What precaution should a pregnant client take while traveling by air during her second trimester?

Wearing support hose is an important precaution for a pregnant client traveling by air during her second trimester because it helps improve venous circulation, which can be compromised during long periods of sitting, such as on an airplane. Pregnancy increases the risk of developing varicose veins and deep vein thrombosis (DVT), especially when not moving for extended periods. Support hose apply gentle pressure on the legs, which aids in venous return and reduces the risk of swelling and discomfort.

While there are other precautions that can be taken, such as staying hydrated and changing positions frequently, wearing support hose is particularly effective in managing the physical changes and risks associated with travel during pregnancy. It addresses the specific issue of venous stasis that can occur during flights, making it a proactive measure to ensure the safety and comfort of the pregnant traveler.
