A couple undergoing IVF asks about the role of progesterone injections post-transfer. What is the nurse's best explanation?

Correct Answer: A

Rationale: The correct answer is A: Progesterone supports the uterine lining to help maintain a pregnancy post-transfer. Progesterone is crucial in preparing the uterine lining for embryo implantation and supporting early pregnancy. It helps thicken the endometrium, creating a hospitable environment for the embryo to implant and grow. Choice B is incorrect as progesterone does not directly improve egg quality. Choice C is incorrect as progesterone does not prevent ovarian cyst formation. Choice D is incorrect as progesterone does not reduce the chances of multiple pregnancies; in fact, it may slightly increase the risk of multiples in IVF.

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.

Correct Answer: B

Rationale: The correct answer is B: In-vitro fertilization (IVF). In IVF, eggs are retrieved from the ovaries and fertilized with sperm in a laboratory dish. This method involves fertilization outside the body, making it the correct choice. A: Intrauterine insemination (IUI) involves placing washed sperm directly into the uterus, not fertilizing eggs outside the body. C: Ovarian stimulation is a process to stimulate the ovaries to produce multiple eggs but does not involve fertilization outside the body. D: Egg freezing is a method where eggs are frozen for future use but does not involve fertilization outside the body.

Correct Answer: B

Rationale: The correct answer is B because the quality of eggs decreases with age due to biological factors, making earlier egg freezing more effective. Freezing eggs at a younger age preserves better quality eggs for future use in assisted reproduction techniques. Choice A is incorrect as egg freezing is not limited to women over 35. Choice C is incorrect as frozen eggs can be stored for much longer than five years. Choice D is incorrect because egg freezing does not eliminate the need for hormonal treatments; it simply preserves eggs for future use.

Correct Answer: B

Rationale: The primary goal of using gonadotropins in fertility treatments is to stimulate the ovaries to produce multiple eggs. This increases the chances of successful fertilization and pregnancy. Gonadotropins mimic the natural hormones that regulate ovulation and stimulate the growth of follicles in the ovaries. By producing multiple eggs, there is a higher likelihood of at least one egg being successfully fertilized. Choice A is incorrect because gonadotropins actually stimulate ovulation rather than suppress it. Choice C is incorrect as gonadotropins do not prevent hormonal fluctuations but rather help regulate and induce controlled hormonal changes. Choice D is incorrect as the primary goal of using gonadotropins is not to enhance uterine lining growth but rather to stimulate egg production in the ovaries.
