| avoid collecting a specimen from an arm on the same side as a mastectomy because | arm is usually edematous, effects of lymphostasis may cause erroneous results, and veins in that arm may collapse more easily |

| a type of line that is commonly used to collect blood gas specimans | arterial line |
| a vascular access pathway that is surgically created to provide access for dialysis is called? | arteriovenous (AV) shunt |
| when a blood specimen is collected from a heparin lock, it is important to draw | a 5 ml dicard tube before collecting the specimen |

| you are in the process of collecting a blood specimen. Blood flow has been established. As the the tube is filling, you hear ahissing sound and there is a spurt of blood into the tube and the flow then stops. What has most likely happened is: | needle bevel came partly out of the skin and vacuum escaped from the tube |
| which of the following situations could indicate that the needle has gone through the vein? | fail to get blood flow until you pull back on the needle, felt the needle go into the vein but you fail to get blood flow, and filled one tube but the second one failed to fill with blood |
| you are in the process of collecting a specimen. The needle is inserted but blood is filling the tube very slowly. You see a hematoma forming very rapidly. What has most likely happend is | the needle only partly inserted in the vein |
| performing a multi-tube blood draw. the first tube collects w/out a problem. second tube fails to fill. You adjust the needle and rotate bevel nothing happens. What should you do? | discontinue the draw and try at another site |
