Materninty Nursing

Materninty Nursing Chapter 7

Maternity Nursing TermsMaternity 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.
