Safety Precautions
100

These carry blood away from the heart, have bright red blood, are rich in o2 which is delivered to cells of the body, thicker walls because the blood is under pressure from the heart, and pulse and bp are measurement result when palpate or auscultate blood moving through 

arteries

100

Cut at a slant or "beveled", inserted into the pts vein with bevel in what direction?

needle, facing up

100

How are needle gauges measured? 

larger the gauge number, the smaller the diameter of the needle, meaning a 12 gauge is larger than an 18 gauge needle and a 28 gauge needle is smaller then a 20 gauge

100

What can happen if you use a needle too small?

the blood can lyse

200

Hollow tubes that carry blood through miles and miles in a never ending stream, in an adult can reach 100,000 miles long, they carry blood between heart different tissues and organs, have ability to expand to allow more blood through and can contract to control flow

blood vessels

200

what the blood goes into, made of plastic or glass, sterile on inside, different colored toppers indicating additives in it, stopper creates vacuum seal inside tube, vacuum draws correct amount of blood into tube

vacutainer aka collection tube

200

What does the syringe consist of? Which parts are sterile and cant be touched?

needle hub, barrel, and plunger

needle hub, inside of barrel, and distal part of plunger

200

How long can you leave the tourniquet on for?

no more then 1 minute

300

carry blood TOWARD the heart, has darker red blood because it has given up o2 and taken on co2 and other waste products that will be taken to right side of the heart, increase in size as progress towards heart, follow a path parallel with arteries,more then arteries carry about 70% of blood, contain valves to keep blood going toward heart and backwards between heartbeats

veins

300

plastic device that holds both the needle and the vacutainer, twists snugly into place to secure, is not considered sterile

barrel, vacutainer holder

300

What should label for specimen contain?

patients full name, DOB, date of collection, time of collection, health care workers initials, patients room number

300

How many identifiers do you use when identifying the correct patient?

2

400

very small blood vessels connecting smallest arteries (arterioles) to the small veins (venules), only one cell thick, 02 leaves blood to enter body cells and co2 leaves the body cell to go into the blood

capillaries

400

beveled needle with tubing attached, plastic wings attached to needle on one end and vacutainer holder on other end, used for more difficult venipunctures such as small veins, ped patients, and geriatric patients

butterfly needle

400

Why are bandages not recommended to be put on infants or young children?

they might pick them off put them in their mouth and aspirate on them

400

Whats an important thing to do before blood draw so you collect the right vacutainers?

check md orders

500

What is the sequence of blood flow starting with the heart

heart

arteries

arterioles

capillaries

venules

veins

500

why must the blood collection tubes be drawn in a specific order?

to avoid cross contamination of additives between tubes 

500

How long do you wait for the 70% isopropyl alcohol or alcohol pad to dry on the site before drawing?

30-60 seconds

500

How are cells separated in vacutainer?

Placing container in centrifuge
