A nurse is explaining the role of intrauterine insemination (IUI). What should the nurse include?

Correct Answer: A

Rationale: The correct answer is A because intrauterine insemination (IUI) involves placing washed sperm directly into the uterus, increasing the chances of fertilization. This method bypasses potential obstacles in the reproductive tract, aiding sperm in reaching the egg. Choice B is incorrect because IUI is not primarily used to treat structural abnormalities in the uterus but rather to facilitate fertilization. Choice C is incorrect as IUI does not guarantee fertilization since other factors can still affect the success of conception. Choice D is incorrect because ovulation tracking is still important in IUI to ensure optimal timing for the procedure.

Correct Answer: B

Rationale: The correct answer is B: To stimulate the release of an egg from the ovary. LH surge triggers ovulation, releasing the mature egg from the follicle. This is crucial for fertility. A is incorrect because progesterone maintains the uterine lining, not LH. C is incorrect as LH doesn't regulate progesterone during pregnancy, but plays a role in ovulation. D is incorrect as LH and FSH work together to regulate the menstrual cycle, not inhibit each other.

Correct Answer: A

Rationale: The correct answer is A because IUI (Intrauterine Insemination) bypasses the cervix and places sperm directly in the uterus, increasing the chances of sperm reaching the fallopian tubes to fertilize the egg. This method improves the sperm's proximity to the egg, optimizing the chances of conception. The other choices are incorrect because B (enhancing egg quality) is not achieved through IUI, C (eliminating ovulation tracking) is not true as tracking is still necessary for timing the procedure, and D (combining egg and sperm outside the body) describes in vitro fertilization (IVF), not IUI.

Correct Answer: B

Rationale: The correct answer is B: Embryo transfer typically occurs 3 to 5 days after fertilization. This timing aligns with the development of embryos to the blastocyst stage, which is crucial for successful implantation in the uterus. By waiting until this stage, the chances of a successful pregnancy are increased. Choice A is incorrect because embryos do not reach the blastocyst stage on the day of fertilization. Choice C is incorrect as embryo development stage is a key factor in determining the timing of transfer. Choice D is incorrect as waiting until pregnancy is confirmed would delay the transfer unnecessarily.

Correct Answer: B

Rationale: The correct answer is B: Estrogen supports the growth of the uterine lining for implantation. Estrogen plays a key role in the menstrual cycle by stimulating the thickening of the endometrium (uterine lining) to prepare for potential implantation of a fertilized egg. This process occurs during the proliferative phase of the menstrual cycle. Choice A is incorrect because ovulation is primarily triggered by luteinizing hormone (LH) surge, not estrogen. Choice C is incorrect as estrogen levels decrease during pregnancy, allowing ovulation to occur. Choice D is incorrect because while estrogen and progesterone work together in the menstrual cycle, estrogen does not directly regulate progesterone production.
