Elimination
Basic Principles
Wash Hands & Wear Gloves
Infection control, your protection & your
client’s protection
Privacy
Embarrassing
Positions for urination
Independence
Functions of Urinary
System
Remove wastes from blood to form urine
Remove nitrogenous waste products of
cellular metabolism
Regulates fluid and electrolyte balance
The nephron = functional unit of the
kidney and forms the urine
Goal of Urinary System
To maintain chemical homeostasis of the
blood.
Filtration by the Nephrons
H2O, glucose, amino acids, urea, creatinine,
major electrolytes
Not normally large proteins or blood cells
Proteinuria is a sign of glomerular injury
Normal adult 24hr output = 1500-1600ml.
Overview of Urinary
System
Kidneys
Bean shaped organs
Either side of vertebral columns T12 – L3
Right kidney lower due to liver
Urine produced with filtration of blood
through nephrons
Major role in fluid & electrolyte balance
Ureters
Connect kidneys to bladder
10 -12 in length, ½ in diameter in adult
Peristaltic waves
Renal colic
Micturition
Bladder
Distensible, muscular sac
Reservoir for urine ( approx. capacity =
600mls )
Organ of excretion ( norm. voiding= 300mls)
Lies in pelvic cavity behind symphysis pubis
Urethra
Short, muscular tube
Urine from bladder to meatus and from the
body
Female 4-6.5cm (1 ½ - 2 ½ in.) length
Male 20cms ( 8 in.)
Urinary and reproductive systems
Meatus
External opening of the urethra, male &
female
The need to void is a conscious
awareness
Life Cycle Changes
Infants & children
Unable to concentrate urine b/c kidneys are
immature
Urine is light yellow
Void frequently
Voluntary control @ 24mos. when
neuromuscular structures develop
Adult
1500 – 1600 mls urine/24hrs
Concentrates urine – normal is amber
colored
Nocturia
Not usually
Decreased renal blood flow during rest
Ability to concentrate urine
Elderly
Micturition impaired
mobility
Diseases, alzheimer’s, CVA
Physiological age related changes
Bladder loses muscle tone and capacity
Kidneys lose ability to concentrate urine
Bladder loses muscle strength
Common Problems
Urinary Retention
Accumulation of urine in the bladder
Inability to empty
Pressure, discomfort and tenderness
Residual Urine = urine retained in the
bladder after voiding
Incontinence
Loss of voluntary control to void
Infection, nerve damage to bladder or brain, spinal cord
injury, or aging process
Total incontinence = no control
Stress incontinence = sm. amts. Urine excreted
involuntarily with coughing or laughing
At risk for skin breakdown related to acid urine
next to skin.
Adult Diapers or Attends
Frequency & Urgency
Nocturia
Enuresis – involuntary discharge of urine
Nocturnal Enuresis
During sleep
Bed-wetting children 5yrs and older
Oliguria
30mls/hr or 720 mls/24hrs
Renal anuria
cessation of urine production
100mls/24h
Promoting Healthy Urinary
Elimination
Urinate as soon as the urge is felt
Avoids stasis and distention
Prevents urgency, infection, and
incontinence
Drink about 2liters fluid/day
Limit Na, caffeine, and alcohol
For people with Nocturia
fld. Intake in the p.m.
caffiene and alcohol
Void before bedtime
For Women
Wipe perineum front to back
Void soon after intercourse
Wash hands
Pelvic – floor strengthening exercises (Kegel
Exercises)
Client Education
S & S of infection
Fluid intake ( if no restrictions 2-5 L/day )
Perineal hygiene
Meds. & side effects on urination, color,
and volume
Facilitating Micturition
Nursing Measures to promote voiding in
people who are having difficulty:
1.
2.
3.
4.
5.
Privacy and natural position
Providing commode or bathroom
Running water
Warm water to dangle fingers
Warm water over perineum ( measure if on
In/Out )
6. Gently stroking inner thighs or pressure
to symphysis pubis
7. Pain relief
Warmth to the bladder & perineum relaxes
muscles & facilitates voiding. ( Sitz bath
or warm tub )
If unsuccessful- urinary catheterization
may be indicated
Promoting complete bladder emptying
Prevention of infection
Good perineal hygiene
Adequate fld. Intake
Dilutes urine & flushes urethra
Acidifying urine ( inhibits microorganisms)
Cranberry juice, whole grain breads, meats,
eggs, prunes and plums.
Indwelling Catheter Care
Goal- prevent infection & maintain
unobstructed flow of urine. Monitor
for problems.
Perineal hygiene @ least 2x/day and
prn
Do not advance catheter further into
urethra during perineal care
Catheter Care
Fld intake (3L/day )
Handwashing and Gloves
Positioning
Urine bag
Tubing
Bowel Elimination
Function- excrete/eliminate waste
products of digestion.
