Vaginal examination of a client in labor reveals the fetus's larger, diamond-shaped fontanel is toward the anterior portion of the client's pelvis. the nurse interprets this finding as indicative of what situation?

The correct answer is that "the client may need interventions to ease back pain and change fetal position".
According to the nurse's finding, the fetal position is occupit posterior, meaning that the back of the baby's head is against the mother's back. This is a position that can cause severe back pain during labour since pressure is applied to the mother's back. The baby needs to turn to occupit anterior position and in order to do so, the mother needs to lie on her side. This intervention will help the rotation of the baby, easing the mother's back pain and facilitating delivery.
