Urinary Elimination Flashcards
if someone is fluid deficit what do we do
give fluids
when someone has urinary issues what do we want to keep an eye on
I&O
what is the main involuntary muscle of the urinary system
detrussor muscle
what is included under voluntary control
imitating
stoping
interrupting
what is the minimum normal urine output
30mL/hr
can we control the internal sphincter
no
internal sphincter is controlled by
neurogenic
external sphincter is controlled by
you
- able to control this one
how does age influence urination
decreased ability to concentrate urine
decreased bladder tone
decreased bladder contractility
neuromuscular/cognitive problems
what does it tell you that older adults have decreased ability to concentrate urine
frequent getting up throughout the night which is a fall risk
- able to concentrate urine allows us to not have to go at night
what does it tell you that older adults have decreased bladder tone and bladder contractility
the bladder does not empty fully so they will have statsis of urine which leads to a UTI
what does it tell you that older adults have neuromuscular/cognitive problems
they are not aware they have to do
how can food and fluid intake affect urination
decreased drinking could lead to increased sodium
what do we want fluid intake at
2-3L
what are some pathology that can affect urination
renal disease, diabetes
what are some medications that can increase urine output
diuretics
what should we ask about voiding history
how often do you go
are you routinely going
who might be at risk for high post void residuals
BPH
what do we use to confirm how much fluid is in post void residual
bladder scanner
what is a normal post void residuals
> 50mL
what can be an assessment of urine include
color
clarity
odor
volume over 24 hour period
specimens
UA
urine analysis
how much do we need for a UA
10mL
is a UA a gross or specific
gross
what does a UA tell us
WBC, RBC, sugar, protein
if we notice a possible problem on the UA what will we order next
urine culture and sensitivity
how much do we need for a urine culture and sensitivity
3mL
CCMS
clean catch mid stream
how do we collect a CCMS in a patient with a catheter
specimen port
how do we collect a CCMS on a patient with no catheter
good peri care
start
stop
start and collect
stop
finish
why do we want the patient to pee at first when getting a CCMS
gets rid of any contaminants
if we have a patient with no catheter and they cannot perform a CCMS what do we do
straight Cath for the procedure
how do we do a 24 hour urine sample
at the time the 24 hour starts have patient void because this urine was now produced during that 24 hour. at the end of the 24 hour collect that urine because it was produced in that 24 hour
what happens if we dump a void for a 24 hour urine sample
start over
what can a 24 hour urine sample tell us
renal function
creatine
clearance
is culture and sensitivity a sterile procedure
yes
BUN normal
8-23
what does BUN measure
can the kidneys remove urea from blood
nitrogen in blood that comes out in urine
how well the kidneys work
what is urea
protein broken in body
who might we see a high BUN in
decreased kidney function or dehydrated
is creatine a more refined or gross test
refined
