Final answer:
Massage the fundus until firm and in the midline position is the correct intervention for a postpartum woman with a boggy and deviated fundus; this can prevent postpartum hemorrhage due to uterine atony. Other actions such as pain medication, IV start, or notifying a healthcare provider may follow based on the woman's response.
Step-by-step explanation:
The appropriate nursing intervention for a postpartum woman whose fundus is boggy and deviated to the side is to massage the fundus until it is firm and in the midline position. This action is vital because a boggy uterus can indicate uterine atony, a condition in which the uterus has lost its tone and strength to contract effectively, potentially leading to postpartum hemorrhage. Following the massage, if the uterus does not become firm or if other symptoms are observed, it may be necessary to notify the healthcare provider for further assessment and possible medical interventions, such as administering uterotonics. Additionally, it is crucial to closely monitor the woman's vital signs and blood loss during this time. Administering pain medication, starting an IV line, or notifying the healthcare provider may be suitable actions, but they are not the initial steps to be taken when a fundus is found to be boggy and lateral.
