Test #3
| Question | Answer |
|---|---|
| Gynecoid | Round inlet (50% of women) adequate for childbirth |
| Android | Heart shaped, resembles males pelvis, not adequate for chilbirth |
| Anthropoid | Oval Shaped (longer A/P) adequate for childbirth |
| Platypelloid | flattened pelvis (longer transverse)not adequate |
| Inlet | upper boundary of true pelvis (ridge or brim) |
| Pelvic Cavity | area between inlet and outlet |
| Outlet | lower boundary of true pelvis (diamaond shaped) |
| Anteriorposterior Inlet | Shortest Inlet diameter |
| Interspinous Diameter | Transverse diameter of Pelvic Cavity *where arrest of usually occurs |
| Transverse Outlet | Shortest Diameter |
| Pubic Arch | needs to be at 90degrees for childbirth |
| Effacement | shortening and thinning of the cervical canal |
| Dilation | enalargement of the cervical cananl |
| Pelvic Floor | helps fetus rotate anteriorly |
| Vertex | area between the fontanels |
| Bregma | anterior fontanel |
| Sinciput | the brow |
| Mentum | the chin |
| Suboccipitobregmatic diameter | shortes diameter- from undersurface of occiput to the center of the anterior fontanel |
| Occipitomental diameter | longest diameter- from the point of the chin to the posterior fontanel |
| Biparietal diameter | greatest transverse diameter- distance between the parietal protuberences |
| Fetal Attitude | degree of flexion *Fully flexed=good attitude |
| Fetal Lie | relationship of the long axis of the fetus to that of the mothers ( transeverse or longitudinal) |
| Vertex Presentation | most common- head is completely flexed on chest |
| Military Presentation | head without flexion or extension - anterior fontanel is the lower most part |
| Sinciput presentation | head partially extended |
| Face (Chin) Presentation | head is hyperextended |
| Complete Breech | knees and hips flexed |
| Frank Breech | Flexion of hips and extension of knees |
| Footling Breech | Extension of the hip and/or knee - can be single or double |
| Station | level of presenting part in relation to the ischial spine (above is - below is +) (positive towards birth) |
| Engagement | presenting part has passed into the true pelves (station 0) |
| Position | relationship of presenting part to specific quadrants in mothers pelvis (left/right anterior, left/right posterior) |
| Determining fetal presentation and position | 1.presenting part 2.reference point of present part 3. reference point on right or left side of mother 4. reference point anterior, posterior, or transverse |
| Voluntary Contractions | pushing, bearing down |
| Supine position during cx | less intense, more frequent |
| Lateral position during cx | more intense, more frequent |
| Upright position during cx | (standing, walking, squatting)stronger and more efficient in effacing and dilating |
| Descent | continuous downward movement through pelvis until birth of baby |
| Flexion | fetal head bends forward as it meets resistance |
| Internal Rotation | begins at level of ischial spine, face rotates posteriorly, occiput becomes midline beneath pubic arch |
| Extension | head must extend to be born, first the occiput, then face, finally chin |
| Restitution or External Rotation | after delivery of the head, it returns to a transevrse position, anterior shoulder is delivered first then the posterior shoulder |
| Expulsion | head and shoulders are lifted upward and trunk of body is deliverd (quick) |
