Which position should be avoided by pregnant clients in the third trimester?

In the third trimester of pregnancy, lying on the back is typically advised against due to the risk of compressing the inferior vena cava, a major vein that carries blood back to the heart. When this vein becomes compressed, it can reduce blood flow to the baby and may cause symptoms like dizziness, shortness of breath, and reduced circulation. As the uterus grows larger, positioning the pregnant client on her back can lead to discomfort and complications during exercise or rest.

While sitting with legs crossed and standing for long periods can have their challenges, they do not present the same level of risk as back lying does in this stage of pregnancy. Walking on uneven surfaces is generally safe, provided the pregnant individual is cautious about balance and stability. Therefore, avoiding back lying is essential to ensure the safety and comfort of the client and to promote healthy circulation for both mother and baby during the later stages of pregnancy.
