The nurse is discussing genetically linked diseases with a couple planning a pregnancy. The female states, 'I am concerned because there is a history of sickle-cell disease in my family.' Which information from the nurse is correct?

Correct Answer: C

Rationale: Rationale: The correct answer is C) The male partner needs genetic testing. Explanation: Sickle-cell disease is an autosomal recessive genetic disorder, meaning both parents must carry the gene for their child to inherit the disease. In this scenario, if the female carries the sickle-cell gene, the male partner's genetic status is crucial. By undergoing genetic testing, the male partner can determine if he also carries the gene. If he does not, the risk of passing on sickle-cell disease to their offspring decreases significantly. Why the other options are incorrect: A) Any offspring will have the disease: This is incorrect as both parents must be carriers for the offspring to inherit sickle-cell disease. B) Only male children will have the disease: Sickle-cell disease is not sex-linked; both males and females can inherit it. D) The couple should not become pregnant: This is an extreme and unnecessary recommendation. With proper genetic counseling and testing, the couple can make informed decisions about their pregnancy options. Educational context: Understanding the inheritance patterns of genetic diseases like sickle-cell disease is crucial for healthcare professionals providing counseling to individuals or couples planning a pregnancy. Genetic testing and counseling can help assess the risk of passing on genetic disorders and guide decision-making regarding family planning.

Correct Answer: B

Rationale: In this scenario, option B, "The patient had a vasectomy reversed," is the most concerning finding obtained during the health history. This is because a vasectomy reversal does not always guarantee the restoration of fertility, and there may be complications or issues that arise post-reversal that could impact the patient's ability to conceive. From an educational standpoint, it is crucial to understand the implications of surgical interventions like vasectomy reversal and the potential impact on fertility. Option A, "The patient is a passionate gardener," is not as concerning because gardening, in itself, does not typically impact male fertility. Option C, "The patient rides a bicycle daily to work," may have some impact on fertility due to potential pressure on the genital area, but it is not as concerning as a vasectomy reversal. Option D, "The patient is concerned about infertility," is not the most concerning finding as it is expected for a patient seeking help at an infertility clinic to be concerned about infertility. It is essential for nurses to be able to differentiate between normal concerns and potential risk factors during health assessments in fertility clinics.

Correct Answer: A

Rationale: In the process of oogenesis, which is the formation of female gametes (eggs), a single cycle typically results in the production of one mature ovum (egg cell). This is because during oogenesis, a diploid primary oocyte undergoes meiosis to produce a haploid secondary oocyte and a polar body. The secondary oocyte then completes meiosis II to yield a mature ovum and another polar body. However, it is important to note that only one mature ovum is produced as the final product of oogenesis. Option A (1) is the correct answer because, as explained, only one mature ovum is generated from a single cycle of oogenesis. Options B, C, and D are incorrect because they suggest the production of more than one mature ovum, which does not align with the biological process of oogenesis. Educationally, understanding the process of oogenesis and the formation of female gametes is crucial in the fields of reproductive biology and pharmacology. This knowledge is fundamental for healthcare professionals, especially when discussing topics related to fertility, reproductive health, and the effects of medications on the female reproductive system.

Correct Answer: D

Rationale: The correct answer is D) “The sample can be obtained using a transcervical approach.” This statement indicates a need for further education because amniocentesis is actually performed by inserting a needle through the abdomen into the amniotic sac, not through the cervix. This demonstrates a misunderstanding of the procedure itself. Option A is incorrect as it correctly states that amniocentesis can be used to test for neural tube defects, which is a valid indication for the procedure. Option B is also incorrect as the timing mentioned (between 15 and 20 weeks' gestation) is accurate for when amniocentesis is typically performed. Option C is incorrect as it accurately describes the process of amniocentesis, showing an understanding of how the procedure is conducted. Educationally, understanding the correct technique for performing amniocentesis is crucial to ensure the safety and accuracy of the procedure. Misinformation about the procedure could lead to unnecessary anxiety or confusion for the patient. It is important for healthcare providers to provide accurate information to patients to ensure they are well-informed and prepared for any diagnostic procedures they may undergo during pregnancy.

Correct Answer: C

Rationale: The correct answer is C) “You are at the very beginning of your cycle and will be getting your period very soon.” This statement is correct because low estradiol and progesterone levels indicate the beginning of the menstrual cycle, suggesting the patient has not ovulated yet. This educational context is crucial for the patient to understand their fertility window and timing for conception. Option A is incorrect as low hormone levels do not indicate ovulation has already occurred. Option B is incorrect as the timing for intercourse should align with ovulation, which has not yet happened based on the hormone levels. Option D is incorrect because repeating the blood work next week may not provide the patient with the necessary information about their current cycle phase. Understanding hormonal changes is vital for successful conception and fertility tracking.
