The order from the provider is: start a maintenance dose of magnesium sulfate of 4 g per hour. The pharmacy provides you with a 1 liter bag with 30 g of magnesium sulfate added. What is the rate on the infusion pump of the maintenance dose?

Answer and Explanation

The Correct Answer is ["133"]

To calculate the infusion pump rate for a maintenance dose of magnesium sulfate, you need to determine how many milliliters per hour (mL/hr) will provide 4 grams (g) of magnesium sulfate per hour. Given that the pharmacy provides a 1-liter bag with 30 g of magnesium sulfate, this means there are 30,000 milligrams (mg) in 1,000 milliliters (mL) of solution. Since 1 g equals 1,000 mg, you need to administer 4,000 mg of magnesium sulfate per hour. To find the rate, divide the total amount of magnesium sulfate in the bag by the desired hourly dose: 30,000 mg divided by 4,000 mg per hour equals 7.5 hours of infusion time. Therefore, to administer the maintenance dose over one hour, you would set the infusion pump to 1,000 mL divided by 7.5 hours, which equals approximately 133.33 mL/hr = 133 mL/hr rounded off to the nearest whole number.

Correct Answer is ["83"]

Explanation

To calculate the rate for an infusion pump, you would divide the total volume of fluid to be infused by the number of hours over which the infusion is to run. In this case, you have 1 liter (1,000 milliliters) of Normal Saline (NS) to be infused over 12 hours. Therefore, the rate would be 1,000 milliliters divided by 12 hours, which equals approximately 83.33 milliliters per hour. So, you would set the infusion pump to deliver at a rate of 83 milliliters per hour to ensure the 1L of NS is infused over the prescribed 12-hour period.

Correct Answer is ["25"]

Explanation

Total Penicillin dose: 3 gm (as given in the order)

Available volume: The pharmacy provides 150 mL of NS with the Penicillin already diluted.

Infusion time: 1 hour.

Rate (mL/min) = Total volume (mL) / Total time (minutes)

1 hour = 60 minutes

Rate (mL/min) = 150 mL / 60 minutes = 2.5 mL/min

Drop factor: The drip factor is 10 gtt/mL, meaning 10 drops deliver 1 mL of solution. Rate (gtt/min): To find the rate in gtt/min, multiply the rate (mL/min) by the drip factor (gtt/mL).

Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)

Rate (gtt/min) = 2.5 mL/min x 10 gtt/mL = 25 gtt/min
