Physiology of Urinary Elimination
Kidneys- Regulates fluid and acid-base balance
Ureters- Junction between the kidney and the bladder
Bladder- Hollow, muscular organ that serves as the
reservoir for urine
Urethra- Extends from bladder to urinary meatus
(opening)
90
Altered Urine Production and treatment
Polyuria--Excessive urination
Oliguria--the production of abnormally small amounts of urine.
Anuria--no urine
Treatment= Dialysis
Peritoneal--uses the peritoneum (in abdomen) as the membrane through which fluid and dissolved substances are exchanged with the blood
Hemodialysis-- Remove extra salt, water, and waste products so they don't build up in your body. Keep safe levels of minerals and vitamins in your body
91
Nocturia
-night peeing-limit nighttime fluid
92
Urgency
-sudden strong need-provide routine for peeing
93
Dysuria
-painful-assess constantly
94
Enuresis
-bed incontince- regular toileting schedule, providing privacy and comfort during toileting, encouraging adequate fluid intake, assisting with mobility and positioning, monitoring urinary output
95
Urinary Retention
--cant empty all urine in bladder-double voiding, schedule, catheter,
96
Neurogenic Bladder-
lack bladder control due to a brain, spinal cord or nerve problem-cath,drugs,therapy,manual help
97
Urinary Incontinence
t
e
Transient-Acute-urine leakage that is caused by a temporary (transient) situation-
Established-Chronic-loss of bladder control
98
Types of Urinary Incontinence:
Reflex-urine leaks without a warning or urge to urinate
Stress- leaking urine during physical activity that increases abdominal pressure, such as coughing, sneezing, laughing, or exercise
Total-bladder cannot store urine at all
Urge-involves sudden compelling urges to void and results in involuntary leakage of urine
99
NI for urinary incontince
promoting adequate fluid intake, maintaining normal voiding habits, and assisting with toileting
