| What are Evacuated Collection Tubes? | Tubes that are designed to fill with a predetermined volume of blood by vacuum. |
| What do the various colors of rubber stoppers indicate on collection tubes? | The rubber stoppers are color coded according to the additive that the tube contains. |
| Why must blood collection tubes be drawn in a specific order? | To avoid cross-contamination of additives between tubes. |
| In order, what are the first 3 blood collection tubes you would use? | First- (Yellow or Yellow- Black top) For blood cultures. Second- (Light Blue Top) Coagulation Third- (Red Top) Non-additive |
| On your last draw, what order of additive tubes would you draw? | 1. SST (red-gray or gold top) 2. Sodium heparin (dark green top) 3. PST (light green top) 4. EDTA (lavender top) 5. ACDA or ACDB (pale yellow top) 6.) Oxalate/fluoride (light gray top) |
| What may be obtained if the blood is not thoroughly mixed with the additive? | Erroneous test results |
| In regards to proper patient identification in what case(s) would you not proceed with drawing the patients blood? | If patient information does not match id armband. If patient is missing id armband. |
| What areas are to be avoided when choosing a site? | Extensive scars The upper extremity on the side of a previous mastectomy Hematoma Above the IV site Intravenous lines Cannula/fistula sites Edematous extremities |
| Where does the tourniquet need to be placed and how long can you leave it on? | 3-4 inches above the selected puncture site No longer than 2 minutes. 1 minute is ideal. |
| If blood stops flowing into the tube during collection what can you do? | Resecure the tourniquet to increase venous filling. If this is not successful, remove the needle, take care of the puncture site, and redraw. |

| What is hemoconcentration? | An increased concentration of larger molecules and formed elements in the blood |
| What can happen if the tourniquet is left on for too long? | Hemoconcentration Increase of protein from tourniquet site down Can affect packed cell volume Can cause hemolysis. |
