A nurse is explaining genetic testing options before conception. What should be included?
- A. Genetic testing guarantees a successful pregnancy.
- B. It identifies potential genetic conditions that could affect the baby.
- C. It eliminates the need for other prenatal tests.
- D. Genetic testing is only available during pregnancy.
Correct Answer: B
Rationale: The correct answer is B because genetic testing before conception can identify potential genetic conditions that could affect the baby, enabling parents to make informed decisions. This information helps in understanding the risk of passing on genetic disorders and allows for options like genetic counseling or assisted reproductive technologies. Choice A is incorrect because genetic testing does not guarantee a successful pregnancy. Choice C is incorrect as other prenatal tests may still be necessary. Choice D is incorrect as genetic testing can be done before conception as well.

A patient asks about the effects of environmental toxins on fertility. What should the nurse explain?
- A. Environmental toxins have no impact on fertility outcomes.
- B. Exposure to toxins can harm egg and sperm quality, reducing fertility.
- C. Toxins only affect fertility in individuals over 40.
- D. Avoiding toxins guarantees immediate conception.
Correct Answer: B
Rationale: The correct answer is B because exposure to environmental toxins can indeed harm egg and sperm quality, leading to reduced fertility. Toxins can disrupt hormone balance, affect reproductive organs, and damage genetic material in eggs and sperm. This can result in difficulty conceiving or increased risk of miscarriage. Choices A, C, and D are incorrect. A is inaccurate as environmental toxins can impact fertility outcomes. C is incorrect as toxins can affect fertility at any age. D is misleading as avoiding toxins does not guarantee immediate conception, as fertility is influenced by various factors.
The nurse is reviewing the medical record of a woman in labor and notes that the fetal position is documented as LSA. The nurse interprets this information as indicating which part as the presenting part?
- A. occiput
- B. face
- C. buttocks
- D. shoulder
Correct Answer: C
Rationale: The correct answer is C because in the notation LSA, the S denotes the sacrum or buttocks as the presenting part. The occiput is denoted by O, face by M, and shoulder by A.
A woman is seeking genetic counseling during her pregnancy. She has a strong family history of diabetes mellitus. She wishes to have an amniocentesis to determine whether she is carrying a baby who will 'develop diabetes.' Which of the following replies would be most appropriate for the nurse to make?
- A. Doctors don't do amniocenteses to detect diabetes.
- B. Diabetes cannot be diagnosed by looking at the genes.
- C. Although diabetes does have a genetic component
- D. diet and exercise also determine whether or not someone is diabetic.
Correct Answer: C
Rationale: Diabetes involves genetic and environmental factors.
During a genetic evaluation, it is discovered that the woman is carrying one autosomal dominant gene for a serious late adult–onset disease, while her partner's history is unremarkable. Based on this information, which of the following family members should be considered high risk and in need of genetic counseling? Select all that apply.
- A. The woman's fetus.
- B. The woman's sisters.
- C. The woman's brothers.
- D. The woman's parents.
Correct Answer: A
Rationale: All first-degree relatives and offspring are at risk for inheriting the gene.
What is the significance of timing in intrauterine insemination (IUI)?
- A. IUI is effective regardless of ovulation timing.
- B. IUI must be timed closely with ovulation for optimal success.
- C. IUI should only be done after the implantation window opens.
- D. Timing is irrelevant as long as sperm quality is high.
Correct Answer: B
Rationale: The correct answer is B because timing is crucial in IUI to increase the chance of fertilization. Intrauterine insemination must be done close to ovulation to ensure that the sperm meets the egg for successful conception. Timing is essential to maximize the chances of successful fertilization.
Choice A is incorrect because timing is indeed important for the success of IUI. Choice C is incorrect because the implantation window is not related to the timing of IUI. Choice D is incorrect because high sperm quality alone is not sufficient for successful IUI; timing is a critical factor in achieving pregnancy through IUI.
