Human Growth and Development Exam Questions
1. During the second trimester, a white, cheeselike substance called __________ emerges on the skin.
- A. lanugo
- B. corpus luteum
- C. vernix
- D. chorion
Correct answer: C
Rationale: During the second trimester of pregnancy, a white, cheeselike substance called vernix emerges on the skin of the developing fetus. Vernix is a protective layer that helps prevent the skin from becoming waterlogged during the time in the amniotic fluid. Choice A, lanugo, is incorrect as lanugo refers to the fine, soft hair that covers the body of a fetus. Choice B, corpus luteum, is incorrect as it is a temporary endocrine structure involved in the menstrual cycle. Choice D, chorion, is incorrect as it is one of the membranes that surround the embryo and later the fetus.
2. What is the most common approach to controlling pain during labor?
- A. an anesthetic
- B. a spinal block
- C. fetal monitoring
- D. epidural analgesia
Correct answer: D
Rationale: Epidural analgesia is the most common approach to controlling pain during labor. It involves the administration of pain medication through a catheter placed in the epidural space of the spine, providing pain relief while allowing the mother to remain alert and participate in the birthing process. It is preferred by many women due to its effectiveness in reducing labor pain. Choices A, B, and C are incorrect as they do not directly address pain management during labor. While an anesthetic and a spinal block are forms of pain relief, epidural analgesia is specifically the most common method used for pain control during labor.
3. Many theorists believe that behaviorism and social learning theory ________.
- A. overemphasize the plasticity of cognitive development
- B. overestimate people's contributions to their own development
- C. offer too narrow a view of important environmental influences
- D. overemphasize each individual's unique life history
Correct answer: C
Rationale: Many theorists believe that behaviorism and social learning theory offer too narrow a view of important environmental influences. This is because they focus mainly on observable behaviors and external factors, neglecting the role of internal cognitive processes and individual differences in shaping development. Choices A, B, and D are incorrect because behaviorism and social learning theory do not specifically emphasize the plasticity of cognitive development, overestimate people's contributions to their own development, or overemphasize each individual's unique life history. Instead, they are criticized for providing a limited perspective by focusing predominantly on external stimuli and behaviors.
4. What is a characteristic of structured interviews?
- A. Do not yield the same depth of information as a clinical interview
- B. Are flexible because questions are phrased differently for each participant
- C. Bring together a wide range of information on one person
- D. Tell researchers little about the reasoning behind participants' responses
Correct answer: A
Rationale: The correct answer is A. Structured interviews do not yield the same depth of information as a clinical interview because they involve a set of standardized questions that are asked in the same way to all participants. This lack of flexibility may limit the depth and richness of the responses obtained compared to a more open-ended clinical interview. Choices B, C, and D are incorrect because structured interviews are not flexible in question phrasing, do not necessarily bring together a wide range of information on one person, and can provide insights into participants' reasoning behind responses depending on the design of the structured questions.
5. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.
- A. long-lived predatory fish; mercury
- B. freshwater fish; lead
- C. long-lived predatory fish; polychlorinated biphenyls
- D. freshwater fish; radiation
Correct answer: A
Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.
