Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.
The Scenario:
A nursing assistant has entered a scene where a blood spill has occurred. After ensuring the patient is safe, the nursing assistant dresses in personal protective equipment, and removes the visible blood with an absorbent material. The nursing assistant then throws the blood-soaked material into the trash can.
What the nursing assistant did wrong:
The nursing assistant did not call the lead nurse to report the incident prior to cleaning.
Answer:
"Code Red" and "Code Blue" are both terms that are often used to refer to a cardiopulmonary arrest, but other types of emergencies (for example bomb threats, terrorist activity, child abductions, or mass casualties) may be given "Code" designations too. Colors, numbers, or other designations may follow a "Code" announcement to identify the type of emergency that is occurring.
