Final answer:
The first nursing action is to ensure the expelled placenta and fetal membranes are intact. Assess the bladder and assist with voiding if necessary.
Step-by-step explanation:
The first nursing action when a mom requests to void postpartum is to ensure that the expelled placenta and fetal membranes are intact. This is important because if fragments of the placenta remain in the uterus, they can lead to postpartum hemorrhage. The obstetrician should examine these tissues to rule out any complications.
Additionally, it is crucial to assess the mother's bladder for distention. A full bladder can prevent the uterus from contracting properly and may impede the process of involution. If the bladder is full, the nurse should assist the mom in voiding to relieve pressure and promote uterine contractions.
In summary, the first nursing action for a mom requesting to void postpartum is to ensure that the expelled placenta and fetal membranes are intact. Simultaneously, the nurse should assess the mother's bladder and assist with voiding if needed to prevent complications and facilitate the process of involution.
