Peripheral veins are generally capable of tolerating solutions with a lower concentration of dextrose, such as 5% dextrose, but typically, they can handle 10% dextrose under certain conditions. This capability stems from the osmolarity of the solution and the overall tolerance of peripheral veins to hypertonic solutions.

When the concentration of dextrose reaches 10%, the solution becomes more hypertonic, which can pose a risk for irritation, phlebitis, or infiltration. However, if the infusion is performed properly, with a suitable rate and appropriate vein selection to reduce irritation, a peripheral vein can tolerate a 10% dextrose solution.

Thus, it is accurate to say that peripheral veins can tolerate 10% dextrose, particularly when considering factors such as the speed of infusion, vein condition, and duration of the therapy, which all play important roles in minimizing potential complications.
