During late pregnancy, which position relieves vena cava compression?

• A. Left Lateral Recumbent Position
• B. Right Lateral Recumbent Position
• C. Supine Position
• D. Sitting Up

Answer: (A)

When a woman is in late pregnancy, the enlarged uterus can press on the inferior vena cava (IVC) when she lies flat, reducing venous return to the heart and potentially lowering both maternal cardiac output and fetal oxygen delivery. Lying on the left side shifts the uterus away from the IVC, relieving this compression. This position improves venous return, stabilizes blood pressure, and enhances placental blood flow, which is why the left lateral recumbent position is the best choice. The supine position keeps the uterus pressing on the IVC, while sitting up or lying on the right side don’t relieve the compression as effectively.
