Erin, the medical assistant, is asked to draw a CBC and electrolytes on a patient. While drawing the blood, she notices a hematoma forming and she still has one tube left to draw. Why would a hematoma develop when drawing blood? What should Erin do? Will a hematoma affect the lab results of either of these tests?
Homework Answers
Hematoma is a common complication during drawing of blood venipuncture. Hematoma occurs due to the injury to the blood vessel that is used for venipuncture. This causes sweeping of blood from the vein into the surrounding tissues leading to hematoma formation.
As soon as Erin notices hematoma, she should stop drawing blood from that area. Withdraw the needle and release the torniquet. Then apply pressure to the area for a few minutes.
Drawing of blood from the hematoma affected area can cause discomfort and pain to patient. It can also lead to poor quality of blood samples collected and can cause error in blood test results
