Why must IV potassium be diluted and run through a pump?

• A. To prevent tissue irritation and control the administration rate
• B. To prevent contamination
• C. To ensure bitter taste
• D. To shorten infusion time

Answer: (A)

Potassium chloride given IV must be diluted and delivered with an infusion pump because it is a caustic, high-concentration electrolyte that can irritate a vein and surrounding tissue if given undiluted or too quickly. Diluting reduces venous irritation and the risk of infiltration or phlebitis, while the infusion pump provides precise, controlled delivery to avoid dangerous spikes in potassium levels. A rapid push or overly fast infusion can lead to life-threatening hyperkalemia and arrhythmias, so the combination of dilution and pump-controlled rate keeps administration safe and within prescribed parameters.
