When preparing items for a client receiving magnesium sulfate IV, which item is the highest-priority to have readily available?

• A. Calcium gluconate injection
• B. Tongue blade
• C. Percussion hammer
• D. Potassium chloride injection

Answer: (A)

Magnesium sulfate can cause toxicity that depresses neuromuscular function and respiration, so having a specific antidote ready is essential. Calcium gluconate reverses magnesium’s effects and rapidly restores neuromuscular function and breathing, making it the critical item to have available when a client is on MgSO4. This allows a swift response if signs of toxicity appear, such as diminished or absent reflexes or slowed breathing. The other items don’t address MgSO4 toxicity: a tongue blade is an airway aid, not a treatment; a percussion hammer is just for checking reflexes; and potassium chloride is unrelated to MgSO4 management and could be harmful if used inappropriately.
