Exam 3 Flashcards
why are women at a greater risk for UTI?
shorter urethra
- developmental considerations
- food and fluid intake
- psychological variables
- activity and muscle tone
- pathologic conditions
- medications
factors affecting micturtion
Toilet training 2-3 years old, enuresis (bed-wetting)
May see child potty trained sooner also
children developmental considers (micturtion)
Nocturia: urinating at night
Increased frequency
Urine retention and statis
Voluntary control affected by physical problems
effects of aging on micturtion
- anuria
- bacteriuria
- dysuria
- enuresis
- frequency
- hematuria
- hesitancy
- incontinence
- nocturia
- oliguria
- polyuria
- proteinuria
- urgency
problems associated with changes in voiding
urine output <50 mL/day
possible etiology: acute or chronic renal failure
anuria
what is the normal volume of urine that should be voided per hour?
30 mL
bacterial count >100,000 colonies/mL in the urine
etiology: infection
bacteriuria
painful or difficulty voiding
etiology: lower UTI, inflammation of the bladder or urethra, acute prostatitis, stones, foreign bodies, tumors in bladder
dysuria
involuntary voiding during sleep
often seen in pediatric pt
etiology: delay in functional maturation of CNS
enuresis
frequent voiding - more than every 3 hr
frequency
RBC in urine
hematuria
delay, difficulty in initiating voiding
hesitancy
involuntary loss of urine
incontinence
awakening during the night to urinate
nocturia
urine output <0.05 mL/kg/h
oliguria
increased volume of urine voided
polyuria
protein in urine
proteinuria
strong desire to void
urgency
which conditions relate to urinary output
1) polyuria
2) anuria
3) oliguria
which conditions relate to urine composition?
1) hematuria
2) bacteriuria
3) glucosuria
4) proteinuria
1) intake 3L of water
2) generally recommended to drink 6-8 cups of water per day - consider indirect intakes of water
3) normal output is 1 mL/kg/hr; oliguria is 0.5 mL/kg/hr
urine output
multiply weight (in kg) by 0.5 and subtract amount voiding
if weight is given, then do based on pt weigh to see if urine output is normal
if UO is given, but no weight, then go on general basis that 30 mL (or CC) /her is normal
how to calculate urine output
fluids can be lost through many sources: urine, feces, seat, evaporation via lungs
intake: water, coffee, juice, tea, IV, foods
