formation of a viable zygote
conception
the union of a spermatozoal nucleus with an egg nucleus to form a primary nucleus of an embryo
fertilization
the formation and development of germ cells, oocytes and spermatocytes
gamestogenesis
the period of development in the uterus from conception until birth
gestation
a process that interferes with the normal process of ovulation, fertilization and implantation
contraception
What is the term for the innermost layer of the uterine wall , the lining where the fertilized ovum implants?
Endometrium
In order to place a catheter, the nurse must visualize the female urethra.
Which phrase best describes where the female urethral opening is located?
between the clitoris and the vaginal opening
Where, in the female anatomy, does fertilization typically occur?
Ampulla of fallopian tube
At approximately 3 weeks after conception, the fertilized ovum differentiates into THREE primary germ layers. All of the fetal tissues and organs develop from these three germ layers.
What is the middle germ layer called and what does this middle layer give rise to?
Mesoderm; bones, muscles, cardiovascular system
In a healthy pregnancy, maternal and fetal blood never mix.
Where in the placenta - on a microscopic level - does the transfer of oxygen and nutrients occur between mother and fetus?
Intervillous space
Increased vascularity in the vaginal mucosa and cervix which results in violet-bluish color
chadwick sign
The first recognition of fetal movements by the mother
quickening
The capacity to live outside of the uterus
viability
Approximate increase in blood volume during pregnancy, above nonpregnancy levels
1500ml or 40-50%
A pigmented line extending from the symphysis pubis to the top of the fundus
linea negra
The normal baseline heart rate in a full-term fetus is between 110 and 160 beats per minute.
110
160
During fetal monitoring, which monitor is able to detect and record the frequency, duration and intensity of contractions?
Intrauterine pressure catheter (IUPC)
The nurse observes the fetal monitor and notes that the fetal heart rate baseline is 135 beats/min, with moderate variability, no decelerations and occasional accelerations.
According to the Three-Tier FHR Classification System, how would the nurse document this fetal heart rate tracing?
Category 1
What is the fetal heart rate baseline in the tracing?
140 beats per minute
This maternal labor position can help relieve “back labor,” often caused by a fetus in the “occiput posterior” position of the presenting part.
Hands and Knees position
This type of anesthesia is a nerve block, typically administered in the second stage of labor; it does not change maternal vital signs or fetal heart rate status.
Although the patient can still feel contractions, this method relieves pain in the vagina and perineum.
Pudendal
The nurse recognizes that a client is in true (versus false) labor when the client states:
“My contractions are now stronger and closer together.”
When planning care for a laboring woman whose membranes have ruptured, the nurse recognizes that the woman’s risk for _________________________ has increased.
Infection
The baby is born and the nurse assists with facilitating mother-baby skin-to-skin contact, while the provider watches for signs that the placenta is ready to deliver.
What stage of labor is this?
third
