when the blastocyst burrows deep into the uterine lining

ATI RN

Human Growth and Development Final Exam

1. When the blastocyst burrows deep into the uterine lining, __________.

A. implantation occurs
B. pregnancy does not occur
C. it stops growing
D. the cells of the zygote first duplicate

Correct answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.

2. According to the lifespan perspective, _______ is supreme in its impact on the life course.

A. the prenatal period
B. early childhood
C. adolescence
D. no age period

Correct answer: D

Rationale: According to the lifespan perspective, no single period is considered supreme in its impact on the life course. Each stage of life, from prenatal period through adulthood, plays a significant role in shaping an individual's development. Therefore, the correct answer is 'D: no age period.' Choices A, B, and C are incorrect because the lifespan perspective emphasizes that all stages are important and contribute uniquely to an individual's life course.

3. Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had __________.

A. taught women to fear the birth experience
B. helped women develop breathing techniques to lessen the pain of labor
C. taught women that medical intervention was unnecessary in childbirth
D. helped women focus on child rearing rather than childbirth

Correct answer: A

Rationale: Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had taught women to fear the birth experience. They believed that this fear contributed to increased pain during labor and advocated for methods to reduce fear and promote relaxation during childbirth. Choice B is incorrect as the focus is on fear, not on techniques to lessen pain. Choice C is incorrect as the experts did not advocate against medical intervention but rather against unnecessary fear. Choice D is incorrect as the experts aimed to change attitudes towards childbirth, not redirect focus to child rearing.

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. 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.
