Q

5 P’s in childbirth

A

P = passenger (fetus & placenta)
P = passageway

A

uterine activity and contraction patterns

58
Q

passenger P consists of

  1. Fetal Presentation – what part is entering pelvis (head, breech, shoulder)
  2. Fetal Lie - relationship of spine to mom = transverse (sideways) or parallel*
  3. Fetal Attitude - relationship of fetus parts – flexion* or extension
  4. fetal position
59

Fetal Position is descirbed by

A
  1. naming the side the baby is facing–right (R) or left (L)
