A couple has been counseled for genetic anomalies. They ask you, 'What is karyotyping?' Which description is most accurate?

Correct Answer: C

Rationale: Karyotyping provides genetic information such as gender and chromosomal structure. The lecithin/sphingomyelin (L/S) ratio, not karyotyping, reveals lung maturity. Although karyotyping can detect genetic anomalies, the range of normal is nondescriptive, and not all such anomalies display obvious physical deformities. The term 'deformities' is a nondescriptive word, and physical anomalies may be present that are not detected by genetic studies (e.g., cardiac malformations).

Correct Answer: D

Rationale: In this scenario, option D, "Tell the client her questions are irrelevant," is the inappropriate action for the nurse to perform before beginning the health history interview. This response is incorrect because it undermines the client's concerns and disregards the importance of active listening and building a therapeutic relationship. Option A is correct as it demonstrates the nurse's willingness to listen to the client's concerns and shows empathy. Option B is appropriate as it sets a positive tone for the interaction, promoting trust and openness. Option C is also a crucial step as it helps create a conducive environment for the client to share information comfortably. In the context of maternal newborn nursing, establishing a trusting relationship with the client is essential for providing effective care. By showing respect, empathy, and active listening skills, the nurse can gather important information, address any concerns, and provide appropriate support during the maternal newborn healthcare journey. It is crucial for nurses to approach each interaction with sensitivity and professionalism to promote positive health outcomes for both the mother and newborn.

Correct Answer: A

Rationale: The correct answer is A) Climacteric. Ovarian function and hormone production decline during the climacteric phase, which is part of the menopausal transition in women. This phase marks the gradual decrease in ovarian function leading to the cessation of menstruation and reproductive ability. Option B) Menarche refers to the first menstrual period in girls, signifying the onset of puberty and reproductive capability. It is the beginning of the menstrual cycle, not a phase of decline in ovarian function. Option C) Menopause is the permanent cessation of menstruation, marking the end of the reproductive years. While ovarian function declines during menopause, the specific transitional phase characterized by this decline is the climacteric, not menopause itself. Option D) Puberty is the stage of development when adolescents reach sexual maturity and become capable of reproduction. It is characterized by the onset of secondary sexual characteristics and the maturation of the reproductive system, not the decline in ovarian function. Understanding the phases of ovarian function and hormone production in women is crucial for maternal newborn nurses as it impacts fertility, menopausal symptoms, and overall reproductive health of women. Recognizing the climacteric phase as the period of declining ovarian function can help nurses provide appropriate care and support to women experiencing menopausal transitions.

Correct Answer: B

Rationale: The correct answer is B) Bony pelvis. During pregnancy, the bony pelvis plays a crucial role in providing protection to the pelvic structures and accommodating the growing fetus. The bony pelvis is made up of the hip bones, sacrum, and coccyx, forming a sturdy and protective basin that houses the developing baby. Its shape and size are essential for ensuring a safe passage for the fetus during childbirth. Option A) Perineum is incorrect because while it is an important area anatomically related to childbirth, it does not provide the same level of structural support and protection as the bony pelvis. Option C) Vaginal vestibule is incorrect as it refers to the entrance of the vagina and does not have a direct role in protecting the pelvic structures during pregnancy. Option D) Fourchette is incorrect as it is a specific anatomical term referring to the posterior aspect of the vulva and is not directly involved in protecting the pelvic structures or accommodating the fetus. Understanding the role of the bony pelvis in pregnancy is crucial for maternal newborn nurses as it impacts their ability to assess and provide care to pregnant women. Knowledge of pelvic anatomy and its functions is essential for understanding the mechanics of childbirth and potential complications that may arise during labor and delivery.

Correct Answer: B

Rationale: The correct answer is B) Women, ages 21 to 34 years, have the highest rates of specific alcohol-related problems. This information is crucial for nurses working in maternal newborn nursing as it highlights a specific demographic group that is at higher risk for alcohol-related issues during pregnancy. Understanding this data allows nurses to tailor their assessments, interventions, and education to better support this group of women in making healthier choices during pregnancy. Option A is incorrect because cigarette smoking has significant adverse effects on maternity-related health, including increased risks of preterm birth, low birth weight, and complications during pregnancy. Nurses need to be well-informed about the dangers of smoking during pregnancy to provide effective counseling and support to pregnant women who smoke. Option C is incorrect because while excessive caffeine intake from coffee can have negative effects during pregnancy, such as increased risk of miscarriage and low birth weight, it is not directly linked to birth defects. Nurses should educate pregnant women on safe levels of caffeine consumption rather than attributing birth defects solely to coffee consumption. Option D is incorrect as prescription psychotherapeutic drugs can indeed affect the fetus. Nurses need to be knowledgeable about the potential risks and benefits of medications prescribed to pregnant women, as some psychotherapeutic drugs may pose risks to fetal development and require careful monitoring and management during pregnancy. In maternal newborn nursing, having a comprehensive understanding of substance abuse and its impact on pregnancy outcomes is essential for providing safe and effective care to both the mother and the newborn. Nurses play a critical role in educating, supporting, and advocating for pregnant women to promote healthy lifestyle choices and positive birth outcomes.
