    • Agents that can cause birth defects
    • Usually chemicals and environmental factors mother is exposed to during pregnancy
  3. Pica
    Pattern of eating non-food items like dirt, TP, and chalk
  4. What causes Physiological Anemia
    Increased in plasma volume that most often occurs during the 6th and 7th month of pregnancy.
  5. Chadwicks Sign






    Can
    be observed as early a 6-8 weeks after conception
    Bluish discoloration of the cervix, vagina, and labia caused by the hormone estrogen which results in venous congestion.
  6. Nagele’s Rule
    Way of calculating due date First day of last MP plus 7 days minus 3 months
  7. Gravida & Para
    • Gravida- Number of pregnancies
    • Para-Number of live births
  8. Purpose of Umbilical vein
    Carries oxygenated blood from the placenta to the growing fetus
  9. Medications that treat pre-term labor
    • -Antibiotics- prevent/treat infection
    • -Antenatal corticosteroids- speed up fetal lung development
    • -Tocolytic meds- slow down contractions and delay labor:
    • Mag sulfate
  10. Oxytocin is used…
    To induce labor by causing contractions and dilation of cervix
  11. Placenta Previa
    • Complication of pregnancy where placenta grows in the lowest part of womb.
    • Characterized by scant to bright red bleeding in 3rd trimester.

    • Usually 2-3 weeks prior to labor
    • Breathing becomes easier
  13. Characteristics of “True Labor”

    • More backache
    • Pain/contractions not relieved by walking
    • Cervix begins to progressively dilate
  14. Mechanism of labor movement for cephalic presentation
    • Descent: continuous descent of fetus through pelvis
    • Internal rotation: Head rotates to accommodate change of diameter of pelvis
    • External rotation: Shoulders drop down and turn to ant.position.
    • Head slowly turns to align with shouldersFlexion: head adapts to pelvis by flexing chin to chest
    • Extension: back of fetal head pivots under pressure of the symphysis pubis; delivered
  15. What does fundus measurements during pregnancy tell us?
    • Compared to est. gestational age (EGA) tells if fetus is growing at proper rate
    • If mismatched with EGA, can be cause of concern: Too much/little amniotic fluid, Breech birth
  16. Supine Hypotensive Syndrome
    • Caused by compression of vena cava
    • *Tx. Turn to L side
    • Change position frequently
    • Dangle and get up slow
  17. LOA
    • Left Occiput Anterior
    • Easiest fetus position to deliver
  18. Leopold’s Maneuver
    • Way of palpitating for the location/position of fetus in womb.
    • Three letter classification for position: First and last letter refers to landmark on mother, middle refers to fetus R or L, Ant. Or Post.,
  19. Infant landmarks with Leopold’s Maneuver
    • O- Occiput (best)
    • M- Mentum (chin)
    • S- Sacrum
    • Sc- shoulder
  20. How often should RN monitor FHT when contractions are 4-5 min apart in low-risk pt.?
    Q5min
  21. When does the 1st stage of labor end?
    Ends with complete effacement (thinning) and dilation (opening) of the cervix
  22. What is a maternal complication during the 3rd
    stage of labor?
    Hemorrhage???
  23. Calculating APGAR
    • Heart rate: (0-absent, 1-<100, 2->100)
    • Respiratory: (0-absent, 1-slow, irregular, weak cry, 2-good,strong-cry)
    • Muscle tone: (0- flaccid, 1- some flexion of extremities, 2-well flexed)
    • Reflex irritability: (0- no response, 1- grimace, 2- cough,vigorous cry, strong facial grimace)
    • Color: (0- blue, pale, 1- body normal, extremities blue, 2-normal skin coloring)
  24. Normal proportion of a newborn head to body length
    ¼ total body length
  25. What is the purpose of Narcan during labor?
    Narcotic antagonist in case of overdose
  26. Tracheoesophageal fistula-
    • An abnormal connection between the esophagus and the trachea.
    • Can be detected before delivery with ultrasound:Too much amniotic fluid (Polyhydramnios)
  27. Preventative measure for retinopathy
    Prevent excessive O2 saturation (when giving supplemental O2), especially in preemies
  28. Sickle cell crisis intervention
    • Hydrate
    • Oxygen* (crisis intervention?)
    • Pain medication
    • Support
