Probable signs of pregnancy

Changes that make the examiner suspect a woman is pregnant. Abdominal enlargement, cervical changes, Hegars sign which is softening and compressibility of the lower uterus, Chadwicks sign which is a deep purple blue color of the vaginal mucosa, Goodells sign which is softening of the cervical tip, Ballotement which is rebound of the fetus, Braxton Hicks contractions, positive pregnancy test, fetal outline felt by examiner


Positive signs of pregnancy

Signs that are only explained by pregnancy they include fetal heart cells, visualization by an ultrasound, fetal movement felt by the examiner


McDonald's method

Measuring the fundal height in cm between 18-30 wks



Gravida-number of pregnancies
Multi 2 or more
Term 38 wks
Preterm <20 wks or 2 lbs
Living children



Toxoplasmosis (cat) flu like, fever
rubella joint and muscle pain, rash
cytomegalovirus (member of herpes) droplet, mono like
These can cross the placenta and effect the fetal development



Conflicting feelings such as having joy and sorrow at the same time


Types of birthing plans

Dick-read: Childbirth without fear. Control breathing and relaxation. Completely relax between contractions.
Lamaze: is to promote a healthy, natural, safe approach with early parenting
Leboyer: Births without violence stress is decreased. Dim room soft voices, warm room, Waterbirth
Bradley: Partners involvement as a coach. Natural breathing, relaxation, nutrition, exercise


Weight gain during pregnancy

3 to 4 pounds during the first trimester, 1 pound a week after that. A total of 25-35 pounds.
increase of 340 cal a day during the second trimester.
Increase 452 a day during the third trimester.
If breast-feeding take an additional 330 The first six months and 400 the second six months.


Folic acid

Leafy vegetables, dried peas and beans, seeds, orange juice, and other foods that are fortified such as breads, cereals, grades. 600 µg during pregnancy and 500 while lactating.


Iron foods

gross body movements at least three extensions in 30 minutes fetal tone at least one episode of extension and flexion
amniotic fluid volume



Used to supress cell division in ectopic pregnancy
Avoid alcohol and folic acid.
Avoid sun exposure.



Group b, test 35-37 wks, Trt pcn G in labor
Chlamydia, Trt zithromax ro erythromycin
Erythromycin given to babies eyes for ophthalmia neonatorum

Risk factors include less than two years between pregnancies, heavy periods, Diet low in Iron.
Signs and symptoms include fatigue, irritability, headache, shortness of breath, palpitations, pica, pallor, brittle nails, decreased H and H
60 mg iron


Gestational diabetes

Glucola screening test done at 24 to 28 weeks. Greater than 140 needs further testing

3 hr test: Overnight fasting, avoid caffeine, no smoking. 100 g glucose given and retested at one, two, three hours.

Daily kick counts, diet and exercise, insulin admin,


Gestational hypertension

>140/90 after 20 wks, or >30/15 increase from baseline. No protein or edema, returns 12 wks postpartum.


Mild preeclampsia

Gestational hypertension with 1 to 2 protein urea, weight gain more than 4.4 pounds per week in the second and third trimester, mild edema


Severe preeclampsia

>160/100, 3 to 4 protein urea, oliguria, elevated creatinine greater than 1.2, cerebral or visual disturbances such as headache and blurred vision, hyperreflexia, ankle clonus, pulmonary or cardiac involvement, extensive Edema, liver dysfunction, epigastric and right upper quadrant pain, thrombocytopenia



Severe preeclampsia with seizure activity or coma. Usually preceded by headache, severe epigastric pain, hyperreflexia, hemoconcentration.


Heart disease with pregnancy

Class-1 exhibits no symptoms with activity.
Class 2 have symptoms with ordinary exertion.
These are candidates for a normal pregnancy and delivery.
Class III display symptoms with minimal exertion and maybe bedrest during pregnancy.
Class IV is the client has symptoms at rest and is not a candidate for pregnancy.

Restrict NA and follow cardiac diet.
Inderal to lower BP and treat tachycardia
Gentamicin prophylactic abx
Ampicillin prophylactic abx
Avoid foods high in vitamin k
Digoxin to increase CO or for fetal tachycardia



Relaxes uterine smooth muscles to prevent contraction. Should be discontinued if there are signs of pulmonary edema which includes chest pain, shortness of breath, respiratory distress, wheezing in crackles, productive cough. Restrict oral and IV fluids to reduce risk of pulmonary edema. Withhold if heartrate is above 120 to 140.



An anti-inflammatory that blocks prostaglandins and suppresses uterine contractions. Discontinue if signs of pulmonary edema. Should not exceed 48 hours. Only used for gestational age less than 32 weeks. Monitor for postpartum hemorrhage. Given with food or rectally.


Mechanisms of labor. 7

Internal rotation
Restitution and external rotation for shoulders


Stages of labor

Stage 1: 12 1/2 hrs, onset labor, complete dilation, 1cm per hr for first time, 1 1/2 for others
Latent: 4-6 hrs, 0-3, contractions 30-45 sec, 5-30 min apart
Active: 2-3 hrs, 4-7, 40-70 sec, 3-5 min, some decent
Transition: 20-40 min, 8-10 sec, 45-90, 2-3 min,

Stage 2: 5-120 min, intense contractions 1-2 min, birth

Stage 3: placenta delivery; shiny Schultz, dull duncan(maternal side)

Stage 4: 1-4 hrs, stabilization, lochia scant to moderate


Pain meds for labor

Stadol and Nubian do not cause resp depression, IM IV

Demerol, fentanyl, are also used.

Labor should be at least 4 cm dilated and well established.


FHR monitoring

Baseline 110-160
Variability: absent is non reassuring
Minimal 25
Periodic changes are with contractions, episodic are not

Category 1: normal baseline, moderate variability, possible accelerations, possible early decels, no variable or late decels

Category 2: tachy or Brady baseline, absent, minimal, or marked variability, decels >2<10, late decels, no accelerations with stimulation

Category 3: sinusoidal pattern, absent variability with recurrent variable or late decels, bradycardia,


How often to monitor FHR

Low risk: latent 60
Active 30,
2nd stage 15

High risk: latent 30
Active 15
2nd 5
