Final answer:
In cases of cord presentation, positioning the pregnant woman in the knee-chest or Trendelenburg position is recommended to alleviate pressure on the cord and prevent fetal oxygen deprivation, often leading to an emergency Caesarian section.
Step-by-step explanation:
In the scenario of a cord presentation, where the umbilical cord precedes the fetus during birth, repositioning the mother is critical. The recommended position for a pregnant woman with a cord presentation is the knee-chest position or a Trendelenburg position with the hips elevated. This reduces the risk of compression of the cord, which could compromise fetal oxygen supply. In such a case, immediate medical attention is needed, and the situation may necessitate a Caesarian section to safely deliver the baby.
