Question 1 of 5

What is the primary role of progesterone in early pregnancy?

Correct Answer: B

Rationale: The correct answer is B: To maintain the uterine lining for implantation and pregnancy. Progesterone is crucial in early pregnancy as it helps in thickening and maintaining the uterine lining to support implantation of the fertilized egg and sustain the pregnancy. It also plays a role in suppressing the immune response to prevent rejection of the embryo. A: To stimulate fetal development - Incorrect. Progesterone primarily focuses on preparing the uterus for pregnancy rather than directly stimulating fetal development. C: To trigger ovulation and release of the egg - Incorrect. Progesterone is involved in the second half of the menstrual cycle after ovulation has occurred and is not responsible for triggering ovulation. D: To increase the production of amniotic fluid - Incorrect. Progesterone does not directly impact the production of amniotic fluid, which is mainly regulated by the fetal kidneys and placenta.

Question 2 of 5

A patient asks how ovulation predictor kits work. What should the nurse explain?

Correct Answer: B

Rationale: The correct answer is B: Ovulation predictor kits work by detecting the luteinizing hormone (LH) surge in urine. LH surge triggers ovulation within 24-48 hours. This surge can be detected in urine, indicating that ovulation is about to occur. Estrogen levels (A) fluctuate throughout the menstrual cycle but are not directly related to ovulation. Pregnancy confirmation (C) occurs after ovulation and fertilization. Basal body temperature (D) monitoring helps track ovulation patterns but does not predict ovulation directly.

Question 3 of 5

A couple undergoing fertility treatments asks about the impact of age on success rates. What should the nurse explain?

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.

Question 4 of 5

How does lifestyle modification improve male fertility?

Correct Answer: B

Rationale: The correct answer is B because lifestyle modifications such as reducing stress, maintaining a healthy weight, avoiding harmful substances, and exercising can improve male fertility by optimizing overall reproductive health. Stress reduction can positively impact hormone levels and sperm production. Choices A, C, and D are incorrect because lifestyle modifications do not directly guarantee successful fertilization, eliminate the need for medical treatments, or directly improve sperm motility and morphology.

Question 5 of 5

What should the nurse emphasize when discussing healthy BMI and fertility with a patient?

Correct Answer: B

Rationale: The correct answer is B because a BMI within the normal range is associated with improved hormonal balance and ovulation, which are crucial factors for fertility. This is supported by research showing that both underweight and overweight BMI can negatively impact fertility. Choice A is incorrect as BMI does impact fertility outcomes. Choice C is incorrect as BMI plays a role before conception as well. Choice D is incorrect as a low BMI can actually decrease fertility rates due to hormonal imbalances.
