|---|---|
| Acme | peak or period of greatest strength of a uterine contraction |
| Analgesia | systemic agent that relieves pain without loss of consciousness |
| Anesthesia | loss of sensation, especially to pain, with or without loss of consciousness |
| Attachment | development of strong affectional ties as a result of interaction b/w an infant and a significant other |
| Bonding | development of strong emotional tie of a parent to a newborn, also called claiming or binding in |
| Braxton Hicks Contractions | irregular, usually mild UCs that occur through pregnancy & become stronger in 3rd trimester |
| Bloody Show | mixture of cervical mucus and blood from ruptured capillaries in the cervix; often precedes labor and increases with cervical dilation |
| Dilation/Effacement | opening of cervix/thinning of cervix |
| Engagement | descent of the widest diameter of the fetal presenting part at least zero station (ischial spines) |
| Lie | relationship of the long axis of the fetus to the long axis of the mother |
| Molding | shaping of the fetal head during movement through the birth canal |
| Position | relation of a fixed reference point on the fetus to the quadrants of the maternal pelvis |
| Presentation | fetal part that enters the pelvic inlet, or the presenting part |
| Station | measurement of fetal descent in relation to the ischial spines of the maternal pelvis (engagement) |
| Valsalva’s Maneuver | baring down to push out the fetus |
| VBAC | vaginal birth after cesarean |
| Episiotomy | surgical incision of the perineum to enlarge the vaginal opening |
| Crowning | appearance of the fetal scalp or presenting part at the vaginal opening |
| Primary Powers | UCs that cause progressive dilation and effacement of the cervix and descent of fetus |
| Secondary Powers | maternal pushing efforts during 2nd stage of labor |
| Nitrazine Test | pH test used to determine if amniotic sac has ruptured |

| Lumbar Epidural Block | regional block that provides analgesia and anesthesia for labor without sedation of the woman and fetus |
| Nadir | lowest point, such as lowest pulse rate in a series (usually no lower than 30-40 from baseline) |
| Uterine Resting Tone | degree of uterine muscle tension when the woman is not in labor or during the interval between labor contractions |
| Early Deceleration | slowing of FHR occurring during contractions as fetal head is pressed against moms pelvis/cervix;have a gradual dec from baseline |
| Variable Deceleration | caused by cond. that dec the flow through the umb.cord, occurring at times unrelated to contractions; not uniform in appearance,shape,duration,& degree of fall below baseline rate vary; fall & rise abruptly(w/in 30 sec)w/onset & relief cord compression |
| Late Deceleration | the slowing of the FHR after the onset of a uterine contraction (usually after the peak)& persisting after the contraction ends;uniform in appearance |
| Reassuring Patterns | (reactive) at least 2 FHR accelerations with or without fetal movement detected by the mom, occurring within a 20min period, peak at least 15 BPM above the baseline |
| Nonreassuring Patterns | (nonreactive) tracing does not demonstrate required characteristics of a reactive (reassuring) tracing within a 40min period |
