A nurse is teaching about lifestyle factors that can affect male fertility. Which recommendation is appropriate?

Correct Answer: A

Rationale: The correct answer is A: Limit exposure to high temperatures, such as saunas. High temperatures can negatively impact sperm production and quality by affecting the testes' ability to regulate temperature. Saunas, hot tubs, and hot baths can increase scrotal temperature, leading to decreased sperm count and motility. This recommendation is appropriate as it addresses a known lifestyle factor that can affect male fertility. Summary of why other choices are incorrect: B: Increasing calorie intake does not necessarily boost sperm production. A balanced diet is important for overall health, but excessive calorie intake may lead to obesity, which can negatively impact fertility. C: Using over-the-counter supplements may not always improve sperm quality, and some supplements may have negative effects. It's essential to consult a healthcare provider before taking any supplements. D: Avoiding physical activity is not recommended as moderate exercise is beneficial for overall health and can support sperm production. Physical activity helps maintain a healthy weight, which is important for fertility.

Correct Answer: B

Rationale: The correct answer is B, to assist fertilization by injecting a single sperm directly into an egg. In ICSI, a single sperm is carefully selected and injected into an egg to aid fertilization, particularly in cases of male infertility. This method ensures that fertilization occurs successfully by bypassing natural barriers. Choice A is incorrect as multiple sperm fertilizing an egg can lead to genetic abnormalities. Choice C is incorrect as ovulation is induced before egg retrieval, not during stimulation cycles. Choice D is incorrect as ovarian stimulation is necessary to produce multiple eggs for retrieval.

Correct Answer: B

Rationale: The correct answer is B, to visualize the uterine cavity for abnormalities. A saline sonohysterogram is a diagnostic procedure that involves injecting saline into the uterus and performing an ultrasound to assess the uterine cavity for abnormalities such as polyps, fibroids, or adhesions. This helps in identifying potential causes of infertility related to uterine issues. A: Assessing ovarian function and reserve is typically done through blood tests and ultrasound imaging, not a saline sonohysterogram. C: Monitoring hormone levels in real-time is usually done through blood tests, not imaging procedures like a saline sonohysterogram. D: Detecting genetic abnormalities in embryos is typically done through preimplantation genetic testing or genetic screening, not a saline sonohysterogram.

Correct Answer: B

Rationale: The correct answer is B because maintaining a healthy weight positively affects hormonal balance and sperm quality in both men and women, leading to improved fertility outcomes. This is supported by research showing the link between obesity and infertility. Choice A is incorrect as weight management does impact fertility. Choice C is incorrect as weight loss can benefit fertility in both genders. Choice D is incorrect as being underweight can actually negatively impact fertility in men.

Correct Answer: B

Rationale: The correct answer is B because tubal factor infertility is primarily due to blockages or damage in the fallopian tubes, which can prevent the egg from meeting the sperm for fertilization. Blockages can result from infections, surgeries, or conditions like endometriosis. Choices A, C, and D are incorrect because hormonal imbalances affecting the ovaries, previous infections or surgeries, and impacts on natural conception are not the primary causes of tubal factor infertility.
