Now, that we're clear
that meningitis
were the location of the structures
that are inflamed
there inside your head.
00:07
Let's look at
what can cause meningitis.
00:10
Now, there's not just
one straightforward cause.
00:12
So stick with me, I'm going
to give you a list of things
in two separate categories.
00:17
Now, the first it could
be caused by viruses
are pretty familiar with that it
would be called viral meningitis.
00:24
It could be caused by bacteria,
which is also named
bacterial meningitis.
00:28
Now, the last two are kind
of weird in this category.
00:31
It could be a fungi,
or it could also be a parasite.
00:35
That just leaves me out
and gives me nightmares,
the thought of a parasite being
inside your head like that.
00:42
But all four of
these little fellas,
they fall into one category
called infectious meningitis.
00:48
Okay, so you've got that platform.
You've got that framework.
00:51
You know, there's two main
categories of causes of meningitis.
00:55
One is infectious, and could be
viruses, bacteria, fungi,
or parasites.
01:01
The other category
is noninfectious.
01:04
So, this one is a little weird,
a little trickier.
01:07
And something that's important
I want you to keep in mind
is remember that viruses are the
most common causes of meningitis.
01:13
Okay, pause.
So, write yourself a note
that viruses are the most
common cause of meningitis.
01:20
But bacteria is the most
contagious form of meningitis.
01:24
And that's really important
that you keep that straight.
01:27
Now, in our downloadable materials,
you can find a table
where the organisms
that actually cause meningitis
are more specifically classified
and listed for you.
01:35
Just in case you've got
some extra free time
on your hands to take a look at
that. But it's really interesting.
01:40
And particularly, if you get to care
for a patient who has meningitis,
you're going to want
to consult that chart.
01:46
So, make sure, you take a look
at it now, but don't memorize it.
01:50
But hang on to it for reference
when you're doing patient care.
01:53
This next section is really
important to me that you understand
because I want you
to be safe in practice.
01:59
Now, how meningitis
is spread is by droplets?
It's not the only diseases
spread by droplets.
02:04
But with meningitis,
think back to what you know
about droplet spreading.
02:09
How does that work?
That's when a patient coughs or
sneezes somebody who's contagious.
02:14
Those droplets go
into the atmosphere.
02:17
The other person inhales them
just with normal breathing,
and then you end up
with big problems.
02:24
So, before I even go on,
I want to stop right here,
another red slide to
catch your attention.
02:29
Because it's always important
that you wear the appropriate PPE.
02:34
Now, sometimes things change
or recommendations change.
02:38
You just have to look
at the research.
02:40
Your hospital will have a policy,
or stay up on what your
agencies recommend.
02:44
But it is so important
that you do not cut corners,
or try to get into a room quicker
without putting on your PPE.
02:52
your Personal Protective Equipment.
02:55
Okay, it was important enough
for me to remind you that
that I wanted to take time,
right here in this video
to remind you,
we need you strong and healthy.
03:05
If you're going to be
taking care of patients and
enjoying life with your family.
03:09
Sometimes you've learned
things in nursing school,
but you kind of memorize them
rather than understand them.
03:14
This is one of those examples.
I want you to think through.
03:17
How does an inhaled microorganism
end up being meningitis?
Well, once it's inhaled,
it travels through the body
and it sometimes ends up
in the meninges.
03:28
Now, remember,
we have three of those, right?
You see if you can name them.
Don't look at your notes.
03:34
Close your eyes and see
if you can try to recall that.
03:36
That is an excellent study strategy
from the how you PAD your brain.
03:42
Can you remember
those three layers?
So, I've got the
microorganisms in there.
03:45
They've traveled in the brain.
They're in the meninges.
03:48
Now look what happens
to the meninges.
03:51
There you go.
You've got this bright red
The artist has created for you
to help you know that that's
what generates the inflammation.
03:58
The body is responding
to those microorganisms.
04:02
This is when the patient
will present with meningitis,
inflammation of the meninges.
