Final answer:
If a pregnant client in the 2nd trimester is suspected to have abruptio placentae, the nurse would expect to note uterine tenderness or pain, which is the correct answer among the provided options.
Step-by-step explanation:
A nurse assessing a pregnant client in the 2nd trimester with a suspected diagnosis of abruptio placentae would likely expect to note the presence of uterine tenderness or pain. Abruptio placentae, also known as placental abruption, is a condition where the placental lining has separated from the uterus of the mother before delivery. This condition can lead to significant complications and is one of the causes of postpartum hemorrhage if not managed properly. Unlike placenta previa, which can present with painless, bright red vaginal bleeding, abruptio placentae typically involves abdominal pain and uterine tenderness. Option 3 is the expected finding associated with abruptio placentae.
After the delivery of the newborn, it is important for the obstetrician to examine and ensure the expelled placenta and fetal membranes are intact to prevent postpartum hemorrhage. Additionally, the mother's body goes through a process of involution, returning the uterus and abdominal organs to their pre-pregnancy state, assisted by breastfeeding which facilitates uterine contractions.
