Pediatric ATI Practice Exam

What is the normal range for pediatric potassium levels?

1. 3.5-4.5

2. 4.1-5.3

3. 5.3-6.5

4. 6.5-7.5

The correct answer is: 4.1-5.3

The normal range for potassium levels in pediatric patients, which is crucial for numerous bodily functions including muscle contraction and nerve function, typically falls between 4.1 and 5.3 mEq/L. Values within this range are essential for maintaining cellular homeostasis and overall health in children. Values below or above this range can indicate various health issues; for example, hypokalemia (low potassium) can lead to muscle weakness and cardiac problems, while hyperkalemia (high potassium) can also pose serious risks, particularly related to cardiac function. This is why it's vital for healthcare providers to monitor potassium levels closely in pediatric patients – especially those with conditions that could affect electrolyte balance.
