1. 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?

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.

2. The parents of a child with acute postinfectious glomerulonephritis (APIGN) ask how they will know that the condition is improving. How should the nurse respond?

Correct answer: A

Rationale: Improvement in APIGN is indicated by an increase in urine output and a change in urine color from brown (due to hematuria) to a more normal appearance. This reflects a reduction in glomerular inflammation and improved kidney function. Choice B is incorrect because resting more comfortably is not a direct indicator of kidney function improvement. Choice C is incorrect because a decrease in appetite is not typically associated with improvement in APIGN. Choice D is incorrect because an increased BUN value would suggest worsening kidney function rather than improvement.

3. The nurse suspects fluid overload in an infant receiving intravenous fluids. What clinical manifestation is suggestive of water intoxication?

Correct answer: C

Rationale: Water intoxication can lead to cerebral edema, causing neurological symptoms such as irritability and seizures. Oliguria, weight loss, and muscle weakness are not typical signs of water intoxication.

4. When auscultating an infant's lungs, the nurse detects diminished breath sounds. What should the nurse interpret this as?

Correct answer: C

Rationale: Diminished breath sounds in an infant are an abnormal finding and warrant further investigation to rule out conditions like atelectasis or pneumonia.

5. The nurse is caring for a non-English-speaking child and family. Which should the nurse consider when using an interpreter?

Correct answer: C

Rationale: The nurse should communicate directly with the family members when asking questions, ensuring the interpreter translates accurately without adding or omitting information.
