Blood Collection Flashcards
The larger the gauge number, the smaller the needle bore.
T or F?
T

T or F?
F

(A)red-gray or gold
(B)Contains gel at the bottom to separate blood from serum and clot activator
Sodium Heparin
(1) color cover
(2) mode of action
(1) Dark green
(2) Inactivates thrombin and thromboplastin
PST (Plasma Separating Tube)

(2) mode of action
(1) Lithium heparin, light green
(2) Anticoagulates with lithium; Plasma is separated with PST gel at the bottom of the tube
EDTA
(1) mode of action
(2) purposes
(1) Forms calcium salts to remove calcium
(2) Hematology (CBC) and Bloodbank (Crossmatch)requires full draw

Anti-glycolytic agent preserves glucose up to 5 days
Applicable for which additives?

Location of phlebotomy site
Heel of the foot - medial and lateral portion of the plantar surface
All are microsampling technique advantages except:
A.Useful in blood extraction in infants less than 6 months
B.Young children when small amount of blood is needed
C.Adults with poor veins or with several intravenous infusions
D.Severely frozen patients
D
Severely burned patients
False about microsampling technique precautions
A.use the tip of the finger or the center of the finger
B.Avoid puncturing a finger that is cold or cyanotic (poor blood supply), swollen, scarred, or covered with a rash
C.Avoid using the side of the finger D.The 5th finger tends to have less soft tissue overlying the bone
A
Do not use
Which is not true?
A.In Microsampling technique, there is no venous and arterial blood mixing.
B.This method can also be used in the assessment of Arterial Blood Gas (ABG)
C. Do not use big toe, tongue and earlobe as puncture site.
A
used to measure oxygen, carbon dioxide and pH of blood
Arterial puncture
Enumerate 3 most common sites for arterial puncture
Brachial artery, radial artery or femoral artery
False about indwelling lines/catheters
A.Potential source of test error
B.Most lines are flushed with a solution of warfarin to reduce the risk of thrombosis
C. Discard a sample at least three times the volume of the line before a specimen is obtained for analysis
B
Heparin dapat
False about hematoma prevention
A.Puncture only the downmost wall of the vein
B.Remove the tourniquet before removing the needle
C.Use the major superficial veins D.Apply pressure to the venipuncture site
A
Uppermost dapat
Prolonged tourniquet application may lead to significant increases in some tests. Enumerate!
total protein, aspartate aminotransferase (AST), total lipids, cholesterol, iron
The creatinine kinase (CK), AST, lactate dehydrogenase (LDH) and platelet count may decrease due to exercise
T or F?
F
Decrease dapat
Enzymes, proteins, lipids, iron, and calcium are significantly___ with changes in position (increased, decreased)
Increased
False about Evacuated collection tubes A.Designed to fill with any volume of blood
B.Rubber stoppers are color coded C.Blood should NEVER be poured from one tube to another
A
Predetermined dapat
