Question

Quizplus · Accepted Answer

Renal failure is the most likely cause of hypermagnesemia because the kidneys are responsible for filtering and excreting magnesium from the body. If the kidneys are not functioning properly, magnesium can accumulate in the blood leading to hypermagnesemia. Nasogastric tubes to suction and the use of mechanical ventilators are not typically associated with hypermagnesemia. Overzealous administration of I.V. potassium chloride can lead to hyperkalemia, but not hypermagnesemia.
