The healthcare provider prescribes epoetin alfa 8,200 units SUBQ for a client with chronic kidney disease (CKD). The 2 mL multidose vial is labeled, "Each 1 mL of solution contains 10,000 Units of epoetin alfa." How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth).
Answer and Explanation

The Correct Answer is ["0.8"]

Here's how to calculate the volume the nurse should administer:

Concentration of epoetin alfa: 10,000 units/mL (given on the vial label)

Prescribed dose: 8,200 units

We need to find the volume (in mL) that contains the prescribed dose (8,200 units) of epoetin alfa.

Dosage calculation:

Volume to administer (mL) = Dose (units) / Concentration (units/mL)

Volume to administer (mL) = 8,200 units / 10,000 units/mL

Volume to administer (mL) = 0.82 mL (round to nearest tenth as requested)

Therefore, the nurse should administer 0.8 mL.

Correct Answer is ["42"]

Explanation

Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:

1. Volume of azithromycin solution:

Volume = 500 mL (given)

2. Infusion duration:

Duration = 2 hours (given)

3. IV administration set gtt/mL:

Rate (gtt/mL) = 10 gtt/mL (given)

4. We need to find the rate (gtt/min) at which the solution should infuse to deliver the total volume (500 mL) over the specified duration (2 hours).

Steps:

a. Convert infusion duration from hours to minutes:

Duration (minutes) = Duration (hours) x Minutes per hour

Duration (minutes) = 2 hours * 60 minutes/hour

Duration (minutes) = 120 minutes

b. Calculate the total number of drops to be infused:

Total drops = Volume (mL) x Rate (gtt/mL)

Total drops = 500 mL * 10 gtt/mL

Total drops = 5,000 drops

c. Calculate the infusion rate (gtt/min):

Infusion rate (gtt/min) = Total drops / Duration (minutes)

Infusion rate (gtt/min) = 5,000 drops / 120 minutes

Infusion rate (gtt/min) = 41.67 gtt/min (round to nearest whole number as requested)

Therefore, the nurse should regulate the infusion at approximately 42 gtt/min.

Correct Answer is ["0.5"]

Explanation

Here's how to calculate the volume the nurse should administer after reconstituting the medication:

1. Reconstitution and Concentration:

The medication label states adding 2.5 mL of normal saline will make a solution with a concentration of 1 gram per mL. This means after reconstituting, each 1 mL of the solution will contain 1 gram of medication.

2. Dose conversion:

The client's prescription is for 500 mg. We need to convert it to grams since the concentration is in grams per mL.

Conversion: 1 gram (g) = 1000 milligrams (mg)

Prescribed dose (g) = 500 mg / 1000 mg/g

Prescribed dose (g) = 0.5 g (round to nearest tenth)

3. Calculate the volume to administer:

We know the concentration after reconstitution (1 gram/mL) and the desired dose in grams (0.5 g).

Volume to administer (mL) = Dose (g) / Concentration (g/mL)

Volume to administer (mL) = 0.5 g / 1 g/mL

Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)

Therefore, the nurse should administer approximately 0.5 mL of the reconstituted medication to the client.
