Human Growth and Development Final Exam Answers
1. Men with even tiny amounts of dioxin in their bloodstream father __________.
- A. nearly twice as many girls as boys
- B. nearly three times as many boys as girls
- C. more twins and triplets than unaffected men
- D. fewer children than unaffected men
Correct answer: A
Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.
2. 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.
3. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.
- A. malnutrition
- B. physical abnormality
- C. low birth weight
- D. sudden infant death syndrome
Correct answer: C
Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.
4. By age 2, children __________.
- A. take turns in face-to-face interaction
- B. can infer a speaker's indirectly expressed intention
- C. adjust their speech to fit the age of their listeners
- D. adjust their speech to fit the social status of their listeners
Correct answer: C
Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.
5. Newborns of smoking mothers __________.
- A. are more attentive to sounds
- B. display more muscle tension
- C. less often have colic
- D. are less excitable when visually stimulated Answer: B Page Ref: 84 Skill Level: Understand known or suspected teratogens. Copyright © 2018 Laura E. Berk. All Rights Reserved. 12 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Environmental Influences Difficulty Level: Moderate
Correct answer: B
Rationale: Newborns of smoking mothers display more muscle tension. This is because nicotine in cigarettes can lead to increased muscle tension in babies, which can affect their physical development and potentially lead to future health issues. This is one of the negative effects of smoking during pregnancy on the developing fetus.
