Answer:
This is why Killer T-cells are also called Cytotoxic T-cells. The pieces of destroyed cells and viruses are then cleaned up by macrophages. The other type of T-cell is the Helper T-cell. When a T-cell finds its virus match in your body, it makes many copies of itself to attack that virus.
Answer:
The thyroid gland absorbs almost all of the iodine in the body. When radioactive iodine (RAI), also known as I-131, is given to the body as a liquid or capsule, it becomes concentrated in thyroid cells. Radiation can kill the thyroid gland and any other thyroid cells or tissues (including cancer cells) that absorb iodine, without damaging any other organs.
Explanation:
The thyroid gland is an organ that belongs to the endocrine system and its function is to synthesize hormones that are responsible for controlling the body's metabolism, this gland has an important characteristic and that is that the hormones it produces have a unique chemical composition due to They are the only hormones that contain iodine in their structure, this in turn is essential for its functioning because the body does not synthesize it and it must be consumed in the diet. When a small dose of the radiopharmaceutical iodine 131 (Sodium Iodide 131I) is consumed, it is absorbed into the bloodstream and concentrated by the thyroid gland, where it begins to destroy cancer cells in the gland. 131I quickly attaches itself to thyroid cells to destroy them, but continues to emit radioactivity for a long time: it takes 8 days to halve. The beta radiation particles of 131I, which we call radioiodine or radioactive iodine, have a range of 2mm and act for a long time in a constant way. Fortunately, the body's metabolism quickly expels iodine through the urine, so that in one day the amount of iodine has decreased considerably.
Errors can happen in any profession but negligence can always be avoided.
The question looks incomplete as the options are missing. I hope you must be referring to this below mentioned question.
The nurse is caring for a client diagnosed with a hemorrhagic stroke. The nurse recognizes that which intervention is most important?
1). Monitoring for seizure activity
2).Maintaining a patent airway
3).Elevating the head of the bed to 30 degrees
4).Administering a stool softener
During the care of the client diagnosed with a hemorrhagic stroke, the nurse should prioritize the maintenance of the patient's airway as the most important intervention.
The main nursing intervention is maintaining the airway. A hemorrhagic stroke can result in immediate consequences such as cerebral hypoxia, decreased cerebral blood flow, and damage extension. Cerebral hypoxia is reduced by ensuring that the blood in the brain is adequately oxygenated. Blood flow to the tissues is necessary for proper brain function. Tissue oxygenation can be kept up by giving out extra oxygen and keeping hemoglobin and hematocrit within acceptable ranges.
The airway takes precedence over all other procedures, which are all appropriate. This should be managed to avoid any possible chance of aspiration. The client should be watched closely due to the possibility of seizures, and stool softeners are advised to avoid constipation and straining, although these are not the most crucial measures.
