What is the purpose of progesterone in supporting early pregnancy?
- A. To increase fetal growth rates.
- B. To maintain the uterine lining and prevent menstrual shedding.
- C. To stimulate ovulation during the menstrual cycle.
- D. To regulate the release of other reproductive hormones.
Correct Answer: B
Rationale: The correct answer is B because progesterone plays a crucial role in maintaining the uterine lining to support implantation and prevent menstrual shedding. Progesterone prepares the uterus for the potential implantation of a fertilized egg by thickening the endometrium. If fertilization occurs, progesterone continues to support the pregnancy by ensuring the uterine lining remains intact to provide a nurturing environment for the developing embryo. Choices A, C, and D are incorrect because progesterone's main function in early pregnancy is not to increase fetal growth rates, stimulate ovulation, or regulate the release of other reproductive hormones.

The nurse is instructing a client on taking her basal body temperature. What is the primary purpose of this test?
- A. To determine if the client's cervical mucus contains enough estrogen to support sperm motility.
- B. To identify if the client's temperature rises 1 to 5 days after midcycle.
- C. To assess whether surgical correction of uterine pathology is needed.
- D. To identify if the client is experiencing blockage of the uterine cavity and fallopian tubes.
Correct Answer: B
Rationale: Rationale: The correct answer is B because basal body temperature rises 1 to 5 days after midcycle, indicating ovulation. This helps determine the client's most fertile period for conception. Choice A is incorrect as basal body temperature does not assess cervical mucus. Choice C is incorrect as it does not evaluate uterine pathology. Choice D is incorrect as basal body temperature does not assess blockage of uterine cavity or fallopian tubes.
A 44-year-old woman presents with an unexpected pregnancy. She asks the nurse, 'Is my baby going to have a birth defect? My third cousin has Down syndrome.' What is the nurse's best response?
- A. Tell the patient she is at risk for gene mutation because a birth defect in a distant relative places the woman at increased risk.
- B. Discuss the potential risk for intrauterine growth retardation due to the mother's advanced age.
- C. Discuss the patient's situation with the physician to ask for a referral to high-risk obstetrics.
- D. Discuss the potential risk for a chromosomal abnormality based on the patient's advanced age.
Correct Answer: D
Rationale: Step 1: The correct answer is D because advanced maternal age (AMA), generally defined as 35 years or older, is a well-known risk factor for chromosomal abnormalities, such as Down syndrome.
Step 2: Down syndrome is more common in babies born to mothers over the age of 35 due to the increased likelihood of errors in cell division during egg development.
Step 3: Given the patient's age of 44, she falls into the category of AMA and is at an increased risk for chromosomal abnormalities in her baby.
Step 4: Option A is incorrect as the risk is not solely based on gene mutation but rather on the increased chance of chromosomal abnormalities due to age.
Step 5: Option B is incorrect as it focuses on intrauterine growth retardation, which is not directly related to the patient's query about birth defects.
Step 6: Option C is incorrect as a referral to high-risk obstetrics may not be necessary solely based on the patient's
During ovulation induction, a patient asks why hormone levels are monitored so frequently. What is the nurse's best response?
- A. To predict embryo quality before fertilization.
- B. To ensure hormone levels stay within safe and effective ranges for egg maturation.
- C. To confirm the patient is pregnant before the cycle ends.
- D. To determine if the uterine lining is ready for implantation.
Correct Answer: B
Rationale: The correct answer is B. Monitoring hormone levels during ovulation induction is essential to ensure that the hormones stay within safe and effective ranges for successful egg maturation. By closely monitoring hormone levels, healthcare providers can adjust medication dosages as needed to optimize the chances of successful ovulation. This helps to minimize the risk of overstimulation or understimulation of the ovaries, which can impact the quality of the eggs produced.
A: Predicting embryo quality before fertilization is not the primary purpose of monitoring hormone levels during ovulation induction.
C: Confirming pregnancy before the cycle ends is not the purpose of hormone level monitoring during ovulation induction.
D: Determining if the uterine lining is ready for implantation is important, but this is typically assessed through other methods such as ultrasound rather than hormone level monitoring.
A Roman Catholic couple is infertile. Their health care practitioner advises them that their best chance of getting pregnant is via in vitro fertilization with a mixture of the man's sperm and donor sperm. Which of the following issues, related to this procedure, should the nurse realize may be in conflict with the couple's religious beliefs? Select all that apply.
- A. The man will ejaculate by masturbation into a specially designed condom.
- B. The woman may become pregnant with donor sperm.
- C. Fertilization is occurring in the artificial environment of the laboratory.
- D. More embryos will be created than will be used to inseminate the woman.
Correct Answer: A
Rationale: These aspects of IVF conflict with Roman Catholic teachings on procreation and the sanctity of life.
What is the primary purpose of cryopreservation in fertility treatments?
- A. To store embryos, eggs, or sperm for future use.
- B. To improve the success rates of natural conception.
- C. To reduce the need for fertility medications.
- D. To eliminate genetic abnormalities in embryos.
Correct Answer: A
Rationale: The correct answer is A because cryopreservation allows embryos, eggs, or sperm to be stored for future use, preserving fertility options for patients undergoing fertility treatments. This helps in cases like preserving fertility before undergoing treatments that may affect fertility or for those who wish to postpone childbearing.
Choice B is incorrect because cryopreservation doesn't directly improve natural conception rates. Choice C is incorrect as cryopreservation doesn't reduce the need for fertility medications but rather provides a method to store reproductive materials. Choice D is incorrect as cryopreservation doesn't eliminate genetic abnormalities in embryos; it preserves them for potential future use.
