1. Which of the following Leopold maneuvers assesses the fetal lie?

• A. Fundal grip
• B. Umbilical grip
• C. Pawlick grip
• D. Pelvic grip

Correct answer: A

Rationale: The correct answer is A: Fundal grip. Fundal grip is a specific Leopold maneuver used to assess the fetal lie by palpating the upper abdomen to determine the position of the baby's back and presenting part. This maneuver helps healthcare providers understand the orientation of the fetus within the uterus. Choice B, Umbilical grip, is not a recognized Leopold maneuver and does not assess fetal lie. Choice C, Pawlick grip, and choice D, Pelvic grip, are also not part of the standard Leopold maneuvers used to determine fetal lie.

2. What is the role of the progesterone hormone?

• A. Stimulates the development of the nipple and duct system in the breast.
• B. Stimulates the storage of milk.
• C. Stimulates the secretion of relaxin.
• D. Stimulates the development of glandular tissue in the breast.

Correct answer: A

Rationale: The correct answer is A. Progesterone hormone's role includes stimulating the development of the nipple and duct system in the breast. This hormone is crucial for preparing the breast for potential pregnancy by promoting the growth of structures necessary for milk production. Choices B, C, and D are incorrect because progesterone primarily focuses on preparing the breast for lactation rather than directly stimulating milk storage, relaxin secretion, or glandular tissue development.

3. What is the most common site for an ectopic pregnancy?

• A. Isthmus
• B. Ampulla
• C. Interstitial
• D. Infundibulum

Correct answer: C

Rationale: The correct answer is C, Interstitial. An ectopic pregnancy most commonly occurs in the interstitial portion of the fallopian tube. This is because the interstitial part is narrow and not suitable for the growing embryo, leading to implantation outside the uterus. Choices A, B, and D are incorrect because although ectopic pregnancies can occur in various locations, the interstitial portion of the fallopian tube is the most frequent site for such pregnancies.

4. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

5. Where does the ovum receive the sperm?

• A. Animal pole
• B. Vegetal pole
• C. Zona pellucida
• D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.
