Human Growth and Development Final Exam Answers
1. Chinara is Rh-negative and Savon, her first child, is Rh-positive. Chinara's doctor will probably __________.
- A. give Savon a vaccine to prevent heart damage and intellectual disabilities
- B. advise Chinara not to have another child due to Rh incompatibility
- C. give Chinara a vaccine to prevent the buildup of antibodies to the foreign Rh protein
- D. do nothing because firstborn children are not affected by Rh incompatibility
Correct answer: C
Rationale: Chinara is Rh-negative and Savon, her first child, is Rh-positive. This presents a risk of Rh incompatibility in future pregnancies. To prevent the buildup of antibodies to the foreign Rh protein and protect future pregnancies, Chinara's doctor will likely give her a vaccine known as RhoGAM to prevent her immune system from reacting to Rh-positive blood cells. This vaccine helps to minimize the risks of complications in subsequent pregnancies. Choice A is incorrect because the vaccine is given to the mother, not the child. Choice B is incorrect as advising against having more children is not a typical response when preventive measures are available. Choice D is incorrect because all subsequent pregnancies are at risk of Rh incompatibility, not just the firstborn child.
2. Who is generally regarded as the founder of the child study movement?
- A. Charles Darwin
- B. G. Stanley Hall
- C. Alfred Binet
- D. Sigmund Freud
Correct answer: B
Rationale: G. Stanley Hall is generally regarded as the founder of the child study movement. He established the first American research laboratory dedicated to child psychology and education, helping to pioneer the scientific study of child development. Choices A, C, and D are incorrect as they were not primarily associated with founding the child study movement. Charles Darwin is known for his contributions to the theory of evolution, Alfred Binet is famous for developing the first intelligence test, and Sigmund Freud is renowned for his work in psychoanalysis.
3. The term teratogen refers to __________.
- A. any environmental agent that causes damage during the prenatal period
- B. a limited time span during which a part of the body is biologically prepared to develop rapidly
- C. a rapid period of prenatal neurological development
- D. a synthetic hormone used to prevent miscarriage
Correct answer: A
Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.
4. When children are research participants, __________.
- A. Investigators need to seek the opinion of others if in doubt about the harmful effects of research.
- B. They have the right to concealment of their identity on information collected in the course of research.
- C. There is a need to inform them or their parents of the results of the research.
- D. Informed consent of their parents as well as others who act on their behalf should be obtained.
Correct answer: D
Rationale: When children are research participants, it is essential to obtain informed consent from their parents or others who act on their behalf. This is to ensure that the child's rights and well-being are protected during the research process. Informed consent is a fundamental ethical principle in research involving children, as they may not have the capacity to fully understand the implications of their participation. Choice A is incorrect because seeking the opinion of others when in doubt about harmful effects is not a substitute for informed consent. Choice B is incorrect because children do not have an absolute right to conceal their identity in research, especially when it comes to ensuring their safety and well-being. Choice C is incorrect as it is important to inform children or their parents about the results of the research to maintain transparency and respect for their participation.
5. During pregnancy, the placenta __________.
- A. forms in the second trimester of pregnancy
- B. encloses the developing organism in amniotic fluid
- C. contains one large vein that delivers nutrients to the embryo
- D. delivers food and oxygen to the developing organism
Correct answer: D
Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.
