Higher concentrations of IV potassium are damaging to the smaller peripheral veins. Electrolyte supplements - Potassium is essential for transmission of nerve impulses, contraction of cardiac muscle, maintenance of intracellular tonicity, skeletal and smooth muscles, and maintenance of normal renal function. These agents increase the body's potassium level. Hypokalemia may result from the movement of potassium into cells without loss of potassium from the body. Higher dosages may increase risk of cardiac complications.
Many institutions have policies that limit maximum amount of potassium that can be given per hour.
Available in liquid, powder, or tablet form. Any form may irritate the stomach and cause vomiting. Should be taken with food or after meals to minimize GI discomfort. Continue IV replacement of potassium as needed. Continue cardiac monitoring in severe hypokalemia.
