Fetal Development NCLEX Questions Questions
Question 1 of 5
What are probable signs of pregnancy? Select all that apply.
Correct Answer: B
Rationale: In the context of fetal development, probable signs of pregnancy refer to those signs that strongly suggest the presence of a developing fetus. Among the options provided, only fetal movement (Option B) is a probable sign of pregnancy. This is because fetal movement, also known as quickening, is a definitive sign of pregnancy and indicates the presence of a living fetus in the uterus. A) Amenorrhea, the absence of menstruation, is a presumptive sign of pregnancy and not a probable sign. It can be caused by factors other than pregnancy. C) Goodell sign, which refers to softening of the cervix, is a probable sign of pregnancy but is not among the options provided as correct. D) A positive pregnancy test is a presumptive sign of pregnancy as it can be influenced by other factors such as medications or certain medical conditions. Educationally, understanding the difference between probable, presumptive, and positive signs of pregnancy is crucial for healthcare providers, especially in pharmacology. This knowledge helps in accurate diagnosis and appropriate management of pregnant patients. Recognizing fetal movement as a probable sign can aid in providing appropriate prenatal care and support to pregnant individuals.
Question 2 of 5
The nurse is providing education about the newborn to a pregnant person and the soon-to-be grandparents. What information is the most important for the nurse to discuss to assist the extended family in adapting to their new role?
Correct Answer: B
Rationale: In the context of pharmacology and fetal development, understanding the importance of extended family role expectations is crucial for the nurse to discuss with the pregnant person and soon-to-be grandparents. The correct answer, option B, is the most important because it addresses the broader family dynamics and support system that will influence the newborn's well-being. By discussing extended family role expectations, the nurse can help facilitate a smooth transition into the new role for the grandparents and ensure that they provide the necessary support for the newborn's health and development. Option A, how to bathe the newborn, while important, is a more practical skill that can be learned through demonstration and practice. Option C, childbirth preparation, is essential but focuses more on the immediate needs of the pregnant person rather than the extended family's role. Option D, breast-feeding, is crucial for the newborn's nutrition but may not directly impact the extended family's adaptation to their new role. By emphasizing the significance of extended family role expectations, the nurse can promote a supportive environment for the newborn's overall well-being and development, which is essential in pharmacology and fetal development education.
Question 3 of 5
The nurse explains to the patient at 28 weeks’ gestation not to lie flat on their back during the remainder of the pregnancy. What does this precaution prevent?
Correct Answer: D
Rationale: In pregnancy, lying flat on the back can compress the inferior vena cava, reducing blood return to the heart and leading to a decrease in maternal cardiac output and blood pressure. This can result in vena cava syndrome, causing dizziness, lightheadedness, and a drop in blood pressure. By advising the patient not to lie flat on their back, the nurse is helping to prevent this condition and maintain adequate blood flow to the fetus. Option A, acid reflux, is not related to the position of lying flat on the back. Acid reflux is more commonly associated with the relaxation of the lower esophageal sphincter during pregnancy due to hormonal changes. Option B, headaches, are not directly linked to lying flat on the back. Headaches during pregnancy can be due to various factors such as hormonal changes, dehydration, stress, or sinus congestion. Option C, pregnancy-induced hypertension (preeclampsia), is a serious condition characterized by high blood pressure and often accompanied by proteinuria. Avoiding lying flat on the back does not directly prevent preeclampsia, although it may help with blood flow regulation. Educationally, understanding the physiological changes in pregnancy is crucial for nurses to provide appropriate care and education to pregnant individuals. Teaching about positional precautions helps to promote maternal and fetal well-being by preventing potential complications like vena cava syndrome. It also emphasizes the importance of patient education and self-care during pregnancy to optimize outcomes.
Question 4 of 5
The prenatal nurse is discussing fetal circulation with a student nurse. What statement by the student indicates to the prenatal nurse the student understands the information?
Correct Answer: D
Rationale: In understanding fetal circulation, it is crucial to grasp the unique structures and pathways involved in the developing fetus. Option D, "There are two arteries and one vein in the umbilical cord," is the correct answer. This statement reflects an understanding of the composition of the umbilical cord, which consists of two umbilical arteries that carry deoxygenated blood from the fetus to the placenta and one umbilical vein that returns oxygenated blood from the placenta to the fetus. Regarding the incorrect options: A) The ductus arteriosus does not attach the umbilical artery to the hepatic artery. The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, allowing blood to bypass the lungs. B) The ductus venosus does not attach the pulmonary artery to the aorta. It is a shunt that connects the umbilical vein to the inferior vena cava, bypassing the liver. C) The foramen ovale is not located in the ventricular septum. It is an opening between the atria of the heart, allowing blood to bypass the fetal lungs. In an educational context, understanding fetal circulation is vital for healthcare professionals working with pregnant women and newborns. Knowledge of how oxygenated and deoxygenated blood flow in the fetus helps in detecting and managing congenital heart defects and other conditions that may impact fetal well-being. By grasping the specifics of fetal circulation, nurses and other healthcare providers can better care for both the mother and the developing fetus.
Question 5 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.
