| What special handling does a billirubin specimen require? | Protect from light. (Goes in Amber colored tube for infants.) |
| The BEST way to avoid reflux is: | Ensure the tube fills from the bottom up. |
| For which of the following tubes is the blood to anticoagulant ratio most critical? | Light Blue stopper. |
| The recommeneded angle of needle insertion for routine venipuncture is between: | 15 to 30 degrees. |
| The tourniquet must not be on longer than: | 1 minute. |

| Which of the following is not a safe site for heel punture? | posterior curvature of the heel. |
| Where do you draw blood from on an infant? | On the medial and later curvature of the heel. |
| Damage to the red blood cells and release of hemoglobin into the serum or plasma is called: | Hemolysis |
| The Silica in an SST: | Activates and enhances clotting. |
| Which test is most affected by tissue fluid contamination? | Protime |
| What is the advantage of collecting stat chemistries in green stopper tubes? | The test can be performed sooner. |
| Which anticoagulant inhibits thrombin formation? | Heparin. |
| Which of the following tests is most commonly ordered on patients with FUO? | Blood cultures. |
| The substance normally used to clean a site prior to routine venipuncture is: | 70% isopropyl alcohol. |
| The yellow topped vaccuum collection tube has which of the following additives? | Sodium polyanetholesulfonate (SPS) |
| The butterfly blood collection set is frequently used with the needle gauge size of : | 23 |

| A prefilled device used as a collection and dilution unit is the : | BD Unopette |
| Acid-Citrate-dextrose (ACD) | An additive commonly used in specimen collection for blood donations to prevent clotting. It ensures that the RBC's maintain their oxygen-carrying capacity. |
| Anticoagulants | Substance introduced into the blood or a blood specimen to keep it from clotting. |
| Capillary Tubes | Disposable narrow-bore pipettes that are used for pediatric blood collections and/or microhematocrit measures. The tubes may be coated with anticoagulant such as heparin, and for safety reasons are usually made of plastic. |
| Citrates | Type if anticoagulant additive for blood collection tubes prevents the blood clotting sequence by removing calcium and forming calcium salts. |
| Disposable sterile Lancets | Steril sharp device, preferable retractable, used in skin puncture collections to penetrate the skin at specified depths (e.g., no more than 2.0 mm for infant heelsticks). |
| ethylenediamine tetra-acetic acid (EDTA) | Anticoagulant additive used to prevent the blood-clotting sequence by removing calcium and forming calcium salts. EDTA prevents platelet aggregation and is useful for platelet counts and platelet function tests. |
| EDTA (ethylenediaming tetra-acetic acid | (continuing) Fresh EDTA samples are also useful for making blood films or microscopic slides, because there is minimal distorition of platelets and WBC's |
| gauge number | Size (diameter) of the internal bore of a needle. |
| heparin | Anticoagulant that prevents blood clotting by inactivating thrombin and thromboplastin, the blood clotting chemicals in the body. |
| Holder Adapter | Plastic Apparutua needed in specimen colleting using the evacuated tube method. |
| Lithium iodoacetate | Antiglycolytic agent and anticoagulant; not to be used for hematology testing or enzymatic determinations. |
| Micorcontainers |
