Final answer:
The priority when caring for a woman with severe preeclampsia is to promote placental blood flow, prevent maternal injury, and maintain the ordered rate of anticonvulsant medications. Blood pressure should be carefully managed, but not abruptly reduced to pre-pregnancy levels.
Step-by-step explanation:
When providing intrapartum care for a woman with severe preeclampsia, the priority of nursing care is to promote placental blood flow and prevent maternal injury. This involves careful monitoring and management to avoid complications such as eclampsia, which can lead to seizures. Maintaining the ordered rate of anticonvulsant medications is crucial to preventing seizures, while monitoring intravenous fluids and observation of the urine output ensures proper renal function and helps prevent further complications.
Blood pressure management is also critical; however, it should not be reduced to pre-pregnancy levels abruptly as it could lead to placental underperfusion and fetal distress. Instead, blood pressure should be lowered gradually and carefully to safe levels. Moreover, the overall systemic changes that include an increase in blood volume and changes in circulatory and respiratory systems should be taken into account when managing preeclampsia.
