Human Growth and Development Final Exam Answers Questions
Question 1 of 9
Currently, the most widely used potent teratogen is __________.
Correct Answer: D
Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.
Question 2 of 9
Three-month-old Jefferson will probably listen longer to __________ than to __________.
Correct Answer: C
Rationale: Three-month-old Jefferson will likely listen longer to human speech compared to nonspeech sounds because infants have a natural preference for speech sounds. This preference is believed to be attributed to their biological readiness to learn language and communicate with others. Choice A is incorrect because voices are a form of human speech, which is preferred over pure tones. Choice B is incorrect as noises do not necessarily engage infants' attention as effectively as human speech. Choice D is incorrect because Jefferson is more likely to listen longer to his native language rather than a foreign language at this early age.
Question 3 of 9
The third stage of labor lasts about __________.
Correct Answer: A
Rationale: The correct answer is A: 5 to 10 minutes. The third stage of labor typically lasts about 5 to 10 minutes. This stage begins after the baby is born and ends when the placenta is delivered. It is the shortest stage of labor compared to the first and second stages. Choice B, 20 to 50 minutes, is incorrect as it is too long for the duration of the third stage. Choice C, 4 to 6 hours, and Choice D, 12 to 14 hours, are also incorrect as they are significantly longer than the actual duration of the third stage of labor.
Question 4 of 9
Dr. Rizvi studies the relationship between changes in the brain and the developing person's cognitive processing and behavior patterns. She is part of a group of researchers from the fields of psychology, biology, neuroscience, and medicine. This approach to development is known as __________.
Correct Answer: D
Rationale: Dr. Rizvi's approach to development, involving studying the relationship between changes in the brain and cognitive processing and behavior patterns, aligns with developmental cognitive neuroscience. This field combines research from various disciplines to understand how brain development influences cognitive processes and behaviors. Choice A, behaviorism, focuses on observable behaviors influenced by external stimuli. Choice B, cognitive-development theory, emphasizes cognitive growth stages. Choice C, the information-processing approach, centers on how individuals perceive, store, and retrieve information.
Question 5 of 9
What is the function of the amniotic fluid?
Correct Answer: B
Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.
Question 6 of 9
Dr. Bigelow is interested in studying musical prodigies. Which method is best suited for this type of research?
Correct Answer: C
Rationale: A case study would be the best method for Dr. Bigelow to study musical prodigies. In a case study, the researcher can closely examine and analyze the unique characteristics, abilities, and behaviors of individual subjects. This method allows for in-depth exploration of a specific phenomenon, making it ideal for investigating exceptional cases such as musical prodigies. Naturalistic observation involves observing subjects in their natural environment without interference, which may not provide the detailed insights needed for studying musical prodigies. Clinical interviews focus on gathering information through structured questioning, not ideal for studying unique talents. Structured interviews involve asking a set of predetermined questions, which may not allow for the depth of exploration required for studying musical prodigies.
Question 7 of 9
Chinara is Rh-negative and Savon, her first child, is Rh-positive. Chinara's doctor will probably __________.
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.
Question 8 of 9
Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?
Correct Answer: B
Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.
Question 9 of 9
The information-processing approach views the human mind as a __________.
Correct Answer: D
Rationale: The information-processing approach views the human mind as a symbol-manipulating system through which information flows. This perspective emphasizes how information is received, processed, stored, and retrieved in the mind, similar to how a computer processes data through symbols and operations. Choices A, B, and C are incorrect because they do not align with the fundamental principles of the information-processing approach, which focuses on the mind's symbolic manipulation of information rather than being a socially mediated process, a collection of stimuli and responses, or a system of genetically programmed behaviors.
