Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. In this case, with 20 grams of magnesium sulfate in 500 mL of solution, there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. This calculation ensures the correct dose is delivered within the specified time frame.

It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding.
