1. Breastfeeding for just a few weeks ________.
- A. is a rare practice among American women
- B. leads directly to later obesity
- C. is not helpful because, in the beginning, breastfeeding causes constipation
- D. offers some protection against respiratory and intestinal infections
Correct answer: D
Rationale: Breastfeeding for even a short period offers infants protection against respiratory and intestinal infections. Choice A is incorrect because breastfeeding is not a rare practice among American women. Choice B is incorrect as there is no direct link between breastfeeding for a few weeks and later obesity. Choice C is incorrect as breastfeeding does not cause constipation in infants; in fact, it can help prevent constipation.
2. During prenatal development, the ectoderm becomes the __________.
- A. muscles and skeleton
- B. nervous system and skin
- C. circulatory system and other internal organs
- D. digestive system, lungs, urinary tract, and glands
Correct answer: B
Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.
3. Cindy tells her daughter, “I know you can do a good job on that homework†because she believes that if she encourages persistence, her daughter will start to view herself as hardworking and high-achieving. Cindy is applying the __________ approach.

4. During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.
- A. premature labor
- B. limb deformities
- C. respiratory distress at birth
- D. low birth weight Answer: D Page Ref: 83 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Difficult
Correct answer: D
Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.
5. The most rapid prenatal changes take place in the period of the __________.
- A. zygote
- B. blastocyst
- C. embryo
- D. fetus
Correct answer: C
Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.
