filling tubes in the wrong order can result in
CONTAMINATION OF A SPECIMEN DUE TO ADDITIVE CARRYOVER
standard needle gauge for venipuncture
21g
coagulation dept runs these tests
PT / APTT / PTT
time needed for blood clotting in a tube containing no additive
30 - 60 mins
veins are anchored in order to
prevent the vein from rolling
royal blue top tubes are used to collect
toxicology and traced metal specimens
21g - 22g needles are used for
routine venipuncture
the proper order of vein selection
MEDIAN CUBITAL / CEPHALIC / BASILIC
, reasons to allow alcohol to dry completely before needle insertion
puncture will sting less, hemolysis is less likely to occur, evaporation process helps
destroy microbes
improper cleaning of venipuncture site can cause
INFECTION
second choice vein, more visible on obesse patients
CEPHALIC VEIN
tourniquets should never
tied over open sores (causes infection) / tied too tightly (cuases petechiae) / left on
longer than one minute (causes hemoconcentration)
to properl anchor a vein
pull the skin taut with your thumb, below the tube holder
butterfly and syringe needles may be used
on small frail veins such as those in children and geriatric patients
types of needles used for phlebotomy
hypodermic needle / multisample needle / winged infusion (butterfly)
yellow top tubes are used to collect
Blood culture specimens
during venipuncture the needle is inserted at
a 15 - 30 degree angle with the bevel up
lavender top tubes are used to collect
CBC specimens
when identifying a patient in the hospital seeting always
check the patients ID band / ask the nurse the patients name / ask the patient to state
his or her name
after venipuncture pressure should be applied
for at least 5 mins prior to bandaging
phlebotomist should avoid the basilic vein because
it lies near a major nerve and near the brachial artery and is more painful when
punctured
glucose tesst are collected in
grey top tubes
types of anticoagulants include
sodium citrate, EDTA, sodium heparin, lithium heparin and ammonium heparin
thixotropic gel found in light green tubes is a
coagulant
the easiest veins to anchor
median cubital veins
tubes containing anticoagulants
prevent clotting
palpataing a vein is useful because it aids in determining
the depth of a vein / the direction of a vein / the size of the vein
slanted tip of the needle is known as the
bevel
open space inside the needle described by gauge
lumen
