According to the supplied material, when is forceps delivery considered to have failed?

The lecture defines failed forceps as no observable progress in descent after **three traction attempts**, assuming proper protocols have been followed. Failure should prompt reassessment rather than repeated forceful attempts. The other options are not the definition given in the material.\n\n**Key takeaway:** Lack of descent after three properly conducted traction attempts is a stopping point in the supplied definition.\n\n**Glossary:** **Descent**: Downward movement of the presenting part through the pelvis; **traction attempt**: A controlled application of pulling force during an effort or contraction.
