Which statement regarding the McRoberts and suprapubic pressure maneuvers is incorrect?

The statement regarding McRoberts and suprapubic pressure maneuvers that is incorrect is that they are considered primary maneuvers because of their proven superiority over other maneuvers. While McRoberts and suprapubic pressure are indeed effective in managing shoulder dystocia and are commonly used as first-line interventions, the designation as "primary maneuvers" does not imply they are categorically superior to all other methods in every situation. Instead, these maneuvers are among several recommended techniques that can be employed based on the specific circumstances of each case.

In practice, the combination of different approaches may be necessary depending on the individual clinical scenario, the presentation of the dystocia, and the experience of the healthcare provider. Therefore, categorizing them as superior may misrepresent the complexity of shoulder dystocia management, where adaptability and multimodal strategies are crucial.

The other statements are accurate: McRoberts and suprapubic pressure can indeed be performed rapidly, they have been shown to resolve shoulder dystocia in a significant percentage of cases within a short time frame, and the major risks involve injuries to surrounding structures like nerves and the symphysis pubis.
