Why is knowledge of developmental theories useful for the nurse?

Correct Answer: D

Rationale: The correct answer is D. Understanding developmental theories helps nurses anticipate and plan appropriate care based on the child's developmental stage. Choice A is incorrect because developmental theories provide a framework but do not dictate exact actions. Choice B is incorrect as developmental processes are not entirely predictable and are not meant to control a child's development. Choice C is incorrect as developmental theories are not a strict set of facts that all children follow in a prescribed manner, but rather guidelines for understanding and supporting a child's growth and development.

Correct Answer: C

Rationale: During a hospital stay, preschool children may exhibit regression in behaviors such as bed-wetting due to stress. It is important for parents to understand that this behavior is a common response to the hospital environment and should resolve once the child is back home. Therefore, the correct explanation for the nurse to provide to the parents is choice C. Choice A is incorrect because it inaccurately states that the child is no longer potty-trained. Choice B is incorrect as it assumes a medical issue without evidence. Choice D is incorrect as it dismisses the parents' concerns without addressing the underlying cause of the behavior.

Correct Answer: C

Rationale: For a 2-day-old neonate, the most suitable method to measure temperature is the axillary method. This approach is considered safe and appropriate for neonates, minimizing the risk of injury. Tympanic temperature measurement may not be as accurate in neonates due to their small ear canals. Oral temperature measurement is not recommended for neonates as they may not be able to hold a thermometer properly in their mouths. Rectal temperature measurement is invasive and carries a higher risk of injury and should be avoided unless absolutely necessary.

Correct Answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.

Correct Answer: B

Rationale: The correct answer is B, symbolic functioning. Symbolic functioning refers to children using objects, actions, or ideas to represent other objects, actions, or ideas. In this scenario, pretending a sheet is a cape to mimic a superhero demonstrates the child's ability to engage in symbolic play. Choice A, artificialism, is incorrect as it refers to the belief that inanimate objects have lifelike qualities. Choice C, critical thinking, does not directly relate to the imaginative play described in the question. Choice D, dramatic play, is close but not as precise as symbolic functioning, which specifically highlights the use of objects to represent something else.
