serum&plasma
liquid in lab tests
| Question | Answer |
|---|---|
| plasma, the liquid portion of uncoagulated blood is about what percent of what | 90% of water |
| what are most lab test done on | plasma or serum |
| what is the liquid portion of coagulated blood | serum |
| with serum, the cells have been allowed to clump together leaving a liquid behind that does not have | fibrinogen |
| serum is just like plasma but | lacks the fibrinogen |
| serum is -------in color and contains all the components of plasma except fibrinogen | straw |
| what section of the lab is serum normally tested in | the chemistry section of the lab |
| how is serum separated from the cells | by allowing the cells to clot |
| all blood will clot unless treated with | an anticoagulant |
| what is the term describing red blood cell destruction | Hemolysis |
| what is the term for a clot of blood that has formed inside the vascular system | Thrombus |
| what is the term for inflammation of the vein | Phlebitis |
| what is the term for buildup of cells within the vascular system and a decrease in plasma | Hemoconcentration |
| what is the term for an infection in the bloodstream | septicemia |
| what is the term for a clot of blood that has formed outside the vascular system | Hematoma |
| what is the term for an increase in potassium levels | Hyerkalemia |
| hardened veins usually as a result of inflammation or specific disease | Sclerosed veins |
| a vein does not have blood flowing through it, either due to a thrombus[clot]or sclerosis[scarring] | Occluded vein |
| veins that do not run straight [looks like squiggly lines under the skin] | Tortuous veins |
| what is a common complication with Geriatric patients due to weak veins | Collapsed veins |
| blood will initially start yo flow into the tube, then stop abruptly | Collapsed veins |
| any additional attempts at venipuncture should occur | below the level of initial attempt |
| the tourniquet should not be left on for more than | one minute |
| leaving the tourniquet on longer then one minute will cause | Hemoconcentration,Hemolysis,and hyperkalemia |
| tying the tourniquet to tight will cause | Petechiae and trauma |
| Petechiae and trauma can lead to | Phlebitis |
| what lab levels may be falsely report in a lab sample with Hemoconcentration | sodium levels decreased,potassium levels elevated,RBC count abnormal due to RBC death,and cell levels[RBC,WBC,Platelet]increase |
| is both an inflammation of the vein and clot formation, usually caused by repeated trauma to the site | Thrombophlebitis |
| a condition in which there is an excessive number of blood cells | Polycythemia |
| retention of fluid in the tissue | Edema |
| insufficient blood flow to deliver oxygen to the tissue | ischemia |
| blockage of coronary arteries can cause | Hypoxia[lack of oxygen],Ischemia[lack of delivery],Infarction[tissue death] |
