Detailed Explanations for Science Students||Already
Graded A+
1. Which hormone is primarily responsible for maintaining
pregnancy in the first trimester?
A. Estrogen
B. Oxytocin
C. Progesterone
D. Prolactin
Answer: C. Progesterone
Progesterone supports the endometrium and prevents uterine
contractions during early pregnancy.
2. The most reliable sign of ovulation is:
A. Mittelschmerz
B. Basal body temperature rise
C. Cervical mucus thinning
D. LH surge
Answer: D. LH surge
The luteinizing hormone (LH) surge directly triggers ovulation.
3. At what gestational age does the fetal heart rate typically
become detectable by Doppler?
A. 6–8 weeks
B. 10–12 weeks
C. 14–16 weeks
D. 18–20 weeks
,Answer: B. 10–12 weeks
Handheld Doppler devices usually detect fetal heart tones around 10–
12 weeks.
4. Which pelvic shape is most favorable for vaginal birth?
A. Android
B. Anthropoid
C. Platypelloid
D. Gynecoid
Answer: D. Gynecoid
The gynecoid pelvis has a round inlet and wide pelvic dimensions,
ideal for labor.
5. During pregnancy, cardiac output increases primarily due to:
A. Increased heart rate only
B. Increased stroke volume only
C. Both increased heart rate and stroke volume
D. Increased blood pressure
Answer: C. Both increased heart rate and stroke volume
Physiologic changes in pregnancy increase both components to meet
metabolic demands.
6. The most common cause of postpartum hemorrhage is:
A. Retained placental fragments
B. Genital tract lacerations
C. Coagulation disorders
D. Uterine atony
,Answer: D. Uterine atony
Failure of the uterus to contract effectively leads to excessive
bleeding.
7. Which finding is diagnostic of preeclampsia?
A. Edema alone
B. Hypertension and proteinuria after 20 weeks
C. Weight gain
D. Hyperglycemia
Answer: B. Hypertension and proteinuria after 20 weeks
Preeclampsia requires elevated blood pressure with signs of organ
involvement.
8. Which fetal presentation is associated with the highest risk
during vaginal birth?
A. Vertex
B. Face
C. Brow
D. Breech
Answer: D. Breech
Breech presentation increases risks of cord prolapse and birth
trauma.
9. The primary mechanism of action of combined oral
contraceptives is:
A. Thickening cervical mucus
B. Altering endometrial lining
C. Inhibiting ovulation
D. Blocking sperm motility
, Answer: C. Inhibiting ovulation
Estrogen and progestin suppress the LH surge needed for ovulation.
10. Which vitamin deficiency is associated with neural tube
defects?
A. Vitamin A
B. Vitamin D
C. Iron
D. Folic acid
Answer: D. Folic acid
Adequate folic acid intake before and during early pregnancy reduces
neural tube defects.
11. The normal fetal heart rate range is:
A. 90–120 bpm
B. 110–160 bpm
C. 120–180 bpm
D. 140–200 bpm
Answer: B. 110–160 bpm
This range indicates normal fetal autonomic nervous system function.
12. Which stage of labor involves cervical dilation from 6 cm to
complete?
A. Latent phase
B. Active phase
C. Second stage
D. Third stage
