Serum

2

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

In the dorsal side of hands and wrist

3

The instrument used to spend the removal of sun by Spinning the blood is called

Centrifuge

4

Before performing a venipuncture, a pair of clean gloves should be put on in the presence of a patient because

It is a reassuring safety- conscious gesture for both the patient and the worker

5

The supine position refers to

Lying face up on their back

6

To avoid- clotting in the blood collection tube

It is extremity important that the blood collected in a purple- topped tube be gently inverted a minimum of eight times

7

The blood PH range of the normal body is

7.35 to 7.45

8

Serum should be transported to the laboratory for

Testing and separated from blood cells within 2hrs

9

Liquid makes up

55% of the total volume of the blood

10

A person who has to little hemoglobin or a decreased number of red blood cells is know to be

Anemic

11

The blood cells begin their formation in the

Lymph nodes and bone marrow

12

13

The iron containing pigment of the blood cells is called

Hemoglobin

14

Once they enterthe bloodstream, mature red blood cells live approximately

120 days

15

The study of the nature and cause of disease is known as

Pathology

16

A special labeled puncture- resistant container for the disposal of needles, scalpels, and syringes is known as

Sharps container

17

When drawing bllod, the vein that is most preferred is

The median cubital

18

If blood pressure is read as 120/80, the 120 is the

Systolic pressure

19

The systolic pressure is the pressure when the heart is

Contracted

20

A chemical cryusdante substance that prevents the blood from clotting is called an

Anticoagulant

21

Homeostasis refers to

The steady- state condition

22

Handwritten information cannot be converted into

Code symbols

23

Interstitial fluid is

Tissue fluid

24

Fragile veins are most likely to be found in

Geriatric patients

25

After a finger stick is performed, the phlebotomist should

Wipe away the first step of blood

26

The best angle for spreading a blood smear is by

Using two glass slides at 30 degrees

27

Skin puncture samples are often used for

White blood cell differentials

28

During a skin puncture procedure, the cut should be

Across the fingerprint lines

29

In most cases, blood collected to determine medication levels should be collected

Just prior to the next dose of medication

30

In relation to veins, the term occluded means

Obstructed

31

The thumb has a

Pulse

32

The last step in any phlebotomy procedure, including skin puncture is checking that

The bleeding has stopped and thanking the patient for cooperating

33

Alcohol should be allowed to dry for

30 to 60 seconds before the venipuncture

34

During the venipuncture, the best angle for inserting the needle into to the skin is

15 to 30 degrees

35

During the venipuncture, the phlebotomist releases the tourniquet

After the needle is inserted and the blood begins to flow

36

The term "butterfly" refers to a

Winged infusion set

37

During the venipuncture procedure, the needle should always be inserted with the

Bevel side up

38

Blood and urine specimens for microbiological cultures should be transported to the lab quickly to improve

The likelihood of defoliation pathogens

39

Normal blood specimens take __________ to clot

30 to 60 minutes

40

Bar codes in phlebotomy applications are not used to

Denote patient arm preference

41

The preferred anticoagulant for the collection of whole blood foot STAT situations in clinical chemistry is

Heparin

42

44

Fire newborns, the penetration depth of Lancets for blood must be
