OB and Neonatal Care Flashcards
Approximately how many cells does the embryo contain when it implants into the uterine wall?
32
Function of placenta
Synthesis of glycogen and cholesterol.
Metabolizes fatty acid.
Transfer of certain antibodies.
Performs respiratory gas exchange, transport of nutrients, excretion of wastes, and heat transfer.
Produces necessary hormones and serves as a barrier against harmful substance in woman’s circulation.
Premature rupture of membranes
Rupture of amniotic sac prior to the onset of labor.
Increasing risk of fetal infection or injury.
What is considered preterm?
Less than 37 weeks
Cardiovascular changes during pregnancy
HR elevates by 10-20 beats
CO increases by 30-50%
BP decreases by 10-15
Blood changes during pregnancy
Blood volume increases by 50%
RBC increase by 30#
Elevated RBC increases the need for iron
Respiratory changes during pregnancy
Respiratory minute volume increases by 40%
Increased CO2 during exhalation
GI changes during pregnancy
Morning sickness
Heartburn
Peristalsis decreases resulting in constipation
Musculoskeletal changes during pregnancy
Edema in LE
Approximately 27 lb weight gain
Most common cause of vaginal bleeding during the first nd second trimester?
Spontaneous abortion
Miscarriage
Causes of abortions.
Chronic illness in mother
Maternal exposure to toxic substances or illicit drugs
Fetal abnormalities
Abnormal attachment of placenta
Threatened abortion
Abortion that is impending or potentially occurring
Treatment for threatened abortion
Best rest to avoid activity or fluctuations in vital signs
Imminent abortion
Impending or threatened spontaneous abortion that cannot be prevented
Treatment for imminent abortion
Administering 250 mL bolus - repeat PRN NRB at 15L Emotional support Rapid transport Be alert for signs of shock
Incomplete abortion
Part of the products of conception is expelled, but some remain in the uterus.
s/s ectopic pregnancy
Sudden onset of lower abdominal pain and cramping
May or may not have vaginal bleeding
abruptio placenta
Premature separation of normally planted placenta from the wall.
s/s abruptio placenta
Sudden onset of severe abdominal pain
Decreased fetal movement
Decreased fetal hart tones
Minimal vaginal bleeding or none
placenta previa
Placenta is implanted low in the uterus and partially or fully obscures cervical canal
s/s placenta previa
Painless vaginal bleeding
Chronic HTN in pregnancy can cause
Retard growth and development of the fetus
Impaired liver and renal function
Pulmonary edema
Progress to life-threatening tonic-clonic seizures
Preeclampsia
HTN
s/s preeclampsia
Severe headache N/V Agitation Rapid weight gain Visual disturbances
pulmonary embolus SOB AMS Upper abd pain Myoclonus
Eclampsia
HTN
Seizure
Postpartum eclampsia
24 hours - 4 weeks after birth
Supine hypotensive syndrome
vena cava compression
s/s supine hypotensive syndrome
Nausea Dizziness Tachycardia Claustrophobia SOB Syncopal episodes
Gestational diabetes mellitus
Inability to process carbohydrates during pregnancy
Treatment for hyperemesis gravidarum
NRB 100% Blood glucose levels IV access Saline bolus Transport
Deceleration forces may cause :
abruptio placenta
uterine rupture
XABCDE
eXsanguinating hemorrhage Airway Breathing Circulation Disability Exposure
