Hardest 20 MCQs – Pregnancy Timeline, EDD, IUFD, Uterine Height
1. A woman with LMP 14 Feb 2025 presents for dating scan. CRL suggests 9w2d, differing from LMP by 10 days. What is the correct EDD?
A. Use LMP-based EDD only
B. Use USG-based EDD because difference >7 days
C. Average both values
D. Repeat USG after 2 weeks
Correct: B
In 1st trimester, revise EDD if difference >7 days.
2. IUFD diagnosed at 32 weeks. Fibrinogen is 120 mg/dL. Next step?
A. Expectant management
B. Immediate induction of labour
C. Cesarean section
D. Wait 1 week for spontaneous labour
Correct: B
Low fibrinogen indicates DIC risk → deliver early.
3. Fundal height is 34 cm at 28 weeks. Most likely diagnosis?
A. IUGR
B. Wrong dates
C. Polyhydramnios
D. Oligohydramnios
Correct: C
FH greater than expected → polyhydramnios/multiple pregnancy.
4. Woman presents with absent fetal movements. USG shows absent cardiac activity & overlapping skull bones. Diagnosis?
A. Missed abortion
B. IUFD with Spalding sign
C. Anencephaly
D. Severe IUGR
Correct: B
Spalding sign = overlapping skull bones → IUFD.
5. Quickening occurs at what gestational age in a primigravida?
A. 12 weeks
B. 14–16 weeks
C. 18–20 weeks
D. >22 weeks
Correct: C.
6. A woman at 20 weeks has bleeding and placenta previa. What risk increases?
A. IUFD due to abruption
B. IUFD due to fetal anemia
C. IUFD due to maternal hypotension
D. Both A & B
Correct: B
Placenta previa → fetal blood loss → anemia → IUFD.
7. Best investigation to diagnose IUFD?
A. NST
B. Doppler
C. Ultrasound with cardiac activity
D. CTG
Correct: C.
8. Uterine height at 36 weeks normally corresponds to:
A. Umbilicus
B. Xiphisternum
C. 2 cm below umbilicus
D. Above xiphisternum
Correct: B.
9. After IUFD, coagulation profile monitoring should be done every:
A. 4 hours
B. 6 hours
C. 12 hours
D. 24 hours
Correct: C.
10. A lady is G4P2L1A1. What does this mean?

C. 4 pregnancies, 1 viable birth
D. None
Correct: A.

D. Mix of parameters
Correct: B.
12. Which is a probable sign of pregnancy?
A. Quickening
B. Fetal heart sounds
C. Positive β-hCG test
D. Palpable fetal parts
Correct: C.
13. Woman with IUFD for 4 weeks is most at risk of:
A. Sepsis
B. PPH
C. DIC
D. Shock
Correct: C.
14. Fundal height lower than expected indicates:

A. Cesarean section
B. Misoprostol induction
C. Expectant waiting 1 week
D. Foley catheter + oxytocin
Correct: B.
16. Positive sign of pregnancy?
A. Chadwick sign
B. Hegar sign
C. Palpation of fetal movement by examiner
D. Amenorrhea

C. Serum β-hCG
D. Fetal heart sounds
Correct: C.
18. Abruption leading to IUFD is mainly due to:
