Question

A post-chemotherapy client is experiencing hypokalemia and has an order for intravenous potassium chloride 10 mEq in 100 mL of normal saline. Which does the nurse select as the most appropriate means to deliver this medication? ? A. The largest antecubital vein ? B. The vein in the back of the dominant hand ? C. The cephalic vein ? D. A vascular access device

Short answer

Answer: D. A vascular access device

Step-by-step solution

Examining each option

Let's take a closer look at each choice to determine their suitability for delivering intravenous potassium chloride. -A. The largest antecubital vein -B. The vein in the back of the dominant hand -C. The cephalic vein -D. A vascular access device

Option A: The largest antecubital vein

This vein is typically used for drawing blood and is not the best option for administering intravenous potassium chloride. Potassium chloride can be a highly irritating solution, so it is not ideal to administer it through a peripheral vein that is prone to movement and more visible.

Option B: The vein in the back of the dominant hand

Administering potassium chloride through a peripheral vein in the hand is not ideal due to the irritating nature of the medication. Additionally, using the dominant hand may cause discomfort to the patient while the infusion is taking place.

Option C: The cephalic vein

The cephalic vein is a viable option for administering intravenous potassium chloride, as it is a larger, more stable vein. However, it may still cause irritation and discomfort to the patient and is not the most recommended site for this type of infusion.

Option D: A vascular access device

A vascular access device, such as a PICC (Peripherally Inserted Central Catheter) or central venous catheter, is the most appropriate choice for administering intravenous potassium chloride. These devices facilitate distribution into larger veins and allow for better dilution of the medication, reducing the risk of irritation and providing a more comfortable experience for the patient.

Conclusion

Based on our assessment, the most appropriate means to deliver intravenous potassium chloride 10 mEq in 100 mL of normal saline to a post-chemotherapy client experiencing hypokalemia is: ? D. A vascular access device
