Okay, so let's talk about the
most important points
that you need to know as a nurse
in being part of the team that selects
the most effective antibiotic
for your patient.
So we had the narrow spectrum
and the broad spectrum.
Narrow-spectrum antibiotics treat a
smaller number of types of bacteria.
Broad-spectrum antibiotics treat a wider
range of types of bacteria,
but -- the sad news is
they promote microbial resistance.
So, your job is to make sure
that we can get the patient on the
most narrow spectrum
that's still effective to treat the bacteria,
in collaboration with your
We talked about a way to
that just lets you know, kind of, how
things are laid out in this course,
we use their mechanism of action.
We initially talked about 7 of them,
but we're really looking at
the 4 main ones as we go through
the rest of the course.
We talked about the difference between
prophylactic and empirical antibiotics.
Remember, prophylactic antibiotics is
you don't have an infection yet,
but we're going to put you in a situation
that puts you at a risk
to have an infection,
like surgery or a dental procedure.
So, we're going to give you an antibiotic
when you don't have an infection
because we want to prevent the chance or
minimize the risk of you developing one.
Now empiric therapy is -- yeah, sad news.
You have an infection, but we don't
know exactly what bugs
are causing it, so what we're going
to do is give you our best
clinical educated guess,
until we get those culture and
sensitivity reports back,
and we'll put you on a more narrow
spectrum antibiotic after then.
The effectiveness of the antibiotic
therapy is evaluated
by looking for clinical signs that
the infection is resolving,
so less redness, less pain, less
swelling, less fever,
and a normal white blood cell count.
Well, that wraps up everything you
need to know that you can start
to put into clinical practice
for learning how to make sure your patient
is on the most effective antibiotic.
