An example of a toxic chemical used in some health-care institutions is _____.


a drug used to treat infections

a solution used to clean medical equipment

a radioactive substance used for treatment

all of the above

Answers

Answer 1
All of the above would be the correct answer. In fact, all of the substances listed illustrate the adage, “The dose makes the poison.” Take the first answer choice: Antibiotics are drugs used to treat bacterial infections. But many antibiotics have side effects, some of which can be quite dangerous—these antibiotics tend to be used only as a last resort. While most chemicals used to clean medical equipment probably would not be indicated for human use, there are a few examples: A very common example would be ethanol; ethanol is what makes alcoholic beverages intoxicating, but it is also an effective disinfectant used in medical settings at concentrations far greater than it is present in most drinks. The third answer choice is a clear example of a toxic substance one might find used in a medical setting. There is an entire class of radiopharmaceuticals, or drugs that comprise radioactive isotopes. An example of such a drug would be sodium iodide where a radioactive isotope of iodide is the anion. Iodine (in the form of iodide) in the body is taken up and concentrated in the thyroid gland. When one ingests a radioactive isotope of iodide, it is concentrated in the thyroid, where the unstable atom decays, emitting ionizing radiation that destroys cells. As such, this radiopharmaceutical is used to treat conditions where the cells in the thyroid need to be killed because their presence is pathological, such as in some instances of hyperthyroidism and thyroid cancer. The dosage of any radioactive drug must be very carefully determined and the medication handled and administered properly, as ionizing radiation is harmful to all cells.

When did the term stress enter scientific literature?

Answers

Answer: 1930s

The term stress as it relates to the human condition first emerged in scientific literature in the 1930s, but it did not enter the popular vernacular until the 1970s (Lyon, 2012).

Hope this helps :)

The term stress entered scientific literature in the 1930s.

The term was first used by Hans Selye, a Hungarian-Canadian endocrinologist, to describe the general adaptation syndrome, which is the body's response to stressors. The general adaptation syndrome is a three-stage process that includes alarm, resistance, and exhaustion. Selye's work on stress was groundbreaking, and it helped to pave the way for the field of stress research.

Today, stress is a well-studied phenomenon, and it is known to have a significant impact on physical and mental health. The alarm stage is the initial response to a stressor. The resistance stage is the second stage of the general adaptation syndrome.  The exhaustion stage is the final stage of the general adaptation syndrome. If the stressor is too severe or if the body is not able to adapt, the body will eventually reach a state of exhaustion.

What is obesity?

A condition characterized by abnormally high levels of body fat that raises the chance of developing serious health complications.

Intake of more calories than expenditure of calories through physical activity and daily activities is a common contributor to obesity. When a person's body mass index is thirty or more or higher, they are considered obese. The most obvious sign is an increased chance of developing major health issues due to the accumulation of excessive body fat.

Alterations to one's way of life, such as one's diet and level of physical activity, are the backbone of the treatment.

At least 2.8 million adults die each year as a result of being overweight or obese. 44% of the diabetes burden, 23% of the ischaemic heart disease burden and between 7% and 41% of certain cancer burdens are attributable to overweight and obesity.
