How does weight management affect fertility in both men and women?
- A. It has no impact on fertility outcomes.
- B. Maintaining a healthy weight improves hormonal balance and sperm quality.
- C. Weight loss is only beneficial for women trying to conceive.
- D. Being underweight enhances fertility in men.
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.

What is the purpose of a saline sonohysterogram in infertility evaluation?
- A. To assess ovarian function and reserve.
- B. To visualize the uterine cavity for abnormalities.
- C. To monitor hormone levels in real-time.
- D. To detect genetic abnormalities in embryos.
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.
A nurse is teaching about lifestyle factors that can affect male fertility. Which recommendation is appropriate?
- A. Limit exposure to high temperatures, such as saunas.
- B. Increase calorie intake to boost sperm production.
- C. Use over-the-counter supplements to improve sperm quality.
- D. Avoid physical activity to conserve energy for reproduction.
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.
A woman in her 40th week of pregnancy calls the nurse at the clinic and says she is not sure whether she is in true or false labor. Which statement by the client would lead the nurse to suspect that the woman is experiencing false labor?
- A. I'm feeling contractions mostly in my back.
- B. My contractions are about 6 minutes apart and regular.
- C. The contractions slow down when I walk around.
- D. If I try to talk to my partner during a contraction, I can't.
Correct Answer: C
Rationale: The statement The contractions slow down when I walk around indicates that the contractions are irregular and weak, which is characteristic of false labor. In true labor, contractions are regular, strong, and do not slow down with movement.
A couple undergoing fertility treatments asks about the impact of age on success rates. What should the nurse explain?
- A. Success rates remain constant regardless of age.
- B. Younger age is associated with higher success rates for most treatments.
- C. Male age does not impact fertility treatment outcomes.
- D. Age only matters if the woman is over 50.
Correct Answer: B
Rationale: The correct answer is B because younger age is generally associated with higher success rates in fertility treatments due to factors like better egg quality and ovarian reserve. Older women may have lower success rates due to decreased egg quality and quantity. Choice A is incorrect as success rates do vary with age. Choice C is incorrect because male age can impact fertility treatment outcomes. Choice D is incorrect as age can impact fertility treatment outcomes for women younger than 50 as well.
A 3-month-old baby has been diagnosed with cystic fibrosis (CF). The mother says, 'How could this happen? I had an amniocentesis during my pregnancy and everything was supposed to be normal!' What must the nurse understand about this situation?
- A. Cystic fibrosis cannot be diagnosed by amniocentesis.
- B. The baby may have an uncommon genetic variant of the disease.
- C. It is possible that the laboratory technician made an error.
- D. Instead of obtaining fetal cells the doctor probably harvested maternal cells.
Correct Answer: B
Rationale: Uncommon genetic variants of CF may not be detected by standard testing.
