elimination Flashcards
what does urine output of less than 30mL/hour indicate?
renal impairment or hypovolemia (dehydration or blood loss)
what does cloudy urine indicate
bacteria or WBCs
causes
urinary retention
blockage from an enlarged prostate, renal/urinary stones
symptoms
UTI
symptoms:
- dysuria
- urgency
- frequency
- suprapubic tenderness
- incontinence
- cloudy/foul smelling urine
- blood
- in elderly: fatigue, confusion, delirium, incontinence, falls
risk factors
UTI
- indwelling catheter
- urinary stasis/retention
- poor perineal hygeine
- incontinence
- constipation
- urinary tract stones
- obesity
- pregnancy
- menopause
- conditions that compromise immune response
- habitual delay in voiding (teacher’s/nurse’s bladder)
lower vs upper UTI
lower: urethra + bladder, can cause cystitis
upper: ureters + kidneys, can cause pyelonephritis
causes
urge incontinence
aka overactive bladder
damage to brain, spine, nerves that innervate the bladder, diabetes mellitus, neuro disease/trauma, changes to bladder lining + muscle with aging
causes
stress incontinence
urethral sphincter/pelvic floor muscles damaged (can’t hold in urine) - coughing + laughing puts pressure on bladder = leakage
causes
overflow incontinence
urine blocked from flowing out of bladder by prostate, tumors, stones, scar tissue, prolapsed uterus/bladder (bladder distended - pulls urethra open - urine leaks out)
what is it
ureterostomy
ureters attacher to abdomen surface (urine flows directly into pouch)
continent internal ileal reservoir
Kock pouch: continent internal ileal reservoir created from segment of ileum + ascending colon
ureters are implanted into the side of the reservoid, special nipple valve attaches reservoir to skin
once healed patient can self-catheter at 4-6 hour intervals
sigmoidostomy
urine diverter to large intestine (no stoma)
urine is excreted with bowel movements (can result in incontinenve)
conduits
ureters are implanted into a segment of the ileum/colon (abdominal stoma formed)
urine flows in the conduit and out of stoma by peristalsis
how does age affect peristalsis
infants have smaller stomach + more rapid peristalsis, older adults have difficulty chewing + swallowing, decreased peristalsis
perineal muscle tone + anal sphincter weaken with aging (can lead to bowel incontinence)
diet effects on bowels
fiber = bulk for fecal matter
gas-forming foods (cabbage, beans, broccoli) = bowel distention + increased motility
whole grains + fresh fruit/veggies = promote peristalsis
adequate fluids promote elimination
