FINAL Flashcards
liquid portion of blood after clotting fibrigen within clot
seum
liquid portion w/o cells after being spun down w anti coag
plasma
primary function of anticoag sodium fluoride
inhibit glycolysis
state anticoag
1 hematology
2 coag
3 chemistry
1 EDTA
2 sodium citrate
3 heparin
why not freeze blood
RBCs will hemolyze
2 reason patients placed in isolation
1 protect staff visitors other patients from patient
2 to patient from others
How EDTA prevent clotting
by binding or chelting calcium
how heparin prevent clotting
inhibits conversion of prothrombin to thrombin
1sites for capillary punture
2 NOT capillary punture this
3 preferred area of finger
1 middle or ring finger
2 earlobe
3 perpendicular to fingerprint
collection of blood under skin from poor venipuncture may cause
2 things this causes
hematoma
pushing through the vein
partially inserting needle in vein
purpose of removing tube from needle prior to vein
release vacuum on tube
consequences of pushing tube onto needle before vein
blow vacuum on tube
what do clot activators do
name 4 ex
enhance coaug
siliceous earth
glass
sillca
thrombin
why does order of draw exist
avoid cross contamination
sclerosed vein feels
do u use
hard cordlike
no
excess fluid in tissue swelling
edema
connection of artery and vein
why important to consider when deciding venipuncture
fistula
used for dialysis and can’t used on arm this was done
slanted needle tip
abnormalities in them 2
bevel
bent tip spurs
why are therapeutic drug monitoring tests often timed collect testing
monitor different times
max drug effectiveness to prevent toxicity
metabolize drugs at different rate
anatomical term for the heel bone
calcaneus
skin puncture blood most closely resemble
arterial blood
why routine or strict isolation used
PPE used
prevent spread communicable diseases
gowns mask gloves
purpose of protective or reverse isloation
patients of this type isolation recommended cause
PPE
protect patient from being infected
anyone immunosuppressed or compromised
gown mask gloves head and shoes booties
abnormal retraction of blood vessel wall causes
vein collapse
