Which term corresponds to the position that reduces vena cava compression in pregnancy?

• A. Left Lateral Recumbent Position
• B. Right Lateral Recumbent Position
• C. Supine Position
• D. Fowler's Position

Answer: (A)

When the pregnant uterus grows large, lying on the back can press on the inferior vena cava and reduce blood return to the heart, risking low blood pressure and poorer placental perfusion. The left lateral recumbent position best relieves this by shifting the uterus away from the IVC, which is located on the right side of the spine. With the uterus off the vessel, venous return increases, preload improves, and both maternal stability and fetal perfusion are better maintained.

The other positions don’t relieve the compression as effectively: the supine position worsens the pressure on the IVC, while the right lateral recumbent position helps less than the left. Fowler's position places you more upright and does not specifically address IVC compression.
