Pediatric ATI Practice Exam

What is the normal pediatric sodium level range?

1. 120-130

2. 134-150

3. 150-160

4. 160-170

The correct answer is: 134-150

The normal pediatric sodium level range is generally accepted to be between 134 to 150 milliequivalents per liter (mEq/L). Sodium is an essential electrolyte in the body, playing a critical role in maintaining fluid balance, nerve function, and muscle contraction. In children, levels can be slightly different than in adults due to various factors including developmental stage and hydration status. Understanding these normal ranges is crucial for identifying potential electrolyte imbalances, which can have significant implications for a child's health. For instance, hyponatremia (low sodium levels) can lead to symptoms such as lethargy, irritability, or even seizures, while hypernatremia (high sodium levels) can cause thirst, confusion, and can be indicative of dehydration or other underlying health issues. The other ranges presented do not align with normal pediatric values. Levels that fall below or rise above the accepted range could indicate medical issues that necessitate further investigation and management.
