test: ETS

Question 1

It is a clear, plastic, disposable cylinder with a small threaded opening at one end (often also called a hub) where the needle is screwed into it and a large opening at the other end where the collection tube is placed.

Answer 1

tube holder

Question 2

It is a closed system in which the patient’s blood flows through a needle inserted into a vein and then directly into a collection tube without being exposed to the air or outside contaminants.

Answer 2

evacuated tube system

Question 3

Can patients request blood tests in their own volition without the doctor’s prescription or request?

Answer 3

Yes

Question 4

Carryover or cross-contamination is the transfer of additive from one tube to the next.

True or False

Answer 4

True

Question 5

Evacuated tubes fill with blood automatically because there is a vacuum (negative pressure) in them. The vacuum is artificially created by pulling air from the tube.

Answer 5

Both statements are correct.

Question 6

ETS needles are called multisample needles because they allow multiple tubes of blood to be collected during a single venipuncture

True or False

Answer 6

True

Question 7

If the additive prevents clotting, the result is a whole-blood specimen. Some whole-blood specimens are used directly for testing; others are centrifuged to separate the cells from the fluid portion called plasma, which is used for testing.

True or False

Answer 7

True

Question 8

A substance present in tissue fluid, activates the extrinsic coagulation pathway and can interfere with coagulation tests. It is picked up by the needle during venipuncture and flushed into the first tube filled during ETS collection, or it is mixed with blood collected in a syringe

Answer 8

Tissue thromboplastin

Question 9

The amount of additive in a tube has been calibrated by the manufacturer to function optimally and produce accurate results with the amount of blood it takes to fill the tube to the capacity or volume indicated.
Specimen quality can be compromised and lead to inaccurate results if the tube is underfilled, so it is important to allow additive tubes to fill with blood until the normal vacuum is exhausted.
