Question

The order is to infuse 1grams/hr of 50% magnesium sulfate. The solution available is 25 grams of 50% magnesium sulfate in 250 mLD5 W. What flow rate in mL/hr would be needed to administer the required dose?

Answer 1

To administer the required dose of 1 gram/hour of 50% magnesium sulfate, a flow rate of 10 mL/hr is needed.

Step-by-step explanation:

To infuse 1 gram/hour of 50% magnesium sulfate, we need to determine the flow rate in mL/hr needed to administer the required dose.

First, we need to find the number of grams of magnesium sulfate in the solution available. The solution contains 25 grams of 50% magnesium sulfate in 250 mL of D5W solution (5% dextrose in water).

Now, we can use the given information to calculate the flow rate in mL/hr using the equation:

Flow rate (mL/hr) = (Dose in grams/hr) / (Concentration in grams/mL)

Flow rate = 1 gram/hour / (25 grams / 250 mL) = 10 mL/hr
