Q

What are some of the premonitory signs of labor (physiologic signs that precede labor)?

A
  • Backache
  • Weight loss (1-3 lbs)
  • Lightening
  • Contractions

  • Energy burst (nesting)
  • ROM
2
Q

Labor usually occurs within _____ of the ROM

24 hours

3
Q

What can prolonged ROM greater than 24 hours before delivery of a fetus lead to?

Q

Why should a nurse assess FHR immediately following the ROM?
