Human Growth and Development Exam Questions
1. Dr. McBride wants to know if the teacher's use of encouragement in the classroom affects the children's self-esteem. To assign children to treatment conditions, Dr. McBride should __________.
- A. carefully distribute the children according to their test scores
- B. divide the children so each group has an equal number of boys and girls
- C. draw the children's names out of a hat
- D. assign the quieter children to the same treatment condition
Correct answer: C
Rationale: Drawing the children's names out of a hat is a way to randomly assign them to treatment conditions. Random assignment helps to ensure that any differences in self-esteem that may be observed in the study are not due to pre-existing characteristics of the children. This method helps to establish a cause-and-effect relationship between the teacher's use of encouragement and the children's self-esteem. Choice A is incorrect because assigning children based on test scores may introduce bias into the study. Choice B is incorrect as balancing gender is not relevant to the research question. Choice D is incorrect as it introduces a bias by selecting a specific group of children based on a characteristic unrelated to the study objective.
2. Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________.
- A. fetal alcohol syndrome
- B. partial fetal alcohol syndrome
- C. alcohol-related neurodevelopmental disorder
- D. cytomegalovirus
Correct answer: A
Rationale: Terrance exhibits a combination of physical abnormalities like a thin upper lip, short eyelid openings, a small head, and a smooth philtrum, along with developmental delays and cognitive impairments. These characteristics are indicative of fetal alcohol syndrome (FAS), which is caused by maternal alcohol consumption during pregnancy. FAS is a severe condition resulting from prenatal alcohol exposure and is characterized by a range of physical, cognitive, and behavioral issues. Choice A, fetal alcohol syndrome, is the correct answer as it aligns with Terrance's symptoms and the effects of maternal alcohol consumption during pregnancy. Choices B, C, and D are incorrect because they do not encompass the full spectrum of symptoms and impairments presented by Terrance, which are specific to fetal alcohol syndrome.
3. Swaddling newborns __________.
- A. increases crying
- B. hinders early motor development
- C. promotes an insecure attachment relationship
- D. restricts movement and increases warmth
Correct answer: D
Rationale: Swaddling newborns restricts their movement by wrapping them snugly in a blanket, which helps to mimic the feeling of security they had in the womb. It also helps to maintain their warmth and can promote better sleep patterns. Choices A, B, and C are incorrect because swaddling does not increase crying, hinder early motor development, or promote an insecure attachment relationship. Instead, it provides comfort, warmth, and a sense of security for newborns.
4. Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership __________ than comparison-group agemates.
- A. scored lower in impulsivity and overactivity
- B. had lower academic achievement scores
- C. showed more aggressive behavior
- D. reported less alcohol and drug use
Correct answer: D
Rationale: Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership reported less alcohol and drug use compared to their comparison-group agemates. This indicates that the program may have a positive impact in reducing risky behaviors among adolescents whose mothers received home visits. Choices A, B, and C are incorrect because the extract specifically mentions that the children reported less alcohol and drug use, and there is no mention of impulsivity, overactivity, academic achievement scores, or aggressive behavior in this context.
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.
