1. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

2. What are the Carunculae Myrtiformes?

• A. Tissues between the vagina and the perineum
• B. A component of the clitoral prepuce
• C. The remnants of the torn hymen
• D. Structures that partially close the vaginal introitus

Correct answer: C

Rationale: The Carunculae Myrtiformes are the remnants of the torn hymen. They are not tissues between the vagina and the perineum (Choice A), a part of the clitoral prepuce (Choice B), or structures that partially close the vaginal introitus (Choice D). Understanding the anatomy of the female reproductive system is crucial for healthcare professionals to provide accurate care and information.

3. What is the most common symptom in all clinical types of abortion EXCEPT:

• A. Lower abdominal pain
• B. Per vaginal bleeding
• C. Show
• D. Backache

Correct answer: C

Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.

4. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

Correct answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.

5. When does missed abortion occur?

• A. The fetus dies and is retained in utero with the placenta and membranes.
• B. All products of conception are expelled with minimal bleeding.
• C. The cervix remains closed, and the products of conception remain in the uterus.
• D. The cervix remains closed, but there is heavy bleeding.

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.
