b. 7.35-7.45
c. 7.30-7.40

Answer 2

7.35 - 7.45

average- 7.40

Question 3

whole blood specific gravity

a. 1.024-1.029
b. 1.045 - 1.066
c. 1.025 - 1.029

Answer 3

blood specific gravity

a. 1.024-1.029 = serum
b. 1.045 - 1.066 = WHOLE BLOOD
c. 1.025 - 1.029 = plasma

Question 4

color of pulmonart artery

a. bright red
b. dark purple red

Answer 4

pulmonary artery = dark purple red

pulmonary vein = bright red

it is reversed in oxy and deoxy blood

Question 5

arterial blood color

a. bright red
b. dark purplish red

Answer 5

arterial/ oxygenated blood = bright red

venous / deoxygenated blood = dark purplish red

Question 6

it is the CONCENTRATION OF SOLUTES DISSOLOVE IN THE BLOOD

a. specific gravity
b. osmometer
c. osmolality

Answer 6

osmolality

Question 7

what instrument to use in measuring the osmolality

Answer 7

osmometer

Question 8

disodium salt is also knows as?

a. versene
b. sequestrene

Answer 8

versene = disodium salt

sequestrene = tri potassium salt

Question 9

its mode of action is to remove ionized calcium tru the process of chelation

a. edta
b. heparin
c. oxalate

Answer 9

edta

edta- its mode of action is to remove ionized calcium tru the process of chelation. chelation forms a insoluble calcium salt to prevent blood coagulation

Question 10

its appearance is SLIGHTLY HAZY

a. plasma
b. serum

Answer 10

plasma - slightly hazy

serum - clear appearance

Question 11

fluid portion of NON ANTICOAGULATED blood

a. serum
b. . plasma

Answer 11

serum = fluid portion of non anticoagulated blood

plasma = fluid portion of anticoagulated blood

Question 12

ratio of blood to anticoagulant (sodium citrate) for black top

a. 9:1
b. 1:4
c. 4:1

Answer 12

ratio of blood to anticoagulant (Standard Westergren / Black top) == 4:1

ratio of blood to anticoagulant (coagulation) = 9:1

Question 13

action is to bind calcium and form INSOLUBLE complex

a. edta
b. sodium citrate
c. oxalate

Answer 13

oxalate - binds calciums and form INSOLUBLE OXALATE

edta & sodium citrate - binds calcium and form soluble complex

Question 14

anticoagulant with the action : an acid mucopolysaccharide that inhibits coagulation by inactivation of thrombin

a. sodium oxalte
b. sodium citrate
c. heparin

Answer 14

hepatin

Question 15

it produces BLUISH BACKGROUND ON ROMANOWSKY STAIN

A. OXALTE
B. EDTA
C. HEPARIN

Answer 15

HEPARIN

Question 16

anticoagulant used in BLOOD BANK STUDIES, LYMPHOTOTOXICITY TESTING, HLA PHENOTYPING, DNA ANDPATERNITY TESTING

a. sodium fluoride
b. acid citrate dextrose (acd)
c. heparin

Answer 16

YELLOW TUBE/STOPPER 😊
>Sodium polyanethol sulfonate (SPS) -for blood culture specimen collections in microbiology.
-First tube in the sequence of order of draw

> Acid Citrate Dextrose (ACD) - used in blood bank studies, Lymphocytotoxicity testing, HLA phenotyping, and DNA and paternity testing.
-Last tube in the sequence of order of draw

Question 17

most common phlebotomy complications

a. dermatological
b. infectious complications
c. vascular complications

Answer 17

vascular complications

Question 18

it is a vascular complication that is FIBROUS CAPSULE AROUND ENCAPSULATED BLOOD CAUSED BY A BREAK IN BLOOD VESSEL

a. bruising
b. thrombosis
c. pseudoaneurysm

Answer 18

pseudoaneurysm

Question 19

it is a vascular complication that is abnormal connection between the vein and artery can occur after repeated venipuncture

a. arteriovenous fistula
b. hematoma
c. bruishing

Answer 19

arteriovenous fistula

Question 20

vascular complication that is result when leakage of LARGE AMOUNT of blood around the puncture site causes the area to rapidly swell

a. hematoma
b. thrombosis
c. bruising

Answer 20

hematoma - leakage of LARGE AMOUNT of blood around the puncture site causes the area to rapidly swell

bruising (ecchymosis) - it is caused by SMALL AMOUNT of blood in the TISSUE around the puncture site
