Review structure and
function of urinary/ renal system |
kidneys remove waste from
blood and forms urine via the nephron. the ureters transport urine to the bladder leaves body thru the urethra |
|
Define
micturition |
the act of urinating
prevents reflux of urine from the bladder into ureters |
|
Factors that influence
urinary elimination |
dz, socio-cultrual,
psychological, muscle tone, fluid balance, surgical procedures, meds |
|
Expected range of
urinary output of an adult per hour |
per hour 30-300 mL
per 8 hr shift 240-2400 mL |
|
Normal
characteristics of urine |
pale straw color to amber
depending on concentration should be transparent should have its own odor |
|
normal anatomical
changes r/t fluid waste elimination in senior adult |
Increase in age - decrease
in size/wt of kidneys. Decrease in renal blood flow. bladder, urethra, ureter have decrease in elasticity/muscle tone. urinary sphincter weakens. Older women at risk for irritation, infection, incontinence. vag dry, thin men - freq, urg, prostate hypertrophy |
|
Psychological
and emotional aspects of incontinence |
Embarrassment, shamefull,
affects pts dignity, privacy |
|
Dysuria
Frequency |
Dysuria - painful/diff
urination Frequency - increased incidence of urinating, acutely inflammed bladder |
|
Urgency
Hematuria |
Urgency - strong desire to
urinate, acute bacterial infec. Hematuria - blood in urine ca in GU tract, UTI, renal dz |
|
Retention
Incontinence |
Retention - inability to void
even though bladder seems full s/p pelvic sx, childbirth Incontinence - inability to voluntarily control d/c of urine. bladder infec, inj to external sphincter |
|
Stress
Incontinence |
involuntary urination with
increased pressure when you sneeze or cough for exp. weakness of sphincter control |
|
Nocturia
Polyuria |
Nocturia - freq of urination
at night, renal dz, bladder obstruction, chf, dm Polyuria - large volume/amt of urine at a given time, dm chronic renal failure, excess fluid intake |
|
Anuria
Oliguria |
Anuria - no urination. output
in 24 hrs < 100 mL. acute renal failure, esrd, obstruction Oliguria - diminished amt of urine. severe dehydration, shock, kidney dz, esrd |
|
Most frequent
nosocomial infection |
hospital acquired UTI's.
due to catheterization and surgical procedures. most common cause e-coli |
|
UTI
|
inflammation of urinary tract.
bacterial infect. most common. can be classified as upper or lower. complicated or uncomplicated. |
|
Incontinence
|
uncontrolled or involuntary
loss of urine that is of sufficient magnitude to be a problem. caused by confusion, depression, infection, meds |
|
Obstruction
|
any anatomic functional
condition that blocks or impedes the flow of urine. may be congenital or acquired. diverticula, tumors, growths |
|
Phys. exam methods
to assess urinary tract |
Inspection - changes in skin,
abd, state of health Auscultation - abnrml murmur over aorta or renal arteries could indicate impaired flow Palpation - kidneys, bladder Percussion - tenderness in flank area may be detected |
|
Urinalysis
|
Color: pale yellow to amber
Appearance: clear to hazy Smell: aromatic Specific gravity 1.010-1.025 pH: average 5 and 6 * Glucose: negative * Ketones: negative * Blood: negative * Protein: negative * Nitrate for bacteria: negative * Leukocyte-negative * Casts: negative * Red blood cells * White blood cells |
|
24 hour urine
|
reveals how the kidney adjusts
to changing physiologic needs over a long period. Substances excreted by the kidney are not excreted at the same rate or in the same amounts during different periods of day and night |
|
BUN
Creatinine |
BUN and creatinine are waste
products filtered out of the blood by the kidneys. Increased concentrations in the blood may indicate a temporary or chronic decrease in kidney function. BUN 10-30 Creat 0.5-1.5 |
|
BUN/Creatinine
ratio Potassium |
bun/creat ratio 10:1
K+ 3.5-5.3, in renal dz first electrolyte to become imbalanced |
|
CBC
|
used as a broad screening test
to check for such disorders as anemia, infection, and many other diseases Hgb - amount of O2 carrying protein in the blood. Hct - amount of space RBC's take up in blood platelet count # of platelets in a given volume of blood. |
|
WBC
|
count of the actual number of
white blood cells per volume of blood norm 4k-11k |
|
Goals or interventions
for patient care that promote self-care urinary elimination |
Promoting habits, normal
micturition, stimulating micturition reflex adequate fluid intake complete emptying of bladder privacy |
|
In + out cath
|
straight cath, introduced
into bladder long enough to drain bladder 5-10 min can repeat if necessary, but increases risk of infection |
|
Indwelling cath
|
foley cath - remains in place
for a longer period of time until a pt is able to void completely and voluntary |
|
Suprapubic cath
|
surgical placement of a cath
thru the abd wall above the symphasis pubis and into the urinary bladder |
|
Plan/assessment/care
for pts with cath |
prevent infection
maintain unobstructed flow perineal hygiene hygiene at insertion point fluid intake |
|
Fluid intake
|
clients with normal renal
function require 2000-2500 mL fluids/day 1200-1500 mL is adequate |
|
Pelvic exercises
|
kegels - used to manage
stress, urgency, or mixed urinary incontinence. strengthens pelvic floor muscles |
