Final answer:
The Kleihauer-Betke test is prescribed to determine if there is maternal-fetal hemorrhage following suspected placental abruption, by identifying fetal blood cells in the maternal blood.
Step-by-step explanation:
The nurse should expect the provider to prescribe a Kleihauer-Betke test for a client who has suspected placental abruption to determine if there is maternal-fetal hemorrhage. This test is used to assess the presence of fetal blood in the maternal circulation, which can occur when there is a breach in the placental barrier, as in the case of placental abruption. When the placenta detaches from the uterine wall, there can be an exchange of blood between the mother and the fetus.
Identifying fetal blood cells in the maternal blood can help diagnose the extent of hemorrhage, which may affect the management of the pregnancy and delivery. It's also essential for the obstetrician to examine the expelled placenta and fetal membranes rigorously to ensure no fragments remain, as this can cause postpartum complications like hemorrhage. Intact membranes and proper contraction of the uterus also help facilitate the mother's abdominal organs returning to their pre-pregnancy locations.
