The nurse is caring for a client diagnosed with heart failure who has a magnesium level of 0.75 mEq/L (0.375 mmol/L). Which action should the nurse take?

The normal magnesium level ranges from 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L); therefore, this client is experiencing hypomagnesemia. The client should be monitored for dysrhythmias because magnesium plays an important role in myocardial nerve cell impulse conduction; thus, hypomagnesemia increases the client's risk of ventricular dysrhythmias. The nurse avoids administering phosphate in the presence of hypomagnesemia because it aggravates the condition. The nurse instructs the client to consume foods high in magnesium; ground beef, eggs, and chicken breast are low in magnesium.
