Human Growth and Development Exam 1

1. Jalynn is in the last half of the first month of her pregnancy. Which of the following is developing the fastest?

A. circulatory system
B. endocrine system
C. nervous system
D. skin

Correct answer: C

Rationale: During the last half of the first month of pregnancy, the nervous system develops the fastest among the options provided. This rapid development of the nervous system is crucial for the overall growth and functioning of the fetus. The nervous system includes the brain and spinal cord, which are essential for various bodily functions and will continue to develop throughout the pregnancy. The circulatory system, although important, does not develop at the fastest rate during this stage. The endocrine system and skin also play significant roles in the development of the fetus but are not the systems that develop the fastest in the last half of the first month of pregnancy.

2. In the last weeks of pregnancy, __________.

A. the fetus usually loses weight
B. most fetuses assume an upside-down position
C. fetal growth increases dramatically
D. the fetus relies on its own well-developed immune system

Correct answer: B

Rationale: In the last weeks of pregnancy, most fetuses assume an upside-down position known as the head-down position or vertex presentation. This position is ideal for a smoother labor and delivery process as it helps the baby move through the birth canal. Fetal growth has already slowed down at this stage, so option C is incorrect. Option A is inaccurate as the fetus typically gains weight in the final weeks. Option D is incorrect because the fetus relies on the mother's immune system while in the womb.

3. According to Erikson, when parents are over- or undercontrolling, the outcome is a child who __________.

A. feels forced and shamed
B. acts competently on his own
C. asserts his independence
D. feels self-confident

Correct answer: A

Rationale: According to Erikson, when parents are over- or undercontrolling, the outcome is a child who feels forced and shamed. This is because overly controlling parents can make the child feel inadequate, leading to a sense of shame and doubt. Choice B, 'acts competently on his own,' is incorrect because overcontrolling parents hinder the child's ability to act independently. Choice C, 'asserts his independence,' is incorrect because overcontrolling parents can actually suppress the child's independence. Choice D, 'feels self-confident,' is incorrect because overcontrolling parenting can undermine the child's confidence and lead to feelings of inadequacy.

4. A baby born between the seventh and eighth months of pregnancy __________.

A. is just as healthy as a full-term baby
B. usually needs oxygen assistance to breathe
C. only has about a 10 percent survival rate
D. is considered small-for-date

Correct answer: B

Rationale: A baby born between the seventh and eighth months of pregnancy is considered premature. Premature babies are born before they are fully developed and may need assistance with breathing, including oxygen. They are at a higher risk for complications compared to full-term babies. Choice A is incorrect because premature babies are at a higher risk for health issues compared to full-term babies. Choice C is incorrect as modern medical advancements have significantly increased the survival rate of premature babies. Choice D is incorrect as being small-for-date does not solely depend on the gestational age at birth.

5. Which statement about the human immunodeficiency virus (HIV) is true?

A. About 30 percent of all new HIV infections affect women.
B. In South Africa, 30 percent of all pregnant women are HIV-positive.
C. About 30 percent of new HIV infections occur in developing countries.
D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.
