Answer:
a pulmonary embolism.

A sudden onset of difficulty breathing, sharp chest pain and cyanosis that persists despite supplemental oxygen is most consistent with<u> a pulmonary embolism.</u>
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:
1.5mL
Explanation:
This is 10mg/2mL, which simplifies to 5mg/1mL. To get 7.5mg, you need 1.5mL (multiple numerator and denominator by 1.5).
The nurse should be with the client that is suggesting taking the drug with food. When the client reported experiencing nausea, anorexia, and abdominal pain after starting trimethoprim and sulfamethoxazole for urinary tract infections.
What is a urinary tract infection?
Urinary tract infection is a condition when the organs belonging to the urinary system become infected. These organs can be the kidneys, ureters, urethra, or bladder. However, urinary tract infections generally occur in the urethra and bladder.
Starting from the kidneys, residual substances in the blood are filtered and excreted in the form of urine. Next, urine flows from the kidneys through the ureters to the bladder. Once stored in the bladder, urine will be expelled out of the body through a tube called the urethra.
