26 Health Promotion And Pregnancy Flashcards
Abortion
Medical term used to refer to the loss of a pregnancy before 20 weeks’ gestation.
Amniocentesis
Involves removal of a small amount of amniotic fluid with a needle passed through the abdominal wall. This procedure is conducted in conjunction with an abdominal ultrasound scan, which enables the physician to visualize the location of the fetus, the placenta, and a pocket of amniotic fluid. Laboratory examination of the amniotic fluid can reveal valuable information regarding genetic factors such as sex and chromosomal abnormalities, health status, and maturity of the fetus.
Early Amniocentesis
Early Amniocentesis is preformed at approximately the 15th week of pregnancy and is used to detect biochemical or chromosomal abnormalities. This is the earliest point at which there is adequate amniotic fluid for testing. Testing at this time allows the mother to consider termination of the pregnancy before the legal point of viability is reach. The fetuses ability to survive outside the uterus is known as viability.
Viability
The fetuses ability to survive outside. The uterus is known as viability. In the past several decades, the age of viability has decreased as a result of technological advances. A fetus as young as 22 to 25 weeks gestation may survive outside of the mothers womb.
Later in pregnancy, Amniocentesis
Later in pregnancy, amniocentesis is used primarily to determine fetal lung maturity. It also may be performed to detect intrauterine infection and fetal distress, and to assess fetal laboratory values.
Maternity nurse
The maternity nurses in a unique position of providing care to the unborn. The knowledgeable maternity nurse can help a pregnant woman recognize the relationship between her physical status, and her care plan. Sharing information encourages the pregnant woman to participate in her own care, depending on her interest, need to know, and readiness to learn.
The goal of maternity care
The goal of maternity care is a healthy pregnancy with a physically safe and emotionally satisfying outcome for mother and infant. Consistent health, supervision and surveillance are paramount. Many pregnant women and their families are unfamiliar with the changes that accompany pregnancy. The knowledgeable maternity nurse can help a pregnant woman recognize the relationship between her physical status, and her care plan. Sharing information encourages the pregnant woman to participate in her own care, depending on her interest, need to know, and readiness to learn.
Physiology of Pregnancy
Understanding the physiologic changes of pregnancy begins with understanding the normal anatomy and physiology of the male and female reproductive systems.
Understanding the physiologic changes of pregnancy begins with understanding the normal anatomy and physiology of the male and female reproductive systems. A review of the menstrual cycle and related hormonal activity is particularly important. Also important is recognition that specific cells (over in the female and sperm in the male) carry genetic messages to their offspring. These cells are united to form a new individual with a unique genetic makeup.
Fertilization
During sexual intercourse, sperm carried in the male’s ejaculatory semen enter the female’s vagina.
By flagelation (whip-like movement), the sperm travel through the mucus of the cervical canal (if the mucus is receptive), enter the uterine chamber, and move into the ampulla-the outer third of the fallopian tube. If the timing is right, and ova has been produced, and is also within the ampulla of the tube; in such cases, fertilization may occur.
Fertilization is also called?
Conception
Fertilization is also called?
Conception
When does fertilization take place?
Fertilization (also called conception) takes place when the sperm joins or fuses with the ovum.
Approximately how much time is required for the fusion of the sperm into the ovum?
24 hours
Once fertilization has occurred, the new cell is referred to as a?
Zygote ( cell formed by the union of two reproductive cells) or a fertilized ovum.
What is a zygote?
Once fertilization has occurred, the new cell is referred to as a zygote ( cell formed by the union of two reproductive cells) or a fertilized ovum.
How many chromosomes does a zygote (fertilized ovum) carry?
A zygote (fertilized ovum) Carrie’s 46 chromosomes (44 autosomes and 2 sex chromosomes).
True or False
At the moment of fertilization, the sex of the zygote (fertilized ovum) and all other genetic characteristics are determined and do not change.
True
