changes in older adult (4)
glomerular filtration rate and kidney's ability to concentrate urine decreases resulting in nocturia.
changes in older adult (5)
loss of bladder muscle tone and capacity to hold urine leads to urinary frequency.
changes in older adult (4)
glomerular filtration rate and kidney's ability to concentrate urine decreases resulting in nocturia.

excessive urination at night
What is excessive output of urine a sign of
renal dysfunction,k kidneys cannot concentrate urine.
What effect does caffeine and alcohol have on urine output
(Inhibits adh release.)
what effect does a fever have on urine volume
Reduces it making it concentrated
what risk do spinal anesthetics have on urine output?
urinary retention.
because of decreased sese of need to void and inabliityh of bladder muscles and sphincters to respond.
swelling of lower abd and pelvis related to surger may cause what?
obstruct flow of urine-routine use of catheters.
stress response to sugery and anesthetics do what?
slow glomerular filtration rate, decreaseing urine output.
what do diuretics do
increase urine output
risk of urinary retention with what meds?
anticholinergics, antihistamines, belladonna alkaloids, and phenothiazines.
what do cholinergics do and name an example of one.
stimulates contraction of detrusor muscle to promete voiding and stimulates gi tract smooth muscle.

sweating, slaivation, vd, cramps decreased bp.
what does the medication pyridium do to urine
colors urine a bright orange to rust color
cholinergics, parasympathomimetics are used cautiosly with?
ulcers, gi or urinary obstruction, coronary artery bypass procedure, asthma, pregnancy.
cholinergics, parasympathomimetics are used cautiosly with?
ulcers, gi or urinary obstruction, coronary artery bypass procedure, asthma, pregnancy.
what medications are toxic to kidneys?
How to monitor them?
aminoglycoside, antiinfectives, chemotherapy.
monitor I and O, maintain hydration.
Cystoscopy can cause what?
what will happen?
urtehral edema and spasm of bladder sphincter.
pt may not be able to void. urine pass may be red or pink due to blood from trama.
what test requires clear liquids the evening before thest and laxatives to clear colon?
intravenous pyelogram.
what to do following iv pyelogram test
