ATI Nursing Care of Children
1. A major reason for the development of respiratory distress syndrome in the preterm infant is:
- A. Excessive surfactant
- B. Lack of surfactant
- C. Immature immune system
- D. Lack of body fat
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.
2. The nurse is reviewing the importance of role learning for children. The nurse understands that children's roles are primarily shaped by which members?
- A. Peers
- B. Parents
- C. Siblings
- D. Grandparents
Correct answer: B
Rationale: Parents play the primary role in shaping their children's roles and behaviors, especially in early childhood, through modeling, guidance, and expectations.
3. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?
- A. High serum pH
- B. Normal serum pH
- C. Metabolic alkalosis
- D. Metabolic acidosis
Correct answer: D
Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.
4. When assessing a preschooler's chest, what should the nurse expect?
- A. Respiratory movements to be chiefly thoracic
- B. Anteroposterior diameter to be equal to the transverse diameter
- C. Retraction of the muscles between the ribs on respiratory movement
- D. Movement of the chest wall to be symmetric bilaterally and coordinated with breathing
Correct answer: D
Rationale: In a preschooler, chest movement should be symmetric and coordinated with breathing, indicating healthy respiratory function.
5. According to Piaget, which principle supports a nine-year-old child's understanding that an arm will look the same when the IV is removed?
- A. The principle of conservation
- B. The principle of transductive reasoning
- C. The principle of identity
- D. The principle of reflex abilities
Correct answer: A
Rationale: The correct answer is A, the principle of conservation. Piaget's principle of conservation relates to a child's ability to understand that certain properties of objects remain unchanged despite modifications in their appearance. In this case, the child's understanding that an arm will look the same after the IV is removed demonstrates conservation of appearance. Choice B, transductive reasoning, involves making faulty generalizations based on specific instances and does not apply in this context. Choice C, the principle of identity, pertains to recognizing objects as the same even if they undergo transformations, which is not directly relevant to the scenario. Choice D, reflex abilities, refers to automatic responses to stimuli and is unrelated to the child's understanding of the arm's appearance post-IV removal.
