REVIEW
Comprehensive concept review for
maternal-newborn nursing.
QUIZ 1: REPRODUCTIVE ANATOMY, PHYSIOLOGY, & PRENATAL CARE
1. What is the primary hormone responsible for ovulation?
A: Luteinizing hormone (LH).
2. Where does fertilization typically occur?
A: The ampulla of the fallopian tube.
3. Which hormone maintains the uterine lining during early pregnancy?
A: Progesterone.
4. What is the normal duration of pregnancy in weeks?
A: 40 weeks from the first day of the last menstrual period (LMP).
5. What is Naegel’s rule?
A: Estimate expected date of delivery (EDD): take first day of LMP, subtract 3 months, add 7
days.
6. Which prenatal lab test screens for neural tube defects?
A: Maternal serum alpha-fetoprotein (MSAFP).
7. When is the first trimester?
A: Weeks 1–13.
8. What is Chadwick’s sign?
A: Bluish-purple coloration of the cervix, vagina, and vulva due to increased vascularity.
9. Which vaccine is contraindicated in pregnancy?
A: MMR (live vaccine).
, 10. Recommended weight gain for normal BMI pregnancy?
A: 25–35 lbs.
QUIZ 2: FETAL DEVELOPMENT & ANTEPARTUM ASSESSMENT
11. When can fetal heartbeat first be detected by Doppler?
A: 10–12 weeks gestation.
12. The fetal structure that allows blood to bypass the lungs is:
A: Ductus arteriosus.
13. Which vitamin supplementation is critical pre-conception to prevent neural tube
defects?
A: Folic acid (400–800 mcg/day).
14. What does the Apgar score assess?
A: Newborn’s condition at 1 & 5 minutes after birth (Heart rate, Respiration, Muscle tone, Reflex
irritability, Color).
15. At what gestational age is lung surfactant production typically adequate?
A: By 35–36 weeks.
16. Purpose of the biophysical profile (BPP)?
A: Assess fetal well-being via ultrasound (tone, movement, breathing, amniotic fluid volume)
and NST.
17. Normal fetal heart rate (FHR) range:
A: 110–160 bpm.
18. Placenta function includes all except:
A: Fetal gas exchange, nutrition, waste removal, hormone production. (It does not produce
urine.)
19. Quickening is usually felt by mother at:
A: 18–20 weeks in primigravida, earlier in multigravida.
20. In fetal circulation, oxygenated blood from placenta enters via:
A: Umbilical vein → ductus venosus → inferior vena cava.
QUIZ 3: INTRAPARTUM CARE (LABOR & DELIVERY)
, 21. The five Ps of labor:
A: Passenger (fetus), Passage (pelvis), Powers (contractions), Position (maternal), Psyche.
22. Which fetal position is most favorable for delivery?
A: Occiput anterior (OA).
23. Normal duration of active phase of first stage labor?
A: About 3–5 cm to 7 cm dilation, contractions stronger, lasting 45–60 sec, 3–5 min apart.
24. What defines “prolonged deceleration” in FHR monitoring?
A: Deceleration lasting >2 minutes but <10 minutes.
25. What is station 0?
A: Fetal presenting part at level of ischial spines.
26. When should amniotomy be avoided if possible?
A: If fetus is not engaged (floating), due to cord prolapse risk.
27. Nursing care for cord prolapse:
A: Knee-chest position, relieve pressure on cord, prepare for emergency cesarean.
28. True vs. false labor:
A: True labor = contractions increase in frequency, duration, intensity with cervical change; false
labor = no cervical change.
29. Meconium-stained amniotic fluid may indicate:
A: Fetal distress (but not always); requires neonatal resuscitation readiness.
30. When is oxytocin (Pitocin) contraindicated?
A: With previous classical uterine incision, cephalopelvic disproportion, fetal distress, placenta
previa.
QUIZ 4: HIGH-RISK INTRAPARTUM & OB EMERGENCIES
31. Sign of placental abruption:
A: Dark red bleeding, painful, rigid uterus, fetal distress.
32. Sign of placenta previa:
A: Painless bright red bleeding in 3rd trimester.
33. Nursing priority for eclampsia seizure:
A: Ensure airway, safety, side-lying position, give MgSO₄ as ordered, prepare for delivery.
, 34. Therapeutic MgSO₄ level range:
A: 4–8 mg/dL; toxicity >8 mg/dL (loss of reflexes, respiratory depression).
35. What is HELLP syndrome?
A: Hemolysis, Elevated Liver enzymes, Low Platelets (complication of preeclampsia).
36. Management for uterine atony:
A: Fundal massage, oxytocin, methylergonovine, carboprost, possible surgery.
37. Early decelerations are caused by:
A: Head compression (normal pattern, mirrors contraction).
38. Variable decelerations indicate:
A: Cord compression; change position, amnioinfusion possible.
39. Late decelerations indicate:
A: Uteroplacental insufficiency; improve placental perfusion (lateral position, O₂, IV fluids, notify
provider).
40. Risk factors for shoulder dystocia:
A: Gestational diabetes, macrosomia, prolonged second stage, maternal obesity.
QUIZ 5: POSTPARTUM CARE
41. Normal postpartum fundal position 12 hours after delivery:
A: At umbilicus or 1 cm below.
42. Lochia rubra lasts:
A: 1–3 days postpartum; bright red, small clots normal.
43. Postpartum blues peak when?
A: Days 3–5, resolves by day 10–14.
44. S/S of postpartum hemorrhage:
A: Saturing >1 pad/hour, tachycardia, hypotension, boggy uterus.
45. Best method to assess for postpartum DVT?
A: Homans’ sign is unreliable; use ultrasound if suspected.
46. Nursing intervention for uterine subinvolution:
A: Assess for retained placental fragments, infection; may need oxytocics or D&C.
