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.
What is the primary goal of using gonadotropins in fertility treatments?
- A. To suppress ovulation for egg preservation.
- B. To stimulate the ovaries to produce multiple eggs.
- C. To prevent hormonal fluctuations during the menstrual cycle.
- D. To enhance uterine lining growth for implantation.
Correct Answer: B
Rationale: The primary goal of using gonadotropins in fertility treatments is to stimulate the ovaries to produce multiple eggs. This increases the chances of successful fertilization and pregnancy. Gonadotropins mimic the natural hormones that regulate ovulation and stimulate the growth of follicles in the ovaries. By producing multiple eggs, there is a higher likelihood of at least one egg being successfully fertilized.
Choice A is incorrect because gonadotropins actually stimulate ovulation rather than suppress it.
Choice C is incorrect as gonadotropins do not prevent hormonal fluctuations but rather help regulate and induce controlled hormonal changes.
Choice D is incorrect as the primary goal of using gonadotropins is not to enhance uterine lining growth but rather to stimulate egg production in the ovaries.
A couple undergoing IVF asks about the role of progesterone injections post-transfer. What is the nurse's best explanation?
- A. Progesterone supports the uterine lining to help maintain a pregnancy.
- B. Progesterone improves egg quality during IVF cycles.
- C. Progesterone prevents the formation of ovarian cysts.
- D. Progesterone reduces the chances of multiple pregnancies.
Correct Answer: A
Rationale: The correct answer is A: Progesterone supports the uterine lining to help maintain a pregnancy post-transfer. Progesterone is crucial in preparing the uterine lining for embryo implantation and supporting early pregnancy. It helps thicken the endometrium, creating a hospitable environment for the embryo to implant and grow. Choice B is incorrect as progesterone does not directly improve egg quality. Choice C is incorrect as progesterone does not prevent ovarian cyst formation. Choice D is incorrect as progesterone does not reduce the chances of multiple pregnancies; in fact, it may slightly increase the risk of multiples in IVF.
What is the significance of basal body temperature (BBT) tracking in fertility?
- A. BBT predicts the exact time of ovulation.
- B. A rise in BBT confirms that ovulation has occurred.
- C. BBT tracking eliminates the need for ovulation predictor kits.
- D. BBT remains constant throughout the menstrual cycle.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. BBT rise confirms ovulation due to increased progesterone post-ovulation.
2. Progesterone causes a slight increase in BBT, signaling the release of an egg.
3. The shift in BBT helps predict the fertile window for conception.
4. BBT tracking does not predict the exact time of ovulation (A), nor eliminate the need for ovulation predictor kits (C), and BBT does not remain constant throughout the cycle (D).
A patient undergoing IVF asks about the role of gonadotropins. What should the nurse explain?
- A. Gonadotropins suppress ovulation to control the cycle.
- B. They stimulate the ovaries to produce multiple eggs for retrieval.
- C. They are only used during natural conception cycles.
- D. Gonadotropins replace progesterone in early pregnancy.
Correct Answer: B
Rationale: The correct answer is B because gonadotropins stimulate the ovaries to produce multiple eggs for retrieval during IVF. This is crucial to increase the chances of successful fertilization. Choice A is incorrect as gonadotropins actually stimulate ovulation. Choice C is incorrect as gonadotropins are specifically used in assisted reproductive technologies like IVF. Choice D is incorrect as gonadotropins do not replace progesterone but rather help in follicular development.
