Growth and Development Exam

1. An inadequate diet during pregnancy can __________.

A. lead to higher birth weight and greater brain weight
B. reduce the risk of pregnancy-induced maternal diabetes
C. distort the structure of the liver, kidney, and pancreas
D. lead to fewer physical discomforts in the final weeks Answer: C Page Ref: 88 Skill Level: Understand Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: C

Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.

2. __________ 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.

3. Spatial skills __________.

A. increase exponentially in early childhood
B. support children's improved executive function
C. develop gradually over childhood and adolescence
D. are typically housed in the left hemisphere

Correct answer: C

Rationale: Spatial skills develop gradually over childhood and adolescence, reflecting the increasing complexity of these abilities. Choice A is incorrect because spatial skills do not increase exponentially in early childhood but rather develop steadily. Choice B is incorrect as spatial skills are not directly linked to executive function. Choice D is incorrect because spatial skills are not typically housed in a specific hemisphere but involve a network of brain regions.

4. 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.

5. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.

A. lower birth weight and higher risk of premature birth
B. suppressed development of the immune system
C. serious damage to the central nervous system
D. improved fetal cardiovascular functioning

Correct answer: D

Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.
