You just received a requisition to collect blood from Mrs. Johnson in Room 318. Upon palpating Mrs. Johnson’s veins, you have determined she has small, fragile veins. You decided the best method for drawing her blood would be with a syringe and a butterfly needle. Upon checking the requisition you see the following tubes are required to complete the order. They are: Light-blue-topped tube, Lavender-topped tube, and Green-topped tube. In what order would you transfer the blood from the syringe using a transfer device into the evacuated tubes?

A requisition for a blood draw on Mr. Al K. Seltzer in Room 555 was just given to you. After surveying Mr. Seltzer’s arms and hands, you have determined his veins are too small and fragile for a venipuncture. However, upon checking the requisition you see the following tests to be collected: CBC, Lipids, and STAT Glucose. So you have decided the best method to use to collect Mr. Seltzer’s blood is to do a capillary/dermal puncture. What tubes would you select for the draw and in what order would you fill them?
Lavender-topped tube, Gold (SST) tube, and Light-green-topped tube.
Gold (SST) tube, Lavender-topped tube, and Light-green-topped tube.

Because a blood culture requires a sterile environment be created at the puncture site, which of the following should be used to clean the puncture site prior to venipuncture?
Soap and water
Diluted bleach
Betadine, iodine, or chlorhexidine
Cleaning is not necessary because the skin is naturally free of bacteria
Betadine, iodine, or chlorhexidine
What should the phlebotomist use to create a pressure bandage on a patient with fragile skin such as a young child or the elderly after a venipuncture?
Gauze pad and adhesive tape.
An adhesive bandage.
No bandage is necessary because bleeding will stop immediately after needle withdrawal.
Gauze pad covered with either roller gauze or Coban is wrapped entirely around the arm so tape is not placed on the skin.

When performing a dermal puncture, if the patient’s fingers or the heel feel cool to the touch, what should the phlebotomist do to help increase blood flow to the site?
Use a warm towel, cloth or heel warmer packet to warm the site.
Squeeze or massage the finger or heel for 30 seconds.
Use a lancet with a puncture depth of 2.5 mm.
Apply an ice pack to the puncture site for at least 15 seconds.
Use a warm towel, cloth or heel warmer packet to warm the site.
The phlebotomist has three venipunctures left to perform toward the end of his/her shift. The phlebotomist realizes that he/she has only one tourniquet left, and that the time it would take for him/her to get more would make him/her late for an after-work appointment. What should the phlebotomist do?
Use the same tourniquet on all three patients without cleaning.
Clean the tourniquet between each patient and use it on all three patients.
Throw the tourniquet away after use on the first patient and secure additional tourniquets for the remaining patients.
Tie the fingers of a glove around the patient’s arm creating a tourniquet.
Throw the tourniquet away after use on the first patient and secure additional tourniquets for the remaining patients.
