Human Growth and Development Exam 1
1. Which statement about the human immunodeficiency virus (HIV) is true?
- A. About 30 percent of all new HIV infections affect women.
- B. In South Africa, 30 percent of all pregnant women are HIV-positive.
- C. About 30 percent of new HIV infections occur in developing countries.
- D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.
Correct answer: B
Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.
2. A major limitation of systematic observation is that it __________.
- A. provides little information on how participants actually behave
- B. tells investigators little about the reasoning behind responses and behaviors
- C. underestimates the capacities of individuals who have difficulty putting their thoughts into words
- D. ignores participants with poor memories, who may have trouble recalling exactly what happened
Correct answer: B
Rationale: A major limitation of systematic observation is that it tells investigators little about the reasoning behind responses and behaviors. Systematic observation focuses more on recording observable behaviors rather than delving into the underlying reasons or thought processes driving those behaviors. Choices A, C, and D are incorrect because systematic observation can indeed provide detailed information on how participants actually behave, it doesn't necessarily underestimate the capacities of individuals who struggle with verbal expression, and it doesn't solely ignore participants with poor memories as it can capture behavior in real-time regardless of memory recall.
3. How can families prevent escalating demands that lead to chaos?
- A. Parental multitasking
- B. Eating separate meals
- C. Compression of family routines
- D. High-quality child care that is affordable and reliable
Correct answer: D
Rationale: High-quality child care that is affordable and reliable can help prevent escalating demands on families that lead to chaos. This is achieved by providing a stable and supportive environment for children, enabling parents to balance work and family responsibilities effectively. Access to reliable child care reduces stress and helps in preventing chaos within the family, ultimately leading to improved well-being for both parents and children. Choices A, B, and C are incorrect as they do not directly address the need for external support to manage family demands and prevent chaos. Parental multitasking, eating separate meals, and compressing family routines may not provide the necessary stability and support required to prevent escalating demands on families.
4. Which individual is most likely to experience the greatest percentage of REM sleep?
- A. Sammy, a preschool child
- B. Jake, a full-term newborn
- C. Sarah, a teenager
- D. Cheryl, a preterm newborn Answer: D Page Ref: 104 Copyright © 2018 Laura E. Berk. All Rights Reserved. 32 Test Bank for Berk, Development Through the Lifespan, 7e Skill Level: Apply Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: D
Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.
5. Which of the following is the best available predictor of infant survival and healthy development?
- A. Birth length
- B. Combined Apgar score
- C. Delivery date
- D. Birth weight
Correct answer: D
Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.
