1. 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.

2. 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.

3. What does Bidder's canal receive?

• A. Eggs
• B. Sperms
• C. Ammonia
• D. Oxygenated blood

Correct answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

4. Mrs. Banda is a patient at the ward with complaints of light menstrual periods, which occur at intervals greater than 35 days. Your diagnosis will be:

• A. Oligomenorrhea
• B. Menorrhagia
• C. Metrorrhagia
• D. Polymenorrhea

Correct answer: A

Rationale: The correct diagnosis for Mrs. Banda's condition is Oligomenorrhea. Oligomenorrhea is characterized by light menstrual periods occurring at intervals longer than 35 days. Choice B, Menorrhagia, refers to abnormally heavy menstrual bleeding. Choice C, Metrorrhagia, is bleeding at irregular intervals, and Choice D, Polymenorrhea, involves menstrual cycles occurring at intervals shorter than 21 days.

5. During the menstrual cycle, which hormone maintains the corpus luteum?

• A. Luteinizing hormone
• B. Follicle-stimulating hormone
• C. Progesterone
• D. Relaxin

Correct answer: A

Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
