When caring for a cardiac client in labor, what position should the woman be placed in?

For a cardiac client in labor, placing the woman in the left lateral and semi-Fowler's position is beneficial for several reasons. This position enhances venous return by relieving pressure on the inferior vena cava, which can be compromised in the supine position, especially in pregnant women. By lying on her left side, the client also improves uteroplacental perfusion and maximizes oxygen delivery to both the mother and the fetus.

The semi-Fowler's aspect allows for an elevated upper body, which can help manage the client's comfort and reduce the risk of respiratory distress, common in patients with cardiac issues. Additionally, this position can alleviate pressure on the diaphragm, making breathing easier during labor.

Other positions, such as supine or prone, may exacerbate complications in cardiac clients by either compressing major blood vessels or hindering effective breathing. The right lateral position, while providing some relief, does not offer the same advantages for venous return and uteroplacental circulation as the left lateral and semi-Fowler's combined position.
