__________ doubles the risk of SIDS.

Correct Answer: D

Rationale: In this scenario, the correct answer is D) Cigarette smoking by a caregiver. This is because exposure to cigarette smoke has been identified as a significant risk factor for Sudden Infant Death Syndrome (SIDS). Cigarette smoke contains harmful chemicals that can impair an infant's respiratory and cardiovascular systems, making them more vulnerable to SIDS. Option A) Failure to tightly swaddle an infant during sleep is incorrect because swaddling is a common practice to provide comfort and security to infants during sleep, and when done correctly, it does not increase the risk of SIDS. Option B) Using a pacifier or a security blanket is actually recommended to reduce the risk of SIDS. These items can help soothe the infant and promote safe sleep practices. Option C) Placing an infant to sleep on his back is the recommended position to reduce the risk of SIDS. This is a crucial safe sleep practice that has been widely promoted to prevent SIDS. Educationally, understanding the risk factors associated with SIDS is essential for healthcare professionals working with infants and their caregivers. By knowing which factors increase the risk of SIDS, healthcare providers can educate parents and caregivers on how to create a safe sleep environment for infants, ultimately helping to prevent this tragic outcome. It is crucial to communicate the dangers of cigarette smoke exposure to infants and emphasize the importance of maintaining a smoke-free environment to protect the infant's health and well-being.

Correct Answer: C

Rationale: In the context of newborn development, the correct answer is C) Vision. Newborn babies are born with their sense of vision being the least developed among their senses. This is due to the fact that their visual system is not fully mature at birth, and it takes time for them to develop the ability to focus, track objects, and perceive depth and colors accurately. Option A) Taste, Option B) Sound, and Option D) Touch are more developed senses at birth compared to vision. Babies have the ability to taste and differentiate flavors, hear sounds in the environment, and feel sensations through touch right from birth. These senses play crucial roles in helping newborns interact with their environment and caregivers. Understanding the hierarchy of sensory development in newborns is essential for healthcare professionals, caregivers, and educators working with infants. By recognizing that vision is the least developed sense, they can provide appropriate stimuli and support to help infants gradually enhance their visual abilities as they grow and develop.

Correct Answer: D

Rationale: The correct answer is D because the statement aligns with the concept of reciprocal influences in human development. The new evidence suggests that individuals are not only influenced by the contexts in which they develop but also contribute to shaping those contexts. This idea highlights the dynamic and interactive nature of human development, emphasizing the bidirectional relationship between individuals and their environments.

Correct Answer: D

Rationale: Increasingly, researchers see development as a perpetually ongoing process. This perspective emphasizes that development continues throughout the lifespan, rather than stopping at a particular age like adolescence. Researchers now focus on understanding how individuals change and grow over time, recognizing that development is a lifelong journey influenced by both biological and environmental factors.

Correct Answer: B

Rationale: People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to history-graded influences. These influences refer to the events and conditions that are common to a particular historical era and can significantly shape the development and experiences of individuals who live through them. The post-World War II era, economic prosperity, and social changes during the baby boom period are examples of historical events that have had a lasting impact on this generation.
