Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?

Correct Answer: C

Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.

Correct Answer: D

Rationale: At around 4 months of age, babies begin to develop a preference for salty taste over plain water. This preference is part of their sensory development and exploration of tastes. Introducing a variety of flavors, including salty tastes, at this stage helps broaden the baby's palate and acceptance of different foods later on. Choices A, B, and C are incorrect as babies typically do not develop a preference for salty tastes over plain water at 2 weeks, 6 weeks, or 2 months of age. These earlier stages are more focused on milk feeding and the introduction of solid foods usually begins around 4-6 months of age.

Correct Answer: C

Rationale: T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's reflexes, muscle tone, state changes, and responsiveness to stimulation. This assessment helps healthcare providers understand the newborn's behavioral responses and capabilities in various areas, providing valuable insights into their overall development and well-being. Choices A, B, and D are incorrect because the NBAS focuses on assessing the newborn's behavioral responses and capabilities, rather than their risk for developmental problems, compliance with commands, or physiological parameters like heart rate and respiratory effort.

Correct Answer: D

Rationale: The correct answer is D. According to the continuous view of development, the difference between the immature and the mature is seen as simply one of amount or complexity. This view suggests that development is a gradual and continuous process where individuals steadily acquire new abilities without abrupt changes or stages. Choices A, B, and C are incorrect because nature, discontinuous, and nurture do not align with the description provided in the question. Nature typically refers to genetic or biological factors, discontinuous implies stages or abrupt changes, and nurture relates to environmental influences, none of which are synonymous with the continuous view of development.

Correct Answer: A

Rationale: The correct answer is A, nurture. Nurture refers to the environmental influences that shape behavior and development. 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.
