While reviewing a chart, a notation of 4 edema in the left leg is noted. you would expect to see: select one:

a. mild pitting, no perceptible swelling of the leg.
b. moderate pitting, indentation subsides rapidly
c. deep pitting, leg is swollen
d. very deep pitting, indentation lasting 2-5 minutes.

The correct answer will be option-D

Explanation:

The biological Edema refers to the swelling of any portion of the body which could be small or large. The swelling is caused when the fluid from the blood vessel is leaked to the nearby tissue which causes the redness also.

Edema is assessed by measuring the depth of the pit formed by swelling in which 4+ edema shows that the edema is very deep pitted (6-8mm) which could last for 2-5 minutes.

Thus, option-D is the correct answer.

the answer is :

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
