1. 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.

2. Which statement about the Nurse-Family Partnership is true?

• A. It is an international program to reduce the risk of teratogens.
• B. One of its goals is to promote competent early caregiving.
• C. It is a series of childbirth classes offered at many U.S. hospitals.
• D. It provides family planning and genetic counseling to couples.

Correct answer: B

Rationale: The statement that is true about the Nurse-Family Partnership is that one of its goals is to promote competent early caregiving. The program provides support and guidance to first-time mothers to help them develop their caregiving skills and promote healthy child development. Choice A is incorrect because the program focuses on promoting healthy child development and supporting mothers, not specifically reducing the risk of teratogens. Choice C is incorrect because the Nurse-Family Partnership is not a series of childbirth classes but a program that involves home visits and support. Choice D is incorrect because the program's main focus is on supporting mothers in caregiving and child development, not primarily on family planning and genetic counseling.

3. Which of the following best describes a sequential design?

• A. Does not address diversity in developmental outcomes.
• B. Permits researchers to check if cohort effects are operating.
• C. Is less efficient than a longitudinal design.
• D. Makes cross-sectional, but not longitudinal, comparisons.

Correct answer: B

Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.

4. Which statement provides an example of an age-graded influence?

• A. Paul learned to play the violin at a young age.
• B. Jack enjoys hiking in the mountains.
• C. Sarah prefers reading mystery novels.
• D. Alex excels in mathematics.

Correct answer: A

Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.

5. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.

• A. cross-sectional
• B. experimental
• C. longitudinal
• D. correlational

Correct answer: C

Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.
