A: Documenting the findings as normal is incorrect as a boggy and enlarged uterus is not a normal finding postpartum. B: Continuing to administer uterotonic medication without addressing the boggy uterus can lead to ineffective contraction. D: Administering an analgesic for pain does not address the underlying issue of uterine atony.
