Capillary Puncture | Finger stick for Glucose Testing | Medical Assistant
Summary
TLDRThe video script demonstrates a step-by-step process for performing a finger stick blood glucose test. It covers the preparation of supplies, including glucose strips, a glucometer, alcohol, gauze, band-aid, and a lancet. The narrator explains the importance of choosing the middle or ring finger, avoiding the thumb, index, and pinky. The process involves cleaning the finger with alcohol, setting up the glucometer, and using the lancet to prick the side of the chosen finger. The first drop of blood is wiped away, and the blood sample is applied to the glucometer strip for a reading. The video concludes with the application of a band-aid after the test, ensuring the viewer is informed on how to conduct a finger stick blood glucose test correctly.
Takeaways
- 🩸 The procedure described is a finger stick for a glucose check.

Q & A
What is the purpose of the finger stick procedure described in the script?
-The purpose of the finger stick procedure is to perform a glucose check, which involves testing a person's blood sugar level using a glucometer and glucose test strips.
Which fingers are recommended for a finger stick according to the script?
-The script recommends using the middle finger or the ring finger, which are the third or fourth fingers, for the finger stick procedure.
Why are the pinky, index, and thumb not used for the finger stick?
-The pinky, index, and thumb are not used for the finger stick because they are not the preferred fingers for this procedure, likely due to their smaller size and different sensitivity or usage in daily activities.
What is the significance of cleaning the finger with alcohol before the finger stick?
-Cleaning the finger with alcohol is important to disinfect the area and prevent infection, and it also helps to ensure an accurate reading by removing any contaminants that could interfere with the test.
Why is it advised to wipe away the first drop of blood after the finger stick?
-The first drop of blood should be wiped away because it may contain alcohol residue or other contaminants from the cleaning process, which could affect the accuracy of the glucose reading.
What is the role of the lancet in the finger stick procedure?
-The lancet is a small needle used to puncture the skin and draw a small drop of blood for the glucose test. It is essential for obtaining the blood sample needed for the glucometer to measure blood sugar levels.
Why should the glucose test strip not be inserted into the glucometer until just before the finger stick?
-Inserting the glucose test strip into the glucometer just before the finger stick ensures that the machine is ready to receive the blood sample immediately, preventing the device from going into hibernation or sleep mode due to inactivity.
How does the glucometer indicate that it is ready for a blood sample?
-The glucometer indicates it is ready for a blood sample by displaying a drop of blood symbol or a similar visual cue, signaling that the device is activated and prepared to measure the glucose level.
What is the significance of applying pressure with gauze after the finger stick?
-Applying pressure with gauze after the finger stick helps to stop the bleeding and ensures that the blood sample is collected without excessive blood loss, which could affect the accuracy of the test.
What is the normal range for blood glucose levels, and how does the script indicate the result of 98 is good?
-A normal blood glucose level for a non-diabetic person is typically between 70 to 99 mg/dL before meals and below 140 mg/dL after meals. The script indicates that a result of 98 is good because it falls within this normal range.
Why is it important to avoid pressing on the top of the finger during the finger stick?
-Pressing on the top of the finger during the finger stick should be avoided because it can cause unnecessary pain and may affect the blood flow, leading to inaccurate blood glucose readings.
Outlines
🩸 Glucose Check Procedure
The video script outlines a step-by-step process for conducting a finger stick blood glucose check. The narrator explains the necessary supplies, including glucose strips, a glucometer, alcohol, gauze, band-aids, and lancets. The preferred fingers for the test are the middle or ring finger, avoiding the thumb, index, and pinky. The process involves cleaning the finger with alcohol, setting up the glucometer, and waiting for it to be ready for a blood sample. The narrator emphasizes the importance of not pricking the finger too early and the correct technique for using the lancet, which involves pressing it to the side of the finger and not the top. After pricking, the first drop of blood is wiped away, and the blood is applied to the glucose strip for testing. The video concludes with the blood glucose result being read and a band-aid being applied to the finger.

alrighty So today we're going to do a
finger stick we'll be doing a glucose
check okay so we got our supplies here
we got our glucose strips our glucometer
alcohol bag gauze band-aid and
um Lancet this is the little needle
small needle that we're going to use to
do her finger stickers so of course we
know that we're going to use either the
middle finger or the ring finger in
other words we're going to use the third
or fourth finger okay we want to avoid
um the pinky the index and the thumb
okay so what I'm going to do is I'm
going to go ahead and clean her first
and while her alcohol while the alcohol
is drying I'm going to set everything
else up
so we're gonna clean her
here
wipe it from the inside out while that's
drying did you want it through that
finger was it yeah okay I'm sorry
sorry about that
yeah most people go for the middle
finger I usually go for the middle
finger too when I have to get a finger
stick okay so and one thing I want to
mention we're not on top of her finger
we're on the sides okay
all right so I'm gonna clean that let
that dry while that's drying I'm gonna
go ahead and open the Band-Aid
foreign
stuff over there to the side open up my
Band-Aid now with these strips and the
glucometer to turn it on all you have to
do is enter the strip and you don't want
to enter the strip until you're about to
stick because if you enter it too soon
it's gonna it's gonna um the machine is
going to start hibernating or going to
sleep so you only want to enter the
strip
once you're about to stick and the
Machine will let you know when it's
ready for the patient's drop of blood
okay
all right so we had to get a new
glucometer and new strips because that
machine was giving us an error message
but same thing we're going to answer the
stripping and that's what's going to
turn it on so we don't press a button or
anything like that we just enter the
strip
okay
and it's going to turn on and it'll let
us know when it's ready for the blood
you will see a drop of blood there
that's how we know this is ready for the
blood okay so using what I do I grab a
piece of gauze okay because we do have
to wipe away that first drop of blood on
the patient's finger it's ready for the
drop of blood and this is we're going
where we're going to place the patient's
blood once we stick her finger so we're
going to take
the tip off the Lancet now this Lancet
will have to press on the patient's
finger hit the button some lenses you
just press it down on the patient's
finger and a needle Will Spring out but
in this case we do have to hit the
button so what I'm doing here I'm just
kind of milking her finger just a little
and notice I'm here on the side I'm not
up I'm not on the top of her finger I'm
right here on the lateral side right
there on the lateral part of her finger
alrighty so I'm gonna just milk it just
a little
and then I'm just going to stick
okay
and
we gotta wipe away the first drop of
blood right so I'm gonna wipe that away
and then with this machine all you have
to do is allow the blood to just
there we go and it'll read it'll take a
few seconds just to read in the meantime
we're going to press there with the
gauze and have the patient apply
pressure
and her glucose is 98 is that good
that's good all right and so now we've
done her finger stick so now what I'm
gonna do I'm going to just remove the
gauze there make sure it's not bleeding
anymore remove the gauze and then I'll
put a Band-Aid on
all right
