Final answer:
The pregnancy-related condition that increases the risk for shoulder dystocia is 4) Polyhydramnios.
Step-by-step explanation:
Polyhydramnios refers to an excess accumulation of amniotic fluid during pregnancy. This condition can increase the risk of shoulder dystocia, which is when the baby's shoulder gets stuck behind the mother's pelvic bone during delivery. The excessive fluid makes it more difficult for the baby to pass through the birth canal, leading to this complication.
It is important for healthcare providers to monitor and manage polyhydramnios to minimize the risk of shoulder dystocia and ensure a safe delivery. Therefore polyhydramnios is the pregnancy-related condition that increases the risk for shoulder dystocia. The correct answer is 4) Polyhydramnios.
