7
Q

Release of an egg

A

Is called an ovum

8
Q

At end of pregnancy the uterus and placenta prodcues

Butt first or limb first

  • flex knees of Mom
  • don’t pull, but let butt deliver
  • once legs are out, support body
  • lower newborn to hang legs so body weight pulls itself
  • grab legs when head is visible lift up and down of legs and head should exit easily
  • if no head after 3 minutes, newborn in danger of suffocation. Insert v shaped fingers of newborns nose and mouth pressing against the vaginal canal until head is delivered

Slip finger under and over fetus head

Cut if too tight

110
Q

Prolapsed Umbilical Cord

A

Cord emerges first before fetus

  • supine mom with hips elevated
  • 100% oxygen
  • pant with each contraction decreasing bearing down
  • push presenting part (not cord) back into vagina until no longer presses on cord
  • cover exposed portion of cord with dressings moistened in saline
  • maintain position and transport fast
111
Q

Uterine Inversion

A

Placenta fails to detach and adheres to uterine wall when expelled resulting in prolapsed uterus
-keep recumbent

-oxytocin to help hemmorage
Attempt once to push uterus easily back inside.
If this fails, cover portruding uterus with saline wet dressing

112
Q

Pregnant Trauma

A

If trauma occurs and Mom is bleeding, blood will shunt from fetus and be used for Mom.
When signs of shock present, fetal mortality is 70-80%
Normal fetal heart rate is 120-180
If transported supine, elevate right hip 6 inches, if not recumbant position is necessary or elevate backboard underneath
