Between the lambdoidal and sagittal sutures |
|
When does the posterior fontanelle close? |
2-3 months of age |
|
Area over the frontal bone |
Sinicput/brow |
|
Area between the 2 fontanelles |
Vertex |
|
Area over the occipital bone |
Occiput |
|
Overlapping of the bones which permits adaptations to the various diameters of the maternal pelvis |
Molding |
|
Allow cranial bones to move and overlap, molding or diminishing the size of the skull to pass through the birth canal |
Suture lines |
|
Relationship of the long axis of the fetus to the long axis of mother |
Fetal lie |
|
2 types of fetal lie |
1. Longitudinal 2. Transverse |
|
Degree of flexion a fetus assumes during labor or relation of the fetal parts to each other |
Fetal attitude |
|
3 types of fetal attitude |
1. Complete flexion 2. Moderate flexion 3. Partial flexion |
|
The fetal part that enters the pelvis first |
Fetal presentation |
|
How is fetal presentation determined? |
Combination of fetal lie and attitude |
|
3 fetal presentations |
1. Cephalic 2. Breech 3. Shoulder |
|
3 types of breech |
1. Frank breech 2. Complete breech 3. Footling breech |
|
What is PROM? |
Premature rupture of membranes |
|
Relationship of the presenting part to a specific quadrant of the maternal pelvis |
Fetal position |
|
4 fetal landmarks to describe the relationship of the presenting part to the pelvic quadrant |
1. Occiput (vertex) 2. Mentum (face) 3. Sacrum (breech) 4. Scapula or acromium process (shoulder) |
|
Describes the position of the presenting part in relation to the level of the ischial spine |
Station |
|
Station of crowning |
+3 to +4 |
|
Station of an engaged fetus |
0 |
|
6 mechanism of labor (cardinal movements) |
1. Descent 2. Flexion 3. Internal rotation 4. Extension 5. External rotation 6. Expulsion |
|
Downward movement of the biparietal diameter of the fetal head within the pelvic inlet |
Descent |
|
Settling of the presenting part of the fetus for enough into the pelvis to be at the level of the ischial spine |
Flexion |
|
Flexion of the head as it meets resistance from the soft tissues of the pelvis |
Internal rotation |
|
Head bends forward to present the smallest anteroposterior diameter to the birth canal |
Internal rotation |
|
Occurs as a result of negotiation of the fetal head to the curve of the pelvis |
Extension |
|
Rotation of the head, immediately after it is born, back to the diagonal or transverse position |
External rotation |
|
Complete birth of the body |
Expulsion |
|
2 powers of labor |
1. Primary power (involuntary contractions) 2. Secondary power (bearing down) |
|
Psychological state or feelings that a woman brings into labor |
Psyche |
|
Common position of mother during labor |
Lithotomy position |
|
Begins with onset of true labor contractions and ends with complete dilation and effacement of the cervix |
First stage |
|
Begins from full cervical dilation to fetal expulsion |
Second stage |
|
Begins from expulsion of the baby to placental expulsion |
Third stage |
|
4 signs of placental separation |
1. Lengthening of umbilical cord 2. Sudden gush of blood 3. Change in shape of uterus 4. Appearance of placenta at vaginal opening |
|
Normal blood loss |
300 to 500 ml |
|
Begins from the delivery of placenta to the first 1-2 hours after birth |
Fourth stage |
|
3 lochia discharges |
1. Rubra (1-3) 2. Serosa (4-10) 3. Alba (11-21) |
|
Bloody red, small clots and fleshy earth odor |
Rubra |
|
Pink or brown lochia |
Serosa |
|
Creamy, yellowish lochia |
Alba |
