Human Growth and Development Exam Questions
1. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.
- A. a burst of motor activity
- B. a period of sleep
- C. a rise in Liz's heart rate
- D. a drop in Liz's body temperature
Correct answer: A
Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.
2. 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.
3. Chinara is Rh-negative and Savon, her first child, is Rh-positive. Chinara's doctor will probably __________.
- A. give Savon a vaccine to prevent heart damage and intellectual disabilities
- B. advise Chinara not to have another child due to Rh incompatibility
- C. give Chinara a vaccine to prevent the buildup of antibodies to the foreign Rh protein
- D. do nothing because firstborn children are not affected by Rh incompatibility
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.
4. In an experimental study examining whether children who are read to more often score higher on vocabulary tests in first grade, the independent variable would be the __________.
- A. frequency of read-alouds
- B. type of books parents read
- C. child’s vocabulary score Copyright © 2018 Laura E. Berk. All Rights Reserved. 31 Test Bank for Berk, Development Through the Lifespan, 7e
- D. difficulty of vocabulary words Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Difficult
Correct answer: A
Rationale: In an experimental study, the independent variable is the factor being manipulated or controlled by the researcher. In this case, the frequency of read-alouds is the variable that researchers would intentionally change or vary to see its effect on the dependent variable, which is the children's vocabulary scores. The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.
5. What are the most obvious organized patterns of behavior in a newborn baby?
- A. Reflexes
- B. States of arousal
- C. Shrill cries
- D. Sleep patterns
Correct answer: A
Rationale: The correct answer is A: Reflexes. Reflexes are automatic, involuntary responses to specific stimuli and are the most obvious organized patterns of behavior in a newborn baby. Examples of newborn reflexes include sucking, rooting, grasping, and the Moro reflex. These reflexes are crucial for the newborn's survival and overall development. Choice B, states of arousal, refers to different levels of consciousness and responsiveness, not organized behavior patterns. Choice C, shrill cries, is a form of communication and not an organized behavior pattern. Choice D, sleep patterns, while important for newborns, are not the most obvious organized behavior patterns.