Maintaining normal bowel elimination is
essential to health and efficient body
functions.
GI System
Small Intestine
Absorption nutrients & electrolytes
20 ft length, 1 in. diameter
3 sections
Duodenum
Jejunum
Ileum
GI
Large Intestine
Absorbs H2O and electrolytes
Temporarily stores waste products
Main function is elimination
5 – 6 ft. length, 6 – 7 cm. diameter
Cecum
Ascending colon ( Right side )
Transverse colon
Descending colon
Patterns through life cycle
Babies: 3 – 6 BM’s/day
Children:
Neuromuscular structures not developed
until 15 – 18 mos.
Voluntary control 2 – 3 yrs.
Pregnant women prone to constipation
Pressure on abd. Organs
Iron supplements
Elderly prone to constipation
Slowing of peristalsis
Determinants affecting
elimination
Dietary patterns & fld. Intake
6 – 8 glasses H2O/day ( 1400- 2000mls )
fld.
Liquifies stool
Dietary fiber stimulates peristalsis
Soft stool
Factors affecting
elimination
Fiber ( undigestible residue ) provides
bulk
Absorbs fluid
Increases stool mass
Bowel wall stretches
Peristalsis stimulated
Defecation results
Factors affecting
elimination
Personal habits
Busy schedule, postpone BM, constipation
Activity & exercise
Immobile
activity in colon
Medications
Laxatives
Narcotics with codiene
Factors affecting
elimination
Emotions
Anxiety
peristalsis & diarrhea
Depression
Pain
Surgery
Anaesthetic causes temporary cessation of
peristalsis
Direct manipulation of the bowel stops
peristalsis
Common Problems
1. Constipation – difficult passage of hard,
dry stool; infrequent movements
2. Fecal Impaction – unrelieved
constipation, feces wedged in rectum,
no BM usually 3days, oozing of
diarrheal stool develops
3. Diarrhea- # liquid stool
4. Flatulence – abd. Distention & pain
Common Problems
Incontinence – inability to control
passage of stool
Hemorrhoids
Dilated engorged veins
Increased pressure when straining
Internal / external
Bleeding
Daily BM Not essential.
2 / week a concern
Defecation pattern
BM, Stool, Feces, Defecate – all mean
waste products expelled via the bowel

Procedure for Peri Care
Catheter –
Q 8 hrs.
Clean perineum & 2in. Of catheter
No powders / lotions
Avoid advancing catheter
Keep urine drainage bag off floor but below
level of bladder
Empty bag Q8 – 12hrs or when bag is full,
remember to mark amt. Emptied on In/Out
sheet
Avoid use of baby powder/ cornstarch
No medicinal purpose
Can form clumps or will cake in creases
Use vaseline/ zincoxide as skin barrier for
incontinent clients
Suppository
Administration
Check physician’s order, protocol
Left Lateral position
Gloves
Lubication
Hold with thumb and index finger
Insert with index finger (3 – 4”) never
force
Deep breath = relaxes anal sphincter
Caution
Vagus nerve stimulation can cause heart
rate to slow – avoid excess manipulation
Enema Administration
Main purpose
Promotion of defecation, stimulate peristalsis
The fluid breaks up fecal mass, stretches the
rectal wall & initiates the defecation reflex
Types of Enemas
Cleansing Enemas
Tap Water
Hypotonic
Used only once
Electrolyte imbalance
Water toxicity
Circulatory overload ( concentration gradient)
Normal Saline
Used when more than one enema is
needed
Safest
Isotonic
Large volume to distend bowel
Hypertonic Solution
Smaller volume of fluid
Draws from surrounding tissue into bowel to
soften stool and stimulate peristalsis
Fleets – sodium phosphate
Low volume, concentrated solution
Soap suds
Less common
Soap irritates the bowel
5 – 15 mls. Castile soap in 1000mls warm
water
Oil Retention
Oil based solution
Lubricates the rectum and colon
Softens stool, easier to pass
Retain 1 –2 hrs if possible
Follow with cleansing enema
Medicated
Instill meds.
Rectal mucosa absorption
Ex. – Kayexalate to K (potassium).
Absorbs K from the intestinal tract
Volumes for Enemas
Large Volume
500 – 1000mls.
Container 12 – 18 in. above the bowel
Lg. Volume stimulates & causes evacuation
of stool
Small Volume
500 mls.
Container 12 in.above bowel
Volumes for Enemas
Pre packaged
Fleet 150mls
Microlax 5mls
Hypertonic solution
User friendly
Hold for 5min.
