someon at 39 weeks and not progressing
What should you do in the even of fetal distress?
prep client for emergency c-section
Risks for preterm labor
- infection
- gestational diabetes
- uterine fibroids
- medications
What is a premature rupture of membranes>
ruptured earlier than the end of 37th week. Greater risk if before 34th week.
Cold stress causes oxygen consumption and energy to be diverted from maintaining normal brain cell function and cardiac functinon, what is the result?
- metabolic and physiologic
Characteristics of placenta previa
- painless
- brigh red vaginal bleeding
- uterus is soft/relaxed/nontender
What is the fibronectin test?
positive means onset of labor in 1 to 3 weeks
What is a normal contraction frequency?
no more frequen than 1-1/2 min
What is the first line of defense for an obstetric emergency
cardiopulmonary resuscitation
What part do you suction first mouth or nose?
mouth
Circumcision Care
- Vitamin K prior
- feeding witheld 2-4 hrs
- bulb syringe ready
- Petroleum jelly over the site to prevent diaper from sticking
- diaper attached loosely
What actions should you take if the membranes have ruptured
- assess the FHR b/c of risk of collapsed umbiical cord
- asses the color of the amniotic fluid b/c meconium stained fluid can indicate fetal stress.
Describe Colostrum
- high in protein, low in carbs/fat
- rich in IgA- protects GI
- helps normal flora
- speeds passage of meconium (laxative effect)
What can happen with oligohydramnios
- ruptured membranes
- placental insufficiency
- SGA
- limited oxygen
What is a precipitous labor/birth
labor and delivery after an unusually short amount of time
What is the fern test
determines the presence of amniotic fluid leakage. Produces a fernlike pattern b/c of salts
What can substance abuse do to the fetus
risk for fetal growth restriction, abruptio placentae, and fetal bradycardia
Nursing interventions for tachysystole?
- reduce oxytocin
- increase infusion
- lateral position
- give oxygen
- notify physican
What could be indications for bradycardia?
- fetal head compression
- umbilical cord compression
What candidate would not be good for a VBAC
if she had a vertical incision
Why does a newbor recieve erythromycin?
Opthalmia Neotorium
Proper communication for a woman experiencing grief and loss
be specific with care, don’t ask why, or “is everything okay”
