Palpating the entire antecubital area to trace vein path

5

Arteries differ from veins in which of the following ways

Tend to be lipemic
Smaller in diametwer

Bluer in color

6

If arm veins cannot be used for a venipuncture, the preferred alternative veins lie in the:

Using the early-morning specimens for laboratory testing

13

Why is it important to get patient information about latex sensitivity

This information is only important for the phlebotomist, not the patient
Patients usually have preferences for special tourniquets
Laboratory tests can be affected by the ingestion of latex spnsitivity
Allergies to latex cause skin irritations

14

Steps in the identification process should include:

Forget alternate sites and do a fingerstick on the right hand

17

One reason for hematoma formation during venipuncture is that the

Needle is partially inserted in the vein
Medial cubital vein is used
Needle is too small

20

When using the syringe method to collect a blood specimen, how is the blood added into additive and nonadditive tubes

The needle is removed from the syringe, the caps are removed from tubes, and blood is pushed into each tube, then re-stoppered and mixed.
Using a clean needle puncture all tube to release the vacuum than remove the caps and gently fill each tube
The syringe needle is used to puncture the cap of each tube than blood is pushed into each tube
Using a syringe transfer device attached to the syringe, insert each tube into the device and allow the blood to flow freely

21

Sodium citrate
EDTA
Heparin
Serum tube with clot activator

22

EDTA
Sodium citrate
Serum tube with clot activator
Heparin

23

I am a licensed CLS for forty plus years. Your answerf for #3 is wrong, a pressure cuff is not used (tourniquet). #17 is not quite right, Many times a vein is partially entered, causing a hematoma. #24 is wrong, it used to be done that way, but drawing directly into the blue top is fine.
