I was the charge nurse then. I have just started on my 24-hour check on patients’ charts when the Pulmo Fellow came in to review one of her consultant’s patient’s chart. The patient is an 83-year old female who I learned has been coming in and out of the hospital due to her heart condition. This time she was admitted due to melena which is passage of black, tarry stools composed largely of blood that has been acted on by gastric juices, indicative of bleeding in the upper digestive tract (answers.com). Her test on occult blood came in positive and we have been wondering why she has not been referred to a gastroenterologist. The fellow asked me if the said patient has already referral to a said specialist to which I replied back, she might want to order for a referral. She said it is not her decision to make. A couple of days have passed and the patient still continues to pass melena and finally the attending has referred her to a gastroenterologist.
After the gut specialist has seen the patient, he ordered for an RBC tagging. What I like about being stationed at the Medical-Surgical ward is you got a broad horizon of must-learns. I googled for its 411 before I get to be asked by the relatives or the nurse supervisor on duty.
What is nice about our institution is that they have this internet surfing time to allow for the nurses to search on some medical information.
According to Medline Plus, RBC (red blood cell) tagging or an RBC nuclear scan is a group of tests using small amounts of radioactive material to mark (tag) red blood cells (RBCs). The body is then scanned to detect the location and flow of the tagged RBCs.
The RBCs are tagged with radioisotope in 1 of 2 ways.
The first method involves removing blood from a vein. The red blood cells are separated from the rest of the blood sample and then mixed with the radioactive material. The cells with the radioactive material are considered “tagged.” A short time later the tagged RBCs are injected into one of your veins.
The second method involves an injection of medicine that will allow the radioactive material to attach to your red blood cells. The radioactive material is injected into a vein 15 or 20 minutes after you receive this medicine.
Scanning may be done immediately or after a delay. You will lie on a table underneath a special camera that detects the location and amount of radiation given off by the tagged cells.
A series of scans may be performed. The specific areas scanned depend on the reason for the test.
And true to my hunch, the NSOD asked me about the RBC tagging when she rounded our unit.
I hope that this test will determine the source of bleeding.
