00:01
Now we're ready for what I call
Professor Lawes' big three.
00:05
I know that's all
interesting information
and you love to
learn that's cool.
00:08
I love it that were hanging out.
00:10
But what really matters is
you're wanting me to know
how does this make a
difference on my test scores?
That's what I'm
here to help you do.
00:17
So the big three
questions I have is
why does a nurse
need to know this?
How does it keep a patient safe?
And how do I apply
this information
to an exam question?
That's the one we
all want to know.
00:31
So let's take the information
we just talked about
and let's walk through
these big three.
00:36
Ready?
All right, number one.
00:39
So when we're thinking about
post streptococcal glomerulonephritis,
why does a nurse
need to know this?
Well, you need to know this
because we need to identify
that strep infection early
because we want to make
sure that they get treatment
they might get the right
antibiotics that they need
and hopefully prevent the
progression of the infection
turning into PSGN.
01:01
Remember patients with strep or
impetigo at risk to develop it.
01:04
So we want to be on the lookout
when we're taking care of these
patients or when that's diagnosed
because remember
glomerulonephritis equals
decreased kidney function
and a lower GFR,
a lower glomerular filtration rate.
01:19
Okay, so why do we need
to know this information?
Because you need to
know what to watch for.
01:26
In a test question,
but most importantly
in real life patients.
01:31
Now number 2.
01:32
How does it help me
keep a patient safe?
See these are the key questions
to ask yourself to check
your learning on any topic.
01:40
I'm showing you how to do it
on acute glomerulonephritis,
but you can add this
to any of your topics.
01:46
So how does me learning
about this particular
type of glomerulonephritis
help me keep a patient safe?
Well, I can educate the patient
or their parents or
family or caregivers
to let them know to be
on the lookout for this
we want them to know the
signs to watch for after strep
so they can get help
if the patient is having some
pretty significant signs.
02:11
So what things would
we teach a patient?
Well as we teach anybody
who's taken antibiotic
take the complete course of the
antibiotics just as prescribed.
02:20
Nobody likes taking medicine.
02:23
So people take an antibiotic
they start feeling better
and so they think man I'm not
even going to mess with that.
02:28
I feel fine.
02:29
Wrong not a good plan, Right?
So that helps us
develop resistance,
which we don't want
because resistance
makes superbugs like
MRSA and VRE and all
those other ones we have
and they might not completely
knock out that infection.
02:43
So educate all of your patients
no matter what the infection is
to make sure they take the
complete dose of antibiotics
Now personal hygiene,
you wouldn't think we need to explain
this to people but we really do
especially the ones
with skin lesions.
03:00
If they're putting on a topical
ointment would be better
for them to wear gloves
and then throw those gloves away
and wash their hands
that would be better than just
putting it on with their finger
and definitely wash
their hands after that.
03:14
So we want to remind them
that hygiene will help
not spread that infection
and we want them to know
the signs and symptoms
of glomerulonephritis.
03:22
All right?
Those are the big three
and knowing how does it
help me keep a patient safe.
03:28
It's all about educating,
take your medicines as prescribed.
03:31
Please be really careful
of personal hygiene
and you don't want the little
one around other children
until they've been on
antibiotics for a little while
and you want them to know
the signs and symptoms
of glomerulonephritis.
03:44
Now, this is my worst nightmare
when I see this kind of stuff
my brain just goes on overload.
03:50
I've got like what a big old
list of five medical terms.
03:55
This is just boring.
03:57
So let me show you some ways
that you can remember
this information?
It's a strategy called chunking.
04:03
Now it doesn't sound very
scientific but it's research-based.
04:07
We used to think that you
could remember seven items.
04:10
Yeah, now we know it's really
just about four at the max.
04:13
So what we need to do is
look for relationships
in these answers
so we can remember them
and what we want to
watch for as far as signs
of developing
glomerulonephritis.
