Exam Number 1 Study Guide Flashcards
Nagele’s Rule
LMP - 3 months + 7 days
Presumptive signs of pregnancy
amenorrhea nausea/vomiting fatigue urinary frequency breast changes quickening
Probable signs of pregnancy
Changes in pelvic organs/vascular congestion Abdominal enlargement Braxton hicks contractions Skin pigmentation changes Uterine soufflé Fetal outline Pregnancy test Ballottement (sharp push against uterine wall)
Positive/diagnostic signs of pregnancy
FHT
Fetal movement
Visualization in ultrasound
purpose of hCG in pregnancy
maintains corpus luteum, maintains pregnancy until placenta is developed
hPL in pregnancy
antagonist to insulin, breaks down fats to feed baby
estrogen in pregancny
stimulates uterine development, develops ductal system in breast
progesterone in pregnancy
secreted until placental production is sufficient, maintains pregnancy, develops acini and lobes of breast
relaxin
inhibits uterine activity, relaxes pelvic ligaments
vaccines in pregnancy
no attenuted live viruses due to possible teratogenic effects.
pertussis vacc in third trimester
first trimester screenings
ultrasound for nuchal translucency
second trimester screenings (6)
gestational diabetes HGB and HCT Amnio if advanced maternal age US Rhogam Vaccinate for pertussis (third)
Third trimester
strep b
Chadwick’s sign
bluish coloring of cervix
Goodell’s sign
softening of cervix
respiratory changes in pregnancy
thoracic breathing
nasal stuffiness
CV changes in pregnancy
blood volume increases, pulse increases 10-15 BPM, BP decreases slightly
skin and hair changes in pregnancy
Linea nigra, hyperactive sweat and sebaceous glands, significant hair shedding
Metabolic changes in pregnancy
Gain of 25-35 points, water retention, need for carbs increases in 2nd and 3rd trimester
Additional calorie intake in pregnancy
300 kcal/day
Protein intake in pregnancy
add 60g/day
Micronutrient needs in pregnancy
increase calcium, iron, zinc, B12, D
Recommended weight gain in pregnancy for normal, overweight, obese, and underweight mothers
Normal: 25-35lbs
overweight: 15-25 lbs
Obese: 11-20 lbs
Underweight: 28-40lbs
Folic acid supplements in pregnancy
.4mg/day, >.4mg/day if previous child had neural tube defects
Frequency of contractions
determined from beginning of one contraction to the beginning of the next
FHR assessment frequency during second stage
q5-15 minutes
What types of fetal lie are there? Which is most favorable?
Longitudinal- most favorable and common
Transverse- oblique and horizontal
Fetal presentation types
Cephalic: head. Occiput (best), brow
Breech: buttocks first
Shoulder
engagement
largest part of the presenting part reaches/passes through the pelvic inlet
station
where the presenting part is in relation to the ischial spines. From -3 to +3, with 0 being at the ischial spine.
Fetal position designation
R/L
O/M/S/A
A/P/T
effacement
thinning of the cervix
secondary force of labor
the use of the abdominal muscles
acme
peak of contraction
decrement
relaxation of a contraction
contractions are stimulated by
oxytocin
Cause of cervical dilation
fetal head pushing against cervix
lightening
indicates engagement, fetus settling into pelvic inlet. decreased SOB and increased urinary frequency
False labor pains
relieved by ambulation, bath, rest, mainly in lower abdomen and groin
4 Stages of labor
- onset of labor -> full dilation
- complete dilation -> birth
- birth of newborn -> birth of placenta
- delivery of placent -> 1-4 hrs PP, uterus contractions for bleeding control
First stage of labor latent phase
Beginning of regular contractions -> 4cm dilation
~8 hours nulliparous
~5 hours multiparous
First stage of labor active phase
4-> 7cm dilation, fetal descent. Cervical dilation 1.2-1.5cm/hour
First stage of labor transition phase: how long?
Cervical dilation from 8cm-> complete. 1 hour for multip, 3 hours for nullip.
Second stage of labor—description and length
Pushing phase- 10cm-> birth. 15 minutes multips, 2 hours for nullips. 3 Hours wth epidural.
Third stage of labor
30 minutes
Placenta separates.
Placenta examined after delivery for vessels and fetal (Schultze) and maternal (Duncan) sides to ensure no retained parts.
Fourth stage of labor
1-4 hrs after birth
250-500ml blood loss is normal, blood is redistributed
Fundus should be massaged and midway between SP and umbilicus.
BP lowered, tachy
Nursing interventions fourth stage of labor
Check lochia
Check UT firmness q15 x 4 hours
check for hemmorhoids
vital signs q5-15
Early decelerations FHR
normal, positive sign. Indicates head compression
Contraction pattern: latent phase
q10-30min -> q5-7
Contraction pattern: active phase
q2-5 -> q40-60s
