During infertility counseling, the nurse explains the purpose of an HSG (hysterosalpingogram). What is the best explanation?

Correct Answer: B

Rationale: Rationale: The correct answer is B because an HSG is used to visualize the structure and patency of the uterus and fallopian tubes, helping to diagnose causes of infertility such as tubal blockages or abnormalities. A is incorrect because HSG does not assess ovarian function or hormone levels. C is incorrect as HSG does not determine ovulation timing but rather evaluates tubal patency. D is incorrect because HSG is not used to monitor fetal development.

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.

Correct Answer: B

Rationale: The correct answer is B: To trigger the release of mature eggs from the ovary. hCG injections are commonly used in fertility treatments to induce ovulation by mimicking the hormone LH, which triggers the release of mature eggs from the ovary. This is crucial for assisted reproductive techniques like in vitro fertilization. A: Incorrect. hCG injections do not prevent ovulation; instead, they promote it. C: Incorrect. hCG injections do not directly enhance the quality of embryos. D: Incorrect. hCG injections are not used to suppress uterine contractions post-implantation; they are primarily for ovulation induction.