04:24
Now by the way,
these are signs for
anybody whose kidney
is struggling, right?
Now glomerulus is real
important part of your kidneys.
04:32
So anyone whose
kidneys are struggling
are going to show you
some of these signs.
04:37
Ready?
All right,
let's make this list go away
and we'll start breaking
it down one by one.
04:43
So you would assess
your patient for signs
of glomerulonephritis,
which we know equals
decreased kidney function
and a lower GFR.
04:53
So think what do you know?
Let's start with normal.
04:56
What do healthy kidneys do?
All right,
we know they remove waste
and extra water and make
urine, cool!
and they filter the blood
so they remove waste and extra
water and they filter the blood.
05:09
So as I'm studying
and I'm learning and
I'm walking through this
I always know if I'm starting
with a disease that
affects an organ system,
First, I do a quick review.
05:20
What do healthy organs do?
So healthy kidneys remove waste
and extra water make urine
and they filter the blood.
05:29
You need to be
solid on that point
before we can look at
what the problems are
when it isn't functioning now.
05:35
Now I would recommend
you have our notes
which are pretty helpful,
but it's really
important that you
write this out or draw this out
in a way that makes sense to you
what your brain has to
do the mental gymnastics
that your brain
has to do to decide
what you're going to write down.
05:51
Don't just copy what we have
put it in your own words
that will help encode the
information in your brain
so you can remember it when your
taking a test and what
we really care about
when you're taking
care of patients.
06:04
All right,
so we know glomerulonephritis
is decreased kidney function.
06:08
We know what healthy kidneys do.
06:11
So we know if I have
glomerulonephritis.
06:13
These things aren't
working that well, right?
So what happens
if I can't get
rid of extra water
and I don't make
your in very well,
right and I don't
filter the blood.
06:24
Well, here's what happens
if I can't remove
the extra water.
06:28
I'm going to have a Edema.
06:29
That is extra fluid on board.
Right?
I have more fluid
than my body needs.
06:35
What does it look like?
Well, sometimes my legs
will get really swollen
or I'm going to be
if I put my finger
if I put my thumb
over a shin bone
and when I let my thumb
up I have that divot
that is pitting edema.
06:49
So why do I have edema?
I have extra water on board
because my kidneys
aren't functioning well
can't get rid of it.
06:56
Now hypertension.
06:57
Oh, why do we put
these two together?
Because extra fluid on board
means there's extra volume
in my intravascular space.
07:06
That's just a fancy word for
in my vessels right?
In my arteries in my veins.
07:11
I got extra fluid
because my kidneys
can't get rid of it.
07:14
Therefore my blood
pressure goes up.
07:17
So because I know it
can't remove extra water
I'm going to have
Edema and hypertension.
07:22
Because I can't make urine.
07:24
Hey, there's where those
fancy things come from.
07:27
Oliguria means can't
Olig means scant
"uria" means urine.
07:33
So if these are words
that are new to you,
make sure you write in your
notes Olig scant, uria urine.
07:39
Now Hematuria.
07:41
He met refers to blood
urea again as urine.
07:45
Proteinuria is
protein in your urine
and that's when they're
not making urine well,
there's not going to be very much of
it and it might look kind of weird
to have blood in it or protein
which you can't
necessarily see the protein
unless there's a whole lot of it
and then It gets kind of frothy,
but you may not
be able to see it.
08:03
Okay, we know glomerulonephritis is
a kidney that's not working well.
08:07
So we know the ways of
healthy kidney works,
we've looked at the
the ways they do that
remove waste extra
water make urine.
08:15
When they can't do that
they end up with
Edema hypertension.
08:19
We also have some weird-looking
urine and not very much of it.
08:23
Now it also filters the blood
a kidney that's taken a
hit kind of limping along.
08:29
It can't filter or
remove very efficiently.
08:31
So I'm going to end up with a
lot of extra stuff in my blood
that I don't necessarily want.
