Answer:

Mass of main sequence star - 10 to 200 times of mass of sun

Temperature of main sequence star - 15-18 million kelvin

Explanation:

Majority of stars in the universe are main sequence stars. These stars consists of helium in their cores. Mass of main sequence stars can be as low as one tenth of mass of sun and can be as high as 150 to 200 times the mass of sun. The age of a star depends on its mass. Thus more massive a star is more is its life. The temperature of star is high enough to fuse the hydrogen with in them to form helium atom. Their temperature can be as high as 15-18 million kelvin.

About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. All main sequence stars (including the Sun) are powered by the fusion of hydrogen (H) into helium (He). Fusion of hydrogen requires temperatures of more than 10 million Kelvin.

The registered nurse is overseeing a nursing student who is providing a dressing change to a patient who had a cesarean section.

natulia [17]

The nurse conducting wound care should choose a dressing that keeps the periwound skin dry and the surgical wound bed moist to contribute healing. The dressing used for wound care should control exudate from the wound, but it should not desiccate the wound bed. There must be a pressure in application while cleaning the periwound and wound may deepend the wound bed. Using sterile normal saline and a sterile gauze to clean the surgical wound reduces the incidences of infection.
