Discuss the process of defecation and variables that may influence the process |
|
Definition
Defecation begins with movement in the left colon, moving towards the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter, and an awareness of the need to defecate.
Variables that may influence the process: 1. GI tract function 2. sensory awareness 3. voluntary sphincter control 4. adequate rectal capacity 5. compliance |

Nursing History (subjective) •History of illness or surgery R/T the GI tract •Usual pattern & habits – e.g. time of day •Usual characteristics of stool •Routines followed to promote elimination e.g. hot fluids •Use of artificial aids – laxatives, cathartics •Presence & status of bowel diversions – colostomy, ileostomy •Patient’s perception of normal or abnormal bowel elimination •Recent change in elimination pattern •Diet history – bulk in diet, daily fluid intake •History of Exercise •Travel history •Medication history •Emotional State •Social history – where the patient lives may affect toileting habits; do they have to share a toilet? •Mobility & Dexterity – getting clothes off; ability to get to bathroom •Post Operative abdominal surgery assess •Abdominal pain or discomfort •Flatus within previous 8 hours •BM within previous 12 – 24 hours •N & V •Feeling bloated •Return of appetite, feeling hungry •Abdominal cramping
Fecal Characteristics (objective) •Color – adult brown (black = upper GI bleed, iron) •Odor – affected by food •Consistency – soft, formed •Frequency – adult daily or 2 – 3 times a week •Amount •Shape – resembles the diameter of the rectum •Constituents – undigested food, fat, bile, water, etc.
Pertinent Laboratory and Diagnostic Tests (objective) • Fecal/Stool Specimens – must accurately obtain & label • Do not contaminate with urine, or toilet paper •If test is for fecal fat need 3 – 5 day specimen collection •Check to see if need warm specimen or can refrigerate stool •Guaiac Test – hemoccult, fecal occult blood testing •Diagnostic Examinations •Direct Visualization – performed under conscious sedation •Endoscopy – post test – no food or drink (NPO) until gag reflex returns •Gastroscopy – post test – NPO until gag reflex returns •Proctoscopy •Sigmoidoscopy •Capsule Endoscopy- visualize small intestine •Indirect Visualization •UGI Series; Barium Enema |

Discuss the mechanism of action, efficacy, and safety of current pharmacological agents used in the prevention and treatment of constipation |
|
Definition
1. Laxatives & Cathartics • Are used to prevent straining during defecation, prevent, & treat constipation • May be given to prepare patients for diagnostic tests & surgery • Cathartics have a stronger effect on the intestine • Use with caution – Stepwise approach is best – first bulk-forming laxatives, followed by stool softeners, osmotics, stimulants, suppositories, & enemas last
Categories: -Bulk Forming Agents – considered safest of all laxatives. Absorbs H20 to ↑ bulk, which initiates reflex bowel activity e.g. psyllium (Metamucil). Can cause obstruction if not mixed with an adequate amount of H20 (240 mL) Onset of action 12 hrs to 3 days - Stool Softener or Emollients – prevents straining during defecation & prevents constipation by ↓ surface tension of feces allowing H20 & fat to enter. Therapeutic effect 1 – 3 days e.g. docusate sodium (Colace), docusate calcium (Surfak) - Stimulant Laxatives– stimulates motility (peristalsis) by irritating the intestinal mucosa e.g. senna, bisacodyl (Dulcolax) Oral route = onset of action 6 – 8 hrs; Suppository = onset of action 15 – 30 minutes -Saline Laxatives – ↑ H20 content of feces = distention which initiate reflex bowel activity e.g. magnesium citrate, lactulose, MOM, fleet enema. Onset of action 1 – 3 hrs - Lubricant Laxative– coats the feces with an oily film & prevents the colon from reabsorbing water from the feces e.g. mineral oil. Avoid prolonged use – prevents absorption fat-soluble vitamins. Onset of action 6 – 8 hrs -Hyperosmotic Agent – ↑ intraluminal osmotic pressure in the bowel. Since they are not absorbed they draw H20 into the intestine, resulting in an ↑ volume which stimulates peristalsis e.g. glycerine suppositories. Onset of action 15 – 60 minutes after insertion. - Combination of stool softener & stimulant e.g. docusate & senna
2. Enemas •Types of Enemas – tap water, soap suds, oil retention, fleets, Harris flush •Side Effect – excess F & E depletion •Enema Administration – review in book
3. Digital Removal of Stool – review in book • Can stimulate the Vagal Nerve = reflex slowing of the heart rate 4. Chronic Constipation • New medication approved for chronic constipation – Amitiza (lubiprostone) • Acts to increase fluid in small intestines – dose 24 mcg BID
5. Bowel Training • Daily routine |

|
Definition
•Do not use longer than 2 days •Do not use if fever present •Non – pharmacological treatment – clear liquids •Maintenance of Skin Integrity – stool irritates skin and can cause breakdown •Categories 1. Absorbents – act by absorbing substances such as bacteria that could be the cause of the diarrhea e.g. bismuth subsalicylate (Pepto-Bismol) 2. Synthetic Opiates – are the most effective, they ↓ GI motility & slow peristalsis – e.g. paregoric, tincture of opium. Over-the-counter loperamide (Imodium) is an opiate-related agent 3. Antidiarrheal combinations – most contain a synthetic narcotic ingredient e.g. Lomotil |

Describe the role of the RN management of a client experiencing dysfunction in bowel elimination |
|
Definition
The role of the RN is to assess the history of the pt and assess a physical examination. You must auscultate to assess bowel in each quadrant and palpate for tenderness or masses.
Then the RN will then identify the correct diagnosis:
-Constipation R/T insufficient physical activity AMB no BM x 5 days -Risk for Constipation R/T ( dehydration AWBMB no BM x 3 days -Diarrhea R/T laxative abuse AMB 15 loose stools a day -Risk for Diarrhea R/T anxiety AWBMB loose watery stools -Bowel Incontinence r/t immobility AMB fecal staining of bedding and clothing -Dysfunctional Gastrointestinal Motility r/t pharmaceutical agents AMB abdominal distention and absent bowel sounds -Risk for Dysfunctional Gastrointestinal Motility r/t sedentary lifestyle AWBMB absent or hypoactive bowel sounds, abdominal distention and cramping, and difficulty passing stool
P: Critically think what the best strategies would be to reach the expected outcome or goals.
NI’s always work to change the etiology of the problem in order to resolve the problem Want to incorporate the patient’s elimination habits or routines as much as possible Least invasive nursing interventions (NI’s) and most cost effective should be initiated first – nonpharmacological treatment recommended
I: Implementation The RN will determine the best ways to treat the problem: Promotion of Regular Bowel Habits Take time to defecate Establish a routine – more likely to occur 1 hour after meals Promotion of Normal Defecation Squatting Position Positioning on Bedpan Promotion of Adequate Fluid & Food Intake Grapefruit juice & the caffeine in coffee, tea, colas, & chocolate drinks act as diuretics & take fluids from the bowel so these liquids should not be counted as providing fluid intake for bowel activity. Studies have shown a mixture of prune juice, applesauce, & bran can provide adequate fiber for effective bowel management. 2 cups Kellogg’s All Bran; 2 cups applesauce; 1 cup 100% prune juice. Promotion of Regular Exercise Promotion of Comfort Promotion of Self-Concept Avoiding straining and the Valsalva Manuver Laxatives & Cathartics
E: Evaluate The RN must determine if the pt was able meet the expected outcome. |
