Fetal Development NCLEX Questions Questions
Question 1 of 5
Where should a pregnant person at 34 weeks with preeclampsia deliver?
Correct Answer: B
Rationale: In the context of pharmacology and fetal development, the correct answer is B) Level II hospital for a pregnant person at 34 weeks with preeclampsia. Preeclampsia is a serious condition characterized by high blood pressure and organ damage that can be life-threatening to both the pregnant person and the fetus. A Level II hospital is equipped to handle high-risk pregnancies and provide the necessary monitoring and interventions to manage complications like preeclampsia. Choosing option A) Level I hospital may not provide the specialized care and resources needed for a high-risk pregnancy like preeclampsia at 34 weeks. Option C) home delivery is not appropriate for a pregnant person with preeclampsia due to the risk of serious complications that may require immediate medical attention. Option D) in-hospital birthing center may not have the level of medical expertise and resources available at a Level II hospital to manage preeclampsia effectively. Educationally, understanding the appropriate level of care for specific pregnancy complications like preeclampsia is crucial for healthcare providers to ensure the safety and well-being of both the pregnant person and the fetus. It highlights the importance of proper assessment, monitoring, and management of high-risk pregnancies to optimize outcomes for mother and baby.
Question 2 of 5
Expectant parents of twins tell the nurse they are having fraternal twins and are asking the nurse what that means. Which reply of the nurse is correct?
Correct Answer: D
Rationale: Rationale: The correct response is D) Your twins will be as alike as any two siblings. Explanation: Fraternal twins, also known as dizygotic twins, result from the fertilization of two separate eggs by two different sperm. As a result, they share about 50% of their genetic material, just like any two siblings born at different times. This means that fraternal twins can be of the same or different genders, and they do not have identical genetic makeup. Why other options are incorrect: A) Your twins will both be boys: This is incorrect as the gender of fraternal twins can be the same or different. B) Your twins are called monozygotic: This is incorrect as monozygotic twins are identical twins, not fraternal twins. C) You have one placenta and one of each of the fetal membranes called the chorion and amnion: This describes a different type of twins, known as monochorionic diamniotic twins, not fraternal twins. Educational context: Understanding the types of twins is essential in pharmacology, as genetic factors can influence drug responses. Knowing the genetic relationship between twins helps healthcare professionals provide personalized care and medication management, considering potential genetic variations. It is crucial for nursing students to grasp these concepts to deliver optimal care to patients, including expectant parents of twins.
Question 3 of 5
An expectant mother asks the nurse when her baby’s heart will begin to beat. The nurse explains that this will occur at which time?
Correct Answer: B
Rationale: In fetal development, the correct answer is option B) The 4th gestational week. This is when the baby's heart begins to beat. At this early stage, the baby's heart is already formed and starts beating as blood begins to circulate. It is a crucial milestone in the development of the fetus as it marks the beginning of the circulatory system functioning. Option A) The 8th gestational week is incorrect because by this time, the baby's heart has been beating for approximately a month already. Option C) The 12th gestational week is also incorrect as the baby's heart has been beating for around 8 weeks by this time. Option D) The 16th gestational week is too late for the onset of the baby's heartbeat, as it would have been established by the 4th week. Understanding the timeline of fetal development is essential for healthcare professionals, especially in pharmacology, as many medications can impact the developing fetus differently depending on the stage of pregnancy. This knowledge helps in providing safe and effective care to pregnant women and their unborn babies.
Question 4 of 5
During pregnancy, which structure secretes hormones until the placenta takes over?
Correct Answer: C
Rationale: In the context of pharmacology and fetal development, understanding the role of structures in hormone secretion during pregnancy is crucial. In this question, the correct answer is C) Corpus luteum. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, to support the early stages of pregnancy until the placenta is fully developed and can take over hormone production. Decidua basalis (A) is the part of the endometrium that lies under the implanted embryo and eventually becomes part of the placenta. It does not secrete hormones independently but contributes to the formation of the placenta. Chorionic villi (B) are finger-like projections that help in the exchange of nutrients and waste between the mother and fetus but do not secrete hormones. Syncytiotrophoblast (D) is a crucial component of the developing placenta and plays a role in hormone production once the placenta is fully functional. However, it is not the structure that secretes hormones until the placenta takes over; that role belongs to the corpus luteum. Understanding the sequential changes in hormone production during pregnancy is essential for healthcare providers, especially when considering pharmacological interventions that may impact hormone levels and fetal development. This knowledge helps in ensuring the safety and well-being of both the pregnant individual and the developing fetus.
Question 5 of 5
During formation of the germ layer in the embryo, which layer gives rise to the nervous system?
Correct Answer: A
Rationale: Understanding the formation of the germ layers during embryonic development is crucial in pharmacology, especially when considering drug effects on fetal development. In this context, the correct answer is A) Ectoderm, as it gives rise to the nervous system. The ectoderm is the outermost layer of the germ layers and is responsible for forming structures such as the skin, hair, nails, and the entire nervous system, including the brain and spinal cord. The incorrect options are B) Mesoderm, C) Endoderm, and D) Entoderm. Mesoderm gives rise to structures like muscles, bones, and the circulatory system. Endoderm forms internal organs such as the gastrointestinal tract and lungs. Entoderm is not a valid term in embryonic development. Educationally, understanding the origin of different tissues and organs from specific germ layers is fundamental for pharmacology students. Knowing which layer gives rise to the nervous system, in this case, can help anticipate how certain drugs may affect neurodevelopment if exposed during pregnancy. This knowledge is essential for making informed decisions regarding drug safety during pregnancy and for understanding the potential risks associated with medication use in pregnant women.
