Clinical Nutritionist Practice Test

What is the max percentage of glucose allowed in a peripheral IV line?

1. 5%

2. 10%

3. 15%

4. 20%

The correct answer is: 10%

The maximum percentage of glucose allowed in a peripheral IV line is 10%. This concentration is significant because peripheral intravenous access is intended for short-term use, and higher concentrations of glucose can lead to potential complications such as hyperglycemia, tissue irritation, and thrombophlebitis. Glucose solutions higher than 10% often require central venous access, allowing for safer administration since central veins can accommodate higher osmolarity without causing irritation to the vessel. By adhering to this guideline, healthcare providers can minimize risks and ensure patient safety during intravenous therapy. Understanding these parameters is crucial for clinical nutritionists and healthcare professionals, as they inform appropriate fluid and nutritional interventions based on the patient's needs.
