1. The three main categories of resources available to you regarding laboratory testing and results are

Green Laboratory Manual, CMC Policy and Clinical Practice Manual, Nursing and

Clinical Laboratory Staff

The primary difference between serum and plasma is

. Plasma contains fibrinogen and serum does not

It is critical that the Light Blue-topped tube is filled properly in order to get accurate patient results. Why?

The reference values for coagulation studies are based on the 9 parts blood to 1 part anticoagulant ratio.

4.In order to collect an effective finger stick sample with the least amount of trauma, which fingers are the best choice?

2nd and 3rd (middle and ring fingers)

For finger stick samples, which test would be collected first?

. Lavender ( important for platelet counts)

6.A primary cause for a specimen to be hemolyzed is

a.Using a 25 gauge needle with a 12 CC syringe, pulling forcefully to obtain the specimen b.Moving the needle laterally to try to locate the vein (probing) c.Not allowing the alcohol/cleanser to dry before venipuncture

7. Hematology tests (ex, CBC, WBC, Platelets) are collected in tubes containing EDTA because it helps preserve cellular morphology. EDTA is the anticoagulant in the

Lavender tubes

. A BMP (Basic Metabolic Package) is routinely collected in a

Gold (gel separator), red top tube or brown bullet

Coagulation tests (ex: PT, PTT, Fibrinogen) are collected in a

Light Blue tube

. Blood bank specimens ( Type and Cross match, ABO) are collected in which tube?

Lavender

The blood cultures, when ordered with other tests, are always collected first in the standard

To prevent contamination

. In the “order of draw” (evacuated or syringe), blood is put into the collection tubes in this order

Sterile (blood culture), Light Blue, Red, Green, Lavender, Gray

All patient specimen test tubes must have this information on each tube:

Patient name, date and time of collection, collector’s initials and identifying numbers

Blood bank specimens must

Have hand-written labels

. Requisitions (either computer-generated or manual) must contain

. Patient’s name, Location, Ordering MD

b. Patient History Number, Test to be ordered, Date and time of collection

. Laboratory specimens are labeled only

At the bedside at time of collection (after the blood is in the tubes)

. In performing a proper finger stick, why is it important to ALWAYS wipe away the first drop of blood?

Prevent the specimen from being contaminated with tissue fluid

18.A heel stick is never performed at the posterior curvature of the heel. Why?

To prevent damage to the calcaneous (and risk puncturing the bone)

19.Heel sticks are performed on infants

a.Up to one year old

20.Tests that cannot be performed by heel stick or finger stick include

. Erythrocyte sedimentation rate, coagulation studies, blood cultures
