A nurse is instructing a patient on the role of folic acid in preconception care. What is the correct explanation?
- A. Folic acid prevents iron deficiency anemia in pregnancy.
- B. Folic acid reduces the risk of neural tube defects in the fetus.
- C. Folic acid is only necessary during the first trimester of pregnancy.
- D. Folic acid enhances the absorption of calcium and vitamin D.
Correct Answer: B
Rationale: The correct answer is B because folic acid plays a crucial role in reducing the risk of neural tube defects in the fetus during early pregnancy. Folic acid is essential for proper development of the neural tube, which forms the baby's brain and spinal cord. This is why it is particularly important during preconception care and in the early stages of pregnancy.
Choice A is incorrect because folic acid is not specifically for preventing iron deficiency anemia in pregnancy. Choice C is incorrect as folic acid is important throughout pregnancy, not just in the first trimester. Choice D is incorrect because folic acid does not directly enhance the absorption of calcium and vitamin D.

At her first prenatal visit, a woman relates that her maternal aunt has cystic fibrosis (CF), an autosomal recessive illness. Which of the following comments is appropriate for the nurse to make at this time?
- A. We can check to see whether or not you are a carrier for cystic fibrosis.
- B. It is unnecessary for you to worry since your aunt is not a direct relation.
- C. You should have an amniocentesis to see whether or not your child has the disease.
- D. Please ask your mother whether she has ever had any symptoms of cystic fibrosis.
Correct Answer: A
Rationale: Carrier testing can determine if the woman carries the CF gene.
During a preconception consultation, a patient asks about factors affecting egg quality. What should the nurse explain?
- A. Age is the primary factor influencing egg quality.
- B. Diet has no impact on egg quality.
- C. Hormonal treatments guarantee improvement in egg quality.
- D. Exercise is the only way to enhance egg quality.
Correct Answer: A
Rationale: The correct answer is A: Age is the primary factor influencing egg quality. As a tutor, I will explain this by stating that the quality of a woman's eggs declines with age due to factors like genetic abnormalities and decreased mitochondrial function. This decline can affect fertility and increase the risk of chromosomal abnormalities in offspring.
For the incorrect choices:
B: Diet can impact egg quality by providing essential nutrients, so this choice is incorrect.
C: Hormonal treatments may help with fertility but do not guarantee improvement in egg quality, making this choice incorrect.
D: Exercise can contribute to overall health but is not the only way to enhance egg quality, making this choice incorrect.
In summary, age is a crucial factor affecting egg quality, while diet, hormonal treatments, and exercise play roles but are not primary influencers.
During preconception counseling, the nurse discusses the impact of advanced maternal age. What should the nurse emphasize?
- A. Advanced maternal age has no impact on pregnancy outcomes.
- B. Fertility declines with age, increasing the risk of complications.
- C. Only the father's age affects pregnancy success.
- D. Advanced maternal age reduces the need for prenatal care.
Correct Answer: B
Rationale: The correct answer is B because fertility declines with age, leading to increased risk of complications such as chromosomal abnormalities and miscarriages. This is important to emphasize during preconception counseling. Choice A is incorrect as advanced maternal age does impact pregnancy outcomes. Choice C is incorrect because both maternal and paternal age can affect pregnancy success. Choice D is incorrect as advanced maternal age actually increases the need for additional prenatal care due to higher risk factors.
A nurse is discussing male infertility with a client. Which of the following is a common cause of reduced male fertility?
- A. High testosterone levels
- B. Frequent use of lubricants during intercourse
- C. Smoking and alcohol consumption
- D. Daily exercise routines
Correct Answer: C
Rationale: The correct answer is C: Smoking and alcohol consumption. Smoking and alcohol can negatively impact male fertility by affecting sperm quality and quantity. Smoking can lead to DNA damage in sperm, while alcohol can disrupt hormone levels. High testosterone levels (A) actually do not commonly cause reduced fertility. Frequent use of lubricants (B) may hinder sperm movement, but it's not a common cause. Daily exercise (D) can improve overall health and fertility.
What is the primary purpose of performing a semen analysis during infertility testing?
- A. To determine the presence of infections.
- B. To evaluate sperm count, motility, and morphology.
- C. To check for hormonal imbalances.
- D. To test for genetic abnormalities in sperm.
Correct Answer: B
Rationale: The primary purpose of performing a semen analysis during infertility testing is to evaluate sperm count, motility, and morphology. This is crucial in assessing male fertility potential. Sperm count indicates the quantity of sperm, motility refers to their ability to move effectively, and morphology assesses the shape and structure of sperm. These factors directly impact the likelihood of successful fertilization. Checking for infections (choice A) is important but not the primary purpose. Hormonal imbalances (choice C) are typically evaluated through blood tests, not semen analysis. Testing for genetic abnormalities in sperm (choice D) is a separate test and not the primary focus of a semen analysis.
