Hi. I'm Meris and in this video, we are going to be talking about the types of immunity and
the types of illnesses. I'm going to be following along with our Fundamentals of Nursing Flashcards.
These are available on our website, levelupRN.com. If you already have a set, you can follow along
with me. I'm starting on card number 35. Okay, so first up let's talk about the
different types of immunity, and on the card here you'll see that we have four different types.
We have active natural, active artificial, passive natural, and passive artificial.
Before we even get started talking about the types, I want to help
clear up what some of the terms mean. So when you hear active, I want you to think
fighting. Your body is actively fighting either the pathogen itself
or some component of the pathogen. When you hear passive, I want you to think
my immune system is not actually doing anything to fight off the pathogen. Instead, my immune system
is passively receiving the gift of antibodies. Now when it comes to whether it is natural or
artificial, natural means it's happening naturally through normal processes,
and then artificial means it's happening through science and medicine, okay?
So let's just use those four terms, and let's put them together. So when we talk about active
natural immunity, this means my body is actively fighting something off that it
naturally encountered, so this means I was exposed to a disease. For instance, I had chickenpox,
varicella when I was a child. So I was exposed to the disease. My immune system fought it off,
and now I have antibodies that it created by actively fighting off
something it encountered in the wild. Right? Now active artificial, this is going to be
vaccination. So when I got my COVID vaccine, my body was given the instructions to make a portion
of the pathogen, so not the whole pathogen. I was never actually exposed to the virus, but my
body actively fought the little component of the pathogen because your immune system doesn't know
the difference. So I have antibodies now that my body actively created by itself from fighting off
an artificial introduction, okay, so vaccination. Passive natural. So passive means I'm getting
those antibodies, and natural means it's happening naturally.
So this is going to be such passing antibodies through breastmilk.
So when the mom is breastfeeding a baby or even when baby is in the uterus,
babies receiving antibodies through the placenta. So that is going to be passive natural immunity.
Passive artificial is going to be when you receive IV immune globulin.
So some people who have certain types of autoimmune conditions go and get
infusions of different types of antibodies. Or for instance, some COVID patients were given
immune globulins of patients who had been exposed and fought and overcame COVID.
So that is going to be passive artificial. It's not happening
naturally. We're giving it to them in an IV. Important things to know - we do have a
key point here - the passive protection is immediate. You immediately have the antibodies,
but it doesn't last very long. Whereas the active, where we're actually fighting,
using our immune system, that is going to take several weeks to develop, but it is long-lasting.
So that is going over all of the different types of immunities. And I know they can be confusing,
but pay attention because we did bold and red the important words on this card.
Okay, so moving on to card number 36, we are talking about different
types of illnesses and risk factors. So first up is acute versus chronic
illness. An acute illness is one that appears suddenly. It usually has very severe symptoms.
The good news is that usually this can be identified and treated,
and the patient can go back to normal. So an example would be appendicitis.
Appendicitis, all of a sudden, I have abdominal pain, high fever. I go to the hospital.
They take out my appendix. I feel much better. Now, chronic illnesses, on the other hand,
have a slower onset, so it may happen gradually over time. And they may not respond to treatment.
Another important thing to know is that the chronic illnesses persist for at least one year,
if not longer. So for instance, I have an autoimmune condition. It is chronic. It
will never go away. So it's only going to respond to symptomatic treatment.
It took a long time for me to notice the symptoms to develop it and I have had it
for 15 years at this point. So that is the difference
between acute and chronic illnesses. Now when we talk about risk factors, we
talk about them in terms of modifiability. Is it something I can change, modify, or is it something
that no matter how hard I work, I can't change it? So modifiable would be things like my diet,
my lifestyle. Maybe certain medications I take, that might be a risk factor for
developing a certain other condition. Those things are all modifiable.
Non-modifiable things have to do with things I can't change, so things like my race or ethnicity,
things like my age and my family history. No matter what, those things are just part of me.
I can't change them. So that's the difference
between modifiable and non-modifiable. And nursing education for your patient
is going to focus on those modifiable lifestyle factors if we can try to
help them make changes in their lifestyle. The non-modifiable will help us know what our
patients are at risk for no matter what. Okay, so I hope that was helpful.
A review there for you of the different types of immunity and illnesses. If it was,
please give us a like. If you have something to add in the comments or a really great way
that you remember something, I very much want to hear it. So please leave us a comment below.
In the next video, I'm going to be talking about so much. We're going to be talking about fires,
equipment malfunctions, chemical exposure, tornados, and bomb threats. And you're not
going to want to miss this. This is very important information.
