discuss the importance of the order of draw. What problems may surface if the order of draw is not followed when collecting a blood specimen from a patient? How will this be an inconvenience to both the patient and practice?
Weegy: Introduction Proper sample collection and handling is an integral part of obtaining a valid and timely laboratory test result. [ Specimens must be obtained using proper phlebotomy techniques, collected in the proper container, correctly labeled (in the presence of the patient) and promptly transported to the laboratory. It is the policy of the laboratory to reject samples when there is failure to follow these guidelines. All specimens should be handled with universal precautions, as if they are hazardous and infectious. patient Preparation Prior to each collection, review the appropriate test description, including the specimen type to be collected, the volume, the procedure, the collection materials, and the storage and handling instructions. Specimen Collection Timing The basal state (the early morning approximately 12 hours after the last ingestion of food) is recommended for determining the concentration of body constituents such as glucose, cholesterol, triglycerides, electrolytes, and proteins. Blood composition is significantly altered after consuming food, and consequently alters many clinical chemistry tests. If a patient has eaten, and the physician still wants the test, then "non-fasting" is written on the request so the laboratory can make a notation on the report as to why some of the test values may be different than expected. For outpatients, provide the patient in advance with appropriate collection instructions and information on fasting, diet, and medication restrictions when necessary. Specimens for Coagulation Testing Specimens obtained for Coagulation testing must be collected and transported to the laboratory according to strict guidelines in order to assure accuracy of results. ] (More)

________ is the medical term for blood cell production. (Points : 2) hematoma hematopoiesis hemostasis hematosis
Weegy: Hematopoiesis is the process used to create new blood cells to replace those that are aging, and it is continually in progress in the human body. [ [ It involves developing immature cells, known as precursor cells, into working blood cells that help the body to fight infection, prevent excess bleeding and carry oxygen to tissues. Several types of blood cells exist, and the body follows specific pathways to create each type. A stem cell acts as the initial foundation to create mature cells through hematopoiesis. The body creates new blood cells in various locations, depending on a person?s age. During fetal development, hematopoiesis occurs in the liver, spleen and bone marrow. After birth and through development, the bone marrow takes over as the main site of blood cell formation; by adulthood, hematopoiesis occurs in several main sites. These include the skull, the sternum, the vertebrae in the back, the pelvis and the bones of the upper thigh. ] ] (More)
