Welcome to the series,
finger-stick blood glucose level.
00:07
This is also commonly known as a blood
sugar, you may hear that name often.
00:12
So we're typically going to get this
important piece of diagnostic information
in several different patient conditions
but especially our diabetic patients.
00:22
So let us look at some important
points to keep in mind.
00:26
Now, the principles of obtaining the
actual level is about the same throughout.
00:31
But just know there are several
different types of glucose monitors
and there's a lot of variations to this.
00:38
So you want to become really familiar
with the agency equipment that you have.
00:42
Just know also that the
equipment used in a hospital
versus the stuff that maybe your patient uses
at home is going to be quite a bit different,
and therefore the capabilities and the
limitations of your monitor will vary.
00:58
Just keep in mind when we're
talking about obtaining this,
now the client's order is going to vary quite a bit.
01:05
It's going to be relevant to their condition.
01:07
Here is a great example of that.
01:09
If we're talking about a
diabetic patient, for example,
we may obtain this level maybe AC and HS,
otherwise know as before meals and at bedtime.
01:20
You may also see the order for
blood glucose level every 6 hours.
01:24
This could be potentially because your patient is
on ongoing to feeding on nutritional supplements.
01:31
Now, some higher level care like the intensive
care unit, we may take this level a lot more often.
01:38
So when we're talking about a blood glucose level,
it's important to know really critical ranges.
01:45
What I'm talking about here is your facility's
protocol for what we say is hypo, meaning low
and hyper, meaning high glycemia.
01:54
So a high and low blood sugar.
01:56
So hypoglycemia, most facilities are
going to say that this is the case
when your patient's blood glucose
reaches less than 70 mg/dL.
02:08
We also define hyperglycemia, most
commonly, greater than 140 mg/dL.
02:15
Now let's note that the American Diabetes Association
is going to define hypoglycemia as less than 54 mg/dL.
02:26
They're also going to define severe hypoglycemia
of less than 54 mg/dL with symptoms.
02:37
Now let's talk about some signs and
symptoms of both of those conditions.
02:41
So when we're talking about hyperglycemia,
meaning an elevated blood glucose,
defined as greater than 140 mg/dL, here are
some signs and symptoms that you may see:
such as fatigue, maybe blurred vision,
maybe excessive thirst or fruity breath.
03:00
So let's just talk about the fruity breath, that's
typically meaning that we have blood glucose
in the extremely elevated ranges.
03:08
And this could mean the patient's blood glucose is
so high, they could be close to going into a coma.
03:15
This is an emergency.
03:17
Now, some clients may not
display symptoms of hyperglycemia
until the blood glucose is extremely high.
03:24
Or the patient could also have nausea
and vomiting and increased urination.
03:29
So just know with typical hyperglycemia, if this
is a chronic issue for our diabetic patients.
03:36
Now, the patient could be running
at maybe 200's (mg/dL), for example
for a long time and not have many
of this symptoms or even any at all.
03:45
So this is why important glucose monitoring is a
great education for your patients who have diabetes.
03:53
Now let's look at the flip side of that
otherwise known as hypoglycemia.
03:58
Now, depending on your agency's protocol,
it could be defined as less than 70 (mg/dL)
or here, as less than 54 mg/dL.
04:08
Now here's the difference.
04:10
When a patient has hypoglycemia, they are
much more likely to show symptoms here.
04:16
Such as anxiety, just not feeling right,
a lot of confusion, some tingling.
04:22
The patient may start having diaphoresis
or sweating and getting clammy,
tachycardia or fast heart rate,
hunger or even the shakes or tremors.
04:31
So when you're talking about hypoglycemia, this
is typically much scarier for you as a nurse
and has to be treated quickly.
