1. Which factor disrupts the brain's regulation of hunger and metabolism?

• A. Self-regulation
• B. Frequent eating out
• C. Reduced sleep
• D. Using screen media

Correct answer: C

Rationale: Reduced sleep is the correct answer as it affects hormones that regulate hunger and metabolism, leading to increased appetite and weight gain. Self-regulation is not directly related to the brain's regulation of hunger and metabolism. Frequent eating out may impact food choices and portion sizes but is not specifically linked to disrupting the brain's regulation. Using screen media can affect sleep patterns but is not as directly related to the brain's regulation of hunger and metabolism as reduced sleep.

2. Currently, the most widely used potent teratogen is __________.

• A. aspirin
• B. diethylstilbestrol (DES)
• C. thalidomide
• D. isotretinoin

Correct answer: D

Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.

3. Three-month-old Jefferson will probably listen longer to __________ than to __________.

• A. pure tones; voices
• B. pure tones; noises
• C. human speech; nonspeech sounds
• D. a foreign language; his native language

Correct answer: C

Rationale: Three-month-old Jefferson will likely listen longer to human speech compared to nonspeech sounds because infants have a natural preference for speech sounds. This preference is believed to be attributed to their biological readiness to learn language and communicate with others. Choice A is incorrect because voices are a form of human speech, which is preferred over pure tones. Choice B is incorrect as noises do not necessarily engage infants' attention as effectively as human speech. Choice D is incorrect because Jefferson is more likely to listen longer to his native language rather than a foreign language at this early age.

4. 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.

5. Which statement about prenatal rubella is true?

• A. The greatest damage occurs when rubella strikes during the fetal period.
• B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems. Copyright © 2018 Laura E. Berk. All Rights Reserved. 15 Test Bank for Berk, Development Through the Lifespan, 7e
• C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
• D. Infection during the embryonic period is less harmful than during other prenatal periods. Answer: B Page Ref: 86‒87 Skill Level: Understand known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.
