Day 1 Flashcards
Ethical behavior
Under patient bill of rights, always have option to decline treatment and know test being performed on them. DONT EVER GIVE THEM THE RESULTS bc not qualified. Failure to give appropriate care is negligence. Don’t write diagnosis on blood tubes.
Phlebotomy
Incision into vein
Role of phlebotomist
Draw blood from circulatory system
What is Quality Assurance defined as
Scheduled audits
Site selection
Based on the size and condition of the vein.
Median cubit vein
Most commonly used
Cephalic vein
More difficult to located, can move, easiest to palpate in obese person.
Valves
Only veins have. Maintain one way flow of blood.
Laboratory requisition
Labels incl an accession number> unique tracking number that is different for each sample.
Tourniquet
Slow venous outflow from arm causing veins to bulge>easier to locate. 4-6 in above puncture site. Should remain on for the entire length of draw.
Gloves
Always worn
Vacutainer needles
Needles smaller than 23 gauge not used because of risk of hemolysis.
Winged infusion set
Also called butterfly needle.
Needle disposal
Never recap a needle. Proper disposal is safety cap and put in sharps container after withdrawing from arm.
Most critical mistake
Failing to properly ID the patient.
Concentric
Circular motion start in center and spiral out.
Bevel faces
Upward
Pressure applied until
Bleeding stops
The proper steps to complete a blood draw are
Tourniquet, tube, cotton ball and safety cap and apply pressure
Capillary
Microscopic blood vessel
Risk of excessive milking
Hemolysis and contamination of site with tissue fluids. Warming site helps.
Site selection in infant foot.
imaginary lines middle of great toe to heel and btw 4/5 toes, fatty pads on outside of heel. Don’t go deeper than 2.0 mm. Always wipe first drop of blood away. Or urine
Edema
Excess h2o in tissue under skin.
Syncope
Fainting (syncopal). If patient faint first thing to do is to get needle out of arm.
Hemoconcentration
Tourniquet on too long.
Hemostasis and vascular phase
Healing process. Injury to blood vessel causes it to constrict. Slowing blood flow
Antecubital fossa
Bend in elbow.
Purpose of anchoring a vein
So it will not move.
Sclerosed vein
Thickened walls scarred/hardened tissue
