Human Growth and Development Final Exam
1. Lanugo ________.
- A. permits food and oxygen to reach the organism
- B. provides the fetus a cushion against jolts caused by the mother's movements
- C. helps regulate the fetus's body temperature
- D. helps the vernix stick to the skin
Correct answer: D
Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
2. At Kohlberg's Stage __________, individuals can imagine alternatives to their own social order, and they emphasize fair procedures for interpreting and changing the law.
- A. 3, the 'good boy/good girl' orientation
- B. 4, the social-order-maintaining orientation
- C. 5, the social contract orientation
- D. 6, the universal ethical principle orientation
Correct answer: C
Rationale: The correct answer is C: '5, the social contract orientation.' At Kohlberg's Stage 5, individuals begin to question their own social order and focus on principles of justice and fairness. This stage emphasizes the importance of social contracts and agreements based on mutual benefit. Choice A is incorrect as the 'good boy/good girl' orientation is characteristic of Stage 3. Choice B, the social-order-maintaining orientation, does not align with the description provided in the question. Choice D, the universal ethical principle orientation, is associated with Stage 6, where individuals act based on self-chosen ethical principles.
3. Which Apgar criterion can be more difficult to apply to newborns of all races?
- A. pink color
- B. reflex irritability
- C. limp muscle tone
- D. strong breathing
Correct answer: D
Rationale: Among the Apgar criteria, the pink color (choice A), reflex irritability (choice B), and limp muscle tone (choice C) are relatively easy to assess in newborns of all races. However, the criterion that can be more difficult to apply to newborns of all races is strong breathing (choice D). This is because evaluating the strength of a newborn's breathing can be more subjective and require careful observation. Unlike the other criteria that have more visible and objective indicators, assessing the strength of breathing might vary based on the observer's interpretation, making it more challenging to apply universally.
4. __________ increases tenfold from the twentieth week until birth.
- A. Amniotic fluid
- B. Brain weight
- C. Fetal length
- D. Neuron production
Correct answer: B
Rationale: Brain weight increases tenfold from the twentieth week until birth. This rapid growth and development of the brain during the prenatal period is crucial for setting the foundation for future cognitive and neurological functions. Choices A, C, and D are incorrect because although they also undergo changes during prenatal development, none of them increase tenfold from the twentieth week until birth, unlike brain weight.
5. According to Piaget, in which stage of cognitive development is four-year-old R’Monte who engages in make-believe play by stirring beads in a bowl and saying, “Soup is ready!�
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. sociocultural
Correct answer: B
Rationale: According to Piaget's theory of cognitive development, four-year-old R’Monte's engagement in make-believe play, such as pretending to stir beads in a bowl and creating imaginary soup, indicates that he is in the preoperational stage of cognitive development. This stage is characterized by symbolic thinking, pretend play, language development, and egocentrism. Choice A, sensorimotor, is incorrect as this stage occurs in infancy and focuses on sensory experiences and object permanence. Choice C, concrete operational, is incorrect as this stage occurs around ages 7-11 and involves logical reasoning about concrete events. Choice D, sociocultural, is incorrect as it does not correspond to Piaget's stages of cognitive development.
