00:01
So let's start off with
our neurological system.
00:04
So this is where
we're starting at the head,
one of the first things
that we're going to start doing.
00:09
And the neuro system tells you
a lot about your patient.
00:12
So many times, that how we
assess the neurological system,
now, it's going to vary depending
on the type of patient you have.
00:19
So for example,
if I have a stroke patient,
a head injury patient,
I may deep dive
a little bit more into this system,
versus if my patient is
awake, alert and oriented,
and maybe they had
a bowel obstruction, for example.
00:34
So we talked about
the neurological system.
00:36
Mostly, the assessment that
we're going to perform is, again,
that level of consciousness.
00:42
I mean, I will tell you,
the level of consciousness
says so much about the patient.
00:48
This is one of the first indicators
that if I walk into a room
during my bedside shift report,
my patient was awake
and alert and talking to me,
then I leave,
I come back 30 minutes later,
and the patient,
we can't hardly arouse.
01:02
That's a big indicator
for a rapid response
or emergency intervention.
01:07
So a level of consciousness
is really big indicator
for the neurological system.
01:12
Then many times
a general assessment,
we'll look at pupils to see
if they're light accommodating,
looking at the size.
01:19
If the patient has feeling, and
if the patient has any paralysis,
meaning they can't move
one of their limbs.
01:26
Now again, depending on
what the patient's diagnosis is,
what they came in for,
we may move into more
of a focus assessment
such as looking at reflexes,
including that sensation
and coordination as well.
01:41
Cranial nerves, and we'll do more
of a sensory evaluation.
01:45
So just note
there's an expansive
neurological deep
detailed assessment
if indicated for your patient.
01:53
Now, let's talk about some of the
main ones of the neurological system
that we would cover
as a nurse.
01:58
So again, starting with
that level of consciousness.
02:01
So we use something called
the Glasgow Coma Scale,
or you'll hear the term GCS a lot.
02:08
Now, this is a really common
method and evidence based method
to assess and document the
neurological status of our patient.
02:16
And again,
this is very widely used.
02:19
So this is actually you can start
assessing this really easily.
02:23
Like when we enter
the patient's room,
we introduced ourselves.
02:26
We asked them even,
"Hi, can you tell me your
name, and date of birth?
Can you tell me where
you're at right now?
And what brought you
into the hospital?
Just asking those
orientation questions
and assessing the patient response,
you actually cover,
believe it or not,
a lot of the Glasgow Coma Scale.
02:43
and we'll talk about
each one of these.
02:45
So to cover
with the Glasgow Coma,
know, it covers three main areas:
eye opening, verbal response,
and motor response.
02:56
So now let's dig into this GCS
a little bit more
on how we use it
to assess our patient.
03:01
So first, we start with the eyes
and the eye opening.
03:05
So just know when you're talking
about this specific scale,
you're going to rate
each patient response,
and then you're going to
add all these numbers up,
and you'll get a total.
03:16
Now, here's the key thing to know.
03:17
And this is why the GCS is so nice,
that if it's a high functioning
patient, you should have a 15,
or a high level or a high number.
03:26
Such as me setting here
talking to you today.
03:29
You could say that I'm a 15.
03:32
So I've got good eye, motor,
and verbal responses right now.
03:36
So I should be higher
on the GCS at a 15.
03:40
However,
if a patient's very ill,
and they aren't able
to open their eyes,
or they have mobility,
motor issues,
they may be lower at like an 8.
03:50
Now, if a patient's at like
an 8 or lower,
this could mean the patient
could be potentially comatose,
or really not responsive.
03:57
So again, GCS is great, because
at a quick glance at a number,
you have a good idea of the
neurological status of your patient.
04:05
So let's start talking about
the eyes in particular.
04:08
So if you look here on the GCS,
and we talk about the eye opening,
we're gonna start with
the big numbers here
on this image to orient you.
04:16
So number 4,
if we write them in a 4,
it's just like you see here
that I'm opening my eyes
spontaneously to noise.
04:23
I don't have any issues
doing this just naturally.
04:26
Now, 3, if we have
to score a patient at a three,
it's they're only open them
to verbal command.
04:32
So this can mean you walk
into the patient's room,
and you have to call
a patient's name
for them to open their eyes,
for example.
04:41
Now 2, when we're talking about
eye opening,
this means the patient could be
in bed, you walk in,
they don't hear,
even if you make a noise,
opening the door.
04:51
You start calling their name,
they don't respond,
but maybe you have
to put a painful stimuli
or apply a painful stimulus.
04:59
Then the patient
will open their eyes.
05:01
Then we rate them at
a lesser score of two.
05:05
And then, of course,
at the very lowest
is the patient doesn't
open their eyes at all
and their score to one.
05:11
So that's how we
evaluate eye opening.
05:15
So now let's move on
to verbal response,
which is just how your patient
speaks to you.
05:20
So we're going to start
with this higher number
to orient you on that slide
over here up to five,
which is oriented.
05:26
Like, the patient knew
their name and date of birth,
they're answering appropriately,
they knew what month,
who the president is?
All of those appropriate responses
to orientation questions.
