1. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.

• A. mesoderm; neuron tract
• B. neural tube
• C. endoderm; neural tube
• D. neuron tract

Correct answer: B

Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.

2. What is the best-known effect of smoking during the prenatal period?

• A. Colic
• B. Respiratory distress at birth
• C. Low birth weight
• D. Delayed language development

Correct answer: C

Rationale: The best-known effect of smoking during the prenatal period is low birth weight. Smoking during pregnancy is a known teratogen that can lead to negative outcomes for the developing fetus, such as growth restrictions resulting in low birth weight. This condition can have significant long-term consequences on the child's health and development. Choices A, B, and D are incorrect as they are not the primary effect associated with smoking during the prenatal period. Colic is typically associated with digestive issues, respiratory distress at birth can be caused by various factors other than smoking, and delayed language development is not directly linked to smoking during pregnancy.

3. Mothers who __________ have fewer birth complications and shorter labors.

• A. choose cesarean delivery
• B. give birth at home
• C. are supported by a trained companion during childbirth
• D. are administered epidural analgesia during childbirth

Correct answer: C

Rationale: According to research, mothers who are supported by a trained companion during childbirth have fewer birth complications and shorter labors. This support can reduce stress and anxiety levels, provide comfort and encouragement, and help the mother feel more in control during labor and delivery. Overall, having a trained companion present can contribute to a more positive childbirth experience for the mother. Choices A, B, and D are incorrect because they do not align with the research findings that specifically highlight the benefits of having a trained companion during childbirth.

4. Observations of imprinting led to which major concept in human development?

• A. adaptation
• B. equilibrium
• C. the critical period
• D. classical conditioning

Correct answer: C

Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.

5. What is the most common approach to controlling pain during labor?

• A. an anesthetic
• B. a spinal block
• C. fetal monitoring
• D. epidural analgesia

Correct answer: D

Rationale: Epidural analgesia is the most common approach to controlling pain during labor. It involves the administration of pain medication through a catheter placed in the epidural space of the spine, providing pain relief while allowing the mother to remain alert and participate in the birthing process. It is preferred by many women due to its effectiveness in reducing labor pain. Choices A, B, and C are incorrect as they do not directly address pain management during labor. While an anesthetic and a spinal block are forms of pain relief, epidural analgesia is specifically the most common method used for pain control during labor.
