Materninty Nursing Chapter 7
Maternity Nursing Terms | Maternity Nursing - Defined |
---|---|
Acme | Peak, or period of greatest strength, of a uterine contraction. |
Crowning | Visibility of the fetal head in the birth canal before delivery. |
Decrement | Decrease of intensity (strength) of uterine contraction. |
Dilation of cervix | Stretching of cervical canal to size of opening large enough to allow passage of newborn. |
Engagement | Descent of the fetal presenting part to at least zero station (the level of the ishial spines in the maternal pelvis). |
Effacement | Thinning and shortening of the cervix before and during labor. |
Episiotomy | Surgical incision of the perineum before birth to permit delivery of newborn without lacerations to the area. |
Extension | Stretching out of part; opposite of flexion. |
External Rotation | The realignment of the fetal head with the shoulders after the head is delivered, and the alignment of the fetal shoulders with the mothers pelvis before delivery of the newborn. |
False labor | Irregular uterine contractions that do not result in cervical dilation. They do not get longer or become stronger. |
Fetal attitude | Relation of the fetal parts to one another. Normal attitude is one of flexion of the arms and legs. |
Fetal lie | Relation of the long axis of the fetus to the long axis of the woman. |
Fetal position | Relation of the designated part on the presenting fetal part to the front, sides, and back of the maternal pelvis. |
Fetal presentation | The fetal body parts that enter the maternal pelvis first. Three potential presentations are cephalic, breech, and shoulder. |
Increment | Increased intensity of a uterine contraction. |
Internal rotation | The turning of the fetal head until the occiput is directly under the maternal symphysis pubis in preparation for birth of the head. |
Labor | Process by which the fetus, placena, and membranes are expelled from the maternal uterus; parturition; childbirth. |
Lightening | Moving of the fetus and uterus downward into the pelvic cavity; engagement. |
Molding | Shaping the fetal head by overlapping of the cranial bones to facilitate movement through the birth canal. |
Show | Vaginal discharge during the first stage of labor. |
Station | Relation of the presenting fetal part to the pelvic ischial spines of the birth canal. |
The process of labor is actually an interaction of four very important variables: The | Pelvis, Passenger, Powers, and Psyche. |
Other factors (Vande Vuose, 1999) that can influence the process of labor, such as: | Preparation, Professional help, Procedures, & People. |
Preparation: | Attendance at prenatal classes reduces fear of the unknown. |
Position: | Maternal preferences for horizontal, vertical, sitting, squatting, or side-lying positions may influence the progress of labor. |
Preofessional help: | The presence of a supportive nurse or doula (specially trained labor coach) can coach the woman through the labor process. |
Procedures: | The number of vaginal examinations and other invasive procedures can interrupt concentration and rapport during the labor process. |
People: | The presence of supportive partners or family members can influence the smooth progress of labor. |
6 Possible occiput positions: | LOA, LOP, LOT, ROA,ROP, ROT |
LOA | Left occiput anterior |
LOP | Left occiput posterior |
LOT | Left occiput transverse |
ROA | Right occiput anterior |
ROP | Right occiput posterior |
ROT | Right occiput transverse |
Assessment of Uerine (Labor) Contractions | The characerisitics of labor contractions include Frequency, duraion, and intensity. |
