1. 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.

2. What is the longest stage of labor?

• A. Delivery of the baby
• B. Delivery of the placenta
• C. Dilation and effacement of the cervix
• D. Release of epinephrine and cortisol

Correct answer: C

Rationale: The correct answer is C: Dilation and effacement of the cervix. This stage can last for hours, especially for first-time mothers, as the cervix needs to dilate and efface to allow for the baby's passage through the birth canal. Once the cervix is fully dilated and effaced, the woman can begin pushing during the second stage of labor to deliver the baby. The delivery of the baby itself is usually a shorter process compared to the time taken for the cervix to dilate and efface. Choices A, B, and D are incorrect because they represent other stages within the labor process that come after the dilation and effacement of the cervix.

3. Children in middle childhood are in Piaget's _______ stage, which extends from about 7 to 11 years.

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. formal operational

Correct answer: C

Rationale: The correct answer is C: concrete operational. During the concrete operational stage, children start to engage in logical thinking about concrete events. This stage typically occurs between the ages of 7 to 11 years. Choices A, B, and D are incorrect. The sensorimotor stage (choice A) is the first stage in Piaget's theory, occurring from birth to about 2 years old. The preoperational stage (choice B) follows the sensorimotor stage and occurs roughly from ages 2 to 7 years. The formal operational stage (choice D) is the final stage in Piaget's theory, where abstract thinking and hypothetical reasoning develop, usually beginning around age 11.

4. Theorists who contend that powerful negative events in the first few years cannot be fully overcome by later, more positive ones emphasize __________.

• A. plasticity
• B. stability
• C. nurture
• D. discontinuity

Correct answer: B

Rationale: Theorists who emphasize stability argue that powerful negative events early in life cannot be completely overcome by later, more positive experiences. They believe that early experiences have a lasting impact on development and are not easily erased or reversed by subsequent events. This perspective contrasts with the idea of plasticity, which suggests that development can be influenced by experiences at any point in life, and that individuals have the capacity for change and growth throughout the lifespan. 'Nurture' does not directly address the concept of overcoming negative events, while 'discontinuity' refers to developmental stages being separate and distinct, not the idea that negative events early in life persist despite later positive experiences.

5. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.

• A. is harmful only when combined with other teratogens
• B. can increase the risk of childhood cancer
• C. rarely causes lasting damage
• D. is safe during the last trimester

Correct answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.
