1. During the second month of pregnancy, __________.

• A. the umbilical cord first appears as a primitive body stalk
• B. touch sensitivity extends to most of the body
• C. the heart develops separate chambers
• D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.

2. Fetal monitoring is __________.

• A. rarely used in U.S. hospitals
• B. linked with low birth weight
• C. linked with a decreased rate of cesarean deliveries
• D. required in most U.S. hospitals

Correct answer: D

Rationale: Fetal monitoring is required in most U.S. hospitals during labor and delivery to track the baby's heart rate and the mother's contractions. This helps healthcare providers to assess the well-being of the fetus and make timely decisions regarding the need for interventions if any complications arise. Choices A, B, and C are incorrect because fetal monitoring is a standard procedure in most hospitals to ensure the safety and health of both the mother and the baby during labor.

3. Which factor disrupts the brain's regulation of hunger and metabolism?

• A. Self-regulation
• B. Frequent eating out
• C. Reduced sleep
• D. Using screen media

Correct answer: C

Rationale: Reduced sleep is the correct answer as it affects hormones that regulate hunger and metabolism, leading to increased appetite and weight gain. Self-regulation is not directly related to the brain's regulation of hunger and metabolism. Frequent eating out may impact food choices and portion sizes but is not specifically linked to disrupting the brain's regulation. Using screen media can affect sleep patterns but is not as directly related to the brain's regulation of hunger and metabolism as reduced sleep.

4. Around __________, Baby Alanna should begin to prefer a salty taste to plain water.

• A. 2 weeks
• B. 6 weeks
• C. 2 months
• D. 4 months

Correct answer: D

Rationale: At around 4 months of age, babies begin to develop a preference for salty taste over plain water. This preference is part of their sensory development and exploration of tastes. Introducing a variety of flavors, including salty tastes, at this stage helps broaden the baby's palate and acceptance of different foods later on. Choices A, B, and C are incorrect as babies typically do not develop a preference for salty tastes over plain water at 2 weeks, 6 weeks, or 2 months of age. These earlier stages are more focused on milk feeding and the introduction of solid foods usually begins around 4-6 months of age.

5. Dr. Redmund characterizes his view of development as a bioecological model. His perspective is aligned with that of which theorist?

• A. Jean Piaget
• B. Urie Bronfenbrenner
• C. Lev Vygotsky
• D. Niko Tinbergen

Correct answer: B

Rationale: Dr. Redmund's view of development aligns with the bioecological model, which is associated with Urie Bronfenbrenner. This model emphasizes the interaction between an individual's biological characteristics and environmental influences in development. Jean Piaget's theory focuses on cognitive development, Lev Vygotsky's theory emphasizes social interactions, and Niko Tinbergen is known for his work in animal behavior and instinct, not human development. Therefore, the correct answer is Urie Bronfenbrenner (Choice B).
