1. Which statement about a blastocyst is true?

• A. It consists of a single cell.
• B. It is a structure that feeds the developing organism.
• C. Between the seventh and ninth days, it burrows deep into the uterine lining.
• D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

2. Kathryn would like to give birth in a medical facility that permits maternal control over labor and delivery, including choice of delivery positions, and allows the presence of family members and friends. Kathryn should consider giving birth at a __________.

• A. private home
• B. local hospital
• C. doula center
• D. freestanding birth center

Correct answer: D

Rationale: Kathryn should consider giving birth at a freestanding birth center. Freestanding birth centers provide a setting where women can have more control over their labor and delivery experience, including the choice of delivery positions, the presence of family members and friends, and involvement in decision-making throughout the process. These centers offer a more home-like environment compared to hospitals while still providing access to medical support if needed. Choices A (private home) and B (local hospital) do not necessarily guarantee the level of control and facilities Kathryn seeks. While a doula center (Choice C) can provide additional support during labor, it may not offer the same level of medical facilities and control over the birthing process as a freestanding birth center.

3. 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.

4. Which statement about prenatal rubella is true?

• A. The greatest damage occurs when rubella strikes during the fetal period.
• B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems. Copyright © 2018 Laura E. Berk. All Rights Reserved. 15 Test Bank for Berk, Development Through the Lifespan, 7e
• C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
• D. Infection during the embryonic period is less harmful than during other prenatal periods. Answer: B Page Ref: 86‒87 Skill Level: Understand known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.

5. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.

• A. sensorimotor reflex
• B. circular reaction
• C. mental representation
• D. goal-directed behavior

Correct answer: B

Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.
