complete solutions rated A+
4 pelvic types - correct answer ✔✔-Gynecoid (round) --Android (heart)
-Platypelvic (flat) --Anthropoid (oval)
Suboccipitobregmatic (Vertex) - correct answer ✔✔Most common, smallest diameter, chin flexed to
chest. Occiput is presenting part.
Occipitofrontal (Sinciput/Military) - correct answer ✔✔Fetal head not flexed or extended, top of head is
presenting part.
Occipitomental (Brow): - correct answer ✔✔-Head partially extended, largest diameter. Sinciput is
presenting part.
Submentobregmatic (Face) - correct answer ✔✔Head hyperextended. Face is presenting part.
Engagement - correct answer ✔✔Occurs when the largest diameter of the presenting part reaches or
passes through the pelvic inlet and is at the level of the ischial spines
Fetal Station - correct answer ✔✔Relationship between the presenting part to an imaginary line
between the ischial spines of the maternal pelvis.
-5 = at the pelvic inlet
0 = engaged in pelvis
+5 = at the pelvic outlet
Fetal Position - correct answer ✔✔The relationship of the presenting part of the fetus with the 4
quadrants of the maternal pelvis.
-3 letter abbreviation includes:
, -1. Described as Right or Left side of pelvis (R or L)
-2. Specific presenting part
-3. Location of presenting part: anterior, posterior, or transverse
Contractions - correct answer ✔✔1.Frequency: The beginning of one contraction to the beginning of the
next.
2.Duration: Beginning of contraction to the end of the same contraction.
3.Intensity: Strength of the contraction.
3 Stages of Contraction - correct answer ✔✔1.Increment: The building up of the contraction
2.Acme: Peak of the contraction
3.Decrement: The letting up of the contraction.
Labor - correct answer ✔✔Rhythmic uterine contractions of enough frequency, intensity, and duration,
to effect cervical dilation and effacement and leads to fetal decent.
Dilation - correct answer ✔✔-The opening of the cervix. Documented in measurements of 0-10
centimeters
Effacement - correct answer ✔✔-The thinning of the cervix. Documented in measurements of 0-100%.
Changes progressively from long to paper thin.
True Labor - correct answer ✔✔-Contractions occur at regular intervals
-Interval between contractions gradually shortens
-Contractions increase in duration and intensity
-Discomfort begins in back and radiates around to abdomen
-Intensity usually increases with walking
-Cervical dilation and effacement are progressive
False Labor - correct answer ✔✔-Contractions are irregular
