27
Stress incontinence
Involuntary loss of urine by increased abdominal pressure | - ex: coughing
28
Urge incontinence
Frequency of urine in small amounts | - ex: UTIS's
29
Total incontinence
No control over urine at all | - ex: muscle related problems
30
Factors related to urinary incontinence?
- muscle function - bladder infection - impaired ability - environmental barriers
31

Unable to void Overflow incontinence Bladder stretches to its limits
32
Factors related to urinary retention?
post surgical clients, indwelling catheter recently removed, obstructions
33
how to measure urine output
empty urine into graduate, voiding urine hat or urinal from catheter
