A

bed rest if fetal presenting part high in pelvis & amniotic fluid is ruptured

66
Q

if umbilical cord is felt during vaginal exam, what do you do

A

keep gloved fingers in vagina to relieve pressure & position for gravity to help relieve compression (knees to chest or trendelenburg) -> apply O2 mask & prepare for C section

can use vacuum or forceps assessed vaginal birth but best practice is C section

before labor begins

72
Q

if cleared for vaginal delivery with a macrosomia baby, what should the nurse be prepared for

retention of placenta beyond 30 mins after birth, bleeding can be excessive & may require manual removal of placenta -> possible transfusion after depending on blood loss
increased risk for infection

77
