Final answer:
After 30 hours following the rupture of membranes in a client in labor, the nurse would most anticipate the risk of chorioamnionitis, an infection of the fetal membranes. Other conditions such as cord prolapse, abruptio placentae, or placenta previa are not as directly associated with prolonged membrane rupture.
Step-by-step explanation:
The condition the nurse would most anticipate for a client who is in labor 30 hours after her membranes ruptured is chorioamnionitis. Chorioamnionitis is an infection of the fetal membranes (amnion and chorion) due to a bacterial infection. This condition can occur when the membranes rupture and labor does not follow immediately after, providing an opportunity for bacteria to ascend into the uterine cavity and infect the membranes, amniotic fluid, and fetus.
Conditions like cord prolapse and abruptio placentae are severe but not primarily associated with prolonged membrane rupture. However, they can be complications of labor and delivery in other contexts. Placenta previa does not emerge as a result of membrane rupture but is instead a condition where the placenta covers the cervix and can lead to bleeding.
Therefore, with the prolonged rupture of membranes, the focus is on monitoring for signs of infection such as maternal fever, fetal tachycardia, tenderness in the uterus, and foul-smelling amniotic fluid, which would all be indicative of chorioamnionitis and should be treated immediately to reduce risks to both the mother and the baby.
