According to the Friedman classification, a protracted latent phase in a NULLIPAROUS woman is diagnosed when the latent phase exceeds:
- A 12 hours
- B 14 hours
- C 20 hours ✓
- D 24 hours
Correct answer: C. 20 hours
Explanation
Friedman defined protracted latent phase as more than 20 hours in a nullipara and more than 14 hours in a multipara. The 14-hour figure is the best distractor because it is correct for multiparous women, so examinees who remember the number but forget the parity split will choose it. Therapeutic rest and, if indicated, oxytocin augmentation are the accepted approaches once maternal and fetal status are reassuring.
