ATI RN

Human Growth and Development Final Exam

1. Recent evidence suggests that paternal alcohol use around the time of conception __________.

A. can alter gene expression
B. can cause fetal alcohol syndrome
C. is linked to blood vessel abnormalities
D. has no negative effect on the developing organism

Correct answer: A

Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.

2. Under ethical standards, when is deception permitted in research studies?

A. if the participants are young enough that they would not understand the deception
B. if investigators satisfy institutional review boards that such practices are necessary
C. if researchers can observe participants from behind one-way mirrors
D. if the participants give informed consent and the researchers never reveal the real purpose of the study

Correct answer: B

Rationale: Ethical standards permit deception in research studies if investigators satisfy institutional review boards that such practices are necessary. Institutional review boards are responsible for ensuring that research studies comply with ethical guidelines and protect the welfare of study participants. Deception should only be used when necessary, and the board's approval indicates that safeguards are in place to minimize harm to participants. Choices A, C, and D are incorrect because ethical deception in research studies is not based on the age of participants, observing from behind mirrors, or obtaining informed consent without revealing the study's real purpose.

3. What is one strength of the cross-sectional design?

A. It provides evidence about individual trends.
B. It cannot be threatened by cohort effects.
C. It is not plagued with dropout or practice effects.
D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate

Correct answer: C

Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.

4. Dr. Redmund characterizes his view of development as a bioecological model. His perspective is aligned with that of which theorist?

A. Jean Piaget
B. Urie Bronfenbrenner
C. Lev Vygotsky
D. Niko Tinbergen

Correct answer: B

Rationale: Dr. Redmund's view of development aligns with the bioecological model, which is associated with Urie Bronfenbrenner. This model emphasizes the interaction between an individual's biological characteristics and environmental influences in development. Jean Piaget's theory focuses on cognitive development, Lev Vygotsky's theory emphasizes social interactions, and Niko Tinbergen is known for his work in animal behavior and instinct, not human development. Therefore, the correct answer is Urie Bronfenbrenner (Choice B).

5. During the third stage of labor, __________.

A. the cervix thins to nothing
B. uterine contractions begin
C. the placenta is delivered
D. the baby is born

Correct answer: C

Rationale: During the third stage of labor, the correct answer is C, the placenta is delivered. This stage occurs after the baby is born and involves the expulsion of the placenta from the uterus. Choice A is incorrect because the thinning of the cervix to nothing typically occurs during the first stage of labor. Choice B is incorrect as uterine contractions usually begin during the first stage of labor to help with the dilation of the cervix. Choice D is incorrect because the baby is typically born in the second stage of labor, not the third.
