capillary puncture
venipuncture
arterial puncture

2

best method of blood collection for newborns and babies

capillary or skin punc

3

method of blood collection seldom used for aged individuals

capillary or skin punc

4

method of blood collection wherein sx usually used for chemistry analysis

venipuncture

5

sites of puncture in venipuncture

basilic vein
cephalic vein
median vein

6

vein for venipuncture pointed toward the body

basilic vein

7

vein for venipuncture pointed away the body

cephalic vein

8

used in the analysis if pO2, pCO2, blood pH

arterial blood

9

method of blood collection not done by ordinary RMTs

arterial puncture

10

sites of arterial puncture

brachial, femoral, radial artery

11

how to label specimen

last name, first name, MI
specimen or patient no.

12

when to label specimen

after collection/filling up the tube

13

number 1 reason of specimen rejection

hemolysis

14

in serum what ions are abundant

Na and Cl

15

inside cell what ions are abundant (and their ratios)

K (20:1)
Mg (10:1)

16

hemolysis of RBC leads to

false elevation of analyte concentration

17

straw colored yellow fluid

serum

18

liquid portion of clotted blood

serum

19

temperature of blood for test of CK

cold temp

20

temperature of Sx for LD

room temp

21

reasons of rejection

questionable labelling
hemolysis
QNS

22

Substance added to blood to prevent clotting

Anticoagulant

23

mechanism of action of anticoagulant

1) can precipitate, bind, complex Ca thus Ca is removed
2) by acting as antithrombin

24

stages of clotting process

generation of thromboplastin
conversion of prothrombin to thrombin
conversion of fibrinogen to fibrin clot

25

Ca dependent stage of clotting process

generation of thromboplastin

26

Thromboplastin dependent stage of clotting process

conversion of prothrombin to thrombin

27

thrombin dependent stage of clotting process

conversion of fibrinogen to fibrin clot
