The nurse is preparing to administer vancomycin (Vancocin) 750 mg in 250 ml of Dextrose 5% in Water (D,W) over 75 minutes. The secondary infusion pump should be programmed to administer how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["200"]
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
First, convert minutes to hours:
75 minutes x (1 hour / 60 minutes) = 1.25 hours
Then, plug in the values into the formula:
Infusion Rate = 250 mL / 1.25 hours
Calculating the result:
Infusion Rate ≈ 200 mL/hour
Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.

Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 500 mg = 1 tablet / 250 mg
Cross-multiplying:
250x = 500
Solving for x:
x = 500 / 250
x = 2
Therefore, the nurse should administer 2 tablets of azithromycin per dose.
Correct Answer is ["2000"]
Explanation
To calculate the infusion rate of magnesium sulfate, we'll follow these steps:
1. Calculate the concentration of magnesium sulfate in the IV solution:
Magnesium Sulfate Concentration = Magnesium Sulfate (g) / Solution Volume (mL)
Magnesium Sulfate Concentration = 4 grams / 250 mL
Magnesium Sulfate Concentration = 16 mg/mL
2. Calculate the magnesium sulfate infusion rate in mg/hour:
Magnesium Sulfate Infusion Rate = Infusion Rate (mL/hour) x Magnesium Sulfate Concentration (mg/mL)
Magnesium Sulfate Infusion Rate = 125 mL/hour x 16 mg/mL
Magnesium Sulfate Infusion Rate = 2000 mg/hour
Therefore, the nurse should administer 2000 mg/hour of magnesium sulfate.
