Elimination Flashcards
What is defecation?
Bowel movement
What is micturition?
Urination
What is continence?
Purposeful control of urinary or fecal elimination
What is elimination?
Removal, clearance of matter. Excretion of waste productions
What is bowel elimination?
Passage of stool through the intestinal tract and dispelling the stool by mean of intestinal smooth muscle contraction (stool/feces)
What is urinary elimination?
Passage of urine through the urinary tract by means of the urinary sphincter and urethra
What is Anuria?
Absence of urine
What is dysurisa?
Painful urination
What is polyuria?
-multiple episodes of urination, w/diabetes
What is urinary frequency?
Multiple episodes of urination with little urine produced in a short period of time
What is urine hesitancy?
Urge to urinate exists but person has difficult starting urine stream
What is the main functional unit of kidney?
Nephron (contain blood vessels/renal tubules)
What are characteristics of internal vs external sphincter?
INTERNAL: smooth muscle, involuntary, prevent leaking
EXTERNAL: skeletal muscle, voluntary
What happens with increased peristalsis?
Less water absorbed, loose stool
What happens with reduced peristalsis?
More absorption and harder stool
What become weak in the elderly?
Muscles around the urethra, increase risk of incontinence
What are age related changes in elderly when it comes to elimination?
- decreased bladder capacity (400 -> 200-300)
- decreased estrogen in post menopausal women
- loss of smooth muscle in the bladder
- relaxation of the pelvic floor muscles
- Hypertrophy of the muscles in the urinary tract
- less responsive to ADH and less able to concentrate urine
- decreased time between urge to void and actual need
- proliferation of the prostate tissue
- diminished thirst perception
What is incontinence and what is a risk factor?
- loss of control of urine or bowel
- risk of skin breakdown, change in daily activities
What is urinary incontinence?
- distribution in the storage or emptying of the bladder with involuntary release of urine usually associated with dysfunction of the external or internal urinary sphincters
- light leakage to full loss
What factors can effect urine incontinence?
-depression, anxiety, cognitive impairments, acute injury, surgical procedures
Define the following terms of urine incontinence:
Stress, overactive bladder, urge, functional, overflow, mixed, transient.
Stress: leakage during small amounts of physical movement
overactive bladder: frequent and urgent (pee a lot)
urge:leakage at unexpected times (sleep)
functional: untimely urination b/c of physically disability, obstacles
overflow: leakage from full bladder
mixed: occurrence of stress and urge incontinence together
transient: leakage that occurs temporarily (medication/cold)
What is bowel incontinence?
Involuntary passage of stool and ranges from occasional leakage of stool while passing gas to complete loss of bowel control
What is retention?
Unintentional with obstruction, inflammation, ineffective neuromuscular activation within bladder or GI tract
What is urinary retention?
-incomplete emptying of bladder after urination
