallow well | Mineral oil |
