Final answer:
To address hypermagnesemia, nursing interventions include administering calcium gluconate, restricting magnesium-rich foods in the diet, and avoiding magnesium supplements.
Step-by-step explanation:
To address hypermagnesemia, nursing interventions should focus on reducing the magnesium levels in the body. One of the interventions is administering calcium gluconate to block the cardiac effects of hypermagnesemia. Calcium gluconate helps counteract the hypotension and cardiac dysrhythmias that can occur due to high magnesium levels.
Another intervention is to restrict magnesium-rich foods in the patient's diet. This includes foods like nuts, legumes, whole grains, and certain vegetables. By limiting the intake of magnesium-rich foods, the body's magnesium levels can be gradually reduced.
It is important to note that administering magnesium supplements would be contraindicated in this scenario as it would further increase the magnesium levels, worsening the condition.
