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. Dr. Faulkner believes that directly observable events, such as stimuli and responses, are the appropriate focus of the study of development. Dr. Faulkner probably follows the __________ perspective of development.

• A. psychosexual
• B. psychosocial
• C. behaviorist
• D. cognitive-developmental

Correct answer: C

Rationale: Dr. Faulkner's focus on directly observable events, such as stimuli and responses, aligns with the behaviorist perspective of development. Behaviorism emphasizes the influence of the environment on individual behavior and learning, with a strong emphasis on observable actions rather than internal mental processes or stages of development. Choice A, psychosexual, is associated with Freud's theory focusing on stages of psychosexual development. Choice B, psychosocial, is linked to Erikson's theory of psychosocial development. Choice D, cognitive-developmental, is related to Piaget's theory emphasizing cognitive development stages.

3. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?

• A. The negative effects of smoking are only evident in children born to heavy smokers.
• B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
• C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
• D. The effects of passive smoking are not yet known.

Correct answer: B

Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.

4. Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?

• A. regular sleep
• B. drowsiness
• C. irregular sleep
• D. quiet alertness

Correct answer: C

Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.

5. 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.
