1. Which of the following is not a characteristic of an ideal contraceptive?

• A. Irreversible
• B. Easily available
• C. User-friendly
• D. Effective with least side effects

Correct answer: A

Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.

2. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

• A. Menorrhagia
• B. Metrorrhagia
• C. Polymenorrhoea
• D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.

3. 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.'

4. The follicular phase is to the __________ as the luteal phase is to the secretory phase.

• A. Postovulatory
• B. Menstrual
• C. Proliferative
• D. Ovulatory

Correct answer: C

Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.

5. 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.
