1. What does the umbilical cord contain?

• A. Pluripotent stem cells
• B. Cord blood stem cells
• C. Blood stem cells
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

2. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

• A. Copper-T
• B. Diaphragm
• C. Contraceptive pills
• D. Condom

Correct answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

3. 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.

4. Treatment for condylomata acuminata includes the following EXCEPT:

• A. Vulvectomy
• B. Podophyllin application
• C. Laser therapy
• D. Electrocautery

Correct answer: A

Rationale: The correct answer is A. Vulvectomy is not a standard treatment for condylomata acuminata, which are genital warts caused by human papillomavirus (HPV). Surgical removal of the vulva (vulvectomy) is an extreme measure and not typically indicated for treating this condition. Choices B, C, and D are valid treatments for condylomata acuminata. Podophyllin application, laser therapy, and electrocautery are commonly used to remove or destroy genital warts caused by HPV. These treatments aim to eliminate the visible warts and clear the infection.

5. Which of these methods can be used for the transfer of zygote or early embryo into the fallopian tube?

• A. GIFT
• B. IUT
• C. ZIFT
• D. ICSI

Correct answer: C

Rationale: The correct answer is C, ZIFT (Zygote Intrafallopian Transfer). ZIFT involves transferring a zygote or early embryo into the fallopian tube. GIFT (Gamete Intrafallopian Transfer - A) involves transferring unfertilized eggs and sperm into the fallopian tube for fertilization to occur inside the woman's body, not a zygote or early embryo. IUT (Intrauterine Transfer - B) is not specifically for transferring the zygote or early embryo into the fallopian tube, but rather into the uterus. ICSI (Intracytoplasmic Sperm Injection - D) is a technique where a single sperm is injected directly into an egg, not related to transferring embryos into the fallopian tube.
