Chapter 47 & Chapter 30: Bowel Elimination
Scientific Knowledge Base
Components involved in bowel elimination: Mouth, Esophagus, Stomach, Small intestine, Large intestine, Rectum, Anus and finally defecation
Nursing Knowledge Base
Factors that influence bowel elimination: age, diet, fluid intake, physical activity, psychological factors, person habits, position during defection, pain, pregnancy, surgery and anesthesia, medication and diagnostic tests.
Common Bowel Elimination Problems
Constipation, Diarrhea, Incontinence, Flatulence, Hemorrhoids
Bowel diversions: Ostomies,
Other procedures: Ileoanal pouch anastomosis
Critical Thinking in Bowel Elimination
Integrate knowledge from various disciplines to understand patient responses to bowel elimination issues.
Use critical thinking attitudes (e.g., fairness, confidence, discipline) and apply relevant standards when choosing nursing measures.
Nursing Process: Assessment
Through the patient’s perspective: Assess based on history, environmental factors, physical examination of the mouth, abdomen, rectum. As well as laboratory tests, fecal specimens, and diagnostic examinations.
Epigastric- Above the umbilicus and between the costal margins.
Umbilical-around the naval
Suprapubic- above the symphysis pubis
Order of assessment: Inspect, Auscultate, Percuss, Palpate.
Abdominal regions: Epigastric, Umbilical, Suprapubic.
Abdominal assessment steps and details, including abdominal girth measurement and documentation practices.
Inspection:
Observe for: Symmetry, shape and contour, umbilicus, skin, movements and pulsations.
Auscultation of Bowel Sounds
Types of bowel sounds: Normal (5-35 sounds/min), Absent (5 min/quadrant), Hypoactive, Hyperactive (these are normally loud, growing sounds borborygmi)
Immediate reporting of vascular abnormalities, like bruits.
Bruits are narrowing of major blood vessels and disruption of flow, they should be reported immediately.
Normal: no vascular sounds over aorta or femoral arteries.
Percussion and Palpation
Percussion tones: Tympany, Dullness
Abdominal tenderness, distension, or masses (Light and Deep palpation).
Light palpation sounds only about ½ inches, should be smooth with consistent softness, non-tender and non masses.
Abnormal Stool Findings
Characteristics: Color, Odor, Consistency, Shape, Constituents
Color: White or clay (biliary issue), black or tarry (melena) Red, pale with fat, translucent mucus or bloody mucus.
Odor: Noxious change (absorption issue)
Consistency: Liquid hard
Shape: Narrow, pencil shaped
Constituents: Blood, pus foreign, bodies, mucus, worms, excess fat.
Significance of variations in stool appearance, e.g., white/clay color indicating biliary issues.
Laboratory Tests
Fecal specimens, collection techniques, and the importance of aseptic practices.
Tests like Occult Blood (Guaiac) for hidden blood.
Nursing Process: Analysis and Nursing Diagnosis
Common diagnoses: Bowel Incontinence, Constipation, Fecal Impaction, Diarrhea.
Contributing factors: irregular bowel habits, low fiber/fluid intake, anxiety, immobility.
Alteration in Bowel Elimination: Constipation
Signs/symptoms and risk factors (e.g., laxative misuse, medications, lack of exercise).
Consideration of co-morbidities like cardiovascular disease and glaucoma.
Alteration in Bowel Elimination: Impaction
Risk factors (e.g., confusion, immobility).
Symptoms and interventions, including gentle digital rectal exam if necessary.
Alteration in Bowel Elimination: Diarrhea
Causes and symptoms, including fluid/electrolyte imbalance and skin integrity concerns.
Causes like antibiotic use, food intolerances, C. difficile infection.
Alteration in Bowel Elimination: Incontinence
Issues with fecal and gas control, effects on social interaction and self-image.
Implementation: Promotion of Normal Defecation
Health promotion tips: sitting position, privacy, medications.
Digital removal of stool and colorectal cancer screening.
Positioning on Bedpan
Techniques for patient comfort, including head elevation for patients able to shift.
Instructions for immobile patients who cannot raise hips.
Implementation: Acute Care
Enema administration types: tap water, saline, soapsuds, hypertonic solutions.
Special considerations for patients with fecal incontinence or diarrhea.
Implementation: Continuing and Restorative Care
Care of patients with ostomies: Irrigating and pouching ostomies.
Nutritional and psychological considerations, bowel training, skin integrity maintenance.
Evaluation and Patient Outcomes
Evaluation through the patient’s experience.
Safety Guidelines for Nursing Skills
Instruct patients on side-lying position for self-administered enemas.
Check pulse for patients with cardiac concerns due to vagus nerve stimulation risks.
