Human Growth and Development Exam Questions
1. 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.
2. Ethnographic research is directed toward understanding a culture through __________ observation.
- A. naturalistic
- B. participant
- C. systematic
- D. structured
Correct answer: B
Rationale: Ethnographic research is directed toward understanding a culture through participant observation. This type of observation involves the researcher immersing themselves in the culture being studied, actively participating in the daily activities and interactions of the group being studied. Through participant observation, researchers can gain a deep and nuanced understanding of the culture from the inside. Choice A, naturalistic observation, typically refers to observing subjects in their natural environment without interference, but it does not involve actively participating in the culture. Choice C, systematic observation, focuses on carefully planned and structured data collection methods but may not involve direct participation. Choice D, structured observation, implies a predefined set of guidelines for observation but lacks the immersive aspect of participant observation.
3. What reflex protects an infant from strong stimulation?
- A. Moro
- B. eye-blink
- C. sucking
- D. palmar grasp
Correct answer: B
Rationale: The correct answer is B: eye-blink. The eye-blink reflex is the one that protects an infant from strong stimulation by causing them to quickly shut their eyes in response to sudden bright light or a loud noise. This reflex helps to safeguard the infant's sensitive eyes from potential harm. The Moro reflex (choice A) is the startle reflex, the sucking reflex (choice C) helps with feeding, and the palmar grasp reflex (choice D) is when the infant's fingers close around an object placed in their hand; none of these reflexes specifically protect the infant from strong stimulation.
4. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.
- A. Vitamin A
- B. Folic acid
- C. Vitamin D
- D. Vitamin C
Correct answer: B
Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.
5. It is difficult to isolate the precise damage caused by illegal drugs during pregnancy because __________.
- A. most drug-using mothers refuse to participate in teratology research
- B. the majority of babies born to drug-using mothers do not survive for more than a few days
- C. most drug-using mothers quit using illegal drugs during the first trimester of pregnancy
- D. drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses
Correct answer: D
Rationale: The difficulty in isolating the precise damage caused by illegal drugs during pregnancy is due to the fact that drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses. This makes it challenging to identify the specific impact of each individual factor on prenatal development. Choices A, B, and C are incorrect because they do not address the complexity of the situation involving drug users during pregnancy. Most drug-using mothers refusing to participate in teratology research, the majority of babies not surviving, or drug-using mothers quitting during the first trimester do not directly explain the difficulty in isolating the precise damage caused by illegal drugs during pregnancy.
