What is the role of hCG in early pregnancy tests?
- A. hCG stimulates ovulation during the menstrual cycle.
- B. hCG levels rise after implantation, confirming pregnancy.
- C. hCG reduces the risk of miscarriage during early pregnancy.
- D. hCG suppresses the menstrual cycle during pregnancy.
Correct Answer: B
Rationale: The correct answer is B because hCG (human chorionic gonadotropin) levels rise after implantation of the fertilized egg in the uterus, confirming pregnancy. This hormone is produced by the developing placenta and is the key marker used in early pregnancy tests to detect pregnancy.
A is incorrect because hCG does not stimulate ovulation; rather, it is produced after ovulation to support pregnancy.
C is incorrect because while hCG plays a role in supporting pregnancy, it does not directly reduce the risk of miscarriage.
D is incorrect because hCG does not suppress the menstrual cycle; it is actually produced during pregnancy and is essential for maintaining the pregnancy.

What is the purpose of endometrial biopsy in fertility evaluations?
- A. To determine ovarian reserve and egg quality.
- B. To assess the receptivity of the uterine lining for implantation.
- C. To measure hormone levels in the bloodstream.
- D. To monitor embryo development after IVF.
Correct Answer: B
Rationale: The correct answer is B: To assess the receptivity of the uterine lining for implantation. Endometrial biopsy is performed to evaluate the quality of the uterine lining and its ability to support embryo implantation. By examining the endometrial tissue, doctors can assess factors such as thickness, pattern, and receptivity, crucial for successful implantation and pregnancy.
Incorrect choices:
A: To determine ovarian reserve and egg quality - Endometrial biopsy does not provide information on ovarian reserve or egg quality.
C: To measure hormone levels in the bloodstream - Endometrial biopsy does not measure hormone levels in the bloodstream; instead, it focuses on the uterine lining.
D: To monitor embryo development after IVF - Endometrial biopsy is not used to monitor embryo development; it is primarily for assessing uterine receptivity.
A woman who is undergoing infertility testing states, "My husband won't discuss this with me. I don't think he cares about or wants a baby." The nurse's ideal response is
- A. "You should confront him about this."
- B. "He probably doesn't understand your concern."
- C. "Men are sometimes less eager to have children."
- D. "It may be harder for him to express his feelings."
Correct Answer: D
Rationale: The correct answer is D because it acknowledges the husband's potential difficulty in expressing his feelings, validating the woman's concerns while also offering empathy. It is important to recognize that discussing infertility can be emotionally challenging for both partners, and the response shows understanding and support.
Choice A is incorrect as it suggests confrontation, which may escalate the situation and lead to further communication breakdown. Choice B implies a lack of understanding on the husband's part, which may not be the case. Choice C is a generalization and may not address the specific dynamics of this couple's situation.
A patient undergoing ovulation induction asks about the risks involved. What should the nurse include in the discussion?
- A. There are no risks associated with ovulation induction.
- B. The most common risk is ovarian hyperstimulation syndrome (OHSS).
- C. Ovulation induction reduces the chances of natural conception.
- D. Risks only occur with injectable medications.
Correct Answer: B
Rationale: The correct answer is B: The most common risk is ovarian hyperstimulation syndrome (OHSS). This is because during ovulation induction, there is a risk of overstimulating the ovaries, leading to OHSS. This condition can cause abdominal pain, bloating, and in severe cases, fluid accumulation in the abdomen and chest. Other choices are incorrect: A is false as there are risks associated with ovulation induction. C is incorrect because ovulation induction actually increases the chances of conception. D is incorrect as risks can also occur with oral medications, not just injectables.
A nurse is educating a group about male infertility. What factor is most likely to affect sperm quality?
- A. Frequent exercise
- B. Use of mobile phones
- C. Exposure to high temperatures
- D. Dietary habits
Correct Answer: C
Rationale: The correct answer is C, exposure to high temperatures. Sperm quality can be significantly affected by high temperatures as heat can damage sperm production. Elevated scrotal temperatures can impair sperm production and motility. Frequent exercise (choice A) is generally beneficial for overall health, including reproductive function. The use of mobile phones (choice B) has not been definitively linked to male infertility. Dietary habits (choice D) can influence overall health but are not as directly linked to sperm quality as exposure to high temperatures.
A nurse is teaching a couple about the benefits of IVF. Which statement is accurate?
- A. IVF has a 100% success rate for all couples.
- B. IVF allows for genetic testing of embryos before transfer.
- C. IVF eliminates the need for hormonal injections.
- D. IVF can be performed without any fertility medications.
Correct Answer: B
Rationale: The correct answer is B because IVF allows for genetic testing of embryos before transfer, enabling couples to screen for genetic disorders and select healthy embryos. This statement is accurate as genetic testing is a crucial benefit of IVF. The other choices are incorrect because: A is incorrect as IVF success rates vary and are not 100%; C is incorrect as hormonal injections are often necessary in IVF to stimulate egg production; D is incorrect as fertility medications are commonly used to prepare the body for IVF procedures.
