Question 1 of 5

Which hormone prepares the uterus for pregnancy?

Correct Answer: A

Rationale: Progesterone is the correct answer because it is responsible for preparing the uterus for pregnancy by creating a favorable environment for implantation and maintaining the uterine lining. Progesterone also helps prevent contractions of the uterus that could lead to the shedding of the uterine lining. Estrogen, FSH, and LH do not directly prepare the uterus for pregnancy but play roles in follicle development and ovulation.

Question 2 of 5

What is the function of the fallopian tubes?

Correct Answer: A

Rationale: The correct answer is A: Transport eggs from the ovaries to the uterus. The fallopian tubes serve as the pathway for the egg released by the ovary to travel towards the uterus for potential fertilization. This transportation process is essential for successful conception. Choices B, C, and D are incorrect because the fallopian tubes do not produce eggs, support implantation, or secrete estrogen. Eggs are produced in the ovaries, implantation occurs in the uterus, and estrogen is primarily produced by the ovaries and other endocrine glands.

Question 3 of 5

Which of the following is the correct order of the stages of labor?

Correct Answer: A

Rationale: The correct order of the stages of labor is Dilation, Expulsion, Placental (Choice A). Firstly, dilation refers to the opening of the cervix to allow the baby to pass through. Secondly, expulsion is when the baby is delivered. Lastly, the placental stage involves the delivery of the placenta after the baby is born. This sequence is crucial for a safe delivery and recovery. Choices B, C, and D are incorrect because they do not follow the natural progression of labor stages and may lead to complications if followed.

Question 4 of 5

Which of the following is a sign of pregnancy?

Correct Answer: A

Rationale: Morning sickness is a common sign of pregnancy caused by hormonal changes. It typically occurs in the first trimester. The other choices are not signs of pregnancy. Luteal phase defect is a menstrual cycle disorder, mature corpus luteum is a normal part of the menstrual cycle, and dysmenorrhea is painful periods. Thus, A is the correct answer as it directly relates to pregnancy.

Question 5 of 5

What is the role of the acrosome in sperm?

Correct Answer: C

Rationale: The acrosome in sperm contains enzymes that help it penetrate the egg during fertilization. These enzymes break down the outer layer of the egg, allowing the sperm to enter and fertilize it. This makes choice C the correct answer. Choices A and D are incorrect because the acrosome is not responsible for providing energy for movement or producing enzymes for sperm maturation. Choice B is also incorrect as storing sperm is not the primary role of the acrosome.
