OB Module 2: Antepartum Nursing Flashcards
Where is the female bladder located
anterior to the uterus and vaginal vault
The uterus leans ___ on top of the ____
forward on top of the bladder
In post partum, a distended bladder can do what?
displace the uterus and make it hared to stop a hemorrhage
Where is the female rectum located?
Immediately behind the uterus and vaginal vault
Retroverted
position of the uterus where the base of the uterus softens and can lean back toward the rectum rather than forward
this can affect when we hear Fetal heart beat or symptoms of pregnancy
Anteverted
position of the uterus where it tips forward from the cervix toward the abdomen
Fimbriae
capture the egg and have motion to move the egg along the tubes (on the side) to get it into the uterus
During ovulation, the ovum leaves where and enter where?
leaves the ovary and enters the fallopian tube
Fertilization generally occurs where
in the outer third of the fallopian tube
When does cell division of the ovum start>
Cell division starts as the ovum advances through the fallopian tube to the uterus where it will implant in the uterine wall lining
Ovulation
time each month that several eggs will move toward development with one usually being the one to become fully developed
Corpus Luteum
Once an egg is released, its ovary sac will become the corpus luteum
This will produce hormones until the placenta implants and can do it on its own
Pregnancy and Antepartum Care involves what things?
Diagnosis of the pregnancy
Signs and symptoms
General body system changes
Adaptation to pregnancy
Prenatal Care
Factors which influence pregnancy outcomes
Human pregnancy is designed to last for ___ weeks of “gestation.” Including the __ weeks before conception (when the last menstruation and ovulation were)
40 weeks; 2 weeks
so that is 38 weeks of dev
Pregnancy is described in terms of ___
trimesters
Are trimesters equal in length?
No - it is a 40 week period that does not split evenly
1st Trimester
1-12 Weeks
2nd Trimester
13-27 Weeks
3rd Trimester
28-40 Weeks
The major infant organs are formed by …
8 weeks (but that doesnt mean they are fully functional at 8 weeks)
Although the organs are formed, many essential systems are only …
minimally functional by week 24
After organ formation at 8 weeks, the rest of the pregnancy focuses on …
further development, growth, and maturation
Micro Preemies
Infants born between 23-27 weeks
Require considerable supportive care (their organs still needed more development time for example)
If they survive in the ICU nursery, they will have some disability in the end
Diagnosis of a Pregnancy Involves what kinds of signs
Presumptive Signs
Probable signs
Positive signs
What are Presumptive Signs of Pregnancy?
Signs the mother can perceive (subjective) that are not definitive since there are other illnesses that can mimic these symptoms
List the Presumptive signs of pregnancy
cessation of menses
N/V
Breast changes - enlargement and tenderness
Urinary frequency
fatigue
elevation of basal body temp
leakage of colostrum
excessive salivation at 4-14 weeks
quickening
Quickening
The mothers perception of fetal movement
18-20 weeks primips (first time mom)
16+ weeks multips (woman whose had babies before)_
What are probable signs of pregnancy
signs that are more objective and seen by the physician, increasing the likelihood of pregnancy, but they cannot be used to make a definitive diagnosis as other things could cause this
List the probable signs of pregnancy
Chadwick’s Sign
Hagar’s Sign
Piskacek’s Sign
McDonalds Sign
Goodells Sign
Abdomen enlargement
Uterine Soufflé
Palpation of fetal outline
Ballottement
Fetal movement witnessed
Positive pregnancy test
Skin color changes like appearance of Montgomery’s tubercles
Chadwick’s Sign
Blue or purple discoloration of the vulva and vaginal mucosae, including the vaginal portion of the cervix
begins around 8 weeks and beyond
Hegar’s Sign
The softening and compressibility of the uterine isthmus
Because of this softening the uterus may be anteflexed or retroverted
occurs at 6-12 weeks
Piskacek’s Sign
Asymmetry of the uterus with a rough, irregular contour on one side
The side that is rough is the side the placenta implanted on
Occurs at week 4-5
McDonald’s Sign
an ease in flexing the body of the uterus against the cervix
Goodell’s Sign
the softening of the cervix around 5 weeks
after some time it will harden again to not give way
Isthmus
area between the cervix and the upper body of the uterus
lower uterus
Why do McDonald’s Sign and Hegar’s Sign go together?
