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.

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.
A patient asks about the benefits of time-lapse embryo monitoring in IVF. What should the nurse highlight?
- A. It guarantees successful implantation of embryos.
- B. It allows continuous observation of embryo development without disturbing the culture environment.
- C. It eliminates the need for hormone support during IVF.
- D. It shortens the time required for fertilization.
Correct Answer: B
Rationale: The correct answer is B because time-lapse embryo monitoring in IVF allows continuous observation of embryo development without disturbing the culture environment. This is crucial as it provides real-time data on embryo growth and helps in selecting the healthiest embryos for transfer. Choice A is incorrect as implantation success is not guaranteed by monitoring alone. Choice C is incorrect as hormone support is still needed in IVF. Choice D is incorrect as time-lapse monitoring does not affect the fertilization process itself.
A nurse is educating a patient about frozen embryo transfer (FET). What should be emphasized?
- A. FET requires daily hormone injections for success.
- B. FET involves transferring previously frozen embryos into the uterus.
- C. FET is only performed if natural conception is impossible.
- D. FET guarantees a successful pregnancy outcome.
Correct Answer: B
Rationale: The correct answer is B: FET involves transferring previously frozen embryos into the uterus. This is because FET is a process where frozen embryos from a previous IVF cycle are thawed and transferred into the uterus. The other choices are incorrect: A is false as hormone injections may not be required daily, C is false as FET can be done for various reasons beyond just natural conception issues, and D is false as success is not guaranteed in any fertility treatment.
During a consultation, a patient asks about egg freezing. What should the nurse emphasize?
- A. Egg freezing is only for women over 35.
- B. The quality of eggs decreases with age, so earlier freezing is recommended.
- C. Frozen eggs can only be used within five years.
- D. Egg freezing eliminates the need for hormonal treatments.
Correct Answer: B
Rationale: The correct answer is B because the quality of eggs decreases with age due to biological factors, making earlier egg freezing more effective. Freezing eggs at a younger age preserves better quality eggs for future use in assisted reproduction techniques. Choice A is incorrect as egg freezing is not limited to women over 35. Choice C is incorrect as frozen eggs can be stored for much longer than five years. Choice D is incorrect because egg freezing does not eliminate the need for hormonal treatments; it simply preserves eggs for future use.
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.
