Case 1: Charles is a phlebotomist who works in the positions office laboratory. One morning shortly after the drawing station opens, he was asked to collect blood specimens for a CBC and a glucose test from a very heavyset woman who appears quite ill. The patient told Charles that she vomited all night and was unable to eat or drink anything. She also mentioned that she has had a mastectomy on the left side and the last time she had blood collected was very difficult before phlebotomist was able to collect a specimen. 41. Which arm should Charles collect a blood sample? A.Right B.Left C.Either D. Neither 42. What options does Charles have if he is unable to collect a proper venipuncture site?" A. Consider arterial puncture B.Consider capillary puncture C.Repeat the procedure some other time D.Nothing 43. What complication/s might Charles expect? A.Syncope B.Dehydration C.Overweight D.All of the above 44. What must he do to prevent it?* A.Ask the patient to drink water and lie down B.Ask the patient to drink water C.Ask the patient to lie down D.Ask the patient to return some other time Case 2: A phlebotomist name Sarah is in the process of collecting a pro time and CBC from a patient. The needle is in the patient's vein. As Sarah pushes the first tube onto the needle in the tube holder, there is a spurt of blood into the tube, and she hears a hissing sound. Then the blood stops flowing. She-re-positions the needle but is not able to reestablish blood flow. 45. Why did blood spurt into the tube then stop?" A.The tube lost vacuum B.The tube may have been partially in the vein C.Both D.Neither 46. What clues are there to determine the problem?" A.The hissing sound B.Spurt of blood C.Blood stops flowing D.A and C 47. What can Sarah do to correct the problem?" A.Replace the tube B.Repeat the whole procedure C.Twist the tube to reestablish flow D.Remove the tourniquet 51. The range of values normal for a physiologic measurement in healthy persons." A.Basal state B.Reference range C.Normal line D.All of the choices 58.Spontaneous loss of consciousness A.Syncope B.Fainting C.Insufficient blood flow to the brain D.All of the above 59.

Refers to a portion of a sample specimen taken testing.* A.Buffer B.Serum C.Aliquot D.Plasma 60. Thin plastic tube inserted into a vein in the forearm to inject a volume of fluid into the bloodstream." A.Catheter B.Intravenous C.Both D.Neither 61. Excess EDTA may cause...
