What is the standard reference range for pediatric magnesium levels?

1.0-1.3
1.4-1.7
1.7-2.0
2.0-2.5

The correct answer is: 1.4-1.7

The standard reference range for pediatric magnesium levels is typically considered to be between 1.4 and 1.7 mg/dL. This range is important because magnesium plays a critical role in many body functions, including neuromuscular conduction, muscle contraction, and blood pressure regulation. Maintaining levels within this range is essential for optimal physiological functioning in children. While levels outside this range might indicate deficiencies or excesses, it's vital for healthcare professionals to interpret magnesium levels in the context of the overall clinical picture, including the child’s dietary intake, any underlying medical conditions, and other electrolyte levels. Ensuring that magnesium levels are monitored can help prevent complications related to both low and high magnesium levels.
