What guidance should the nurse provide to a man who smokes two packs a day and is concerned about infertility?

Correct Answer: D

Rationale: The correct answer is D) Smoking can reduce the quality of your sperm. This guidance is crucial because smoking has been linked to decreased sperm quality, which can lead to infertility issues. Smoking can damage the DNA in sperm, decrease sperm motility, and affect overall sperm health, making conception more difficult. By providing this information, the nurse helps the man understand the direct impact of his smoking habit on his fertility. Option A is incorrect because even if the sperm count is initially normal, smoking can still impact the quality of sperm, which is essential for successful conception. Option B is incorrect as it falsely states that only marijuana affects sperm count, neglecting the well-documented negative effects of tobacco smoking. Option C is misleading as it downplays the impact of smoking on fertility by focusing solely on lung cancer, ignoring the broader health implications for reproductive health. In an educational context, it is important for nurses to provide evidence-based information to individuals seeking guidance on lifestyle factors that can influence their reproductive health. By addressing the specific concerns of the individual and highlighting the effects of smoking on sperm quality, nurses can empower patients to make informed decisions to improve their chances of conception.

Correct Answer: D

Rationale: In maternal newborn nursing, understanding the impact of advanced paternal age on offspring health is crucial. The correct answer is D) Down syndrome. Advanced paternal age, typically considered over 40 years, is a well-established risk factor for Down syndrome due to the increased likelihood of errors in sperm cell division leading to an extra copy of chromosome 21 in the offspring. Option A) Autosomal dominant disorder is incorrect because advanced paternal age specifically relates to chromosomal abnormalities, not autosomal dominant inheritance patterns. Schizophrenia (Option B) and Autism spectrum disorder (Option C) have been associated with advanced paternal age in some studies, but the most widely recognized and direct association is with Down syndrome. Educationally, this question highlights the importance of considering both maternal and paternal factors in assessing genetic risks in newborns. It reinforces the need for healthcare providers to educate individuals on the impact of advanced paternal age on pregnancy outcomes and the increased risk of chromosomal abnormalities like Down syndrome. By understanding these associations, nurses can provide comprehensive care and support to families facing such genetic challenges.

Correct Answer: D

Rationale: The correct answer is D) Ova and sperm are transferred to one tube. In GIFT, both the egg and sperm are collected and transferred directly into the fallopian tube, allowing fertilization to occur inside the woman's body. This method differs from in vitro fertilization (IVF) where fertilization occurs outside the body in a laboratory setting. Option A is incorrect because semen is not collected after laparoscopy in GIFT; instead, both egg and sperm are collected prior to the procedure. Option B is incorrect as GIFT can be performed even if a woman has one fallopian tube as long as it is healthy. Option C is incorrect because ovulation is induced and monitored in GIFT, it is not spontaneous. Educationally, understanding the specifics of assisted reproductive technologies like GIFT is crucial for nurses working in maternal newborn health. This knowledge allows nurses to provide accurate information and support to patients undergoing fertility treatments. Understanding the differences between GIFT and other fertility treatments is essential for providing comprehensive care to patients.

Correct Answer: C

Rationale: The correct answer is option C: Healthy women with fibrocystic breast disease find lumpiness with pain and tenderness in varying degrees in the breast tissue during menstrual cycles. This is the correct choice because fibrocystic changes in the breast are common, benign changes that many women experience. These changes are influenced by hormonal fluctuations during the menstrual cycle, leading to cyclic breast pain and lumpiness. Option A is incorrect because fibrocystic changes are not a disease but rather a benign condition. Option B is incorrect as fibrocystic changes are not considered a premalignant disorder; they do not increase the risk of breast cancer. Option D is also incorrect because the tenderness and lumpiness associated with fibrocystic changes typically improve after menstruation, not worsen. In an educational context, it is crucial for nurses to provide accurate information about fibrocystic changes in the breast to alleviate anxiety and misconceptions among clients. Understanding these normal variations can empower women to practice breast self-awareness and differentiate between benign changes and concerning abnormalities, promoting early detection and breast health awareness.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) S-phase index. The S-phase index is a measure of the percentage of cells actively synthesizing DNA at a given time. In the context of cancer, a low S-phase index indicates that fewer cells are actively dividing, suggesting a slower-growing cancer. Option A) Tumor ploidy refers to the DNA content in tumor cells and does not specifically provide information about the rate of cell division. Option C) Nuclear grade is a measure of the appearance of the cell nucleus and is used to assess the aggressiveness of cancer cells, but it does not directly indicate the rate of cell division. Option D) Estrogen-receptor assay is a test used to determine if a cancer is sensitive to hormonal therapies and does not provide information about the rate of cell division. Understanding the S-phase index is crucial in oncology as it helps healthcare providers determine the growth rate of the cancer cells, which influences treatment decisions. Educating nurses on these concepts enables them to better support patients by explaining complex medical information and assisting in shared decision-making processes regarding treatment options.
