Which of the following should NOT be performed when administering IV potassium chloride?

When administering IV potassium chloride, it is essential to adhere to safe administration practices to prevent serious complications. Administering potassium chloride as an IV bolus is highly discouraged. This is because bolus administration can lead to rapid increases in serum potassium levels, which may cause hyperkalemia, resulting in potentially life-threatening cardiac arrhythmias. The safe administration of potassium chloride requires a controlled infusion method to ensure that the rate of potassium entering the bloodstream is gradual and closely monitored.

Using an infusion pump for administration, verifying medication compatibility with IV fluids, and administering potassium via a peripheral line are all appropriate practices that help ensure patient safety. An infusion pump allows for precise control over the rate of administration, reducing the risk of complications. Verifying compatibility is crucial to prevent adverse reactions with other medications or fluids. While potassium can be administered through a peripheral line, it should be noted that concentrations above a certain threshold typically require central venous access to prevent local irritation and ensure a safer delivery method.
