A patient undergoing IUI asks how the procedure increases the chances of conception. What should the nurse explain?

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: 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.

Correct Answer: B

Rationale: The correct answer is B because genetic testing before conception can identify potential genetic conditions that could affect the baby, enabling parents to make informed decisions. This information helps in understanding the risk of passing on genetic disorders and allows for options like genetic counseling or assisted reproductive technologies. Choice A is incorrect because genetic testing does not guarantee a successful pregnancy. Choice C is incorrect as other prenatal tests may still be necessary. Choice D is incorrect as genetic testing can be done before conception as well.

Correct Answer: B

Rationale: The correct answer is B because both a balanced diet and regular moderate exercise support reproductive health. A balanced diet provides essential nutrients for fertility, while exercise helps regulate hormones and improve overall health, increasing chances of conception. Choice A is incorrect because exercise plays a crucial role in fertility. Choice C is incorrect as weight gain should be based on individual needs, not a general recommendation. Choice D is incorrect as stress management is important for fertility as stress can impact hormone levels and ovulation.

Correct Answer: B

Rationale: The correct answer is B: It supports hormonal balance and may improve egg quality and implantation rates. Vitamin D plays a crucial role in reproductive health by supporting hormonal balance, which is essential for the regulation of menstrual cycles and overall reproductive function. Additionally, adequate levels of vitamin D have been associated with improved egg quality and increased success rates of implantation during conception. Incorrect choices: A: Vitamin D is necessary throughout pregnancy, not just during the third trimester. C: Prevention of neural tube defects is mainly linked to folic acid intake, not vitamin D. D: Vitamin D is important for overall health, but it does not eliminate the need for other essential prenatal vitamins that provide a variety of nutrients necessary for a healthy pregnancy.
