Fetal Development Questions Questions
Question 1 of 5
Which statement best describes the changes that occur during the fetal period of development?
Correct Answer: A
Rationale: The correct answer is A because during the fetal period, organ systems continue to mature and develop to become fully functional. This includes refining the structures and functions of organs that have already been formed during the embryonic period. Option B is incorrect because basic organ systems are already formed during the embryonic period. Option C is incorrect as organs are still susceptible to damage during the fetal period. Option D is incorrect because the development of placental oxygen–carbon dioxide exchange primarily occurs during the early stages of pregnancy, not specifically during the fetal period.
Question 2 of 5
The nurse is explaining fetal circulation to a group of nursing students. Which information should be included in the teaching session? (Select all that apply.)
Correct Answer: C
Rationale: The correct answer is C: The ductus venosus shunts blood from the liver to the inferior vena cava. During fetal circulation, the ductus venosus allows oxygenated blood from the placenta to bypass the liver and flow directly into the inferior vena cava. This is important for fetal circulation as the liver is not fully functional in the fetus. After birth, the ductus venosus closes as the liver becomes fully operational. Rationale for incorrect choices: A: After birth, the ductus venosus closes, not remains open. B: The foramen ovale shunts blood from the right atrium to the left atrium, not related to the ductus venosus. D: This choice is a repetition of the correct information but incorrectly states the destination of the shunted blood.
Question 3 of 5
The nurse is counseling a couple who just learned their 16-week fetus tested positive for a serious genetic disorder. Which action by the nurse is inappropriate upon learning that the couple plan to continue the pregnancy?
Correct Answer: A
Rationale: The correct answer is A because it respects the couple's decision-making autonomy. The nurse should support their choice to continue the pregnancy without suggesting termination. Providing information, emotional support, and connecting them with a support group are appropriate actions. It is crucial to respect the couple's decision and provide compassionate care regardless of their choice. The other choices are incorrect because they may undermine the couple's autonomy and may not be aligned with their wishes.
Question 4 of 5
A patient at 13 weeks gestation asks the nurse how her baby is nourished during pregnancy. Which information does the nurse use to explain the process to the mother?
Correct Answer: D
Rationale: Step-by-step rationale for choice D being correct: 1. Glucose, amino acids, and oxygen are essential nutrients for fetal growth. 2. These nutrients pass through the placenta from the mother's blood to the baby's blood. 3. This exchange occurs via diffusion and active transport processes. 4. The placenta acts as a barrier, filtering out harmful substances like waste products and CO2. 5. This process ensures the baby receives necessary nutrients for development. Summary of why other choices are incorrect: A: Fetal waste products and CO2 pass from the baby to the mother, not the other way around. B: The placenta facilitates nutrient and oxygen exchange but does not create them. C: The mother's and baby's blood do not mix; exchange of nutrients occurs through the placental barrier.
Question 5 of 5
A female patient is concerned about an inability to become pregnant after trying for 1 year. Which information collected during a health history causes the nurse the greatest amount of concern about possible infertility?
Correct Answer: C
Rationale: The correct answer is C because hot flashes and mood swings can indicate hormonal imbalances, which are common causes of infertility. This symptom suggests potential issues with ovulation or other reproductive system functions. Choice A is irrelevant to infertility. Choice B, age alone does not indicate infertility. Choice D, a history of pelvic inflammatory disease can cause infertility, but symptoms indicating current hormonal imbalances are of more immediate concern.
