detergent-containing wipes followed by a sanitizer
What is a venoscope?
transillumination device for locating veins
This guage of needle is used primarily as a transfer needle rather than for blood collection.

made to fill only partially
ETS tube additives are:
clot activators, anticoagulants, silicon gels
Plastic red top tubes used to collect blood specimens contain:
preservatives
This test can be affected by cross-contamination from a light blue top:
calcium
What test might be affected by carryover from an EDTA tube?
creatine kinase
These additives can potentially affect an alkaline phosphate test:
citrate, oxalate, EDTA

diameter
Multisample needles are typically available in these guages.
20-22
The slanted tip of the needle is called the:
bevel
The purpose of the rubber sleeve that covers the tube end of a multi-sample needle is to:
prevent leakage of blood during tube changes
A phlebotomy needle that does not have a safety feature:
musst be used with a holder with a safety feature

microbiology
A royal blue top with green color coding on the label contains:
heparin
What substance is an anticoagulant:
oxalate
It is important to fill oxalate tubes to the stated fill capactiy because excess oxalate:
causes hemolysis of blood specimens
This substance in contained in a serum separator tube?

A prothrombin time (PT) and platelet count are ordered on an 80-year-old female patient. Deciding to use a butterfly and "short draw" evacuated tubes on the tiny cephalic vein on the dorsal side of the right arm, the phlebotomist collects the light blue tube first and the lavender last. Why would you suspect that the PT test results might be incorrect and the platelet count unaffected.
no tube was drawn to remove air in the butterfly tubing
