1. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?
- A. The negative effects of smoking are only evident in children born to heavy smokers.
- B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
- C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
- D. The effects of passive smoking are not yet known.
Correct answer: B
Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.
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. Ecological systems theory views the person as __________.
- A. a blossoming flower whose development is a genetically determined series of events that unfold automatically
- B. developing within a complex system of relationships affected by multiple levels of the surrounding environment
- C. a social being influenced primarily by observational learning or adult modeling
- D. a computer-like system that actively codes, transforms, and organizes information
Correct answer: B
Rationale: Ecological systems theory views the person as developing within a complex system of relationships affected by multiple levels of the surrounding environment. This perspective emphasizes the interconnectedness of individuals with their social and physical environment, recognizing that development is influenced by various factors interacting at different levels of the ecological system. Choice A is incorrect because it describes a genetically determined development process, which is not the focus of ecological systems theory. Choice C is incorrect because it highlights observational learning as the primary influence on development, neglecting the broader environmental factors. Choice D is incorrect as it compares the person to a computer system, which does not align with the principles of ecological systems theory.
4. In developing countries, the most readily available intervention for promoting the recovery of preterm babies is _________.
- A. hospitalization
- B. care in an isolette
- C. lying on a waterbed
- D. skin-to-skin 'kangaroo care'
Correct answer: D
Rationale: In developing countries, the most readily available intervention for promoting the recovery of preterm babies is skin-to-skin 'kangaroo care.' This involves direct skin-to-skin contact between the baby and a caregiver, typically the mother, which helps regulate the baby's body temperature, improve bonding, and support overall development. Kangaroo care can be easily implemented even in resource-limited settings and has been shown to have positive effects on preterm infants' health outcomes. Choices A, B, and C are incorrect because hospitalization, care in an isolette, and lying on a waterbed are not specifically tailored interventions that address the unique needs of preterm babies in developing countries like kangaroo care does.
5. In the eighth month of pregnancy, what typically happens?
- A. fetal growth doubles
- B. neuron production increases
- C. the eyes, ears, nose, jaw, and neck form
- D. lanugo typically is shed
Correct answer: D
Rationale: In the eighth month of pregnancy, lanugo typically is shed. Lanugo is the fine, downy hair that covers a fetus's body to help regulate body temperature while in the womb. By the eighth month, many fetuses shed this hair as they prepare for birth. Choices A, B, and C are incorrect because fetal growth doubling, neuron production increasing, and the formation of eyes, ears, nose, jaw, and neck occur in earlier stages of pregnancy, not specifically in the eighth month.
