Human Growth and Development Final Exam
1. Taking tests and answering questionnaires are examples of __________.
- A. research designs
- B. theories
- C. hypotheses
- D. research methods
Correct answer: D
Rationale: Taking tests and answering questionnaires are examples of research methods. Research methods refer to the specific approaches used in conducting research, such as collecting data, analyzing information, and drawing conclusions. In this case, tests and questionnaires are tools used to gather information and data for research purposes, making them examples of research methods. Choices A, B, and C are incorrect because research designs refer to the overall structure and plan of a study, theories are explanations developed through research and observation, and hypotheses are specific predictions or statements that can be tested through research.
2. Jalynn is in the last half of the first month of her pregnancy. Which of the following is developing the fastest?
- A. circulatory system
- B. endocrine system
- C. nervous system
- D. skin
Correct answer: C
Rationale: During the last half of the first month of pregnancy, the nervous system develops the fastest among the options provided. This rapid development of the nervous system is crucial for the overall growth and functioning of the fetus. The nervous system includes the brain and spinal cord, which are essential for various bodily functions and will continue to develop throughout the pregnancy. The circulatory system, although important, does not develop at the fastest rate during this stage. The endocrine system and skin also play significant roles in the development of the fetus but are not the systems that develop the fastest in the last half of the first month of pregnancy.
3. 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.
4. The most rapid prenatal changes take place in the period of the __________.
- A. zygote
- B. blastocyst
- C. embryo
- D. fetus
Correct answer: C
Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.
5. Certified nurse-midwives __________.
- A. cannot legally deliver babies at home in most states
- B. have degrees in nursing and additional training in childbirth management
- C. can perform cesarean deliveries and administer medication to control pain
- D. are not medical professionals, but are trained in labor and delivery support Answer: B Page Ref: 96 Skill Level: Understand with each. Topic: Approaches to Childbirth Difficulty Level: Moderate
Correct answer: B
Rationale: Certified nurse-midwives have degrees in nursing and additional training in childbirth management. They are qualified to provide prenatal care, support during labor and delivery, as well as postpartum care. They are licensed medical professionals who can assist with normal childbirth, but they do not perform surgical procedures like cesarean deliveries. They also focus on providing holistic and personalized care to women throughout the childbirth process.
