During IVF, a patient asks about the role of estrogen in preparing for embryo transfer. What should the nurse explain?

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.

Correct Answer: B

Rationale: The correct answer is B because time-lapse embryo monitoring in IVF allows continuous observation of embryo development without disturbing the culture environment. This is crucial as it provides real-time data on embryo growth and helps in selecting the healthiest embryos for transfer. Choice A is incorrect as implantation success is not guaranteed by monitoring alone. Choice C is incorrect as hormone support is still needed in IVF. Choice D is incorrect as time-lapse monitoring does not affect the fertilization process itself.

Correct Answer: B

Rationale: The purpose of ovarian reserve testing in fertility assessments is to estimate the quantity and quality of a woman's remaining eggs. This is crucial in determining a woman's fertility potential and likelihood of success with fertility treatments. By assessing ovarian reserve, healthcare providers can gauge how many eggs a woman has left and how well they are likely to respond to fertility treatments such as in vitro fertilization (IVF). This information is essential for personalized fertility planning. Choices A, C, and D are incorrect as they do not directly relate to the main purpose of ovarian reserve testing, which is specifically focused on evaluating a woman's egg quantity and quality.

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).

Correct Answer: B

Rationale: The correct answer is B: It becomes clear and stretchy during ovulation, indicating peak fertility. Cervical mucus changes during the menstrual cycle are important as they reflect the hormonal changes that occur. During ovulation, cervical mucus becomes clear, watery, and stretchy, resembling egg whites. This type of mucus promotes sperm survival and motility, indicating the most fertile period for conception. The other choices are incorrect because cervical mucus changes do not confirm pregnancy (A), are indeed relevant to fertility (C), and do not only occur after ovulation but actually signal peak fertility during ovulation (D).
