1. A combined Apgar score of __________ indicates that the infant is in good physical condition.

• A. less than 3
• B. 3 or 4
• C. 5 or 6
• D. 7 or better

Correct answer: D

Rationale: A combined Apgar score of 7 or better indicates that the infant is in good physical condition. The Apgar score is a quick assessment of a newborn's overall health shortly after birth. It evaluates the baby's heart rate, respiratory effort, muscle tone, reflexes, and color. A score of 7 or higher indicates that the baby is adjusting well to life outside the womb. Choices A, B, and C are incorrect as they represent scores that indicate the infant may need medical attention or assistance as they are below the threshold of 7 which signifies good physical condition.

2. Development is best understood as __________.

• A. genetically determined
• B. environmentally influenced
• C. an unsolvable puzzle
• D. a series of complex exchanges between nature and nurture

Correct answer: D

Rationale: The correct answer is D. Development is best understood as a series of complex exchanges between nature (genetic factors) and nurture (environmental influences). This perspective emphasizes the interaction and interplay between genetic predispositions and environmental experiences in shaping an individual's development. Choices A and B are too extreme as they suggest that development is solely determined by genetics or solely influenced by the environment, which is not the case. Choice C is incorrect as development is not viewed as an unsolvable puzzle but rather as a dynamic process influenced by multiple factors.

3. __________ may heighten the effects of a high-fat diet.

• A. Sex hormones
• B. Over-the-counter medications
• C. Free radicals
• D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

4. Like longitudinal research, cross-sectional studies can be threatened by __________.

• A. practice effects
• B. participant dropout
• C. sequential timing
• D. cohort effects

Correct answer: D

Rationale: Cross-sectional studies can be threatened by cohort effects because different age groups may have experienced different historical or social contexts, influencing the results. This disparity can lead to invalid comparisons between age groups, confounding the study's findings. Option A, practice effects, refer to changes in participants' behavior due to repeated testing, not a specific threat to cross-sectional studies. Participant dropout (Option B) is a threat related to attrition in longitudinal studies, not cross-sectional studies. Sequential timing (Option C) does not pose a threat to cross-sectional studies; instead, it refers to the order of tasks in a study design.

5. 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.
