SLO: Urinary Elimination

Questions 2, 5, 8


  1. Describe the process of urination.
  2. Identify factors that commonly influence urinary elimination.
    1. Growth and development – children cannot voluntarily control voiding until 18-24 months, older adults may experience a decrease in bladder capacity
    2. Sociocultural factors – cultural and gender norms vary north Americans expect private bathrooms some cultures accept communal toilet facilities, social expectations can interfere with timely voiding
    3. Fluid intake – increased fluid increases urine production when electrolytes are balanced, alcohol decrease antidiuretic hormone and increases urine production
    4. Pathological conditions – DM, multiple sclerosis, and stroke can alter bladder contractility and ability to sense bladder filling. Prostatic enlargement can cause obstruction of bladder outlet causing urinary retention
    5. Medications – diuretics increase urinary output by preventing resorption of water and certain electrolytes, some drugs can change the color of urine. Hypnotics and sedatives may reduce the ability to recognize and act on the urge to void.
  3. Compare and contrast common alterations in urinary elimination.
  4. Identify nursing diagnoses appropriate for patients with alterations in urinary elimination.
  5. Describe characteristics of normal and abnormal urine .
    1. Normal – ranges from a pale straw color to amber depending on the patient’s fluid intake and urine concentration, urine appears transparent at voiding. Normal urine will appear cloudy if left standing.
    2. Abnormal – bleeding from the kidneys or ureter can cause dark red urine, some medications and foods can also change the color of urine. A patient with renal disease will have cloudy or foamy urine upon urination. DM or starvation can cause urine to have a sweet or fruity odor from the acetone
  6. Describe the nursing implications of common diagnostic tests of the urinary system.
  7. Discuss nursing measures to promote normal micturition and reduce episodes of incontinence.
  8. Discuss nursing measures to reduce urinary tract infection .
    1. Using infection control principles help prevent the development and spread of UTS. Following medical asepsis when carrying out procedures involving the urinary tract or external genitalia. Providing perineal hygiene is an essential component of care. Use proper hand hygiene at all times.

Bob Clark is a 70-year-old patient who had a total hip replacement today; he is now on the orthopedic unit in stable condition.

SLO: Bowel Elimination

Questions 5, 8


  1. Discuss the role of gastrointestinal organs in digestion and elimination.
  2. Describe three functions of the large intestine.
  3. Explain the physiological aspects of normal defecation.
  4. Discuss psychological and physiological factors that influence the elimination process.
  5. Describe common physiological alterations in elimination.
    1. Prolonged emotional stress alters the digestive system. During emotional stress the digestive process is accelerated, and peristalsis is increased. Side effects include diarrhea and gaseous distension. Many diseases of the GI tract are exacerbated by stress. If a person becomes depressed the autonomic nervous system may slow impulses that decrease peristalsis resulting in constipation.
  6. List nursing diagnoses related to alterations in elimination.
  7. Describe nursing implications for common diagnostic examinations of the gastrointestinal tract.

George Miller, a 68-year-old male who had a stroke 6 months ago, comes to the urgent care clinic complaining of abdominal pain and nausea. He lives alone in an assisted living complex. He was never married, and his only relative is a 70-year-old sister who visits him two to three times a week. She is independent and concerned that Mr. Miller is doing okay. Mr. Miller uses a quad cane to ambulate because of hemiplegia on his left side and eats his meals in the central dining room at the complex. The complex has no licensed health care workers. Sally Schmitt, a nursing student, is assigned to the urgent care clinic. Her assignment is to perform an initial assessment on Mr. Miller with the acute care nurse practitioner (ANP). While Sally takes his history, Mr. Miller tells her that he has not had a bowel movement in 4 days. On physical examination, Mr. Miller’s abdomen is hard and he has hyperactive bowel sounds. The ANP determines that Mr. Miller has constipation and has a fecal impaction.

  1. Sally is to remove the impaction from Mr. Miller. Sally knows that it is not good for Mr. Miller to strain for a bowel movement. Why could straining cause concern for Mr. Miller?

Answer: straining while having a bowel movement causes the veins in the folds of the intestine to become distended from pressure. This distention results in hemorrhoid formation.

  1. Mr. Miller is also to have a tap water enema to promote bowel evacuation. After getting her equipment ready, Sally should position Mr. Miller in what position on the table?

A. Right side-lying position with his left knee flexed
B. Right side-lying position with his right knee flexed
C. Left side-lying position with his right knee flexed
D. Left side-lying position with his left knee flexed


  1. Mr. Miller’s sister has come with him to the urgent care clinic and asks Sally what could have caused Mr. Miller to get so constipated? Sally should explain that constipation can be caused by which factors? Select all that apply.

A. Ignoring urge to defecate
