Match each term with its description. Embryoblast

Correct Answer: C

Rationale: In this question, the correct answer is C) The fertilized egg as it separates into 2 parts, the embryoblast and trophoblast. This is because the embryoblast refers to the inner cell mass of the blastocyst, which will develop into the embryo. Option A, B, and D are marked as "None" because they do not accurately describe the embryoblast. Selecting any of these options would not provide the correct match with the term. Educationally, understanding the process of embryonic development is crucial in the field of healthcare, especially for nurses preparing for the NCLEX exam. Knowing the terminology and stages of fetal development can help nurses provide better care for pregnant women and their unborn babies. It also ensures a strong foundation in reproductive health and prenatal care, which are essential aspects of nursing practice.

Correct Answer: A

Rationale: The correct answer is A) Connects the pulmonary artery and the aorta, bypassing the lungs. The ductus arteriosus is a fetal circulatory shunt that allows blood to bypass the non-functioning fetal lungs by connecting the pulmonary artery to the aorta. This shunt is essential for fetal circulation to ensure oxygenated blood from the placenta bypasses the lungs and reaches the systemic circulation. Option B) Connects the right and left atria is incorrect because the structure that connects the right and left atria in fetal circulation is the foramen ovale, not the ductus arteriosus. Option C) Connects the right and left ventricles is incorrect because there is no shunt that directly connects the right and left ventricles in fetal circulation. Option D) Allows the umbilical vein to bypass the liver to flow into the inferior vena cava is incorrect because this action is associated with the ductus venosus, not the ductus arteriosus. Understanding fetal circulation and the function of each shunt is crucial in the context of neonatal nursing and pediatric care. Knowledge of these structures helps healthcare professionals assess and manage congenital heart defects and other cardiac conditions in neonates. It is important for NCLEX test-takers to have a solid understanding of fetal circulation to provide safe and effective care to pediatric patients.

Correct Answer: B

Rationale: In the scenario of conception occurring, the correct answer is B) Human chorionic gonadotropin maintains the corpus luteum, keeping estrogen and progesterone levels high. This is crucial for the preservation of the endometrium, preventing its shedding. The incorrect options can be explained as follows: A) The anterior pituitary temporarily stopping LH and FSH production would not maintain the endometrium as these hormones are essential for the menstrual cycle, not for supporting a pregnancy. C) and D) These options are marked as "None," which is incorrect as the correct answer is B. Educational context: Understanding the role of hormones in pregnancy is vital for healthcare professionals, especially those specializing in maternal-fetal care. Human chorionic gonadotropin plays a significant role in supporting early pregnancy by preserving the corpus luteum, which in turn maintains the necessary hormonal environment to support the developing fetus. This knowledge is essential for providing optimal care to pregnant individuals and ensuring successful outcomes in prenatal care.

Correct Answer: C

Rationale: The correct answer is C) Report persistent contractions, vaginal bleeding, fluid leaking, or fever. Rationale: After an amniocentesis, it is crucial for the client to be aware of potential complications that may arise. Reporting persistent contractions, vaginal bleeding, fluid leaking, or fever is essential as these symptoms could indicate infection, preterm labor, or other serious issues that require immediate medical attention. Timely reporting and intervention can help prevent adverse outcomes for both the mother and the fetus. Option A) Drink 1 to 2 quarts of clear fluid to replace fluid taken in the procedure is incorrect because while hydration is important, it is not the most critical aspect of post-amniocentesis care. Option B) Resume all normal activities when desired is incorrect as the client should be advised to avoid strenuous activities and rest to reduce the risk of complications. Option D) Eat a diet with increased iron for the 2 days after amniocentesis is incorrect because while iron is important in pregnancy, there is no specific need for increased iron intake immediately after amniocentesis. In an educational context, understanding the importance of monitoring for and reporting potential complications post-amniocentesis is crucial for providing safe and effective care to pregnant clients undergoing this procedure. Nurses and healthcare providers play a key role in educating clients about signs and symptoms to watch for and when to seek medical help to ensure optimal outcomes for both the mother and the baby.

Correct Answer: C

Rationale: The correct answer is C) Discuss options with the couple, including amniocentesis to determine whether the fetus is affected. This is the most appropriate action for the nurse to take in this situation. By discussing options, including amniocentesis, the nurse is providing the couple with the necessary information to make informed decisions about their pregnancy. Option A is incorrect because it is not the nurse's role to recommend or pressure the couple to have an abortion. This goes against the principle of patient autonomy and informed decision-making. Option B is incorrect because stating a 50% chance without further testing or counseling can be misleading and potentially cause unnecessary anxiety for the couple. It is important to provide accurate information and offer appropriate testing to determine the fetus's status. Option D is incorrect because while emotional support is important in this situation, the primary focus should be on providing the couple with information and options regarding the genetic condition. Referring them to a psychologist should be done in conjunction with providing genetic counseling and support. In an educational context, this question highlights the importance of genetic counseling in cases of known genetic conditions in families. It emphasizes the nurse's role in providing accurate information, supporting decision-making, and offering appropriate testing options to help the couple navigate the complexities of their situation.
