Human Growth and Development Exam Questions

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: B

Rationale: Ethnographic research is directed toward understanding a culture through participant observation. This type of observation involves the researcher immersing themselves in the culture being studied, actively participating in the daily activities and interactions of the group being studied. Through participant observation, researchers can gain a deep and nuanced understanding of the culture from the inside. Choice A, naturalistic observation, typically refers to observing subjects in their natural environment without interference, but it does not involve actively participating in the culture. Choice C, systematic observation, focuses on carefully planned and structured data collection methods but may not involve direct participation. Choice D, structured observation, implies a predefined set of guidelines for observation but lacks the immersive aspect of participant observation.

Correct Answer: D

Rationale: Kathryn should consider giving birth at a freestanding birth center. Freestanding birth centers provide a setting where women can have more control over their labor and delivery experience, including the choice of delivery positions, the presence of family members and friends, and involvement in decision-making throughout the process. These centers offer a more home-like environment compared to hospitals while still providing access to medical support if needed. Choices A (private home) and B (local hospital) do not necessarily guarantee the level of control and facilities Kathryn seeks. While a doula center (Choice C) can provide additional support during labor, it may not offer the same level of medical facilities and control over the birthing process as a freestanding birth center.

Correct Answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.
