A

progress of fetus through maternal pelvis (+ or -, in relation to location of presenting part of fetus to ischial spine)

121
Q

Phases of labor

A

4 stages (labor, baby, placenta, recovery)

122
Q

1st stage of labor

A

onset of labor to complete cervical dilation

  • latent phase
  • active phase
  • transition phase
123
Q

latent phase

A

occurs in 1st stage of labor, labor onset to 3 cm dilation

124
Q

active phase

A

occurs in the 1st stage of labor, 4-7 cm dilation

125
Q

transition phase

A

occurs in the 1st stage of labor, 8-10 cm dilated

126
Q

2nd stage of labor

A

complete dilation (10 cm) to birth of baby, have urge to push, increase of bloody show, if ROM hasn’t happened you will have AROM

127
Q

3rd stage of labor

A

birth to placental expulsion

128
Q

4th stage of labor

A

1-4 hours after placental expulsion, uterus contracts to control bleeding at placental site

129
Q

occurs when widest part of babies head is completely encircled by vagina (ring)

130
Q

characteristics of transition

A

increase bloody show, increase anxiety, hyperventilation, increase sensitivity to touch, leg cramps, low back ache, inward focus, increase rectal pressure

131
Q

movement of presenting part through pelvis, measured by stations

132
Q

why does flexion of the head happen during delivery

A

decrease the diameter of babies head

133
Q

babies head rotates into position

A

internal rotation

134
Q

turns back to initial position

A

restitution

135
Q

after presenting part goes through symphis pubis head comes out, face towards rectum

136
Q

delivery of shoulders

A

external rotation

137
Q

cardinal movements in order

A

descent, flexion, internal rotation, extension, restitution, external rotation, expulsion

138
Q
