A nurse is preparing to administer penicillin G potassium 1,000,000 units intermittent IV bolus. The label on the vial indicates to reconstitute with 50 ml of sterile water to make penicillin G potassium 100,000 units/ml. How many ml, should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["10"]

To determine how many milliliters (mL) of the reconstituted penicillin G potassium to administer, you can use the following calculation:

Given:

  • Reconstituted concentration: 100,000 units/mL
  • Total dose to be administered: 1,000,000 units

Now, use the formula:

Volume (mL) = Total dose (units) / Concentration (units/mL)

Volume (mL) = 1,000,000 units / 100,000 units/mL

Volume (mL) = 10 mL

So, the nurse should administer 10 mL of the reconstituted penicillin G potassium.

Explanation

To calculate the flow rate in drops per minute (gtt/min) for the IV infusion of clindamycin, you can use the following formula:

Flow rate (gtt/min) = (Volume to be infused (mL) * Drop factor) / Time (minutes)

First, you need to determine the volume to be infused. In this case, it's 100 mL. The drop factor is given as 15 gtt/mL, and the time is 60 minutes (1 hour).

Now, plug these values into the formula:

Flow rate (gtt/min) = (100 mL * 15 gtt/mL) / 60 minutes

Flow rate (gtt/min) = (1500 gtt) / 60 minutes

Flow rate (gtt/min) = 25 gtt/min

So, the nurse should set the flow rate to deliver 25 gtt/min for the IV infusion of clindamycin.

Correct Answer is C

Explanation
