A nurse is assessing the knowledge of new parents of a child born with Klinefelter syndrome. Which statement accurately describes this genetic disorder?

Correct Answer: A

Rationale: Klinefelter syndrome, also known as trisomy XXY, is a sex chromosomal deviation that is expressed in males. Turner syndrome (monosomy X) is displayed in females. Most males with Klinefelter syndrome are tall, may be infertile, and are slow to learn; however, those who have mosaic Klinefelter syndrome may be fertile as adults.

Correct Answer: B

Rationale: This mother will likely experience a disruption in the family process related to the birth of a baby with an inherited disorder. Therefore, the probable nursing diagnosis for this family is 'Interrupted family processes.' Women commonly experience 'body image disturbances in the postpartum period'; however, this nursing diagnosis is unrelated to giving birth to a child with Down syndrome. The mother will likely have a mix of emotions that may include anxiety, guilt, and denial, but this nursing diagnosis is not the most essential for this family. 'Risk for injury' is not an applicable nursing diagnosis.

Correct Answer: B

Rationale: Aneuploidy is an abnormality of number that is also the leading genetic cause of mental retardation. Chromosomal abnormalities occur in fewer than 1% of newborns. Down syndrome is the most common form of a trisomal abnormality, an abnormality of chromosome number (47 chromosomes). Unbalanced translocation is an abnormality of chromosomal structure that often has serious clinical effects.

Correct Answer: B

Rationale: The correct answer is B) Myotonia and vasocongestion. In the context of the physiologic process of sexual response, myotonia refers to muscle tension or contractions, while vasocongestion refers to the engorgement of blood vessels in the genital area. These two processes are key components of the sexual response cycle as described by Masters and Johnson. Option A) Coitus, masturbation, and fantasy, is incorrect because it does not specifically describe the physiological processes involved in the sexual response. Option C) Erection and orgasm, is incorrect as it only highlights two stages of the sexual response cycle and does not encompass the full physiological response. Option D) Excitement, plateau, and orgasm, is incorrect as it describes the phases of sexual response according to Masters and Johnson, but does not directly address the physiological processes of myotonia and vasocongestion. Understanding the physiological aspects of the sexual response is crucial in the field of maternal newborn nursing. By comprehending these processes, healthcare providers can better assist and educate individuals on sexual health, reproductive physiology, and prenatal care. This knowledge is essential for promoting healthy pregnancies, addressing sexual concerns, and providing comprehensive care to expectant mothers and newborns.

Correct Answer: C

Rationale: Rationale: The guiding principle of preconception care, as indicated by option C, is to encourage healthy lifestyles for families desiring pregnancy. This option is correct because preconception care focuses on optimizing a woman's health before becoming pregnant to improve outcomes for both the mother and the baby. By promoting healthy behaviors such as maintaining a balanced diet, engaging in regular exercise, avoiding harmful substances, and managing chronic conditions, preconception care aims to enhance fertility, reduce the risk of birth defects and pregnancy complications, and promote overall well-being. Option A is incorrect because preconception care is not solely about preventing pregnancy complications but rather about proactively promoting health before conception occurs. Option B is also incorrect as the goal of preconception care is not to identify who should not become pregnant but rather to support all women in optimizing their health for potential pregnancy. Option D is incorrect because preconception care encompasses more than just informing women about prenatal care; it involves comprehensive health promotion strategies before conception. In an educational context, understanding the guiding principle of preconception care is crucial for nurses and healthcare providers working in maternal newborn health. By recognizing the importance of promoting healthy lifestyles before pregnancy, healthcare professionals can empower women to take control of their health, increase their chances of a healthy pregnancy, and contribute to positive maternal and neonatal outcomes. Teaching this principle to students and practitioners helps them provide holistic and proactive care to women during their reproductive years.
