Which position is correct for late-pregnancy transport to minimize vena cava compression?

• A. Semi-Fowler's
• B. Right lateral recumbent position
• C. Left lateral recumbent position
• D. Prone

Answer: (C)

Relieving vena cava compression is essential in late-pregnancy transport because the enlarged uterus can press on the inferior vena cava when a mother lies on her back, reducing venous return to the heart and risking maternal hypotension and fetal distress.

The left lateral recumbent position shifts the uterus off the major veins and uses gravity to maximize venous return, improving both cardiac output and placental perfusion during transport. This makes it the most effective position for minimizing aortocaval compression.

Other positions don’t address the compression as effectively. Semi-Fowler's elevates the upper body but doesn’t relieve pressure on the IVC. Right lateral recumbent is less effective because the IVC is on the right side, so this position doesn’t relieve the compression as well as the left side. Prone positioning would worsen venous return and isn’t practical for a late-pregnancy patient.