Because the isthmus softens so the heavier upper body of the uterus can press against the uterus
Mucus Plug
a product of the cervix made to prevent anything getting through the vaginal vault and impacting the pregnancy
Uterine Souffle
Blowing sound of increased blood flow around the uterine area
This occurs from the high pressure and increased vascularization
Montgomery’s Tubercles
small bumps emerging on the areola that secrete lubricant for the nipple
What are positive signs of pregnancy
signs that confirm a pregnancy
List the Positive signs of pregnancy
- Auscultation of fetal heart tones (10-12 weeks)
- Fetal movement perceived by the provider
- Visualization of the fetus through ultrasound or X ray
When can the fetal heart tones first be heard?
around 10-12 weeks
What can an ultrasound image confirm at 4-5 weeks and at 6 weeks?
4-5: Sac
6: Fetal Pole
We do not do what unnecessarily if we suspect a pregnancy?
Give an X Ray
Sometimes coincidentally we find out though when they are getting an X ray for something else
Pregnancy testing is done to assess levels of ___ produced by the fetus in either ___ or ___ serum to determine the presence of a viable pregnancy
hCG (human chorionic gonadotropin); urine; blood
What is the easiest to administer and least expensive method clinical pregnancy test?
Urine Based hCG test
When is a urine based hCG test done during the day, and when is the first time period it is accurate?
First morning voiding
10-14 days after the first missed menses
What can Serum hCG (blood) testing do that a Urine based test cannot?
- It is not dependent on time of day
- can detect a pregnancy earlier
- serial testing can also be used to assess the potential viability of a pregnancy
Ways to Date a Pregnancy
Naegele’s Rule
Uterine Sizing
Ultrasound
Naegele’s Rule
Dating a pregnancy based on the rule that the 1st day of the last menstrual cycle + 7 days and then - 3 months gives an estimated date of delivery
Uterine Sizing is a way to date a pregnancy, what is the size of the uterus at 8, 10, and 12 weeks?
8 - egg sized
10 - orange sized
12 - grapefruit and at the pelvic brim
At week 12, the uterus is grapefruit sized and now located at the pelvic brim so what can we do now?
Do an ultrasound to hear fetal heart tones
If we know the size of the uterus at week 12, but cannot hear heart tones…
we should be concerned about pregnancy’s viability
The earlier the ultrasound…
the more valid dating it gives and the more accurate it is
Why are ultrasounds less accurate later on?
After periods like 20 weeks of gestation, other factors begin to effect size
What does GPTPAL stand for when documenting a pregnancy
Gravida Parity Term Preterm Abortions Living
Its either written as something like G7P6 or G7T4P2A0L6
(GPTPAL) Gravida
any pregnancy regardless of gestation including the current pregnancy (miscarriage, abortion, live, etc)
(GPTPAL) Parity
any birth after 20 weeks gestation whether born alive or dead
(GPTPAL) Term
number of infants born at or after 38 weeks gestation
(GPTPAL) Preterm
Number of infants born between 20 weeks and 38 weeks
(GPTPAL) Abortions
number of infants born before 20 weeks gestation whether born alive or dead
(GPTPAL) Living
number of children alive currently
Why did we switch from just using Gravida and Parity to a system where were use Gravida, Term, Preterm, Abortions, and Living?
GP did not give us a good feel for those who had pre term babies and who may not be having babies that survive or life, so we had a system where we added TAL and replaced Parity with preterm
Nulligravida
Woman who has never been pregnant
Primigravida
Woman pregnant for the first time
Multipara
woman who has had two or more births at more than 20 week’s gestation
Multigravida
Woman in second or any subsequent pregnancy
also called Multips
Normal gestation is __ weeks
40
Where does the placenta usually implant?
Near the fundus (top of the uterus)
The uterus is mostly ___
muscle
As the pregnancy occurs, the uterus gets more __ and ___
distended and thicker