05:37
Now, 4 is a little bit different.
So they're a little bit confused.
05:40
So they can talk to you,
but maybe they think
their birthday is in December,
when really it's in March.
05:47
Maybe they think they're in Hawaii,
and really, they're in Oklahoma.
05:52
So these are things to where
we would score them into 4
that the patient's confused.
05:58
Now, here's where it gets
a little bit different
and we've got
to discern as the nurse.
06:02
Now 3, is inappropriate words.
06:05
So sometimes, we'll say
this kind of like a word salad
or something like that.
06:09
And here's a great example of that.
06:12
Let's say you have a patient
and you've got a bedside table,
and there's a pencil laying
on the bedside table.
06:19
Let's say you talk
to your patients say,
"Okay, Mr. Jones, this is an
object laying on the table.
06:25
Can you tell me what this is?"
Now most everybody can tell
you, it's a pencil, right?
But what if he says,
baseball instead of pencil?
Well, this is an appropriate.
06:35
Now, this could be
because of a stroke,
a specific area of the brain
that's been damaged.
06:40
Now, moving down
into a lesser score is 2,
which is incomprehensible sounds.
06:46
So this is going to be more like
noises, or grunts, or maybe mumbles.
06:52
Now, you're not going to get
really formed words,
or anything that you can
technically comprehend here.
06:59
And one, of course,
is a no verbal response.
07:02
So this could mean
the patients ventilated.
07:06
It could mean that they're sedated,
or they're in a coma.
07:10
Now finally, let's look at
the last part of this scale.
07:14
Now, here we're talking about
motor response.
07:17
Now, this is something
that we ask the patient
to actively engage
with us physically.
07:23
So if you start here
on the slide at the bottom,
and we're looking at this
big number of obey commands.
07:28
This is going to look
at something like
okay, so means that I need
you to raise your left arm.
07:34
So I would raise my arm.
07:35
So per the verbal command,
I can obey
and I can respond quickly,
and I would score about a 6.
07:42
Now, when we're talking about
moving down the scale at a 5,
this is purposeful movement
to painful stimuli,
such as, I applied pain, and
the patient appropriately moves.
07:53
Now, 4 is going to be
a little bit different,
where maybe the patient's not
purposely moving every time
when we apply painful stimuli.
08:02
You have to apply
the painful stimulus
to see if they withdraw from you.
08:07
This is a little bit less of a
response and coordinated at a 4.
08:12
Now, moving down this, if you see
number 3, and number 2,
this is not a positive sign.
08:18
This is usually meaning a
bad outcome in your patient.
08:21
So if you see a patient
with their flexion to pain,
meaning they go
what we called decorticate,
meaning inward and flexing
inward towards their core,
that is an ominous and a sign
with your patient neurologically,
and needs to be reported.
08:36
Now, the same thing here with 2,
we call it decerebrate
or extension to pain
where the patient
may be extends out.
08:43
This is also a negative
sign in your patient
and also needs to be reported.
08:47
And 1, of course,
is no motor response.
08:51
So we just talked a lot about the
Glasgow Coma Scale or the GCS
and its components.
08:56
Now seems pretty complex,
but it's actually quite easy
to apply it to a patient case.
09:02
So let's take a look and apply it
to a patient scenario here.
09:06
So this is Mr. Hering,
and he's a 49-year-old client.
09:10
Now he experienced
a loss of consciousness
and he was found down
this morning by a co-worker.
09:16
Now upon our assessment,
we see that Mr. Herings, lethargic.
09:20
Now, his eyes are closed
most of the time,
but actually,
when we asked him,
he will open his eyes
to verbal commands.
09:27
Now, when we ask the orientation
questions with Mr. Hering,
he's not oriented to time or place,
but when we ask and
assess his motor response,
he can indeed follow
simple commands
and move his extremities or
grip the hands of the nurse.
09:43
So now let's take a look at the
graph next to him in the coma scale
and see how he scores.
09:48
So, if you recall here
in the middle,
now Mr. Hering was lethargic,
eyes were closed most of the time,
but upon verbal command,
he opens his eyes.
09:58
So if you take a look
here on the graphic
he's going to score a 3
that he opens to verbal command.
10:04
Now when we're talking about
orientation and verbal response,
when we ask those very,
very typical orientation questions,
he actually wasn't
oriented to time or place.
10:16
So we actually deam this confusion
and here on the Glasgow Coma Scales,
he would be scored
a four at confused.
10:24
Now, assessing the motor response,
if you are called
now he can follow
simple commands
like Mr. Hering, raise your arm
or grip the hands of the nurse.
10:33
Now, because he was easily and
appropriately able to obey commands,
we score him here at a 6.
10:40
So if we sum up all those numbers of
a 3 to verbal, of 3 to eye opening,
a 4 to verbal,
and a 6 to motor,
that scores is 13
on the Glasgow Coma Scale.
10:53
So know on the Glasgow Coma Scale,
the highest number you have is a 15.
10:59
So that means he has
a great GCS score.
11:02
Now, if Mr. Hering was closer
down to an 8 or lower,
this could mean that he has
severely impaired eye opening
or verbal or motor response issues.
