Urinary System, Fluids and Electrolytes Flashcards
(109 cards)
Straw colored urine with mild odor
normal urine spec gravity 1.010 to 1.050
Cloudy Urine
may indicate the presence of large amts of protein, blood, bacteria and pus
Dark urine
may indicate hematuria, excessive bilirubin or highly concentrated urine
unpleasant or unusual odor
infection or result from certain dietary components or medication
Urinary Infection
heavy purulence and presence of gram-neg and gram-pos
Hematuria
Blood in urine
small amt: infection, inflammation, or tumors in urinary tract
large amt: increased glomular permeability or hemorrhage
proteinuria / albuminuria
leakage of albumin or mixed plasma proteins into filtrate due to inflammation and increased GFR
bacteriuria
Bacteria in urine
infection in urinary tract
Urinary casts
microcopic sized molds of teh tubule, consisting of one or more cells, bacterial, protein and others
indicated inflammation of kidney tubules
specific gravity
indicates ability of tubules to concentrate urine
low spec gravity = dilute urine (with normal hydration)
high spec gravity = concentrated urine (with normal hydration
Glucose and ketones
found when diabetes mellitus is not will controlled
High serum urea or serum creatinine
indicate failure to excrete nitrogen wastes
caused by decreased GFR
Metabolic acidosis
indicates decreased GFR
failure of tubules to control acid-base balance
Anemia
indicates decreased erythopoietin secretion and/or bone marrow depression
Electrolytes
depend on related fluid balance
antibody level
antistreptolysin O or antisteptokinease titers
used to diagnose poststrep. glomerulonephritis
Elevated renin levels
indicate kidney as a cause of hypertension
incontinence
loss or voluntary control of the bladder
enuresis
involuntary urination by child age older than 4
-often related to developmental delay, sleep pattern or psychosocial aspect
Stress incontinence
common in women
increased intra-abdominal pressure forces urine through sphincter
coughing, lifting, laughing, multiple pregnancies
overflow incontinence
incompetent bladder sphincter
older adults
- weakened detrusor muscle may prevent complete emptying of bladder
spinal control injuries or brain damage
- neurogenic bladder - may be spastic or flaccid
- interference with CNS and ANS voluntary controls of the bladder
Retention
inability to empty the bladder
may be accompanied by overflow incontinence
spinal cord injury at sacrallevel blocks micturition reflex
may follow anathesia
Urinary Tract infections
very common infections urine is an excellent growth medium lower urinary tract infections - cystitis (bladder) - urethritis (urethra) upper urinary tract infections - pyelonephritis (Kidneys, upper tract) common causative organism - e. coli
People who get UTIs
Most common in women - shortness of urethra and proximity to anus Older men - prostatic hypertrophy -urine retention Congenital abnormalities in children Other common predisposing factors - incontinence -retention of urine -direct contamination with fecal material
