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.

The procedure in which ova are removed by laparoscopy, mixed with sperm, and the embryo(s) returned to the woman's uterus is
- A. in vitro fertilization (IVF).
- B. tubal embryo transfer (TET).
- C. therapeutic insemination (IUI).
- D. gamete intrafallopian transfer (GIFT).
Correct Answer: A
Rationale: The correct answer is A: in vitro fertilization (IVF). In IVF, ova are retrieved via laparoscopy, fertilized with sperm in a lab dish, and then the resulting embryo(s) are transferred back to the woman's uterus. This process allows for fertilization to occur outside the body.
Incorrect choices:
B: Tubal embryo transfer (TET) involves transferring embryos directly into the fallopian tubes, not the uterus.
C: Therapeutic insemination (IUI) is the process of injecting sperm directly into the uterus, not involving the removal and fertilization of ova.
D: Gamete intrafallopian transfer (GIFT) involves transferring both eggs and sperm into the fallopian tubes for fertilization to occur internally, not in a lab dish.
A client's amniocentesis results were reported as 46, XY. Her obstetrician informed her at the time that everything 'looks good.' Shortly after birth the baby is diagnosed with cerebral palsy. Which of the following responses will explain this result?
- A. It is likely that the client received the wrong amniocentesis results.
- B. Cerebral palsy is not a genetic disease.
- C. The genes that cause cerebral palsy have not yet been discovered.
- D. The genetics lab failed to test for cerebral palsy.
Correct Answer: B
Rationale: Cerebral palsy is not typically caused by genetic factors.
A nurse is instructing a woman on the use of ovulation predictor kits. What should the nurse tell the client?
- A. A prescription is required.
- B. The kit will determine a serum LH level.
- C. The LH surge usually occurs 12 hours prior to ovulation.
- D. Your interval of greatest fertility is on the day of the LH surge and the following 2 days.
Correct Answer: D
Rationale: The correct answer is D because the interval of greatest fertility is indeed on the day of the LH surge and the following 2 days, maximizing chances of conception. Choice A is incorrect as ovulation predictor kits are typically over-the-counter. Choice B is incorrect as the kit measures urinary LH, not serum. Choice C is incorrect as the LH surge usually occurs 24-36 hours before ovulation, not 12.
The nurse is analyzing the pedigree shown below. How should the nurse interpret the genotype of the individual in location II-4?

Correct Answer: A
Rationale: The symbol indicates an affected male.
A nurse is counseling a couple on lifestyle modifications to improve fertility. Which recommendation is most appropriate?
- A. Increase caffeine intake for better energy.
- B. Maintain a healthy weight and avoid smoking.
- C. Engage in intensive daily exercise.
- D. Focus solely on timing of intercourse.
Correct Answer: B
Rationale: The correct answer is B: Maintain a healthy weight and avoid smoking. This recommendation is most appropriate because both factors significantly impact fertility. Being at a healthy weight improves hormonal balance and ovulation, while smoking can harm sperm quality and reduce fertility.
Explanation for why other choices are incorrect:
A: Increasing caffeine intake may negatively affect fertility, as high levels of caffeine have been linked to reduced fertility in both men and women.
C: Engaging in intensive daily exercise can actually disrupt menstrual cycles and ovulation, negatively impacting fertility.
D: Focusing solely on timing of intercourse overlooks the importance of overall lifestyle factors that can affect fertility, such as diet, weight, and smoking.
