A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is Tobramycin 40 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2.1"]

To calculate the amount of tobramycin that the nurse should administer per dose, we can use the following steps:

Calculate the total daily dosage required based on the client's weight and the prescribed dosage.

Determine the dosage per each of the three divided doses.

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution.

Given:

Client's weight = 85 kg

Prescribed dosage = 3 mg/kg/day

Available concentration of tobramycin = 40 mg/mL

Let's calculate step by step:

Calculate the total daily dosage required:

Total daily dosage = 3 mg/kg/day × 85 kg = 255 mg/day

Determine the dosage per each of the three divided doses:

Dosage per dose = Total daily dosage / 3 = 255 mg / 3 = 85 mg

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution:

Volume of drug per dose = Dosage per dose / Concentration of tobramycin

Volume of drug per dose = 85 mg / 40 mg/mL ≈ 2.1 mL

Rounding to the nearest tenth, the nurse should administer 2.1 mL of the tobramycin per dose.

Explanation

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

Calculate the total number of minutes for the infusion:

8 hours × 60 minutes/hour = 480 minutes

Determine the total number of drops needed for the infusion:

The total volume to be infused is 1000 mL.

The drop factor is 15 gtt/mL.

1000 mL × 15 gtt/mL = 15000 gtt

Calculate the IV flow rate in drops per minute:

15000 gtt ÷ 480 min ≈ 31 gtt/min

Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

Correct Answer is ["0.7"]

Explanation

To calculate the amount of epoetin to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))

Plugging in the given values:

Amount to administer (mL) = (7,000 units / 10,000 units/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (7,000 / 10,000) = 0.7 mL

So, the nurse should administer 0.7 mL of epoetin subcutaneously for the management of anemia related to chronic kidney disease.
