1. The effects of stress on the developing organism can be greatly reduced if the expectant mother __________.

• A. has access to social support during stressful periods
• B. takes a low dose of anti-anxiety medication
• C. takes a folic acid supplement early in pregnancy
• D. is placed on bed rest during the last trimester

Correct answer: A

Rationale: Having access to social support during stressful periods can greatly reduce the effects of stress on the developing organism. Social support can provide emotional comfort, practical assistance, and a sense of belonging, which can help the expectant mother cope with stress more effectively. This support system can also help mitigate the negative impact of stress on the developing baby during pregnancy. Choices B, C, and D are incorrect because while folic acid is important for prenatal health, it does not directly address the effects of stress. Taking anti-anxiety medication should be done under medical supervision and as a last resort due to potential risks to the developing baby. Bed rest during the last trimester is not a solution to reduce the effects of stress and may not address the underlying causes of stress.

2. 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.

3. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.

• A. lower birth weight and higher risk of premature birth
• B. suppressed development of the immune system
• C. serious damage to the central nervous system
• D. improved fetal cardiovascular functioning

Correct answer: D

Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.

4. G. Stanley Hall and his student, Arnold Gesell, __________.

• A. discovered that prenatal growth is strikingly similar in many species
• B. launched the normative approach
• C. constructed the first standardized intelligence test
• D. were the forefathers of psychoanalytic theory

Correct answer: B

Rationale: G. Stanley Hall and his student, Arnold Gesell, launched the normative approach. This approach involves studying large numbers of people of different ages and examining the age-related averages of behaviors to establish norms or typical development patterns. These scholars focused on the systematic observation of how and when certain behaviors appear in children. Choices A, C, and D are incorrect because they do not accurately reflect the contributions of G. Stanley Hall and Arnold Gesell in the field of developmental psychology.

5. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.

• A. long-lived predatory fish; mercury
• B. freshwater fish; lead
• C. long-lived predatory fish; polychlorinated biphenyls
• D. freshwater fish; radiation

Correct answer: A

Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.
