29
The larger the syringe, the greater the amount of _____ obtained
vacuum
30
A transfer device must be ____ when tubes are being filled in order to prevent blood in the tube from touching the needle in the transfer device.
vertical
31
- Short needle with a thin tube with attached plastic wings - Used for infants and children and patients with fragile veins (cancer patients)
Winged infusion sets
32
- Help place and remove tubes - Has an indentation about ¼ inch
Tube holder/ needle adapter
33
- Preserve a specific blood constituent - Used to improve sample quality or accelerate sample processing - Aid in the separation of serum from cell
Tube additives
34
- Chelates or precipitates Calcium - Inhibits thrombin activity
Anticoagulants
35
Most common anticoagulants used:
- Ethylenediaminetetraacetic acid (EDTA) - Citrate - Heparin - Oxalate
36
How many inversions of EDTA?
8-10
37
uses of EDTA? color of tube?
hematology test, blood collection lavender
38
how many inversions for Citrate? color o tube?
3-4, light blue
39
40
aka Mucoitin Polysulfuric acid - Ideal universal anticoagulant - Naturally occurring anticoagulant color of tube and how many inversions?
heparin, green, 8-10
41
this anticoagulant is used for situation that needs a fast turnaround time
Heparin
42
- Combines with Calcium to form an insoluble salt. - temperature sensitive anticoagulant
oxalates
43
44
- Forming weakly dissociated calcium components - weak anticoagulant tube color?
fluoride, gray
45
- Gold Top - Design to help isolate/ separate the serum to cell composition
Serum Separator Tube
46
White Top - In order of draw: After SST or before Heparinized tube
Plasma Separator Tube
47
what is the additive in orange tube?
thrombin
48
- Additive free tubes - Mostly for clearing or discard purposes - Yields serum sample
red tube
49
Order in which tubes are collected during multiple draw or are filled from a syringe
1. Sterile blood culture tubes- Yellow 2. Coagulation tubes- Light blueSerum tube/ 3. Plain tube- Red 4. Heparin tube- Green 5. EDTA tube- Lavander/Purple 6. Anti-glycolytic tube/ Fluoride- Gray If SST or PST is available or needed, after 3rd tube or before Heparinized tube
50
Transfer of additive from one tube to the next Occurs when: - Blood in additive tube touches the needle during ETS blood collection - When blood is transferred from a syringe into ETS tube
Carry over/ Cross Contamination
51
- Complete system for blood collection - Blood collection tube and collection apparatus combined in a single unit - Either: ETS or Syringe technique
Combination System
52
true or false in skin puncture, filling of capillary tube is done rapidly
true
53
cut orientation when doing skin punctue?
across the fingertips
54
2 types: - Automatically punctures the skin - Phleb pushes the blade
retractable lancets
55
An anticoagulant is an additive placed in evacuated tubes in order to
prevent the blood from clotting
56
When serum is needed for testing, blood must be collected in which of the following colored tubes?
Red (d q sure sabi lng ni chatgpt i2 hshsh)
57
Leaving the torniquet on a patient’s arm for an extended length of time before drawing blood may cause
