Final answer:
Pregnant women in the antepartum stage should avoid C) lifting heavy objects and d) prolonged standing to reduce the risk of preterm labor and injury. They should also maintain proper nutrition and engage in adequate physical activity, while avoiding exposure to harmful substances.
Step-by-step explanation:
During the antepartum stage, pregnant women should avoid certain activities that can increase the risk of preterm labor or injury. While adequate physical activity and maintaining proper nutrition are beneficial, there are specific actions that may pose risks such as lifting heavy objects and avoiding prolonged standing. Lifting heavy objects can cause back strain or injury and increase the risk of preterm labor. Prolonged standing can also lead to increased pressure on the cervix, potentially leading to preterm labor.
It is important for pregnant women to carefully monitor their physical activities and to adhere to guidelines provided by their healthcare professional. In addition to avoiding heavy lifting and prolonged standing, pregnant women should also avoid exposure to harmful substances like alcohol, illegal drugs, and certain medications, especially during the first eight weeks of pregnancy when major organs are forming.