Oral Fleet
Prepackaged used more than large
volume because:
Works
Less risk for electrolyte imbalance
Rapid administration
Less discomfort and distention
Convenient and quick
Physician’s order reads “ enemas to
clear”
No more than 3 total given
Return solution will be highly colored but no
solid stool
Isotonic solution (normal saline)
Excess enema use seriously depletes fluid
and electrolytes
Procedure for Enema
Administration
Confirm Dr’s order, prepare client, verbal
consent, equipment, privacy
Left lateral position ( fld. Flows by gravity)
Drape, pad under buttocks
Warm solution- stimulates peristalsis
Hot sol’n burns mucosa
Cold sol’n causes cramping
Procedure for Enema
Administration
Prime tube
Lubricate tip
Glove
Insert 7 – 10 cm.(3-4in) adult
Do not force
Deep breath
Guide toward umbilicus
Procedure for Enema
Administration
Container at appropriate height
Lg. = 12 – 18in
Sm. = 12in
1000mls takes ~ 10 min to instill
Higher the bag – greater the pressure
C/O discomfort, lower bag, slow infusion,
stop, then start again
Remain side lying to retain 5 – 10 min. or
as long as possible
Procedure for Enema
Administration
Assist to bathroom or give bedpan
Evaluate results
Document
Type & volume of enema
Color, amount, consistency of fecal return
Hygienic measures for client
Wash Hands
Ostomy Care
Certain diseases require surgical
interventions to create an opening into
the abdominal wall for fecal and urinary
elimination
Enterostomy – the surgical procedure
performed to produce the artificial
stoma.
Definitions
Ostomy = opening made to allow passage of
urine or stool
Piece of intestine is brought out onto the client’s
abd.
Lacks nerve endings
Doesn’t hurt to touch but has other implications
Stoma = mouth like opening in the abdominal
wall to drain urine or stool
Effluent – drainage from stoma
Bowel ostomies
Cancer ( Ca)
Drain fecal material
Consistency depends on location
Higher up = more liquid
Greater risk skin irritation b/c concentration
of digestive enzymes
Ileostomy
End of small intestine
By passes lg. Intestine = freq. Liquid stools
Colostomy
Large intestine
More solid stool
Ostomies may be permanent
More common
temporary
Rest the bowel
Crohn’s
Urinary Ostomies
Provide drainage of urine that bypasses
the bladder = Urinary Diversion
Ureterostomy
Ureter to abd. Wall
Lt., Rt., Bilateral
Ileal Conduit
6 – 8 in. ileum
1 end for external opening
Other end closed off
Ureters implanted into this piece of bowel
Pouch
Urine will have shred of mucus b/c bowel
still produces same
Concerns
Infection
Sterile ureters provide opening into system
Skin Breakdown
Continuous drainage
Moisture on skin
Replace urinary pouch q 2-3 days
Pouching an Enterostomy
Effluent ( drainage ) may begin immediately
Collects all effluent
Protects the skin
Stoma should be moist and reddish pink (same
as other mucus membranes)
Flush to skin or bud-like protrusion
Black, purple, dry = inadequate circulation
Pouch with Skin Barrier
Comfortable fit
Cover skin surrounding stoma
Good seal
Post-op pouch should allow for visibility
of stoma
Types of pouches and skin
barriers
One Piece Pouching System
Skin barriers preattached, precut, custom fit
Two Piece System
Skin barrier with flange ( plastic ring)
Corresponding size pouch
Assess stoma
Measure correct size
Change q 3-7 days
Empty 1/3 to ½ full, expel flatus prn
Steps to Care for
Ostomies
Supine position
Wash hands, glove
Remove pouch & skin barrier, push skin
away from barrier
Cleanse peristomal skin gently with warm
tap water and clean cloth
Do not scrub, Avoid soap ( residue- pouch
won’t adher)
Steps to Care for
Ostomies
Correct sizing
Cut opening 1/16 – 1/8 larger than stoma
Remove backing
Ileostomy- apply thin circle barrier paste
around opening of pouch and allow to dry
(if creases or bumps use barrier paste to
even surface for pouch application)
Steps to Care for
Ostomies
Pouch should point to client’s knees
Maintain gentle finger pressure around
barrier for 1-2 min.
Picture frame flange with non allergic
paper tape
Ostomy deodorant for pouch
Tub bath or shower
Steps to Care for
Ostomies
Normal stoma oozes blood if rubbed
Actual bleeding into pouch is abnormal
Pouch covers are available
The client will be watching the nurse
during ostomy care to gage reaction.
Be conscious of facial expression &
nonverbal cues
Steps to Care for
Ostomies
Education
Counseling
Body image
Self care
Fear of rejection
Sexual function
Powerlessness over bowel regulation
