Agriculture is changing the environment. With increased populations, there is a greater demand for food. Which of the following

dusya [7]

The answer is D) desertification and deforestation

To know the answer you can rule out the non-possibilities. A is not correct because farmers use them all the time. B is not correct because water and pesticides can flow downstream and carry and deposit sediment. C is not correct because farmers can flood their own farms. When they plant things and a food comes, all of those plants will die or their roots will detach which lowers the food that can be sold. D is correct because farmers don't farm in the desert or the forest, so it would not be an impact of farming.

Diagnose: Mrs. Harris is a 60 year old white woman. She has noticed in recent years that her height has slightly decreased. Rece

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.

You are treating a short of breath 9-year-old male with a history of asthma. on scene he presents in severe respiratory distress

Temka [501]

The answer to this question would be: Heart rate 88

Respiratory distress in asthma patient can be dangerous. It won't only affect the respiratory system but also cardiovascular system. In asthma, the expiration phase is longer and harder because of the obstruction. This will cause lower amount of oxygen gain and lower amount of carbon dioxide dumped. The right ventricle also needs extra force since the lungs pressure is increased. The heart rate should be increased in this case to compensate the lower oxygen level.

Heart rate 88 is normal, not increased. This is a sign that the heart is already tired and might go arrest.
