Correct Answer: A

Rationale: The most appropriate nursing intervention for a 7-year-old child with acute glomerulonephritis experiencing gross hematuria and bed rest is to provide activities for the child on restricted activity. Although the child may feel well, it is essential to limit activity until hematuria resolves to prevent complications and promote recovery.

Correct Answer: B

Rationale: Turning and repositioning the infant every 4 hours is essential to prevent pressure sores and ensure uniform exposure to phototherapy. This practice helps prevent skin breakdown and ensures the effectiveness of the phototherapy in treating hyperbilirubinemia.

Correct Answer: D

Rationale: The correct answer is D: BP of 70/50. When sildenafil (Viagra) is taken with nitroglycerin, it can cause severe hypotension that is unresponsive to treatment. The combination of these medications can lead to a dangerous drop in blood pressure. It is crucial to immediately report hypotension in this scenario. It is recommended to allow at least 24 hours to elapse between the last dose of sildenafil and nitroglycerin to prevent such adverse effects. The other vital signs and lab values may be abnormal but do not have the immediate life-threatening implications that severe hypotension does in this context.

Correct Answer: A

Rationale: The child with tachypnea and pulmonary congestion should be seen first as these symptoms indicate a more severe form of fluid-volume excess that requires immediate attention. Tachypnea is an increase in respiratory rate, which could be a sign of respiratory distress, and pulmonary congestion indicates fluid accumulation in the lungs, posing a significant risk to the child's respiratory function.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid administering NSAIDs.' Hemophilia is a condition where blood does not clot properly. NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) can increase the risk of bleeding in individuals with hemophilia. Therefore, it is crucial for the parent to avoid giving their child NSAIDs for pain management to prevent exacerbating bleeding tendencies.
