Understanding Elimination in Med-Surg Nursing

Sep 26, 2024

Core Concepts in Med-Surg Nursing: Elimination

Introduction

  • Video geared towards med-surg nursing students
  • Useful for:
    • Fundamentals course
    • First med-surg courses
    • Adult complex health courses (near graduation/NCLEX preparation)
  • Focus: Understanding what happens inside the body for better assessment and care of clients

Elimination Overview

  • Definition: Excretion of waste from the body
    • GI tract: Feces
    • Renal/urinary system: Urine

Bowel Elimination

  • Result of food and fluid intake
  • Process:
    • Absorption in small intestine into bloodstream
    • Waste continues to large intestine
    • Eliminated through rectum and colon

Urinary Elimination

  • Result of kidney processes
  • Process:
    • Urine flows through urinary tract
    • Exits through urinary sphincter, urethra, and meatus

Interrelated Concepts

  1. Fluid and electrolyte balance
  2. Tissue integrity
  3. Nutrition

Concepts of Continence and Incontinence

  • Continence: Voluntary control over elimination
  • Incontinence: Lack of voluntary control
    • Bowel and/or urinary incontinence
  • Retention: Inability to excrete stool or urine

Bowel Elimination Continuum

  • Normal function: Midpoint
  • Diarrhea: Watery, liquid stool
  • Constipation: Hard, dry, difficult stool

Risk Factors

  • Aging: Decreased peristalsis, weak pelvic muscles
  • Neurologic disorders: Stroke, dementia, multiple sclerosis
  • Excessive laxative use: Diarrhea
  • Infections: Gastroenteritis, Crohn's disease
  • IBS: Diarrhea or constipation

Urinary Retention Risk Factors

  • Benign prostatic hyperplasia (BPH)
  • Spinal cord injuries
  • Renal/kidney stones
  • Chronic kidney disease

Stool Retention Risk Factors

  • Decreased peristalsis
  • Inadequate fiber and fluid
  • Lack of exercise
  • Opioid medications
  • Spinal cord/brain injuries

Consequences of Incontinence and Retention

  • Incontinence

    • Impaired tissue integrity
    • Depression/anxiety
    • Fluid and electrolyte imbalances (e.g., fluid volume deficit, hypokalemia)
  • Retention

    • Buildup of toxins/waste
    • Urinary retention: UTI risk, rare bladder rupture
    • Stool retention: Bowel impaction, potential obstruction

Assessment

  • Health history and physical exam
  • Monitor frequency, amount, and consistency of urine and stool
  • Auscultate bowel sounds
    • Hyperactive: Diarrhea
    • Hypoactive: Constipation
  • Palpation for retention
  • Diagnostic testing: Urinalysis, culture, imaging, ultrasound, bladder scan, stool culture

Health Promotion

  • Adequate nutrition and hydration
    • High fiber diet: Fruits, vegetables, whole grains
    • 8-12 glasses of water daily
  • Toilet when urge occurs
  • Bulk-forming laxatives or stool softeners

Interventions

  • Diarrhea: Seek medical attention for chronic cases
  • Constipation: Client education on diet, fluids, exercise
  • Urinary incontinence: Frequent toileting/bladder training
  • Urinary retention: Catheterization (intermittent preferred)
