subjective
Urinary frequency N/V Breast tenderness Uterine/breast enlargement Hyperpigmentation of skin
S/S of pregnancy objective
Braxton hicks Abdominal enlargement Ballottement Goodells sign Chadwicks sign Hegars sign
Braxton hicks
when the womb contracts and relaxes
objective sign of pregnancy
Chadwicks sign
Dark blue or purplish red congested appearance of vag mucose
First trimester
Softening of uterus at junction with cervix
Hegars sign
First trimester
Softening of uterus at junction with cervix
Goodwells sign
Softening and cyanosis of the cervix
At of after 4 weeks
Ladins sign
Softening of uterus after 6 weeks
Pregnancy adaptation
Ptyalism
overproduction of saliva
GI pregnancy adaptations
Ptyalism Gingivitis Decreased peristalsis Hemorrhoids Heartburn N/V
Cardiovascular pregnancy adaptation
50% more blood
^ cardiac output
v blood pressure at first, increase later
^ RBC x2^ plasma causing hemodilution (anemia)
^ in demands for iron, fibrin, and clotting factors leading to hypercoagulable state
Resp pregnancy adaptations
Breathing more diaphragmatic
^ in O2 consumption
Congestion secondary to increased vascularity
Renal/urinary pregnancy adaptations
Dilation of pelvis and ureters
^ length/weight of kidneys
^ Glomerulofiltration rate (pee more)
^ kidney activity when lying down
Musculoskeletal pregnancy adaptations
Softening of sacroiliac ligaments
^swayback and upper spine extension
Lordosis
Waddle gait
Center of gravity shifts forward
Integument pregnancy adaptation
Hyperpigmentation
Linea nigra
Varicosities
Decline in hair growth
Increase in nail growth
Thyroid pregnancy adaptation
^BMR
Pituitary pregnancy adaptation
v TSH GH
inhibition of FSH and LH
^ Prolactin MSH oxytocin
Pancreas pregnancy adaptation
Insulin resistance in second half of pregnancy
Adrenal pregnancy adaptation
^ Cortisol and aldosterone
What does the placenta secrete
hCG hPL - insulin inhibitor relaxin estrogen progesterone
Pregnancy insulin and glucose
early pregnancy
^ in glucose demand due to baby growth
Fetus must make its own insulin
mid pregnancy
^ in insulin production to work against hPL and extra cortisol which desensitize insulin to give more sugar to baby
Nutrition pregnancy
intake IDRECTLY = wellbeing/outcome of birth
Need vitamins and minerals
Avoid mercury fish
Increase protein, iron, folate, and calories
MyPlate
Nutritional sugestion
1/2 plate, fruit and veg Whole grain ^ Fiber NO Hydrogenated fats 2 quarts of water daily 2 servings of fish weekly, 1 of them fatty
Bad food during pregnancy
NO Artificial sweeteners
NO Mercury fish (king, mackerel, ahi tuna, shark/sword fish) smoked seafood
NO processed meats (lunch meat, hotdogs, spreads)
NO soft cheeses (feta, brie, camembert)
NO unpasteurized milk
NO store made salads
Good fish for pregnancy
shrimp
salmon
pollock
catfish
up to 12 ounces
When is the embryo at greatest risk
17 to 56 days after conception
First prenatal visit points
Establish trust
Educate wellness
Detection/prevention of problems
Comprehensive history/examination/labs
Pregnancy history
suspicion of pregnancy
date of last period
s/s
urine or blood test for hCG
past history
what do you test urine and blood for for pregnancy
hCG
Gravida
I
II
Pregnant woman
first pregnancy
second pregnancy
etc
Para
woman who produced VIABLE/OR NOT offspring carrying 20 weeks or more
Primipara (Primip)
Multipara (Multip)
Nullipara (Nullip)
One birth after 20 week prego
2 or more pregnancies with viable offspring post 20 weeks
No viable offspring
Primipara
Multipara
Nullipara
One birth after 20 week prego
2 or more pregnancies with viable offspring
No viable offspring
GTPAL
Gravida Term births Preterm births Abortions Living children
Term birth
birth with 37 weeks gestation
preterm
birth with 20 to 37 weeks gestation
abortion
nonviable birth
less than 20 weeks gestation
OB history
GTPAL
So Primigravida means
first pregnancy
Menstrual history
Age at menarche Days in cycle Flow characteristics Discomforts Use of contraception
NAGELEs RULE
Calculate expected date of birth
Last menstrual period LMP date
LMP - 3 months + 7 days + 1 year
BEST method is ultrasound
Weight gain during pregnancy
BMI less than 18 - 28-40lb
BMI more than 25 - 12-25lb
Normal BMI 18 to 25 - 25-35lb
First Prenatal visit focus not sensitized
Rh - if negative, repeat at 28 weeks
if still negative give Rh immune Globulin (RhoGAm) to prevent sensitization
First Prenatal visit sensitized
Monitor closely blood work check ABX doppler ultrasound to fetal brain aminocentesis at 15 weeks to check fetal blood type Mother will see preinatologist
Rhogam will NOT work if woman is already sensitized
Good for 12 weeks
If mother is Rh sensitized Rhogam will
NOT work
Amniocentesis
blood type check at 15 weeks
If Rh is sensitized, mother will need to see a
perinatologist
Coombs test
determines weather mother has developed isoimmunity to the Rh antigen
detects antibodies harmful to fetus
If Coombs test is negative the woman is a candidate for
RhoGAM
Current standard of giving RhoGAM
between 28 and 32 weeks
again 72 hours after birth
Which Rh destroys Which
Rh negative blood will attack Rh positive blood
this is called Sensitization
Why is Rh a problem during second pregnancy
Mother and baby blood does not mix until birth, so first baby is good.
Once it mixes, mother develops antibodies, bad for second baby
Rh Sensitization can cause what in baby
Anemia
Jaundice
Hemolytic anemia (erythrocytosis fetalis)
Visits for pregnancy
Q4 weeks up to 28 weeks
Q2 weeks 29 to 36 weeks
Every week after 37 weeks to birth
What is measured during pregnancy follow ups
Wight and BP Urine for protein, glucose, ketones, nitrites Fundal height Quickening/fetal movement Fetal HR
Teach danger signs
Measure fundal height
Top of uterus to pubic bone
When does fetal movement begin
Second trimester
First perception of fetal movement
Range of movement determins
“Quickening”
Gentle fluttering
Pregnancy outcome
Good movement = good outcome
Fetal heart rate
Women lies down
Use doppler on abdomen
Normal range for fetus 110 to 160 bpm
