  • Question 1 - The expected date of delivery of a human pregnancy can be calculated as:...

    Correct

    • The expected date of delivery of a human pregnancy can be calculated as:

      Your Answer: 40 weeks after last menstrual period

      Explanation:

      Expected date of delivery/estimated due date (EDD) is a calculated date (i.e., an estimation), determined by counting forward 280 days (40 weeks) from the first day of the woman’s last menstrual period.

    Incorrect

    • A patient is about to undergo an elective C-section. She wants to know how long it will take for her wound to completely heal.

      How much time does it take for healing by primary intention to reach full tensile strength?

      Your Answer: 24 weeks

      Correct Answer: 12 weeks

      Explanation:

      Wound healing typically undergoes different stages that include haemostasis, inflammation, proliferation and remodelling. The phases are often shortened when healing occurs by primary intention such as in a surgical wound. Remodelling, which is the major strengthening phase, takes about 3 weeks, while it takes a total of 12 weeks to reach maximum tensile strength.

    Correct

    • The β-hCG curve in maternal serum in a normal pregnancy peaks at:

      Your Answer: 10 weeks of pregnancy

      Explanation:

      During the first 8 weeks of pregnancy, concentrations of hCG in the blood and urine usually double every 24 hours. Levels of the hormone typically peak at around 10 weeks, decline until 16 weeks, then remain constant.

    Correct

    • Regarding amniotic fluid volume:

      Your Answer: Maybe predicted by ultrasound

      Explanation:

      Amniotic fluid can be measured with the help of ultrasound to gauge the amniotic fluid index. The normal value ranges between 8-18.
      Amniocentesis is a procedure by which amniotic fluid is removed. In rhesus disease, it appears yellow due to raised bilirubin levels.

  • Question 5 - Which of the following pubertal events is NOT mediated by gonadal oestrogen production?...

    Incorrect

    • Which of the following pubertal events is NOT mediated by gonadal oestrogen production?

      Your Answer: Vaginal cornification

      Correct Answer: Pubic hair growth

      Explanation:

      The role of androgens in the female includes acting as precursors for oestrogen production, anabolic effects, stimulation of axillary and pubic hair growth, sebum production, stimulation of bone formation, and stimulation of erythropoietin production in the kidneys.

    Correct

    • In a pregnant lady with polyhydramnios, the cause could be:

      Your Answer: Foetus with oesophageal-atresia

      Explanation:

      An underlying disease is only found in 17 % of cases in mild polyhydramnios. In contrast, an underlying disease is detected in 91 % of cases in moderate to severe polyhydramnios. The literature lists the following potential aetiologies: fetal malformations and genetic anomalies (8–45 %), maternal diabetes mellitus (5–26 %), multiple pregnancies (8–10 %), fetal anaemia (1–11 %), other causes, e.g. viral infections, Bartter syndrome, neuromuscular disorders, maternal hypercalcemia. Viral infections which can lead to polyhydramnios include parvovirus B19, rubella, and cytomegalovirus. Other infections, e.g. toxoplasmosis and syphilis, can also cause polyhydramnios.

  • Question 7 - Which of the following increases during pregnancy? ...

    Correct

    • Which of the following increases during pregnancy?

      Your Answer: Tidal Volume

      Explanation:

      Ventilation begins to increase significantly at around 8 weeks of gestation, most likely in response to progesterone-related sensitization of the respiratory centre to carbon dioxide and the increased metabolic rate. Significant alterations occur in the mechanical aspects of ventilation during pregnancy. Minute ventilation (or the amount of air moved in and out of the lungs in 1 minute) is the product of tidal volume and respiratory rate and increases by approximately 30–50 per cent with pregnancy. The increase is primarily a result of tidal volume, which increases by 40 per cent (from 500 to 700 mL), because the respiratory rate remains unchanged. The increase in minute ventilation is perceived by the pregnant woman as shortness of breath, which affects 60–70 per cent of women. This physiological dyspnoea is usually mild and affects 50 per cent of women before 20 weeks gestation, but resolves immediately postpartum.

    Correct

    • Which one of the following factors will most likely increase the chances of ovulation in female?

      Your Answer: LH surge

      Explanation:

      Different changes can occur during the menstrual cycle including an increased body temperature at the time of ovulation, thinning of the cervical mucus and few other changes, but it is the LH surge which is the most important factor necessary for ovulation.
      Mittelschmerz is characterised by recurrent midcycle pain which occurs around the time of ovulation.

  • Question 9 - What kind of biochemical changes occur during the luteal phase of menstrual cycle?...

    Incorrect

    • What kind of biochemical changes occur during the luteal phase of menstrual cycle?

      Your Answer: High luteinizing hormone level

      Correct Answer: High progesterone levels

      Explanation:

      Menstrual cycle can be divided into the follicular phase and luteal phase. In the luteal phase, there is an increase in progesterone secretion and LH levels are low. If the ova is fertilized, it is implanted in the endometrium. In case of failure in fertilization, there is gradual decrease in progesterone and LH levels.

    Incorrect

    • Regarding electronic fetal monitoring, which one of the following statements is true?

      Your Answer: Has moderate sensitivity & specificity

      Correct Answer: Has low specificity but high sensitivity

      Explanation:

      There are different ways of monitoring fetal heart rate during pregnancy. It can be done by just auscultation or by electronic fetal heart rate monitoring which is done with the help of an ultrasound machine and has a low specificity but high sensitivity.
