Phlebotomy 9 Flashcards
phase of testing that begins when test is ordered and ends when testing begins
preexamination/preanalytical
substance undergoing analysis
analyte
range of values with high/low values for tests that account for patient variation
reference range/reference interval
normal values for reference ranges
normals
resting metabolic state of body early in the morning after fasting for 12 hours
basal state
condition where blood components that cannot easily leave the bloodstream become concentrated in the smaller plasma volume
hemoconcentration
cloudy
turbid
specimen that is milky or turbid instead of transparent, light yellow
lipemic
having 24-hr cycle
circadian
daily
diurnal
yellow, bile pigment that is a product of RBC destruction and breakdown of Hgb
bilirubin
relating to or marked by jaundice, ie. serum, plasma, urine
icteric
posture-related, false anemia; substantial decrease in Hct values from increased plasma
postural pseudoanemia
obstructed
occluded
hardened
sclerosed
clotted
thrombosed
swelling by accumulation of fluid
edema
swelling or mass of blood caused by blood leakage from vessel during/after venipuncture
hematoma
surgical breast removal
mastectomy
swelling from impaired lymph flow
lymphedema
obstruction of stoppage of normal lymph flow
lymphostasis
extremely overweight
obese
longer tourniquets designed for the obese
bariatric
tubing and other devices designed to allow entry into veins/arteries
vascular access device (VAD)
of, pertaining to, or within a vein; quick way to deliver fluids, medications, blood transfusion products, and other substances to patients
intravenous (IV)
device filled with saline
saline lock
catheter placed in an artery
arterial line (A-line)
permanent surgical connection of an artery and vein
arteriovenous (AV) shunt
dialysis shunt by permanent fusion of the artery and vein
AV fistula
shunt created using a piece of a vein or tubing to form a loop from the artery to the vein that can be seen under the skin
AV graft
indwelling line, consisting of tubing inserted into a main vein or artery; used for administering fluids and medication, monitoring pressures, and drawing blood
central vascular device (CVAD)
line inserted into a large vein such as the subclavian and and advanced into the superior vena cava, proximal to the right atrium
central venous line/CVC
small chamber attached to indwelling line surgically implanted in the upper chest or arm
implanted port
a line inserted into peripheral venous system and threaded into the central venous system
peripherally inserted central catheter (PICC)
loss of consciousness and postural tone resulting from insufficient blood flow to the brain
syncope
sudden faintness or loss of consciousness caused by a nervous system response to abrupt pain, stress, or trauma
vasovagal
tiny, non-raised, red, purple, or brownish colored spots that appear on the patient’s skin when a tourniquet is applied
petechiae
low platelet count
thrombocytopenia
adverse condition brought on by the effects of treatment
iatrogenic
blood loss to a point at which life cannot be sustained if more than 10% of blood volume is removed at one point or over a short period of time
exsanguination
stagnation of normal venous blood flow
venous stasis
RBCs damaged or destroyed and Hgb escapes into fluid portion of specimen
hemolysis
