The approach to managing hyperkalemia often includes the administration of IV fluids with dextrose, particularly when combined with insulin. This treatment works effectively to lower serum potassium levels. Dextrose can stimulate the release of insulin, which, in turn, facilitates the uptake of potassium into cells, thus helping to reduce the elevated levels in the bloodstream.

This treatment is commonly employed in emergency settings to quickly address dangerous potassium levels, as hyperkalemia can lead to serious cardiac complications. IV fluids also help promote renal excretion of potassium, further aiding in the reduction of hyperkalemia.

The incorrect choices do not contribute to the management of hyperkalemia in the same way. For instance, calcium supplements might be used to protect the heart in acute hyperkalemia, but they do not lower potassium levels. Fluid restrictions are contraindicated since hydration is important to promote urinary potassium excretion. Increased potassium intake would exacerbate the condition rather than treat it.
