00:00
At the beginning of this video,
I promised I would explain
how we use a urine dipstick
to identify a UTI.
00:08
So that's what we're going
to roll into next.
00:11
When you take the dipstick test
and you dip it in the urine,
we're watching for color changes
on those small boxes.
00:18
Now these three substance should
never be present in your urine.
00:23
So if one of these
three substance is positive
on the urine dipstick test,
you see the color change
at the appropriate time.
00:31
That means you need to follow up.
00:33
So if you have all three,
we have a really big deal.
00:36
But even if you have just
one of these three,
it's going to require you
to follow up and figure out
what's going on
with your patient.
00:45
So you see you've got
the title up there.
00:46
What should I be looking for?
First group, leukocytes.
Those are white blood cells.
00:54
Nitrites is our second group.
00:56
And the third one
is the presence of blood.
00:59
Okay.
Leukocytes, nitrites, and blood.
01:03
These are the three
most important things
I want you to be looking for.
01:07
If we're examining a patient's urine
for the presence of a
urinary tract infection.
01:13
Leukocytes, nitrites, and blood.
01:16
You may be saying,
"I got it."
Hey, I always want to use
repetition.
01:21
To help those things stick
in your brain.
01:24
We want you to study as you go.
01:25
So that's why
leukocytes, nitrites, and blood.
01:30
Now let's try a question.
01:31
This is a strategy
I always recommend
when you're studying.
01:34
Stop, pause, and think back
about what we've discussed.
01:38
So see if you can answer
this question.
01:40
I'm pretty sure you can.
01:43
How will I know if
leukocytes, nitrites, or blood
are present in the urine sample?
Right, the squares on the
urine test strip or the dipstick
will change colors to
indicate these are present.
01:58
Good job.
All right.
02:00
Use that as a strategy
while you're studying,
always pause,
reflect, and think back.
02:05
And we've done that for you.
02:07
The whole Lecturio team
works together
to help you with spaced repetition.
02:12
So make sure you're taking
advantage of those questions
that's been provided.
02:17
Here's another question for you.
02:19
Who is more likely
to have a UTI?
Now looking at the graphic,
you can see
we have a male urinary tract
and a female urinary tract.
02:28
Look at how those are made up.
02:30
Which one is longer,
which one is shorter?
You probably already know
that E. coli from your gut
is one of the most common causes
of a urinary tract infection.
02:41
So whose plumbing
seems to be more at risk?
Right.
It's the female.
02:47
In fact, UTI or
Urinary Tract Infections
are 50 times
more common in women.
02:54
Okay, they can range from cystitis,
which is inflammation, right.
02:59
A mild kind of disturbing
inflammation,
it's limited to the bladder,
or it can range all the way
to severe infections
of the kidneys.
03:07
So women are 50 times more likely
to experience a UTI.
03:13
You'll remember why
when you look at the length
of the urethras, right,
much much shorter.
03:18
So keep in mind,
you're likely to see female patients
more often with UTI.
03:24
And we talked about three important
dipstick tests for UTI.
03:28
Let's take a look at
leukocytes or white cells.
03:31
Leukocytes in your urine are a
sign of an inflammatory condition
in the kidneys or the urinary tract.
03:36
Remember, these guys
are the first responders.
03:38
when you have infection
they race right in
to try and address that infection.
03:44
Now, if you have a bacterial UTI,
you usually have leukocytes
in the urine.
03:49
Keep in mind bacterial infection
is just one type of UTI.
03:53
You can have fungal and yeast
and all kinds of nasty stuff.
03:56
But if it's a
bacterial infection,
you'll usually have
leukocytes in the urine.
04:01
Next up, Nitrites.
04:04
Now, I'm slowing down
and enunciating that very clearly,
because that second eye
makes a difference.
04:12
So you shouldn't have any nitrites
in the urine.
04:15
If you do, we've got a problem.
04:18
Nitrites in the urine
are the result of the conversion
of nitrates into nitrite.
04:24
And who does it?
Bacteria.
04:27
So bacteria in the urinary tract,
take nitrate
and convert it to nitrite
that will change on your
urine dipstick
and that means we likely have
a bacterial infection.
04:39
The third member of the trio
we're looking for is blood
but it's not quite as clear cut.
04:44
We do know that blood in the urine
can be a sign of a severe
urinary tract infection.
04:50
However, there's other reasons that
you might see blood in the urine.
04:55
For example,
if it's a female client,
it could be because
of menstruation.
04:59
So you want to be sure
to ask questions
do a clear assessment
of your patient
because you want to rule out
the possibility of menstruation.
05:06
But if you do see blood
in a patient's urine,
further investigation
is usually required at any time
a sample comes back positive
for blood.
