00:00
So let's look at an
abdominal CAT scan,
remember we're looking
for acute cholecystitis.
00:05
So we want a shot right here.
00:08
When a patient goes
down for a CAT scan,
we don't do a head-to-toe.
00:12
We're just going to focus on the
area where we think the injury is.
00:17
So this takes about 10 to
30 minutes to complete.
00:20
So as you're preparing your
patient for an abdominal CT scan,
you want to let them
know what to expect.
00:27
Now this one is
also non invasive.
00:28
Look at what you see there
you got the big donut,
and then you see the table
that's slides outside of it.
00:34
The patient if they fit the
correct size for the CAT scan
will be slid into that round donut
hole so we can take the pictures.
00:42
Now this uses X-ray and computer
technology is pretty cool,
to give us images that are much
more detailed than an X-ray.
00:51
That's why if we couldn't tell
what it was and an ultrasound,
step up to abdominal CT scan.
00:57
Both are invasive, but you want to
guess which one costs a lot more.
01:01
Yeah, it's this one.
01:03
So we try to do as minimally
invasive testing as we can
and try to keep it as
cost efficient if we can
as long as it gives us
an accurate diagnosis.
01:13
Now we can also while we're in
there, take a look at the liver,
the spleen the colon the
pancreas or the kidneys,
all in that one
abdominal CAT scan.
01:23
Keep in mind this takes
only about 10 to 30 minutes
to get some pretty
amazing pictures.
01:29
Now if the CAT scan is
ordered with contrast dye,
Pause.
01:35
This is where you really
have to pay attention, okay,
because this could cause some real
challenges or risks for your patient.
01:42
So make sure you have
that starred and underline
if the cat scan is
ordered with contrast dye,
It's best for the patient not to eat or
drink for three hours before the exam.
01:53
Now we don't always
have that luxury,
but that's the optimum best
way to go about it if we can.
02:00
We need before you
send them down though,
to assess the patient's
renal function.
02:04
There are certain medications that
could literally take out the kidneys
if we give them CAT scan dye,
and they happen to be on a
medication called metformin.
02:15
So this dye and the metformin
interact in a really adverse way.
02:20
And so you have a risk of the
patient having severe kidney damage.
02:24
So you need to know for sure
how are the kidneys functioning?
So the patient can
get rid of that dye,
you need to know if they're on
any medication like metformin
because there is a kidney
killing interaction
that could happen if the patient
currently has metformin
in their system
and you also want to know if they
have a risk of allergy to the dye.
02:43
Now depends on which
type of dye that's used
some dyes are iodine based
so you would not want the patient
to have a shellfish allergy
and receive this dye.
02:52
So dye gives some really
cool pictures, right?
We can do it without
dye or with dye,
but as the nurse it's your job to
recognize what's going on with that test.
03:02
Make sure the right assessment
questions are asked.
03:05
How are the kidneys doing?
Are there any medications that
will interact with this dye?
And is there any risk that the
patient could be allergic to that dye?
That's our responsibility as
part of the healthcare team.
03:18
Now, there's other checks
and balances along the way
but know that our
responsibility is to our patient
and to keep them safe.
03:26
That's why we have to know what's
being ordered for the patient
so we can evaluate what
questions we need to ask.
