If shoulder dystocia occurs during a delivery, the nurse should immediately

C
The McRoberts maneuver involves applying suprapubic pressure in an oblique or lateral approach to straighten the sacrum, allowing the anterior shoulder to dislodge. It requires maternal position changes in which the client's legs are bent at the knees and hyperflexed against her abdomen. Turning the client to the left side and administering oxygen is performed in the presence of non-reassuring FHR patterns. While preparing for a cesarean section delivery may be an outcome from shoulder dystocia, it is not the priority nursing intervention.
