What is the Gestational Age:
- How far along in the pregnancy a person is. This is done by determining the EDC *Estimated day
of delivery*. Take the first day of the last menstrual period *LMP* and either 1. Subtract 3
months, add 7 days and add 1 year OR 2. Take LMP add 7 days and add 9 months.
What is Procardia/Nifedipine used for?
- Is a calcium channel blocker BUT ALSO
- Is used in preterm labor to slow contractions down
What is Magnesium sulfate used for?
- Used in preterm labor and lowers the seizure threshold, it’s a muscle relaxer. Using this you’ll
have a lesser chance of having seizures
What is Oxytocin used for?
- Causes contractions and inducing labor
What do prostaglandins used for?
They have effects on ovulation, fertility, discharging of the mature egg, changes in the cervix and
cervical mucus, tubal and uterine motility, sloughing of the endometrium *menstruation*, onset
of abortion *spontaneous/induced*, onset of labor *term and perterm*
- Help soften the uterus, lubricant *Cervidil/Dinoprostone*
- To pregnancy such as the Plan B bill *Cytotec/Misoprostol*
- Used to treat severe bleeding at childbirth as well as cause an abortion by causing uterine
contractions * Hemabate/ Carboprost tomethamine*
How does the ovarian cycle work?
- Ovulation occurs 14 days BEFORE next menstruation, this is based on a regular cycle.
o You’ll have usually 9 regular months and 2-3 not regular months. Finding out the
particular day is had.
- Sperm can live in the female system for up to 5 days
- The mature egg lives 12-24 hours then starts to degenerate.
,What are some rules or guidelines to menopause?
- A person has to have NO periods 1 year before menopause.
- Hot flashes/hormone changes happen 10 years before they stop having periods.
- The transitional phase is the decline of ovarian function and hormone production.
- The average age is 51 years old and ranges from 35-60 years of age.
Define Myotonia:
- Voluntary and involuntary contractions.
What are the 4 phases of a sexual response:
1. Excitement
2. Plateau
3. Orgasmic
4. Resolution
When is the most venerable time for the fetus?
- The first 8 weeks, this is when they are laying down their major organs, after this time frame
they aren’t as fragile.
- Implantation happens on day 7
What hormone is used to test for pregnancy?
- hCG is used for pregnancy tests
What is the placenta used for?
- It taps into the females hormones, shuts the ovaries down completely.
, - It transports O2 and nutrients to the baby
- Removes metabolic waste
- Has very large blood vessels that bring this to the baby
- It’s a barrier separating the maternal and fetus.
- Keep in mind that no blood is mixed until the baby is actually delivered.
- Amnion – Inner sac next to the fetus
- Chorion – outer sac next to uterine wall
Understanding different placenta placements:
A. Normal placenta – placed where its supposed to be
B. Placenta previa – low lying placenta, it covers the cervix
C. Placenta accrete – Chorionic villi extended into the myometrium, can’t separate following
delivery.
D. Abruptio placenta – Blood vessels broke, premature separation of the placenta prior to delivery.
Blood clot is formed, O2 and nutrients to the fetus is compromised.
How do you figure out Gravida Calculations:
- Stands for GTPAL
- G= Stands for the number of pregnancies
- T= Term, deliveries at 38 weeks and on
- P = Preterm, delivery after 24 weeks but before 38 weeks *37 weeks and 6 days*
o The alveoli have matured enough to bring O2, before this time period this can’t happen.
- A = Abortion, anything less than 22 weeks. Spontaneous, elective, therapeutic *because mom or
baby won’t make it through*
- L = Living, this is children living at home that you GAVE BIRTH TO. This doesn’t include adoptive,
or kids from other marriages.
- Example: G5 = T4, P0, A0, L4 = 4 kids at home and pregnant with 5 th baby.
o Those who have had multi births can give birth very quickly
