A nurse is preparing to administer heparin 7,500 units subcutaneous. Available is heparin 10,000 units/mL. How many ml. should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["0.75"]

To calculate the volume of heparin (in milliliters) to administer, you can use the following formula:

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

In this case, the desired dose is 7,500 units, and the concentration is 10,000 units/mL.

Volume (mL) = 7,500 units / 10,000 units/mL

Volume (mL) = 0.75 mL

So, the nurse should administer 0.75 mL of heparin.

Correct Answer is ["83"]

Explanation

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

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

Given:

  • Volume to be infused = 250 mL
  • Time in minutes = 30 minutes
  • Drop factor = 10 gtt/mL

Now, plug these values into the formula:

Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL

Flow rate (gtt/min) = (8.33) * 10

Flow rate (gtt/min) ≈ 83.3

Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.

Correct Answer is ["25"]

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.
