How should Magnesium Sulfate be prepared for administration?

The preparation and administration of Magnesium Sulfate are critical in emergency medical protocols, especially when addressing conditions such as pre-eclampsia or severe asthma exacerbations. The selected choice involves mixing 2 grams of Magnesium Sulfate in 50 mL of D5W (Dextrose 5% in Water) or Normal Saline (NS), which is a standard concentration for this medication.

Administering at a rate of 60 gtts/min (drops per minute) strikes a balance between ensuring the medication is delivered effectively without overwhelming the body too quickly, which could lead to adverse effects. This rate promotes a controlled infusion that allows for adequate therapeutic levels of Magnesium Sulfate in the bloodstream.

Using a dilution of 50 mL helps in reducing the risk of local venous irritation and ensures a more gradual systemic absorption of the medication. The option emphasizes key principles of intravenous administration, including appropriate concentration and infusion rates to optimize patient safety and efficacy of the treatment.
