Growth and Development Exam

1. The yolk sac __________.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.

Correct answer: C

Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.

3. When Mateo was born prematurely to Yvonne, a cocaine addict, what can his caregivers expect?

Correct answer: B

Rationale: Mateo, being born prematurely to a cocaine-addicted mother, is at risk for several health issues. One common effect of prenatal drug exposure is a higher likelihood of sensory and regulatory problems, such as having abnormally shrill and piercing cries. This is a potential outcome that Mateo's caregivers can expect due to his circumstances. Choice A is incorrect as there is no direct correlation between being born prematurely to a cocaine-addicted mother and being very attentive to the environment. Choice C is incorrect as overcoming harmful effects of drug exposure by age 3 is overly optimistic and may not be the case for all children exposed to drugs prenatally. Choice D is incorrect as rapid motor development is not typically associated with prenatal drug exposure.

4. Critics worry that fetal monitoring __________.

Correct answer: C

Rationale: Critics worry that fetal monitoring may identify babies as in danger who, in fact, are not. This can lead to unnecessary interventions and stress for the parents. It is important to carefully consider the accuracy and benefits of fetal monitoring to avoid unnecessary harm to both the mother and the baby. Choice A is incorrect because fetal monitoring does not cause numbness in the lower half of the body. Choice B is incorrect as fetal monitoring is helpful in detecting hidden problems with the baby. Choice D is incorrect as there is no direct link between fetal monitoring and an increased likelihood of infant brain damage.

5. Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?

Correct answer: C

Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.
