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 ["1.5"]

Explanation

First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:

Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg

Now we can calculate the volume (mL) required for the dose:

Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution

Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.

Correct Answer is ["60"]

Explanation

To calculate the IV flow rate in gtt/min, you can use the following formula:

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

In this case, the volume to be infused is 60 mL/hr, the drop factor is 60 gtt/mL, and we want to find the flow rate in gtt/min.

Flow rate (gtt/min) = (60 mL/hr x 60 gtt/mL) / 60 min

Flow rate (gtt/min) = (3600 gtt/hr) / 60 min

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