Chronic backache
<span>The nurse should provide preventive measures for chronic backache as a consequence of lordosis when caring for this client. Chloasma is characterized by darkened areas on the face, particularly over the nose and cheeks. It is also known as the mark of pregnancy. Chloasma is not caused by lordosis. Diastasis occurs as the pregnancy progresses when the rectus muscle stretches to the point that it separates. It is not caused by lordosis. Edema in lower extremities occurs due to an impeded venous return caused by pressure of growing fetus on pelvic and femoral areas. It is not caused by lordosis.</span>
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. The next generation will have the things they will need to survive and the longer the generation goes the more fetchers they will have.
