A patient asks about the effectiveness of tracking ovulation using basal body temperature (BBT). What is the nurse's best response?

Correct Answer: B

Rationale: The correct answer is B: BBT is used to confirm ovulation after it occurs. BBT tracking helps confirm ovulation by observing a slight increase in temperature after ovulation. It does not predict ovulation accurately. Choice A is incorrect because BBT is not the most accurate method for predicting ovulation. Choice C is incorrect as BBT tracking can be effective in women of all ages. Choice D is incorrect as BBT tracking is just one method and may not replace other fertility tests.

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.

Correct Answer: A

Rationale: The correct answer is A because cryopreservation allows embryos, eggs, or sperm to be stored for future use, preserving fertility options for patients undergoing fertility treatments. This helps in cases like preserving fertility before undergoing treatments that may affect fertility or for those who wish to postpone childbearing. Choice B is incorrect because cryopreservation doesn't directly improve natural conception rates. Choice C is incorrect as cryopreservation doesn't reduce the need for fertility medications but rather provides a method to store reproductive materials. Choice D is incorrect as cryopreservation doesn't eliminate genetic abnormalities in embryos; it preserves them for potential future use.

Correct Answer: B

Rationale: The correct answer is B because endometriosis can lead to scarring in the reproductive organs and reduce ovarian function, affecting fertility. Scarring can block the fallopian tubes, impairing egg and sperm transport. Reduced ovarian function can affect egg quality and quantity. Choices A, C, and D are incorrect. Endometriosis does not improve natural conception chances; it is a leading cause of infertility. It is related to infertility due to its impact on reproductive organs. Endometriosis often necessitates fertility treatments due to its effects on fertility.

Correct Answer: B

Rationale: The correct answer is B, as pelvic ultrasound allows visualization of uterine and ovarian structures. This is essential in assessing conditions like fibroids, polyps, ovarian cysts, and structural abnormalities that may affect fertility. Ovarian reserve evaluation (A) involves separate tests like AMH levels. Hormone levels (C) are typically measured through blood tests. Genetic abnormalities in embryos (D) are usually identified through preimplantation genetic testing, not pelvic ultrasound.
