Through a peripheral line, max % of dextrose that can be given is?
**Core Concept**
The question is testing the safe administration of dextrose through a peripheral intravenous line, which involves understanding the maximum concentration of dextrose that can be safely infused without causing phlebitis or other complications.
**Why the Correct Answer is Right**
The correct answer is based on the principle of minimizing the risk of phlebitis and thrombophlebitis when administering dextrose through a peripheral line. A concentration of 10% dextrose is the maximum recommended, as higher concentrations can cause irritation and inflammation of the vein, leading to phlebitis. This is because the osmotic pressure of dextrose solutions increases with concentration, and high concentrations can cause fluid shift and damage to the endothelial lining of the vein.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because a 25% dextrose solution is too concentrated and can cause severe phlebitis and thrombophlebitis.
**Option B:** This option is incorrect because a 50% dextrose solution is even more concentrated and can cause severe damage to the vein, leading to thrombosis and tissue necrosis.
**Option C:** This option is incorrect because a 5% dextrose solution is too dilute to cause significant phlebitis, but it may not provide sufficient calories or osmotic support.
**Clinical Pearl / High-Yield Fact**
When administering dextrose through a peripheral line, it's essential to use the lowest concentration necessary to achieve the desired effect, as higher concentrations can increase the risk of phlebitis and other complications.
**Correct Answer:** C. 10%
