4. BLADDER AND BOWEL FUNCTION
Overview:
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
5. Structures and Functions Related To
Bowel Elimination
STRUCTURES AND FUNCTIONS
RELATED TO BOWEL ELIMINATION
DIGESTION
HTTP://WWW.MEDTROPOLIS.COM/VBODY.ASP
6. STRUCTURES AND FUNCTIONS RELATED TO
BOWEL ELIMINATION
Bolus with Ptyalin
HCL, Pepsin
Intrinsic factor
Mucus CHYME
Releases bile to Amylase released
duodenum
Absorption, secretion, Nutrients, electrolytes,
protection, elimination vitamins absorbed
Defecation process
7. Physiology of Defecation
Peristalticwaves move the feces into
the sigmoid colon and the rectum
Sensory nerves in rectum are
stimulated
Individual becomes aware of need to
defecate
Feces move into the anal canal when
the internal and external sphincter relax
8. External anal sphincter is relaxed
voluntarily if timing is appropriate
Expulsion of the feces assisted by
contraction of the abdominal muscles
and the diaphragm
Moves the feces through the anal canal
and expelled through anus
Facilitated by thigh flexion and a sitting
position
9. FACTORS AFFECTING BOWEL
ELIMINATION
Lifestyle
Personal habits
Nutrition and fluid intake
Physical activity
Culture
Norms of western culture
Age
Infancy
Elders
10. FACTORS AFFECTING BOWEL ELIMINATION
Physiological factors
Pregnancy
Motor and or sensory disturbance
Intestinal pathology
Medications
Surgery and anesthesia
Psychosocial factors
Anxiety
Depression
13. CONSTIPATION
A symptom not a disease
Decreased frequency of defecation
Hard, dry, formed stools
Straining at stools
Painful defecation
Causes include:
Insufficient fiber and fluid intake
Insufficient activity
Irregular habits
14. FECAL IMPACTION
Mass or collection of hardened feces in folds
of rectum that cannot be expelled
Passage of liquid fecal seepage and no
normal stool
Causes usually:
Poor defecation habits
Results from unrelieved constipation
Treatment
Removed manually
Must have physician order
Monitor patient for Valsalva reaction
15. DIARRHEA
Passage of liquid feces and
increased frequency of
defecation
Spasmodic cramps, increased bowel sounds
Fatigue, weakness, malaise, emaciation
A symptom of disorders affecting digestion,
absorption, and secretion of the GI tract.
Major causes:
Stress, medications, allergies, intolerance of
food or fluids, disease of colon
16. FECAL INCONTINENCE
Loss of voluntary ability to control fecal and
gaseous discharges
Generally associated with:
Impaired functioning of anal sphincter or nerve
supply
Neuromuscular diseases
Spinal trauma
Tumor
Nursing Considerations
Incontinence can harm a clients body image
Incontinence predisposes the skin to breakdown
17. FLATUENCE
Excessive flatus in intestines
Leads to stretching and inflation of
intestines
Can occur from variety of causes:
Foods
Abdominal surgery
Narcotics
18. ASSESSMENT OF BOWEL FUNCTION
History of bowel prior patterns
usual time
frequency of stool
past reliance on aids
Present status and pattern
Time
Characteristics of stool
Medications that may affect bowel functioning
sedatives
diuretics
antihistamines
19. ASSESSMENT OF BOWEL FUNCTION
Infection, trauma, or stress may affect
stool formation
Physical Abdominal Assessment
Inspection
Auscultation
Palpitation
determine abdominal discomfort
palpable obstruction would indicate need for rectal
exam
23. ABDOMEN
Subjective Assessments:
Any abdominal pain?
N/V?
Appetite good?
Last BM?
Stool formed/loose?
24. ABDOMEN-OBJECTIVE ASSESSMENT
Normal
soft
non-tender
non-distended
normoactive bowel sounds in all 4 quadrants
Normal bowel sounds
2-3 every 15sec or 10-30 every min
26. AIDS TO NORMAL BOWEL ELIMINATION
Fluid intake and fiber:
Adequate fiber
Adequate fluid intake
Upright posture
27. CONSTIPATION
Managing constipation:
Diet
25 -35 G of fiber + WATER!
Medications
Laxatives
cathartics
Enemas
high – cleanse entire colon
low – cleanse rectum and sigmoid colon
hypotonic and isotonic
– immediate large colonic emptying
hypertonic and mineral - fleets
28. FECAL INCONTINENCE
Assessment key factors:
Is the problem correctable or manageable?
What is the timeline or duration of
situation?
Any associated symptoms?
30. RELATED NURSING DIAGNOSIS
Risk for Deficient Fluid Volume
Risk for Impaired Skin Integrity
Low Self-esteem
Disturbed Body Image
Deficient Knowledge
Bowel Training
Ostomy Management
Anxiety
31. DESIRED OUTCOMES
Maintain or restore normal bowel
elimination pattern
Maintain or regain normal stool
consistency
Prevent associated risks such as fluid
and electrolyte imbalance, skin
breakdown, abdominal distention and
pain
32. NURSING CONSIDERATIONS
Promoting regular defecations
Teaching about medications
Decreasing flatulence
Administering enemas
Digital removal of a fecal impaction
(if agency policy permits)
Instituting bowel training programs
Applying a fecal incontinence pouch
Ostomy management
38. STOMA CARE FOR CLIENTS WITH AN OSTOMY
Normal stoma should appear red and may
bleed slightly when touched
Assess the peristomal skin for irritation each
time the appliance is changed
Treat any irritation or skin breakdown
immediately
Keep skin clean by washing off any excretion
and drying thoroughly
Protect skin, collect stool, and control odor
with an ostomy appliance
39. COMMON TESTS
Direct Visualization
fiber optic endoscopic instruments introduced through the
mouth or rectum to inspect integrity of mucosa blood vessels,
and organs.
UGI Endoscopy
Colonoscopy
http://www.swarminteractive.com/patient_ed_animations.html
40. COMMON TESTS
Fecal specimens
Ova and Parasites
Guaiac testing
Hidden (occult) blood
44. Urinary Elimination
Micturition
The process of emptying the bladder
Contraction of detrusor muscle
Increases pressure on bladder to produce urge to
urinate
Pressure overcomes the internal sphincter
Urine enters urethra
Requires relaxation of external sphincter
consciously relaxed or contracted
46. URINE FORMATION
Nephron
Functional unit of the kidney
Urine is formed here
Glomerulus
Tuft of capillaries surrounded by Bowman’s capsule
Fluids and solutes move across endothelium of the
capillaries into the capsule
Bowman’s Capsule
Filtrate move from here into the tubule of the nephron
47. Aids to Normal Urinary Elimination
Daily fluid intake
Urine produced = fluid consumed
Need 6 to 8 glasses per day of WATER
Activity
External sphincter is part of pelvic floor muscle
Tone needed to maintain voluntary control
Personal Habits
Relaxation
Distractions
48. STRUCTURES AND FUNCTIONS RELATED
TO FLUID ELIMINATION
Characteristics of normal urine:
Color
Clarity
Odor

57. LOSS OF URINARY CONTROL
Nursing ASSESSMENT of Urinary Incontinence:
Confirm factors related to episodes
Determine cognitive function and the ability of patient
to participate interventions
Make observations during caregiving regarding the
amount and frequency of loss of urine and situations
surrounding incontinent episodes
Assess abdominal and suprapubic palpation for
tenderness and fullness
Determine hydration status and possibility of
constipation
Ask specific questions regarding situations that lead to
urine loss
