The nurse instructs a pregnant woman in labor that she must avoid lying on her back. the nurse bases this instruction on the information that the supine position is primarily avoided because it can do what?

The supine position - lying on your back - is the traditional method of giving birth that is so often depicted in movies. This position, however, has many detrimental effects and is often not advisable for pregnant women in labor. The position can lead to longer labor, which puts stress on the baby. It makes contractions more painful and less effective, which is what extends the time of labor. It also reduces flow of blood and oxygen to the baby, which is not safe. Additionally, it increases the risk of tearing. Anatomically, it is not the best position because it causes one to be pushing the baby up instead of down and it causes the birth canal to narrow.
