The order from a provider is: Administer Penicillin 3 gm IV on call to OR over 1 hour. The pharmacy provides Penicillin 3 gm diluted in 150 mL of NS. The drop factor is 10 gtt/mL. What is the gtt/min

Answer and Explanation

The Correct Answer is ["25"]

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

Correct Answer is ["133"]

Explanation

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 ["250"]

Explanation

To calculate the rate for an infusion pump, you would use the formula: rate (mL/hr) = volume to be infused (mL) / time for infusion (hr). In this case, the volume to be infused is 500 mL and the time for infusion is 2 hours. Therefore, the infusion pump rate would be calculated as 500 mL divided by 2 hours, resulting in a rate of 250 mL/hr.
