1. Regarding a baby’s adaptation to labor and delivery, stress hormones __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 21 Test Bank for Berk, Development Through the Lifespan, 7e

• A. endanger the newborn
• B. arouse the infant into alertness
• C. cause the cervix to thin and the uterine wall to contract
• D. cause the mother to breathe deeply, increasing the infant’s oxygen supply Answer: B Page Ref: 94 Skill Level: Understand newborn baby’s appearance. Topic: Childbirth Difficulty Level: Moderate

Correct answer: B

Rationale: Stress hormones during labor and delivery actually help arouse the infant into alertness. These hormones can promote the infant's readiness to adapt to the new environment outside the womb.

2. Which statement about epidural analgesia is true?

• A. It numbs the entire lower half of the body.
• B. It limits pain reduction to the pelvic region.
• C. It strengthens uterine contractions.
• D. It shortens the length of labor.

Correct answer: B

Rationale: The correct statement about epidural analgesia is that it limits pain reduction to the pelvic region by blocking nerve signals from that specific area, providing pain relief during labor and delivery. Choice A is incorrect because epidural analgesia does not numb the entire lower half of the body. Choice C is incorrect because epidural analgesia does not strengthen uterine contractions; in fact, it may sometimes weaken them. Choice D is incorrect because epidural analgesia does not shorten the length of labor; it can sometimes prolong labor.

3. During the second trimester, a white, cheeselike substance called __________ emerges on the skin.

• A. lanugo
• B. corpus luteum
• C. vernix
• D. chorion

Correct answer: C

Rationale: During the second trimester of pregnancy, a white, cheeselike substance called vernix emerges on the skin of the developing fetus. Vernix is a protective layer that helps prevent the skin from becoming waterlogged during the time in the amniotic fluid. Choice A, lanugo, is incorrect as lanugo refers to the fine, soft hair that covers the body of a fetus. Choice B, corpus luteum, is incorrect as it is a temporary endocrine structure involved in the menstrual cycle. Choice D, chorion, is incorrect as it is one of the membranes that surround the embryo and later the fetus.

4. During the period of the embryo, the __________ becomes the __________.

• A. mesoderm; nervous system, lungs, internal organs, and skin
• B. chorion; endocrine system, muscles, placenta, and skeleton
• C. ectoderm; circulatory system, skin, skeleton, and internal organs
• D. endoderm; digestive system, lungs, urinary tract, and glands Answer: D Page Ref: 78 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: D

Rationale: During the period of the embryo, the endoderm becomes the digestive system, lungs, urinary tract, and glands. The endoderm is one of the primary germ layers that give rise to various internal organs in the developing embryo. It plays a crucial role in the formation of organs such as the digestive system, respiratory system, and glandular structures.

5. To study the impact of biological aging on motor skills, researchers focus on __________.

• A. sedentary adults
• B. competitive athletes
• C. men in their mid- to late thirties
• D. women in their childbearing years

Correct answer: B

Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.
