What is the purpose of progesterone in supporting early pregnancy?
- A. To increase fetal growth rates.
- B. To maintain the uterine lining and prevent menstrual shedding.
- C. To stimulate ovulation during the menstrual cycle.
- D. To regulate the release of other reproductive hormones.
Correct Answer: B
Rationale: The correct answer is B because progesterone plays a crucial role in maintaining the uterine lining to support implantation and prevent menstrual shedding. Progesterone prepares the uterus for the potential implantation of a fertilized egg by thickening the endometrium. If fertilization occurs, progesterone continues to support the pregnancy by ensuring the uterine lining remains intact to provide a nurturing environment for the developing embryo. Choices A, C, and D are incorrect because progesterone's main function in early pregnancy is not to increase fetal growth rates, stimulate ovulation, or regulate the release of other reproductive hormones.

A nurse is explaining the benefits of embryo freezing to a patient. What should the nurse emphasize?
- A. Frozen embryos have a higher success rate than fresh ones.
- B. It allows for future pregnancy attempts without additional egg retrieval.
- C. Embryo freezing eliminates the need for hormonal support during IVF.
- D. Only genetically modified embryos can be frozen.
Correct Answer: B
Rationale: The correct answer is B because embryo freezing allows for future pregnancy attempts without additional egg retrieval. This is important as it saves time, cost, and reduces physical burden on the patient. Choice A is incorrect as success rates are similar for frozen and fresh embryos. Choice C is incorrect because hormonal support is still required during IVF with frozen embryos. Choice D is incorrect as genetically unmodified embryos can also be frozen.
What is the primary purpose of a semen analysis in an infertility evaluation?
- A. To assess sperm count, motility, and morphology.
- B. To determine the presence of infections in the reproductive tract.
- C. To measure hormone levels affecting sperm production.
- D. To identify potential genetic anomalies in sperm.
Correct Answer: A
Rationale: The primary purpose of a semen analysis in an infertility evaluation is to assess sperm count, motility, and morphology. This is crucial as these factors directly impact male fertility. Sperm count indicates the quantity of sperm present, motility relates to their ability to move effectively towards the egg, and morphology assesses the shape and structure of sperm, which can affect their ability to fertilize an egg. Evaluating these parameters helps identify potential issues causing infertility. Other choices are incorrect as semen analysis primarily focuses on assessing sperm quality, not infections, hormone levels, or genetic anomalies in sperm.
