The order from a provider is: Vancomycin 2 g in 500 mL of d5W IV daily to be administered over 2 hours. What is the rate on the infusion pump?
The Correct Answer is ["250"]
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.

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 ["2525"]
Explanation
To calculate the total intake of the client, the nurse would add up all the fluids administered over the past 9 hours. The lactated Ringer's IV, which was given at a rate of 150 mL/hr for 9 hours, totals 1350 mL. The cefazolin was administered in 100 mL of 0.9% sodium chloride, and since it's an intermittent bolus, we count it once, adding 100 mL. The two units of packed RBCs add up to 525 mL (275 mL + 250 mL). The two IV bolus infusions of 0.9% sodium chloride are 500 mL in total (250 mL each). Lastly, the famotidine was given in 50 mL of 0.9% sodium chloride. Adding all these together, the nurse should record a total intake of 2525 mL for the client over the past 9 hours.
