Final answer:
For a postpartum client with a boggy uterus, the immediate nursing action is to perform a fundal massage to help the uterus contract and to prevent postpartum hemorrhage. Further assessment and notifying healthcare providers are also critical steps.
Step-by-step explanation:
The immediate nursing action for a postpartum client with a boggy uterus that is displaced above and to the right of the umbilicus is c. Perform fundal massage. This action helps the uterus contract and expel any remaining clots or placental fragments, which is crucial since retained placenta can lead to postpartum hemorrhage. This action complements the body's natural process of involution, which is aided by the hormone oxytocin released during breastfeeding and labor.
After performing fundal massage, it is essential to assess for any signs of postpartum hemorrhage and other complications, such as shock, and simultaneously notify the healthcare provider. Administration of oxytocin may be indicated if the uterus does not respond to massage alone, but this should be done following a physician's order. The nurse should also ensure that the client's bladder is empty to help the uterus contract more effectively.
