Question 1: What is the name of the thin, superficial, compact layer of deciduas enveloping the blastocyst?
- Decidua capsularis (Correct answer)
- Decidua parietalis
- Decidua Vera
- Decidua basalis
Correct answer: Decidua capsularis
The decidua capsularis is the thin, superficial layer of the endometrium that overlies and encapsulates the implanted blastocyst, separating it from the uterine cavity. It forms a protective covering around the developing embryo. This layer eventually thins and fuses with the decidua parietalis as the pregnancy progresses.
Question 2: When was the first Covid positive case reported in India?
- Gujarat
- Kerala (Correct answer)
- Maharashtra
- Tamilnadu
Correct answer: Kerala
The first confirmed case of COVID-19 in India was reported on January 30, 2020, in the state of Kerala. The patient was a student who had returned from Wuhan, China, the initial epicenter of the global outbreak. This marked the official beginning of the pandemic's presence within India.
Question 3: What is the name of the epithelial tissue present in uterine tubes?
- Simple
- Squamous
- Ciliated (Correct answer)
- Columnar
Correct answer: Ciliated
The uterine tubes (fallopian tubes) are lined with ciliated simple columnar epithelial tissue. The cilia beat rhythmically towards the uterus, creating currents that help propel the ovum from the ovary towards the uterus after ovulation. This ciliary action is crucial for successful fertilization and transport of the zygote.
Question 4: What is the name of the portion of the fetus that resides in the lower pole of the uterus?
- Lie
- Denominator
- Position
- Presentation (Correct answer)
Correct answer: Presentation
Fetal presentation refers to the part of the fetus that is closest to the internal os of the cervix and is felt by the examining finger during a vaginal examination. It indicates which part of the baby will enter the birth canal first. The most common presentation is cephalic, where the head is the presenting part.
Question 5: Maternal serum alpha-fetoprotein levels are reported to be low in
- Rh-isoimmunisation
- Open neural tube defect
- Down syndrome (Correct answer)
- Multiple pregnancies
Correct answer: Down syndrome
Low levels of maternal serum alpha-fetoprotein (MSAFP) are associated with an increased risk of Down syndrome (Trisomy 21). MSAFP is a component of prenatal screening tests, such as the quad screen, used to assess the risk of certain chromosomal abnormalities. Conversely, high MSAFP levels often indicate open neural tube defects.
Question 6: What is the name for the passive head movement caused by the neck untwisting endured during internal rotation?
- Extension
- Restitution (Correct answer)
- Descent
- Flexion
Correct answer: Restitution
Restitution is the passive movement of the fetal head after its delivery, where it untwists to realign with the fetal shoulders. This occurs as the neck, which was twisted during internal rotation, relaxes and the head rotates to face one of the maternal thighs. It is a normal mechanism of labor, preceding external rotation.
Question 7: The most typical reason for postpartum bleeding
- Atonic uterus (Correct answer)
- Placenta previa
- Abruptio placenta
- Bleeding disorders
Correct answer: Atonic uterus
Uterine atony, or an atonic uterus, is the most common cause of postpartum hemorrhage. It occurs when the uterus fails to contract adequately after childbirth, leaving blood vessels in the placental bed open and bleeding. Strong uterine contractions are essential to compress these vessels and prevent excessive blood loss.
