Hematoma is an open injury that occurs whenever a large blood vessel is damaged and bleeds rapidly. TrueFalse You should never remove an avulsion skin flap, regardless of its size. TrueFalse When possible, ALS providers should administer IV fluid within 3 minutes after the crushing object is lifted off the body.

1. Hematoma is an open injury that occurs whenever a large blood vessel is damaged and bleeds rapidly. False

2. You should never remove an avulsion skin flap, regardless of its size. True

3. When possible, ALS providers should administer IV fluid within 3 minutes after the crushing object is lifted off the body. False

Explanation:

1. It is false because, although is true that a hematoma occurs when you have a large blood vessel damaged, i t is a closed injury, not an open one.

2. It is true, you should never remove an avulsion skin flap, regardless of its size. The avulsion may have a serious infection.

3. It is false  because ALS providers should administer IV fluid before the crushing object is lifted off the body.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
