During IVF, a patient asks about the role of estrogen in preparing for embryo transfer. What should the nurse explain?
- A. Estrogen helps regulate ovarian stimulation protocols.
- B. Estrogen thickens the uterine lining, creating a supportive environment for implantation.
- C. Estrogen prevents premature ovulation during stimulation cycles.
- D. Estrogen eliminates the need for progesterone support post-transfer.
Correct Answer: B
Rationale: The correct answer is B because estrogen plays a crucial role in thickening the uterine lining, creating a supportive environment for embryo implantation during IVF. This is essential for successful pregnancy. Estrogen does not directly regulate ovarian stimulation protocols (choice A), prevent premature ovulation (choice C), or eliminate the need for progesterone support post-transfer (choice D). Estrogen primarily focuses on preparing the uterus for implantation rather than affecting other aspects of the IVF process.

A woman is informed that she is a carrier for Tay-Sachs disease, an autosomal recessive illness. What is her phenotype?
- A. She has one recessive gene and one normal gene.
- B. She has two recessive genes.
- C. She exhibits all symptoms of the disease.
- D. She exhibits no symptoms of the disease.
Correct Answer: D
Rationale: Carriers of autosomal recessive diseases do not exhibit symptoms.
What is the significance of basal body temperature (BBT) tracking in fertility?
- A. BBT predicts the exact time of ovulation.
- B. A rise in BBT confirms that ovulation has occurred.
- C. BBT tracking eliminates the need for ovulation predictor kits.
- D. BBT remains constant throughout the menstrual cycle.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. BBT rise confirms ovulation due to increased progesterone post-ovulation.
2. Progesterone causes a slight increase in BBT, signaling the release of an egg.
3. The shift in BBT helps predict the fertile window for conception.
4. BBT tracking does not predict the exact time of ovulation (A), nor eliminate the need for ovulation predictor kits (C), and BBT does not remain constant throughout the cycle (D).
A patient undergoing infertility treatment asks about the importance of stress management. What should the nurse explain?
- A. Stress has no impact on fertility treatment outcomes.
- B. Stress can negatively affect hormone levels and ovulation.
- C. Managing stress is only important after conception occurs.
- D. Stress is a common cause of infertility in both partners.
Correct Answer: B
Rationale: The correct answer is B because stress can indeed negatively affect hormone levels and ovulation, thereby impacting fertility treatment outcomes. High levels of stress can disrupt the delicate balance of hormones involved in the reproductive process, leading to irregular ovulation and potentially hindering conception. It is essential for patients undergoing infertility treatment to manage stress effectively to optimize their chances of success.
Choice A is incorrect because research suggests that stress can impact fertility treatment outcomes. Choice C is incorrect as stress management is important throughout the fertility treatment process, not just after conception. Choice D is incorrect because while stress can contribute to infertility, it is not always the primary cause and can affect fertility differently in each partner.
A woman asks the nurse, 'My nuchal fold scan results were abnormal. What does that mean?' Which of the following comments is appropriate for the nurse to make at this time?
- A. I am sorry to tell you that your baby will be born with a serious deformity.
- B. The results show that your child will have cri du chat syndrome.
- C. The test is done to see if you are high risk for preterm labor.
- D. An abnormal test indicates that your baby may have Down syndrome.
Correct Answer: D
Rationale: Abnormal nuchal fold scans can indicate chromosomal abnormalities like Down syndrome.
A patient asks for advice regarding whether to have children in the future after hearing she is a carrier for an autosomal-recessive disorder. What is the nurse's best response?
- A. Encourage the patient to avoid having children as the risk of having a child with a disorder is 50%.
- B. Explain that if the patient proceeds with a pregnancy, her risk of having a child with a disorder is 25% because she is only a carrier.
- C. Encourage the patient to pursue pregnancy, informing her that she can always terminate a pregnancy if the fetus is found to be affected.
- D. Ask the patient to describe her feelings about potentially having an affected infant.
Correct Answer: D
Rationale: The correct answer is D because it demonstrates empathy, promotes open communication, and supports patient autonomy. By asking the patient to describe her feelings, the nurse can understand her emotional state, values, and beliefs, which are crucial in decision-making. This approach encourages shared decision-making and allows the nurse to provide individualized support.
Choice A is incorrect because it is overly deterministic and does not consider individual circumstances. Choice B is incorrect as it simplifies the genetic risk calculation and overlooks the emotional aspect of decision-making. Choice C is incorrect as it may not respect the patient's autonomy and fails to address the emotional and ethical complexities involved in such a decision.
