1. 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.

2. Which of the following is used to differentiate abdominal mass from pelvic mass on clinical examination?

• A. Size
• B. Site
• C. Margins
• D. Lower border

Correct answer: D

Rationale: The lower border is used to differentiate between an abdominal mass and a pelvic mass during clinical examination. The lower border of the mass provides important information about its location and origin. The size (Choice A) alone may not always clearly distinguish between abdominal and pelvic masses. The site (Choice B) and margins (Choice C) are also important factors, but they are not as specific in differentiating between abdominal and pelvic masses as the lower border.

3. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

4. 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.

5. Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?

• A. Progesterone/estrogen
• B. LH/FSH
• C. FSH/LH
• D. Glucagon/insulin

Correct answer: B

Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.
