1. 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.

2. Babies who spend more time alert are likely to have __________.

• A. parents who feel incompetent
• B. a slight advantage in mental development
• C. a big disadvantage in social development
• D. parents who must exert great effort to soothe them

Correct answer: B

Rationale: Babies who spend more time alert are likely to have a slight advantage in mental development. Being alert allows babies to engage with their surroundings, explore, and learn, which can contribute to their cognitive development. This is different from social development, which is more related to interactions with others, and not necessarily impacted by the amount of alertness a baby displays. Choices A, C, and D are incorrect because there is no direct correlation between a baby's alertness and their parents' feelings of incompetence, a big disadvantage in social development, or the effort parents need to soothe them.

3. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.

• A. heavier but shorter
• B. heavier and longer
• C. lighter but longer
• D. lighter and shorter

Correct answer: B

Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.

4. T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's __________.

• A. risk for developmental problems
• B. ability to comply with parental commands and responsiveness to touch
• C. reflexes, muscle tone, state changes, and responsiveness to stimulation
• D. heart rate, respiratory effort, reflex irritability, muscle tone, and color

Correct answer: C

Rationale: T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's reflexes, muscle tone, state changes, and responsiveness to stimulation. This assessment helps healthcare providers understand the newborn's behavioral responses and capabilities in various areas, providing valuable insights into their overall development and well-being. Choices A, B, and D are incorrect because the NBAS focuses on assessing the newborn's behavioral responses and capabilities, rather than their risk for developmental problems, compliance with commands, or physiological parameters like heart rate and respiratory effort.

5. __________ may heighten the effects of a high-fat diet.

• A. Sex hormones
• B. Over-the-counter medications
• C. Free radicals
• D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.
