Question | Answer |
---|---|
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 |
Leopold Maneuvers | palpation of uterine fundus to determine baby’s position |
Pudendal Block | anesthetic to the external nerves genitalia of female |
Duncan Mechanism | mothers side of the placental sac that is rough; “dirty” Duncan |
Schulze Mechanism | baby’s side of placental sac that is smooth; “shiny” Schulze |
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 |
