Question | Answer |
---|---|
Required on EVERY specimen label | 1. Name, 2. DOB or MRN (medical record number), 3. Date, 4. Time (military), 5 Phlebotomist's Initials |
Items on your tray | Gauze, alcohol wipes, tubes, band-aids or tape, device (syringe, butterfly, vacutainer) tournquet |
Purpose of a tourniquet | makes vein easier to feel. Constict venous flow out not arterial in |
How long can a tourniquet be left on | 1 min max! |
If the tourniquet is left on longer than 1 min | hemoconcentration |
Where should the tourniquet be place in relation to the intended site of puncture? | 3-4 inches above |
Desired veins to choose from | Median cubital - center of bend in arm, Cephalic vein - thumb side, Basilic - pinky side - median nerve and brachial artery - not drawn in class |
Evacuated tubes containing an anticoagulant additive must be gently mixed to | prevent blood from clotting |
Characteristics of veins | carry deoxygenated blood, have valves (the blood is NOT under pressure) Within the vein muscle facilitate the movement of blood and valves prevent backflow |
A butterfly needle is used for | drawing from fragile veins, drawing small veins, drawing from veins in the hand (used for more control) |
Proper procedure when cleansing a venipuncture site is | rub the site with alcohol in an outward, spiraling motion and allow 30-60 seconds to dry before the puncture. |
What angle should a needle be inserted at | 15-30 degrees |
In order to prevent mislabeling, the tubes are labeled | after blood is drawn and patient is still present |
Chemical used to clean human skin by inhibiting the growth of microorganisms | antiseptic |
Components of the chain of infection | Pathogen, Reservoir, Portal of Exit, Mode of Transmission, Portal of Entry, Susceptible Host |
3 ways to get a blood sample | capillary, venipuncture, arterial |
What things are important in vein selection? | size, depth, direction |
Fibrinogen | A blood clotting factor |
Serum | Blood specimen that does not contain an anticoagulant |
Antecubital | Near the bend of the elbow |
Hemolysis | Rupture or lysis of the blood cells |
Median Cubital Vein | Best vein to use for venipuncture |
Arteries | Vessels that carry blood away from the heart |
Basilic Vein | Alternate vein to use for venipuncture. Last choice when no other vein is available. |
Veins | Branching vessels that flow back to the heart. |
Anticoagulant | Substance introduces in to the blood or a blood specimen to keep it from clotting. |
Tourniquet | A soft rubber strip used on the arm to help find a venipuncture site. |
Hemostasis | Blood-clotting process in the body |
Plasma | Blood specimen that does contain an anticoagulant |
Saphenous vein | The longest vessel in the body |
Hematoma | Leakage of blood into surrounding tissue |
Capillary | Contains a mixture of arterial and venous blood |
Citrates | Type of anticoagulant additive for blood collection tubes, prevents the blood clotting sequence by removing calcium and forming calcium salts |
Gauge Number | Refers to the size (diameter) of the internal bore (opening) of a needle |
Glycolytic inhibitor | An additive used in collection tubes that prevents glycolysis |
Heparin | An anticoagulant that prevents blood clotting by inactivating thrombin and thromboplastin, the blood-clotting chemicals in the body |
Syncope | The transient (and frequently sudden) loss of consciousness due to the lack of oxygen to the brain (fainting) and resulting in the inability to stay in an upright position |
