- A. perform a cesarean section
- B. assist with vacuum extraction
- C. perform an emergency cesarean
- D. assist with forceps delivery
Correct Answer: B
Rationale: The correct answer is B: assist with vacuum extraction. This intervention is appropriate when prolonged pushing has not resulted in progress during labor.

Performing a cesarean section (choices A and C) would be considered if vacuum extraction is unsuccessful or contraindicated due to specific factors. Forceps delivery (choice D) is another option but is generally considered more invasive and carries higher risks compared to vacuum extraction.
