Growth and Development Exam

1. A 20-week-old fetus can __________.

A. be stimulated as well as irritated by sounds
B. survive, if born early
C. breathe without oxygen assistance, if born early
D. control its own body temperature Answer: A Page Ref: 80 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.

2. A major strength of the information-processing approach to development is its commitment to __________.

A. the study of imagination
B. flexible case study interviews
C. rigorous research methods
D. disproving other developmental theories

Correct answer: C

Rationale: The major strength of the information-processing approach to development is its commitment to rigorous research methods. This approach emphasizes systematic observation, measurement, and experimentation to study cognitive development in individuals. By using rigorous research methods, researchers can gather reliable and valid data to better understand how information is processed in the human mind. This commitment to methodological rigor enhances the credibility and validity of the conclusions drawn within the information-processing approach to development. Choices A, B, and D are incorrect because the information-processing approach focuses on empirical research methods rather than the study of imagination, case study interviews, or disproving other developmental theories.

3. Fetal monitoring is __________.

A. rarely used in U.S. hospitals
B. linked with low birth weight
C. linked with a decreased rate of cesarean deliveries
D. required in most U.S. hospitals

Correct answer: D

Rationale: Fetal monitoring is required in most U.S. hospitals during labor and delivery to track the baby's heart rate and the mother's contractions. This helps healthcare providers to assess the well-being of the fetus and make timely decisions regarding the need for interventions if any complications arise. Choices A, B, and C are incorrect because fetal monitoring is a standard procedure in most hospitals to ensure the safety and health of both the mother and the baby during labor.

4. What is one challenge associated with longitudinal research?

A. It does not allow for inferences about cause-and-effect relationships.
B. Participants may relocate or drop out of the study.
C. Findings may not be applicable to real-world scenarios.
D. It does not allow for the examination of individual developmental patterns.

Correct answer: B

Rationale: One challenge associated with longitudinal research is that participants may relocate or drop out of the study over time. This can result in missing data and potential biases in the findings, impacting the study's overall validity and reliability. Furthermore, it can present difficulties for researchers in accurately monitoring and analyzing changes in individuals over an extended period. Options A, C, and D are incorrect because longitudinal research can indeed allow for inferences about cause-and-effect relationships, findings can be generalized to the real world with appropriate design and sampling, and it is suitable for studying individual developmental patterns.

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

A. He will be very attentive to the environment
B. His cries will be abnormally shrill and piercing
C. He will overcome the harmful effects of drug exposure by age 3
D. His motor development will be especially rapid during the first year

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.
