Human Growth and Development Final Exam

1. In the __________ period, teratogens rarely have any impact.

Correct answer: A

Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.

2. Typical parents give their sons toys that emphasize __________.

Correct answer: C

Rationale: The correct answer is C: 'competition.' Parents often give boys toys that promote competition and physical activity, aligning with traditional gender roles. This emphasis on competition can help boys develop skills such as leadership, strategy, and resilience. Choice A, 'cooperation,' is incorrect because while cooperation is valuable, it is not typically emphasized through toys given to boys. Choice B, 'nurturance,' is also incorrect as nurturing qualities are not commonly associated with toys given to boys. Choice D, 'physical attractiveness,' is unrelated to the toys parents usually give their sons.

3. __________, especially, are more insistent that __________ conform to gender roles.

Correct answer: D

Rationale: The correct answer is D: 'Fathers; boys.' The extract provided indicates that fathers are particularly insistent that boys adhere to traditional gender roles, emphasizing masculinity. This is a common stereotype where fathers often push their sons to conform to societal expectations of masculinity. Choices A and B are incorrect because the extract specifies fathers, not mothers. Choice C is incorrect as it pairs fathers with girls, which is not supported by the provided information.

4. The __________ reflex helps a newborn find the nipple.

Correct answer: A

Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.

5. This means that Andrew __________.

Correct answer: B

Rationale: The statement "Andrew needs assistance in establishing breathing and other vital signs" refers to the initial steps taken to ensure a newborn's well-being after birth. This is a common practice to ensure that the newborn is transitioning smoothly into the outside world and is not indicative of a serious danger that requires emergency medical attention.
