1. During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.
- A. premature labor
- B. limb deformities
- C. respiratory distress at birth
- D. low birth weight Answer: D Page Ref: 83 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Difficult
Correct answer: D
Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.
2. When __________, newborn Takeo's toes should fan out and curl as his foot twists in.
- A. a bright light shines in his eyes
- B. his bare foot touches a flat surface
- C. his cheek is stroked near the corner of his mouth
- D. the sole of his foot is stroked from toe to heel
Correct answer: D
Rationale: The correct answer is D because the description of the twisting and fanning out of newborn Takeo's toes suggests the Babinski reflex, which is typically elicited by stroking the sole of the foot from toe to heel. The Babinski reflex is a normal response in newborns and indicates proper neurological development. Choices A, B, and C are incorrect as they do not elicit the specific response described in the question.
3. Among all Western nations, which country has the highest percentage of extremely poor children?
- A. the United States
- B. Canada
- C. Germany
- D. France
Correct answer: A
Rationale: The correct answer is 'the United States.' According to the information provided, the United States has the highest percentage of extremely poor children among Western nations. This is supported by the extract, which states that the United States leads in this aspect. Choices B, C, and D are incorrect as the question specifically asks for the country with the highest percentage of extremely poor children among Western nations, which is the United States.
4. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.
- A. mesoderm; neuron tract
- B. neural tube
- C. endoderm; neural tube
- D. neuron tract
Correct answer: B
Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.
5. What is one strength of the cross-sectional design?
- A. It provides evidence about individual trends.
- B. It cannot be threatened by cohort effects.
- C. It is not plagued with dropout or practice effects.
- D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate
Correct answer: C
Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.
