1. The concept of ________ means that because of their genetic makeup, individuals differ in their responsiveness to qualities of the environment.

• A. gene-environment interaction
• B. niche-picking
• C. passive correlation
• D. evocative correlation

Correct answer: A

Rationale: The correct answer is A, gene-environment interaction. This concept highlights that genetic factors play a role in how individuals react to environmental factors. Niche-picking (choice B) refers to the tendency of individuals to select environments that complement their genetic predispositions, not the inherent genetic differences in responsiveness. Passive correlation (choice C) involves the association between the genetic makeup of parents and the environment they provide for their children, not individual differences in responsiveness. Evocative correlation (choice D) relates to the idea that an individual's genetic traits can elicit certain responses from others in the environment, rather than individual differences in responsiveness.

2. Anoxia during labor and delivery can cause __________.

• A. spina bifida
• B. anencephaly
• C. cerebral palsy
• D. muscular dystrophy

Correct answer: C

Rationale: Anoxia during labor and delivery can cause cerebral palsy. Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. It is caused by damage to the developing brain, often due to a lack of oxygen during labor and delivery. Spina bifida (Choice A) is a neural tube defect that occurs during embryonic development and is not directly caused by anoxia during labor. Anencephaly (Choice B) is a severe neural tube defect where the baby is born without parts of the brain and skull, not typically caused by anoxia during labor. Muscular dystrophy (Choice D) is a genetic disorder characterized by progressive muscle weakness and is not directly related to anoxia during labor and delivery.

3. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.

• A. T cells
• B. B cells
• C. telomeres
• D. antigens

Correct answer: D

Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.

4. When Reggie takes his baby son, Tyson, to his workplace for the first time, Reggie's assistant abruptly picks Tyson up and walks around the office. Tyson cries and reaches out for Reggie. Tyson is expressing __________.

• A. sadness
• B. stranger anxiety
• C. separation anxiety
• D. disgust

Correct answer: B

Rationale: Tyson is experiencing stranger anxiety in this situation. Stranger anxiety is a common response in infants when they are exposed to unfamiliar people, causing distress and prompting the infant to seek comfort and familiarity, usually from their primary caregiver. This aligns with Tyson crying and reaching out for Reggie, as he is showing signs of discomfort and wariness towards the assistant, who is a stranger to him. Choice A, sadness, does not fit the scenario as Tyson's reaction is more related to fear and discomfort rather than sorrow. Choice C, separation anxiety, is not the correct answer in this context as separation anxiety pertains to distress when separated from a primary caregiver, not when encountering unfamiliar individuals. Choice D, disgust, is also not applicable as Tyson's behavior is not based on revulsion but rather on being in an unfamiliar and distressing situation.

5. T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's __________.

• A. risk for developmental problems
• B. ability to comply with parental commands and responsiveness to touch
• C. reflexes, muscle tone, state changes, and responsiveness to stimulation
• D. heart rate, respiratory effort, reflex irritability, muscle tone, and color

Correct answer: C

Rationale: T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's reflexes, muscle tone, state changes, and responsiveness to stimulation. This assessment helps healthcare providers understand the newborn's behavioral responses and capabilities in various areas, providing valuable insights into their overall development and well-being. Choices A, B, and D are incorrect because the NBAS focuses on assessing the newborn's behavioral responses and capabilities, rather than their risk for developmental problems, compliance with commands, or physiological parameters like heart rate and respiratory effort.
