Question

The order is to infuse 1grams/hr of 50% magnesium sulfate. The solution available is 25 grams of 50% magnesium sulfate in 250 mL D 5 W. What flow rate in mL/hr would be needed to administer the required dose?

Answer 1

The flow rate needed to administer the required dose of 1 gram/hr of 50% magnesium sulfate is 2 mL/hr.

Step-by-step explanation:

To determine the flow rate needed to administer the required dose of 1 gram/hr of 50% magnesium sulfate, we need to calculate the flow rate in mL/hr. We have a solution available that contains 25 grams of 50% magnesium sulfate in 250 mL of D5W.

First, we need to calculate the amount of magnesium sulfate in grams that is present in the 250 mL solution. Since the solution is 50% magnesium sulfate, we can multiply 250 mL by 50% to get 125 grams of magnesium sulfate in the solution.

Next, we can use the formula:

Flow rate (mL/hr) = Required dose / Concentration

Flow rate (mL/hr) = 1 gram/hr / 125 grams/250 mL

Flow rate (mL/hr) = 2 mL/hr

Therefore, the flow rate needed to administer the required dose is 2 mL/hr.
