Step-by-step explanation:
Three priority nursing actions in the post delivery period for the client with preeclampsia include monitoring for signs of worsening preeclampsia, managing hypertension, and preventing seizures. Firstly, nurses must meticulously monitor vital signs, particularly blood pressure, as hypertension can worsen post delivery. Secondly, administering magnesium sulfate as ordered can help prevent seizures, which is a primary concern with preeclampsia. Lastly, it is essential to observe for signs of postpartum hemorrhage, as clients with preeclampsia may be at increased risk. This includes checking uterine firmness and monitoring for excessive lochia.
