Transcript

  • 1. NURSING FUNDAMENTALS FOCUS IX Elimination Needs
  • 2. OBJECTIVES:SOLID Describe the physiology of stool formation and the elimination process. List the common problems of bowel elimination. Discuss nursing responsibilities involved with each problem. Define and explain some of the basic but important measures to promote normal bowel elimination. Compare and contrast the different types of altered means of bowel elimination. Identify the procedures/technical skills and related nursing responsibilities. Identify the common diagnostic procedures related to the bowel elimination need and the associated nursing responsibilities
  • 3. OBJECTIVES:FLUID Describe the normal micturition process mechanism. Discuss common conditions /situations responsible for a disruption in the normal micturition process. List the commonly recognizable signs (behaviors) indicating a disruption in urinary elimination. Compare and contrast the altered means of urinary elimination and explain the related procedures and nursing responsibilities. Report the basic but important nursing interventions to promote normal urinary elimination. Examine the common diagnostic procedures related to urinary elimination and the associated nursing responsibilities.
  • 4. BLADDER AND BOWEL FUNCTIONOverview: The human body eliminates waste of metabolism through urine and stool. Normal function depends on these factors: - anatomic integrity - intact neurologic components for both voluntary and synergistic emptying - a predictable pattern of waste production - physical and mental ability and the psycho-social willingness to carry out toileting related tasks
