The health-care provider prescribes penicillin 700,000 Units IM daily. The available vial is labeled, Penicillin 500,000 Units/ml. How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
To calculate the volume of penicillin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (Units) / Concentration (Units/mL)
Plugging in the given values:
Volume (mL) = 700,000 Units / 500,000 Units/mL
Calculating the result:
Volume (mL) = 1.4 mL
Therefore, the nurse should administer 1.4 mL of penicillin.

Correct Answer is ["33"]
Explanation
Step 1: Calculate the concentration of the medication:
Concentration (mg/mL) = Total Medication (mg) / Total Volume (mL)
Concentration = 2000 mg / 100 mL
Concentration = 20 mg/mL
Step 2: Calculate the infusion rate in mg/minute:
Infusion Rate (mg/minute) = Infusion Rate (mL/hour) x Concentration (mg/mL) x (1 hour / 60 minutes)
Infusion Rate = 100 mL/hour x 20 mg/mL x (1 hour / 60 minutes)
Infusion Rate = 33.33 mg/minute
Rounding to the nearest whole number, the client is receiving 33 mg of medication per minute.
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.
