Hi, I'm Cathy with Level Up RN. In this video, we are going to talk about meningitis,
and at the end of the video, I'm going to give you guys a little quiz to test your knowledge
of some of the key facts I'll be covering in this video. So definitely stay tuned for that.
If you have our Level Up RN medical-surgical nursing flashcards definitely pay close attention
to the bold red text on these meningitis cards because there's a lot of key concepts and facts
that you definitely have to know about this disorder. Meningitis is the inflammation of the
meninges, which are the membranes that surround and protect the brain and the spinal cord.
So the pathophysiology behind this disorder is that you have an infectious organism,
which could be a bacteria or a virus that enters the central nervous system and the meninges,
either through the bloodstream or directly through trauma. So viral meningitis usually resolves
without treatment. Bacterial meningitis is usually more severe and does require antibiotics
and can be life threatening. In terms of the risk factors associated with meningitis, this includes
crowded conditions such as dorms or prisons, for example, immunosuppression, and travel exposure.
In terms of prevention, infants are given the Hib and the PCV vaccines, which helps to protect them
from meningitis. Teenagers are given a meningitis vaccine, particularly, before they go to college
and live in a dorm, which is a crowded living condition. So I just sent my son up to college,
and we definitely made sure that he had his meningitis A and his meningitis B
vaccines prior to moving up there. Signs and symptoms of meningitis include a
fever, headache, nausea and vomiting, as well as nuchal rigidity, which means
neck stiffness, and then the patient may also have photophobia, which is sensitivity to the light.
And then they will also exhibit a positive Brudzinski sign as well as a positive Kernig
sign. So I'm going to explain these two signs here. So a positive Brudzinski sign,
if you want to test for that sign, you would have the patient kind of lay down flat on their back,
and you would place one hand on their chest and the other hand behind their head, and you
attempt to pull up their head like this. And that will cause them pain such that they flex in their
knees and hips. So the way I remember the sign, if you look at the word Brudzinski, it starts with
Bru. So if you try to pull up your patients' head, they'll be like, "Bru, that hurts." So
that's how I remember that sign. And then with the Kernig sign, Kernig starts with K
and the word knee starts with K. So with this test, you would have the patient
lay flat, you would have them bend their knee and you would attempt to straighten out their
leg. And I'm a little stiff, but if that really hurts and they're unable to do that,
then that would be a positive Kernig sign. So hopefully that little demonstration helped you.
Other signs and symptoms can include altered mental status, tachycardia, and seizures.
In terms of diagnosis, we are going to obtain a cerebral spinal fluid sample through a lumbar
puncture. We're going to analyze the CSF and depending on whether the patient has
bacterial meningitis or viral meningitis, we will have different findings with the CSF. So if the
patient has bacterial meningitis, that CSF will be cloudy. The glucose content will be decreased,
the protein will be increased, and the white blood cell content will be increased. And then we
will have a positive Gram stain. If the patient has viral meningitis, that CSF will be clear,
and the glucose level will typically be normal. We may see a slight increase in protein
and white blood cells, and we will have a negative Gram stain. So in terms of treatment, we would get
antibiotics for bacterial meningitis. We can give analgesics for either type to help with the pain,
and we can give anticonvulsants, if seizures are a concern for the patient.
Nursing care associated with meningitis includes the implementation of droplet precautions
for any patient with suspected or confirmed bacterial meningitis. So they will need to stay
on those droplet precautions for the first 24 hours with antibiotic therapy. So our little
cool chicken hint for remembering this, if you happen to know the song, It's Raining Men, which
is by the Weather Girls, and it came out in the 80s, and I have to admit that I was around when
this song was big. If you don't know it, you ought to Google it. But it goes, "It's Raining Men."
And so that will help you remember that with meningitis, you will have droplet precautions.
So like raindrops. So It's Raining Men. Meningitis requires droplet precautions. The other thing you
want to do is implement seizure precautions. So that means patting the side rails of the bed,
making sure you have oxygen equipment available. You want to monitor your patient's neurological
status. You want to provide a quiet room with dim lights because of that photophobia, and then you
want to minimize your patient's intracranial pressure. So we want to maintain the head of
the bed at 30 degrees. We're going to want to keep their head midline and minimize any suctioning.
All right, it's quiz time. And then after this quiz, I'm pretty sure there's going to
be a blooper. So you'll want to stay tuned for that. With our quiz, we have three questions.
First question, what is the difference in CSF appearance between bacterial and viral meningitis?
The answer is the CSF will be cloudy with bacterial meningitis and clear with
viral meningitis. Question number two A patient with meningitis may have a positive
Kernig and positive Brudzinski sign. True or false? The answer is true. And
those were the two signs that I so eloquently performed for you guys. Question number three,
What type of precautions should the patient be put on for suspected bacterial meningitis?
The answer is droplet precautions. Okay. That's it for this video. If you've enjoyed it,
be sure to like this video. Leave me a comment. Take care and good luck with study.
With antibiotic therapy, and then they can be that the
the the the do-da-do. [laughter] Sorry. Let me try again.
