Answer:
Option 2, Injection into a large muscle with the use of the Z-track method
Explanation:
The z-track method is used for parenteral iron preparations to avoid tissues from staining and irritation over the air lock method. Z track method prevents the leakage of medicine beneath the skin. In this method, after injecting the medicine the muscle and skin is pulled first and the injection is pulled later. This forms zigzag line that prevents medicine from leaking. Generally injected at thighs and buttocks
Hence, option 2 is correct
Hello! Allow me to help!
Your question: Can the atmosphere change in its composition?
My answer: Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.
Why is my answer correct? Good question! Allow me to explain: Tropical deforestation not only has a large impact on the carbon cycle and climate, but also affects the chemistry of the atmosphere. Together with the carbon cycle and weather patterns land use can affect the concentrations of greenhouse gases like methane and ozone.
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.
