Q

Nursing Interventions for Late Decels

A

change position of mother, roll to left side
stop pitocin if being given
give 8-10L/min of O2
prep for delivery if not fixed

17
Q

Prolonged Decels Define

A

Anything that is lasting more than 2 min but less than 10 min.. fetal HR is +/-15 of baseline

18
Q

Conditions you MUST report

A
  • non-reassuring patterns
  • sever variable decels
  • late decels
  • severe bradycardia
  • fetal dysrhythmias
19
Q

Emergency Measures Inteventions for Late Decels

A

MAXIMIZE O2 FOR THE FETUS
reposition the mother to her side
give 8-10L/min via face mask
give fluids

20
Q

Biophysical Profle Management

A

Aim for a score of 10

21
Q

Amniocentesis

A

NOT FIRST CHOICE OPTION
used in early pregnancy for chromosomal testing
used in 3rd trimester to check for lung development

22
Q

Surfactant

A

produced by fetal lungs

needed to prevent collapse of alveoli

23
Q

Surfactant (made of what)

A

Lecithin and Sphingomyelin

24
Q

Treatment for lack of surfactant

A

Corticosteroids:

Dexamethasone/ betamethasone

25
Q

Phosphatidylglycerol Test

A

determines the maturity of the lungs
