Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.
- A. a burst of motor activity
- B. a period of sleep
- C. a rise in Liz's heart rate
- D. a drop in Liz's body temperature
Correct Answer: A
Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership __________ than comparison-group agemates.
- A. scored lower in impulsivity and overactivity
- B. had lower academic achievement scores
- C. showed more aggressive behavior
- D. reported less alcohol and drug use

Although Justin spent his first 18 months in an orphanage, his adoptive mother believes that sensitive caregiving will help Justin overcome his early experiences. Justin's mother emphasizes the role of __________ in development.
- A. nurture
- B. stages
- C. stability
- D. nature
Correct Answer: A

In this scenario, Justin's adoptive mother believes that providing sensitive caregiving will override the negative effects of his early experiences in the orphanage, highlighting the importance of nurture in promoting healthy development. Choice B, stages, is incorrect as it refers to the sequence of developmental milestones individuals pass through. Choice C, stability, is incorrect as it pertains to the consistency of behavior or development over time. Choice D, nature, is incorrect as it relates to genetic and biological factors influencing development, which is not the focus of Justin's mother's beliefs.
The mother feels a natural urge to squeeze and push with her abdominal muscles during which stage of labor?
- A. first
- B. second
- C. third
- D. fourth
Correct Answer: B
Rationale: The mother feels a natural urge to squeeze and push with her abdominal muscles during the second stage of labor. This stage occurs after the cervix is fully dilated and ends with the delivery of the baby. Choice A (first) is incorrect as the first stage is mainly characterized by the dilation of the cervix. Choice C (third) is incorrect as the third stage is the delivery of the placenta, and choice D (fourth) is incorrect as the fourth stage is the recovery period after childbirth.
Despite growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father, Betty is a successful, happy, and healthy adult. Betty's ability to adapt effectively in the face of threats to development is known as __________.
- A. assimilation
- B. resilience
- C. age-graded development
- D. multidimensional development
Correct Answer: B
Rationale: Betty's ability to adapt effectively despite facing challenges during her childhood such as growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father demonstrates resilience. Resilience refers to the capacity to achieve positive outcomes despite adverse circumstances. Betty's successful, happy, and healthy adulthood showcases her resilience in navigating and overcoming the threats to her development.
Choice A, assimilation, does not fit the context of adapting effectively to adverse circumstances. Assimilation is a cognitive process related to incorporating new information into existing schemas. Choice C, age-graded development, refers to typical developmental changes that occur in a culture at a particular age. Choice D, multidimensional development, encompasses the idea that development is influenced by multiple factors across various dimensions, which is not directly related to Betty's ability to adapt effectively despite facing challenges.
Swaddling newborns __________.
- A. increases crying
- B. hinders early motor development
- C. promotes an insecure attachment relationship
- D. restricts movement and increases warmth
Correct Answer: D
Rationale: Swaddling newborns restricts their movement by wrapping them snugly in a blanket, which helps to mimic the feeling of security they had in the womb. It also helps to maintain their warmth and can promote better sleep patterns. Choices A, B, and C are incorrect because swaddling does not increase crying, hinder early motor development, or promote an insecure attachment relationship. Instead, it provides comfort, warmth, and a sense of security for newborns.
