What should the nurse do before administering potassium chloride intravenously?

Before administering potassium chloride intravenously, it is essential to dilute the solution prior to the infusion. Potassium chloride is a potent electrolyte that can cause significant adverse effects if given too quickly or in a concentrated form. Administering it undiluted or as a bolus can lead to complications such as hyperkalemia, cardiac arrhythmias, or damage to the venous system.

Diluting potassium chloride helps ensure that it is given safely and effectively, allowing for gradual correction of potassium levels in the body. The dilution process is critical for controlling the rate of infusion and minimizing the risk of irritation to the vein. Standard practice often involves mixing potassium chloride with a compatible intravenous fluid, such as normal saline or dextrose solution, in appropriate proportions before administering it to the patient.

Monitoring for compatibility with other medications is also important, but the primary focus should be on ensuring the potassium chloride is diluted properly to maintain patient safety during administration.
