Question

The phlebotomist performed a syringe draw using a 23-gauge needle for a CBC and electrolytes on a chemotherapy patient whose veins are very fragile. She transferred them into the appropriate tubes using a blood transfer device. The MLS told the phlebotomist that she needed to redraw the electrolytes because the specimen was hemolyzed. The cause of hemolysis is most likely due to:

a) The patient's age
b) The use of a blood transfer device
c) The choice of needle gauge
d) The patient's chemotherapy treatment

Answer 1

Hemolysis in the blood sample is most likely due to the use of a blood transfer device.

Step-by-step explanation:

The cause of hemolysis in the patient's blood sample is most likely due to the use of a blood transfer device. Blood transfer devices are commonly used in phlebotomy to transfer blood from syringes to collection tubes. However, if the device is not properly used or if there is excessive agitation during the transfer process, it can cause hemolysis, which is the breakdown of red blood cells and release of hemoglobin into the plasma. This can result in inaccurate electrolyte measurements.
