MLSP: LESSON 2 Venipuncture equipments Flashcards
act of entering a vein to obtain a
blood sample
Venipuncture
3 methods of obtaining blood samples
o Venipuncture
o Arterial puncture
o Capillary puncture

Capillary puncture
3 ways of doing venipuncture
o Syringe Method
o Evacuated Tube System method
o Butterfly Method
Materials used to collect sample
Phlebotomy Collection Tray
Contains syringe, tubes, cotton, gauze pads, and needle container
Phlebotomy Collection Tray
patient must be in upright and comfortable position
Phlebotomy chair
(true or false)
The table contains the materials needed for
blood extraction
true
what ETS means?
Evacuated Tube System
to cover the needle to prevent needle prick injury
Safety shield
TRUE OR FALSE
multisample needles with color-codes caps, both traditional and BD eclipse safety needle with the safety shield attached, Greiner Bio-one black 22 gauge, green 21 gauge.
True
(TRUE OR FALSE)
Multisample needle color indicates the size of the needle
true
needles used in ETS
multisample needles
needles used in syringe method
hypodermic needles
needles used for butterfly method
winged blood collection needles
(true or false)
sterile, disposable, and are used only once.
true
(true or false)
Needle size varies by both length and gauge
(diameter).
true
For routine venipuncture, __inch and __-inch
lengths are used.
1 and 1.5
part of the needle that will be inserted
first in the vein
point
opening of the needle (should be
up)
bevel
indicator that you hit the vein
hub
part of the needle
that is inserted to the rubber of the blood tube
Stopper-puncturing end
refers to the diameter of the
needle bore (hole of the needle)
Needle gauge
needles used to collect units of blood for
transfusion
large (16 gauge)
needles used for very small veins.
smaller (23 gauge)
(true or false)
The smaller the gauge number the
bigger the bore diameter of the needle.
true
have the stopper puncturing needle covered by a rubber sheath that is pushed back when a tube is attached and returns to full needle coverage when the tube is removed.
Multisample needles
made of rigid plastic and may be designed to act as a safety shield for the used needle.
- Sometimes called as “adapters”
needle holders
Rigid, puncture resistant, leak proof disposable
“sharps” containers labeled BIOHAZARD that are easily sealed and locked when full.
Needle disposal systems
Evacuated tubes or Vacutainers
collection tubes
(true or false)
Different colors of stoppers indicate the type of
tube (to know if there is anticoagulant present in the tube)
true
no anticoagulant; tube is meant to prepare serum specimen in clinical chemistry analysis
Red
EDTA (Ethylenediamin tetra-acetic acid);
Violet/lavander
heparin
green
sodium citrate
blue
(true or false)
Phlebotomist is able to control the
suction pressure on the vein by slowly
withdrawing the syringe plunger
true
(true or false)
blood will appear in the hub of the
needle when the vein has been
successfully entered.
true
(true or false)
Blood drawn in a syringe is immediately
transferred to appropriate evacuated tubes to
prevent the formation of clots.
true
(true or false)
It is not acceptable to puncture the rubber
stopper with the syringe needle and allow the
blood to be drawn into the tube.
true
- provides a safe means for blood transfer without using the syringe needle or removing the tube stopper
- It is an evacuated tube holder with a rubber
sheathed needle inside. - After blood collection, the syringe tip is inserted into the hub of the device and evacuated tubes are filled by pushing them onto the rubber sheathed needle in the holder as in an evacuated tube system
blood transfer device
used for the infusion of IV fluids and for
performing venipuncture from very small or very fragile veins often seen in children and in the geriatric population.
Butterflies
usually 21 or 23 gauge with lengths of 1/2 to 3/4 inch.
Butterflies
used during venipuncture to make it easier to
locate patients’ veins.
tourniquets
2 inches above the puncture site (anticritical
fosa) basillic vein, phallic, vein, and median vein
tourniquets
primary antiseptic used
for cleansing the skin in routine phlebotomy
70% isopropyl alcohol
used for applying pressure
to the puncture site after the needle has been
removed.
2x2 inch gauze pads
(true or false)
cotton ball fibers can stick to the
venipuncture site and may cause
bleeding to begin again when the cotton
is removed.
true
