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.

Answer: This view fits best with "THE PRAGMATIC THEORY OF TRUTH".
Explanation: The pragmatic theory of truth states that something or a statement can be true, if only it have been tested and practice to be true. It means that truth can only be verified by experimenting ones belief or concept.
For science to use electron which is believed doesn't physically exist to explain concept that physically exist, that means the truth of the existence of an electron has has been tested and has gone through practicals, which shows that electron exist. The pragmatic theory of truth proves the existence of an electron to be true because it has been proven and tested to be true, using some physical principle, even though it has not been physically seen. Many scientific theories uses pragmatic theory of truth, to stand it's statement to be truth.
The client should be helped to sit at the edge of the bed while leaning forward and supporting their arms on a bedside table, a pillow, or a folded towel since a needle will be put into the intercostal area during a thoracentesis.
<h3>Which of the following observations demonstrates that the patient is having respiratory problems?</h3>
Observe the depth of breathing and make a note of whether it is shallow or deep. Breathing difficulties can be detected by symptoms such pursed-lip breathing, nasal flaring, audible breathing, intercostal retractions, anxiousness, and the usage of auxiliary muscles.
A significant air leak between the drain and the patient is indicated by the chamber's persistent bubbling. Examine the drain for disconnections, dislodgments, and loose connections while evaluating the patient's condition. If the issue cannot be fixed, notify medical personnel right away.
