Chapter 7: Blood Collection Equipment, Additives, and Order of Draw 137 Case Studies Case Study 7-1: Butterfly Use and Order of Draw Maria, who was recently hired in her first job an a nhlebotomist, has been sent to the ICU to collect a stat hemoglobin and hematocrit (H&H) and protime on a patient. The patient is an elderly woman whose Jeft arm has an intravenous (IV) line. Maria checks the right arm and finds a small but suitable vein, She decides to use a butterfly with the evacuated tube system and selects the following tubes from her blood collecti protime, which is a coagulation test, and a lavender top for the H&H, which is a hematology test. The patient's nurse asks Maria how long she thinks it will take because she wants to give the patient a shot in that arm. Maria tells her that she has only two tubes to collect, so it shouldn't take long. The nurse leaves. Maria makes a successful venipuncture, fills the light-blue-topped tube and mixes it gently by inverting it four times. Then she fills the lavender-top tube. After finishing the draw, properly labeling the tubes, and checking and bandaging her patient, she returns to the lab. Specimen processing immediately rejects the protime and asks her to recollecet it. QUESTIONS equipment carrier: a light-blue top for the 1. Why do you think specimen processing rejected the protime? 2. How did the way Maria collected the specimen cause the problem? 3. Why does the lab reject tubes with this problem? 4, What can Maria do differently when she recollects the specimen? Case Study 7-2: Syringe Use and Order of Draw A phlebotomist named Jeff has a request to collect a CBC on a postop patient. He has drawn the patient before and is aware that the patient is a "difficult" draw. He elects to use a 5-ml. syringe and a 22-gauge needle on a small cephalic vein on the patient's right arm. The venipuncture is successful, and Jeff is in the middle of filling the syringe when the patient's nurse enters the room and tells him that the patient's physician wants to add electrolytes to the request. Jeff tells her that it is not a problem; he will collect a green-top tube also. He finishes the draw, attaches a transfer device, and quickly grabs the smallest tubes he can find, a 3-mL green top for the electrolytes and a 3-mL lavender top for the CBC. He puts 2 mL of blood into the green top and then 3 mL into the lavender top. He labels the tubes and writes "difficult draw" on the green top. Later a chemistry technician tells him that the patient's sodium results are off the wall and contamination is suspected. He is asked to redraw the specimen. QUESTIONS 1. Could the problem have to do with the order of draw? Why or why not? 2. What else could have caused the problem? 3. Technically, there is another problem with the green top Jeff collected. What is it?
