- A. The baby is female with a normal number of chromosomes.
- B. The baby is hermaphroditic male with female chromosomes.
- C. The baby is male with an undisclosed genetic anomaly.
- D. There is insufficient information to answer this question.

A nurse is discussing fertility preservation options for a young woman undergoing cancer treatment. What should the nurse highlight?
- A. Embryo freezing is the only effective preservation method.
- B. Egg freezing is an option for women who are not ready to fertilize eggs.
- C. Fertility preservation must wait until cancer treatment is completed.
- D. No preservation methods exist for women in this situation.
Correct Answer: B
Rationale: The correct answer is B because egg freezing allows women to preserve their fertility before cancer treatment. It is a viable option for those not ready to fertilize eggs. Choice A is incorrect as embryo freezing is not the only method. Choice C is incorrect as fertility preservation should be discussed before cancer treatment. Choice D is incorrect as egg freezing is a valid preservation method.
During a preconception consultation, a patient asks about factors affecting egg quality. What should the nurse explain?
- A. Age is the primary factor influencing egg quality.
- B. Diet has no impact on egg quality.
- C. Hormonal treatments guarantee improvement in egg quality.
- D. Exercise is the only way to enhance egg quality.
Correct Answer: A
Rationale: The correct answer is A: Age is the primary factor influencing egg quality. As a tutor, I will explain this by stating that the quality of a woman's eggs declines with age due to factors like genetic abnormalities and decreased mitochondrial function. This decline can affect fertility and increase the risk of chromosomal abnormalities in offspring.
For the incorrect choices:
B: Diet can impact egg quality by providing essential nutrients, so this choice is incorrect.
C: Hormonal treatments may help with fertility but do not guarantee improvement in egg quality, making this choice incorrect.
D: Exercise can contribute to overall health but is not the only way to enhance egg quality, making this choice incorrect.
In summary, age is a crucial factor affecting egg quality, while diet, hormonal treatments, and exercise play roles but are not primary influencers.
A young couple is contemplating starting a family. Which is the best time for genetic counseling?
- A. Now, before they become pregnant
- B. As soon as they have a positive pregnancy test
- C. In the second trimester
- D. In the third trimester
Correct Answer: A
Rationale: The correct answer is A: Now, before they become pregnant. This is the best time for genetic counseling because it allows the couple to understand their genetic risks, receive information on potential hereditary conditions, and make informed decisions before conception. Genetic counseling before pregnancy enables proactive planning and consideration of options such as genetic testing or alternative reproductive methods if necessary. Choices B, C, and D are incorrect as genetic counseling is most effective and beneficial when done prior to conception to ensure optimal outcomes and informed decision-making.
A patient undergoing IVF asks about the risks of transferring multiple embryos. What should the nurse discuss?
- A. Increased chances of multiple pregnancies, which can pose risks to both mother and babies.
- B. Reduced implantation rates due to overcrowding in the uterus.
- C. Improved success rates with no associated risks.
- D. Increased likelihood of genetic abnormalities.
Correct Answer: A
Rationale: The correct answer is A because transferring multiple embryos during IVF increases the likelihood of multiple pregnancies, which can lead to complications for both the mother and babies, such as preterm birth and low birth weight. This is a well-documented risk in IVF procedures.
Choice B is incorrect because overcrowding in the uterus does not reduce implantation rates; rather, it can increase the chances of successful implantation of the embryos.
Choice C is incorrect as transferring multiple embryos does not guarantee improved success rates and can actually increase the risks associated with multiple pregnancies.
Choice D is incorrect because while there is a slightly increased risk of genetic abnormalities in pregnancies resulting from IVF, the primary concern related to transferring multiple embryos is the increased risk of multiple pregnancies.
A provider has ordered several diagnostic procedures for a couple with suspected infertility. Which diagnostic procedure is useful for determining if ovulation has occurred?
- A. FSH level
- B. Progesterone level
- C. Estrogen level
- D. Vaginal ultrasound
Correct Answer: B
Rationale: The correct answer is B: Progesterone level. Progesterone is the hormone secreted after ovulation, indicating that ovulation has occurred. Monitoring progesterone levels can confirm ovulation. FSH (A) and estrogen (C) levels reflect the ovarian function but do not directly confirm ovulation. Vaginal ultrasound (D) can visualize the ovaries but does not definitively confirm ovulation.
