What is the purpose of using a GnRH antagonist in fertility treatments?
- A. To trigger ovulation directly.
- B. To prevent premature ovulation during controlled ovarian stimulation.
- C. To stimulate the growth of the uterine lining.
- D. To improve egg quality in natural cycles.
Correct Answer: B
Rationale: The purpose of using a GnRH antagonist in fertility treatments is to prevent premature ovulation during controlled ovarian stimulation. GnRH antagonists work by blocking the release of luteinizing hormone (LH), which can trigger premature ovulation. This allows for better control of the timing of ovulation in assisted reproductive techniques.
Choice A is incorrect because GnRH antagonists do not trigger ovulation directly; they prevent it. Choice C is incorrect because stimulating the growth of the uterine lining is typically achieved through other medications like estrogen. Choice D is incorrect because GnRH antagonists do not directly improve egg quality; they primarily target ovulation timing.

The nurse in a genetic clinic interviews a couple and develops a pedigree chart. Which inheritance patterns does the pedigree chart portray?
- A. Autosomal recessive
- B. X-linked recessive
- C. Autosomal dominant
- D. X-linked dominant
Correct Answer: C
Rationale: The correct answer is C, Autosomal dominant. In an autosomal dominant inheritance pattern, the trait is passed down from generation to generation, affecting both males and females equally. This is indicated by the presence of the trait in every generation of the pedigree chart. In contrast, autosomal recessive traits would skip generations and require both parents to be carriers. X-linked recessive traits mainly affect males and skip generations. X-linked dominant traits would be present in every generation but would affect more females than males.
During infertility counseling, the nurse explains the purpose of an HSG (hysterosalpingogram). What is the best explanation?
- A. It evaluates ovarian function and hormone levels.
- B. It assesses the structure and patency of the uterus and fallopian tubes.
- C. It determines the timing of ovulation for insemination.
- D. It monitors fetal development during early pregnancy.
Correct Answer: B
Rationale: Rationale: The correct answer is B because an HSG is used to visualize the structure and patency of the uterus and fallopian tubes, helping to diagnose causes of infertility such as tubal blockages or abnormalities. A is incorrect because HSG does not assess ovarian function or hormone levels. C is incorrect as HSG does not determine ovulation timing but rather evaluates tubal patency. D is incorrect because HSG is not used to monitor fetal development.
During preconception counseling, a patient asks about the impact of caffeine on fertility. What should the nurse emphasize?
- A. Moderate caffeine intake is generally considered safe.
- B. Caffeine improves ovulation and increases conception chances.
- C. All caffeine should be eliminated to conceive successfully.
- D. Caffeine intake only affects male fertility.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Moderate caffeine intake is generally considered safe during preconception as excessive intake may affect fertility.
2. Studies show that moderate caffeine consumption doesn't significantly impact fertility.
3. Advising complete elimination may be overly restrictive and challenging for patients.
4. Caffeine can affect both male and female fertility, not just male fertility.
5. Emphasizing moderation allows for informed decision-making and realistic lifestyle changes.
Summary of other choices:
B: Incorrect - Caffeine does not improve ovulation or increase conception chances.
C: Incorrect - Complete elimination of caffeine is unnecessary for successful conception.
D: Incorrect - Caffeine intake can affect both male and female fertility, not limited to male fertility.
A nurse is offering preconception counseling to a couple. What advice should be emphasized to support fertility?
- A. Smoking cessation improves both male and female fertility.
- B. Caffeine intake has no impact on fertility.
- C. Stress management is unnecessary if ovulation occurs regularly.
- D. High protein diets guarantee improved egg quality.
Correct Answer: A
Rationale: The correct answer is A: Smoking cessation improves both male and female fertility. Smoking negatively impacts fertility by reducing sperm quality, disrupting hormone production, and affecting egg quality. By quitting smoking, both partners can improve their chances of conceiving.
Summary:
B: Caffeine intake can affect fertility, so moderate consumption is recommended.
C: Stress management is important for fertility, as stress can disrupt hormonal balance.
D: High protein diets alone do not guarantee improved egg quality; a balanced diet is essential for fertility.
A nurse is providing care to a woman in labor. After assessment of the fetus, the nurse documents the fetal lie. Which term would the nurse use?
- A. flexion
- B. extension
- C. longitudinal
- D. cephalic
Correct Answer: C
Rationale: The correct answer is C because fetal lie refers to the relationship of the long axis of the fetus to the long axis of the mother. The primary lies are longitudinal, oblique, and transverse. Flexion and extension are terms used to describe fetal attitude, while cephalic is used to describe fetal presentation.
